Speech Assessments in Hypoplastic Cleft Maxilla Treated by Anterior Segmental Distraction Osteogenesis

Introduction: Cleft lip and palate (CLP) affect the craniofacial region, with significant implications for speech, hearing, feeding, and facial aesthetics. This study aimed to evaluate the impact of anterior maxillary segmental distraction osteogenesis (AMSDO) using an internal distractor on speech outcomes in CLP patients, assessed using the Pittsburgh Weighted Speech Scale (PWSS).Methodology: A single-center prospective study was conducted between March 2022 and April 2024. Twelve CLP patients with maxillary hypoplasia, aged 17.8 to 32.6 years, were included. Purposive sampling was done to include patients with complete unilateral or bilateral CLP who exhibited Class III skeletal relationships with reverse overjet greater than 7 mm. Speech assessments were conducted preoperatively (1-3 months before surgery) and postoperatively (5-7 months after distraction). Speech samples were recorded and evaluated by a licensed speech-language pathologist using the PWSS. Statistical analysis was performed using paired t-tests and Chi-square tests.Results: Significant improvements were observed in the total PWSS score (p = 0.03), nasality (p < 0.001), phonation (p < 0.001), and articulation errors (p = 0.004) postoperatively. No significant changes were seen in nasal emission and facial grimace. No correlation was found between the amount of distraction and speech outcomes. Unilateral cleft patients showed better outcomes than bilateral cleft patients, though not statistically significant.Conclusion: AMSDO significantly improves speech outcomes in CLP patients with maxillary hypoplasia. The PWSS is a reliable tool for assessing these changes. Further research with larger samples and longer follow-ups is warranted to confirm these findings.

Cochlear Implantation in Pediatric Cochlear Nerve Deficiency: A Systematic Review and Meta-Analysis.

Cochlear nerve deficiency (CND) is commonly implicated in moderate-to-profound pediatric sensorineural hearing loss (SNHL). Although cochlear implantation (CI) was previously contraindicated in CND patients, recent studies have demonstrated the potential for auditory response to CI in a subset of CND patients, though clinical outcomes remain variable. This study aims to evaluate pre- and postoperative speech and auditory outcomes of CI in pediatric patients with bilateral SNHL and radiographically confirmed CND. Embase and Ovid MEDLINE. A systematic review was conducted to identify studies reporting pre- and postoperative outcomes of children with CND confirmed by magnetic resonance imaging who underwent CI. A random-effects model was used to account for within- and between-study variance in speech and auditory outcomes. After abstract screening of 818 distinct articles, 16 studies were selected for final inclusion, consisting of 248 patients with cochlear nerve hypoplasia or aplasia who underwent CI. Various speech perception and language development tests were investigated across studies (Speech Intelligibility Rating, Speech Perception Category, Speech Awareness Thresholds, Meaningful Auditory Integration Scale, Meaningful Use of Speech Scale, Categories of Auditory Performance, and Auditory Level). Pooled outcomes demonstrated improvement in speech perception after CI in pediatric patients with CND (SMD 2.18, 95% CI 1.68-2.69). Indications for CI are expanding as research demonstrates benefit in populations previously thought inappropriate. Our study demonstrates global postoperative improvement in speech and auditory outcomes in children with bilateral SNHL and CND after CI. NA Laryngoscope, 2024.

Five-year long-term functional and quality of life outcomes in total glossectomy survivors.

Total glossectomy is proven to be a superior treatment option for advanced tongue cancer. Despite its efficacy, the procedure is associated with profound morbidity, notably impacting Speech, swallowing, and overall quality of life. Limited therapeutic benefits and the potential for considerable morbidity render total glossectomy a subject of controversy. We performed a multidimensional quality of life evaluation of long-term (more than 5 yrs.) total glossectomy survivors. In this study, we evaluated 25 total glossectomy survivors with comprehensive functional and quality of life outcomes using objective measures (London Speech Evaluation Scale, FOIS, 100ml Water Challenge, FEES) and Patient-reported outcomes (SHI, PSS HN, EORTC QLQ 30 & HN35). EORTC QLQ 30 showed overall good global health status (M = 80 ± 20) and functional scale mean scores ranging from 87 to 91, despite issues in pain (M = 31.6 ± 31), swallowing (M = 23.3 ± 24), and Speech (26.1 ± 1). Speech outcomes revealed 80% with moderate to severe intelligibility impairment. Swallowing outcomes showed 84% requiring special food preparation, 24% exhibiting aspiration, and 72% having pharyngeal residue. Speech outcomes showed 88% having moderate-severe speech impairment, and Patient-reported speech outcomes indicated a mean SHI score of (M = 47.2 ± 42). Patients undergoing total glossectomy report favourable long-term outcomes in global health-related quality of life despite moderate to severe impairments in objective speech and swallowing evaluations. These positive patient-reported outcomes support the consideration of total glossectomy as a viable treatment option if and when required, underscoring the importance of evaluating treatment outcomes through the patient-perceived quality of life.

Cleft Lip Scar Appearance is Associated With Speech Outcomes After Primary Palatoplasty.

This study aims to investigate the correlation between the quality of cleft lip scar and velopharyngeal insufficiency (VPI). Clinical photographs from 56 patients with repaired cleft lip and palate (CLP) were collected and anonymized by cropping the image to the region of interest around the lip and nose. A survey displaying each cleft lip scar image with five associated scar quality features, including scar color, thickness, width, lip shortening, and overall appearance, was distributed. Surveys were distributed using Amazon Mechanical Turk (MTurk), an online crowdsourcing platform, to obtain ratings from 330 laypeople. The same surveys were also distributed to 45 medical students. Hypernasality was used as the primary speech outcome measure. Ordinal logistic regression was used to compare the ratings for each of the five scar quality categories with the patients' CAPS-A-AM hypernasality rating for both MTurk and medical student raters. Significance was set at α = 0.05. For medical student ratings', ordinal logistic regression showed a statistically significant relationship between lip shortening (P=0.019) and overall appearance (P=0.044) with CAPS-A-AM hypernasality score, whereas the other scar categories showed no significant association. There was no statistically significant relationship between MTurk ratings and hypernasality for any of the scar categories. The association found between lip shortening and overall scar appearance, thought by the authors to indicate scar contracture, and hypernasality, an indicator of VPI severity, provides an interesting insight into how to potentially identify patients who may be at increased risk for developing VPI.

Management of velopharyngeal insufficiency by a new modification of sphincter pharyngoplasty technique in cleft palate patients, clinical and radiographical prospective study.

This study was designed to investigate the effectiveness and outcome of a new modification of the sphincter pharyngoplasty technique in the treatment of velopharyngeal insufficiency patients, with the determination of a specific dimension of velopharyngeal port and velum length of no hypernasality, snoring, and nasal regurgitation potential. The study included 10 patients, who were suffering from consistent hypernasal speech after failure of conservative speech therapy. Clinical and radiographic measurements of the velopharyngeal port and velum length before and after surgery were done, with clinical patient follow-up to assess snoring and nasal regurgitation after surgery for 1, 6, and 12 months. Before surgery, the mean clinical anteroposterior distance/velopharyngeal depth was 16.40±1.7mm, and the mediolateral distance was 20.20±3.4mm. After surgery, the mean anteroposterior distance decreased to 8±0.9mm, and the mean mediolateral distance decreased to 12.60±2.06mm. Both measurements showed statistically significant (P=0.0001). After 12 months postoperatively, the radiographic CT axial anteroposterior distance was 12.09±1.4mm, and the mean mediolateral distance was 19.82±5.6mm, compared to the mean CT anterioposterior before surgery 15.60±2mm and mediolaterally 21.28±2.7mm. The anteroposterior measurement showed a statistically significant (P=0.002), while the mediolateral measurement did not (P=0.3). The mean velum length before surgery was 25.80±1.5mm and 27.03±0.6mm after 12 months postoperatively. Snoring and nasal regurgitation occurrence were assessed at 1, 6, and 12 months postoperatively, with all reports being negative. Sphincter pharyngoplasty using posterior tonsillar pillars for treating VPI patients results in improved speech outcomes without snoring or nasal regurgitation.

Some Challenging Questions About Outcomes in Children With Cochlear Implants

Purpose: Cochlear implants (CIs) have improved the quality of life for many children with severe-to-profound sensorineural hearing loss. Despite the reported CI benefits of improved speech recognition, speech intelligibility, and spoken language processing, large individual differences in speech and language outcomes are still consistently reported in the literature. The enormous variability in CI outcomes has made it challenging to predict which children may be at high risk for limited benefits and how potential risk factors can be improved with interventions. In this article, we consider four challenging, unresolved issues that exist in the field of pediatric cochlear implantation (age at implantation, comorbid diagnoses, preimplant functioning in infants, and communication modality) to illustrate the value of adopting a broader integrated multidisciplinary approach to explaining variability and individual differences in outcomes. Conclusions: Four challenging and unresolved issues concerning our ability to predict individual differences before implantation were discussed. In order to address some of the current barriers to progress in dealing with these unresolved issues, a biopsychosocial system model is proposed as a possible unifying approach to conceptualizing these issues. Additionally, several new research directions to better understand and explain variability in pediatric CI outcomes are suggested.

Hearing, speech, and language outcomes in school-aged children after cleft palate repair.

Following primary cleft palate repair, individuals face a heightened risk of hearing problems, particularly conductive hearing loss, compensatory articulation disorders (CADs), resonance disorders, delayed speech and language development, and voice disorders. This study aimed to investigate the prevalence and impact of these challenges in children with cleft palate with or without cleft lip (CP± L). This cross-sectional study included 38 children with CP± L aged 5 to 13 years. A comprehensive evaluation involved audiological assessments (audiograms, tympanograms) by an audiologist and speech-language pathology assessments (Thai Speech Parameters for Patients with Cleft Palate, Articulation Screening Test) by speech-language pathologists. The prevalence of hearing loss affected 27.63% of participants (21 out of 76 ears) and majority of cases involved conductive hearing loss. Velar substitution was the most common CAD, followed by nasalized voiced pressure consonants, phoneme-specific nasal air emission, and pharyngeal substitution. A moderate correlation was found between these CAD patterns and hypernasality at the word, sentence, and screening levels (r= 0.44, p< 0.01; r= 0.43, p< 0.01; and r= 0.40, p= 0.01). For summary, the most common type of hearing loss was conductive hearing loss. The predominant CAD pattern was velar substitution. The protocol could be designed to enhance early improvement in hearing and articulation, thereby supporting academic achievement and long-term quality of life.

Child, family and professional views on valued communication outcomes for non-verbal children with neurodisability: A qualitative meta-synthesis.

There are many children with neurodisability who are unable to rely on speech to communicate and so use a range of augmentative and alternative communication (AAC) methods and strategies to get their message across. Current instruments designed to measure the outcomes of speech and language therapy interventions lack specific attention to communication outcomes that are valued by non-verbal children with neurodisability, their families and support networks. This qualitative meta-synthesis was conducted to identify valued communication outcomes to inform the next stage of developing a novel outcome measure. To systematically identify and synthesise the qualitative evidence about which communication outcomes non-verbal children with neurodisability, their family members, healthcare professionals and educators think are important to achieve, specifically which communication outcomes are most valued by: (1) non-verbal children with neurodisability; (2) parents or other family members of non-verbal children with neurodisability; and (3) professionals who work with non-verbal children with neurodisability. A systematic search of bibliographic databases and the grey literature was undertaken to identify qualitative studies that included evidence of views expressed by children, family members, healthcare professionals and educators on outcomes in relation to the communication of non-verbal children with neurodisability. All papers meeting the inclusion criteria were quality appraised using the Critical Appraisal Skills Programme Qualitative checklist, although none were excluded on this basis. The data synthesis involved organising coded data into descriptive themes which were then synthesised into analytical themes. We found 47 papers containing qualitative data meeting the inclusion criteria from research situated in 14 countries. The views of 35 children, 183 parents, six other family members, 42 healthcare professionals and 18 educators are represented in the review. The included studies contained very few data reported by children themselves; most data were provided by adults, especially parents. Three main analytical themes were identified: Experiences of communication and expectations; adapting to and acceptance of AAC; and becoming an autonomous communicator. This meta-synthesis brings together the limited qualitative research findings about what parents, professionals and children consider are important communication outcomes for non-verbal children with neurodisability. The synthesis identifies key gaps in our knowledge about the perspectives of children and their siblings. This synthesis will inform primary research to understand valued communication outcomes in this group, and ultimately the development of a patient-reported outcome measure (PROM) that can be used to demonstrate the effect of interventions, at both clinical and service levels. What is already known on the subject Studies of children with cerebral palsy and autism spectrum disorder indicate that at least 25% of children with these conditions are non-verbal. Studies on the health outcomes of children with neurodisability have identified that communication is rated as important by parents and health professionals. There is an evidence gap about which communication outcomes are important to non-verbal children, their families and the people who work with them. What this paper adds to the existing knowledge This is the first synthesis of data that relates to communication outcomes for non-verbal children with neurodisability. This qualitative meta-synthesis identifies from previous research studies the communication outcomes valued by children who are non-verbal, their parents or other family members, and the professionals who work with them. The findings will be used to shape further primary research and the development of a novel patient-reported communication outcome measure for non-verbal children with neurodisability. It is anticipated that this will be used by clinicians to measure the effect of their interventions. What are the practical and clinical implications of this work? Clinicians should reflect on parents' experiences of communication with their child before discussing potential outcomes with them. Gaining insight into the lived experience of communication for non-verbal children and their families will help healthcare professionals to understand which goals are important to them and why. Few studies have specifically asked which communication outcomes are important for non-verbal children with neurodisability. Further exploration is needed to determine which communication outcomes non-verbal children and their families would like to see included in outcome measures used by clinicians.

The Effects of Home Language Use on Spanish Speech Measures in Bilingual Children With Hearing Loss Who Use Cochlear Implants and Their Peers With Normal Hearing.

The purpose of this study was to investigate how the amount of home language use between the primary caregiver and bilingual Spanish- and English-speaking children with hearing loss who use cochlear implants (CIs) versus their bilingual age-matched peers with normal hearing (NH) can impact speech outcomes in the home language. Thirty-four bilingual Spanish- and English-speaking children (17 CI users and 17 with NH) between the ages of 5;3 and 7;9 (years;months) participated in this study. Independent variables were the amount of home language use with the primary caregiver and hearing status, and dependent variables were vowels and consonants correctly produced and occurrence of selected phonological processes. The amount of home language use was ascertained from surveys, and the dependent measures were based on a single-word picture elicitation task. Bilingual children with CIs who are exposed to Spanish for more than 80% of the time via their primary caregiver performed better on Spanish segmental accuracy measures than those who are exposed to Spanish from only 20% to 50% of the time, specifically on vowels (partial η2 = .31) and consonants (partial η2 = .025). Children with NH outperformed children with CIs on all accuracy measures in Spanish. Preliminary results suggest the importance of language exposure through interactions with the primary caregiver for speech development in bilingual children. Future studies should investigate strategies to facilitate home language development in bilingual children with CIs, enabling them to reach their full potential.

The impact of surgical technique and cleft width on the rate of secondary surgery and velopharyngeal function in children with UCLP at 5 years of age

Several factors may influence speech outcome and the rate of secondary palatal surgery in patients with cleft palate. The aim of this study was to evaluate different types of intra-velar veloplasty within an otherwise uniform surgical protocol. The impact of cleft width and the surgeon’s experience on outcome measurements was examined. This cross-sectional study included 62 individuals with unilateral cleft lip and palate born in 2000–2015. Based on the surgical technique used, they were divided into three groups. The cleft width was measured on dental casts. Blinded speech and language pathologists assessed velopharyngeal function with the composite score for velopharyngeal competence (VPC-Sum) for single words. They rated velopharyngeal function on a three-point scale (VPC-R) in sentences. Target consonants in words were phonetically transcribed. The percentage of correct consonants (PCC) was calculated. Surgical technique was not associated with any outcome. Cleft width was associated with the rate of secondary palatal surgery (OR 1.141, 95% CI 1.021–1.275, p = .020) and velopharyngeal insufficiency when using VPC-R (OR 2.700, 95% CI 1.053–6.919, p = .039) but not when using VPC-Sum (OR 1.985, 95% CI.845–4.662, p = .116). PCC was not associated with cleft width and did not differ between surgical techniques. Radical muscle dissection did not exhibit superiority over intra-velar veloplasty reinforced by the palatopharyngeal muscle. Follow-ups at later ages with larger groups will be necessary to evaluate and compare surgical techniques accurately. Cleft width had a greater impact on the rate of secondary surgery and velopharyngeal function than surgical technique, but neither affected the PCC.

Investigating the Impact of Additional Congenital Malformations on Speech Outcomes at age Five in Children with a Cleft Palate.

To determine whether children born with a cleft palate ± lip (CP ± L) and additional congenital differences (ACDs - including 'Congenital malformations and deformations' as coded in ICD-10), are less likely to meet the three national speech outcome standards at age five compared to children with CP ± L and no ACDs. An observational study, utilizing national data from the UK Cleft Registry and Audit NEtwork (CRANE) Database linked to national administrative data of hospital admissions. National Health Service, England. 2191 children (993 female, 1198 male) with CP ± L, born 2006-2012 in England, with complete speech data and consent to data linkage. Perceptual speech analysis utilised the Cleft Audit Protocol for Speech - Augmented (CAPS-A) rating and United Kingdom National Speech Outcome Standards (Speech Standard 1 (SS1), Speech Standard 2a (SS2a) and Speech Standard 3 (SS3)). Of 2191 children, 759 (35%) had at least one ACD. Presence of one ACD did not significantly impact speech outcomes but two or more ACDs reduced the odds of achieving all three speech standards: SS1 aOR 0.602 (CI 0.45-0.82, P = .002), SS2a aOR 0.563 (CI 0.41-0.77, P = .001), SS3 aOR 0.606 (0.43-0.84, P = .003). When exploring ACDs by ICD-10 groupings, congenital malformations of the 'Eye, ear, face and neck', 'Circulatory system', 'Digestive system', 'Musculoskeletal system' and 'Other congenital malformations' reduced a child's odds of achieving the speech standards. ACDs, in the absence of a known syndrome, have a significant impact on speech outcome at age five. Incorporating these factors into risk-adjustment models for service level outcome reporting is recommended.

Speech Outcome Audit for Cleft Lip and Palate Patient Population Correlated With Veau Cleft Type, Surgical Repair Technique, and Patient Age

Objective: The objective of this study is to determine speech outcome differences for specific palate repair techniques and correlate these data with patient age at the time of operation. Methods: A retrospective study was conducted on a cohort of consecutive nonsyndromic patients who underwent cleft lip and/or palate repair at the authors' hospital between 2010 and 2020. Only those patients who participated in at least 4 years of follow-up accompanied by audio-video recording were included. The patient cohort was divided into 2 age groups, between 1 year and 2 years of age versus older than 2 years of age. Standardized perceptual speech evaluations and nasopharyngoscopy were performed by the authors' team to detect the presence of velopharyngeal insufficiency. Results: A total of 481 patients were initially evaluated, and 323 of these patients met all inclusion criteria and were subsequently selected for this study. One hundred seventy-two patients (n = 172) underwent palatal surgery using the Bardach 2-flap palatoplasty technique, 47 patients (n = 47) underwent repair through the von Langenbeck palatoplasty technique, 78 patients (n = 78) underwent repair through Veau-Wardill-Killner palatoplasty technique, and 26 patients (n = 26) underwent repair through double-opposing Z-plasty palatoplasty. The rate of residual velopharyngeal insufficiency was statistically similar among all palatoplasty techniques. A comparison between these two age groups revealed that patients younger than 2 years of age showed higher speech outcome success. Conclusion: High rates of speech success are achieved for patients younger than 2 years of age. Speech outcomes success is maximized by proper technique selection in relation to cleft type.

Impact of Cochlear Implant Electrode Array Design on Post-Op Speech Perception.

Electrode array design may impact hearing outcomes in patients who receive cochlear implants. The goal of this work was to assess differences in post operative speech perception among patients who received cochlear implants of differing designs and lengths. Retrospective chart review. Tertiary Care Hospital. Patients (n = 129) received 1 of 9 electrode arrays, which were categorized by design: Lateral wall electrodes (n = 36) included CI522, CI622 (Cochlear Americas), Flex24, and Flex28 (Med El). Midscala electrodes (n = 16) included HiRes Ultra 3D (Advanced Bionics). Perimodiolar electrodes (n = 77) included CI512, CI532, CI612, and CI632 (Cochlear Americas). Speech perception was evaluated using consonant-nucleus-consonant (CNC) tests and at 3, 6, 12, and 24 months postimplantation. Perimodiolar electrodes showed significantly higher CNC scores compared to lateral wall electrodes at 6 and 24 months. Perimodiolar electrodes also outperformed midscala electrodes at 12 months. An inverse relationship was observed between electrode length and CNC scores noted at 6, 12, and 24 months. Perimodiolar electrode arrays, which tend to be shorter, demonstrated better speech perception outcomes compared to the longer lateral wall and midscala arrays at some timepoints. These findings suggest a potential advantages of perimodiolar electrodes for optimizing hearing outcomes.

A Comparative Effectiveness Study of Speech and Surgical Outcomes: Study Overview.

To provide an overview of the Cleft Outcomes Research NETwork (CORNET) and the CORNET Speech and Surgery study. The study is (1) comparing speech outcomes and fistula rate between two common palate repair techniques, straight-line closure with intra-velar veloplasty (IVVP) and Furlow Double-Opposing Z-palatoplasty (Furlow Z-plasty); (2) summarizing practice variation in the utilization of early intervention speech-language (EI-SL) services; and (3) exploring the association between EI-SL services and speech outcomes. Prospective, longitudinal, observational, comparative effectiveness, multi-center. Twenty sites across the United States. One thousand two hundred forty-seven children with cleft palate with or without cleft lip (CP ± L). Children with submucous cleft palate or bilateral sensorineural severe to profound hearing loss were excluded from participation. Straight-line closure with IVVP or Furlow Z-plasty based on each surgeon's standard clinical protocol. The primary study outcome is perceptual ratings of hypernasality judged from speech samples collected at 3 years of age. Secondary outcomes are fistula rate, measures of speech production, and quality of life. The statistical analyses will include generalized estimating equations with propensity score weighting to address potential confounders. Recruitment was completed in February 2023; 80% of children have been retained to date. Five hundred sixty two children have completed their final 3-year speech assessment. Final study activities will end in early 2025. This study addresses long-standing questions related to the effectiveness of the two most common palatoplasty approaches and describes CORNET which provides an infrastructure that will streamline future studies in all areas of cleft care.

Impact of tongue base mucosectomy on quality-of-life outcomes: systematic review and single-centre experience.

Tongue base mucosectomy (TBM) is a well-established procedure in investigating cervical squamous cell carcinoma of occult primary. However, its risks have not been balanced against its benefits with validated tools. A systematic literature review was conducted for reported complications and quality-of-life outcomes following TBM. The complications and quality-of-life outcomes following TBM at our institution are then reported using objective metrics and validated assessment tools, including Performance Status Scale for Head and Neck Cancer Patients (PSS-HNS), University of Washington Quality-of-life Questionnaire (UW-QOL) and M. D. Anderson Dysphagia Inventory (MDADI). Eighteen studies met the criteria for inclusion in the systematic review. Of these, 9 addressed swallowing outcomes described in text, without using validated assessment tools. No studies reported taste, speech and pain outcomes after TBM. Post-operative bleeding was not consistently reported. 20 patients underwent robotic TBM at our institution between 2017 and 2023. The primary tumour was identified in 50% (10/20) of cases. The median time to commencing soft diet and median time of NG feeding was 0 days. The median return to normalcy of diet score was 95. Median post-treatment UW-QOL pain and swallowing scores were 100 and 70 respectively. The median speech score was 100, saliva 70, and taste 70. The median normalised MDADI scores were: global 80; emotional 67; functional 80 and physical 65. Validated assessment tools better inform patients about treatment options and can help compare post-TBM results across institutions. Our data demonstrates that TBM patients have a functional post-operative swallow, are pain and gastrostomy free, even after adjuvant treatment. Routine post-operative insertion of NG tube is not necessary.

Animal-assisted services for adults with acquired neurogenic communication disorders: A scoping review.

There is increasing interest in the incorporation of animal-assisted services (AAS) in therapy for adults with acquired neurogenic communication disorders. AAS have the potential to enhance speech and language therapy engagement and outcomes. However, a greater understanding of the nature and potential benefits of these interventions is needed. To describe the existing evidence for the incorporation of AAS in therapy with adults with acquired neurogenic communication disorders and to identify areas for future research. A scoping review was conducted and reported in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist extension for scoping reviews (PRISMA-ScR). Seven databases (PubMed, Embase, CINAHL, PsycINFO, Cochrane, Scopus, Web of Science) and grey literature (Google) were searched. Two reviewers independently screened titles, abstracts and full texts against eligibility criteria using Covidence software. The Template for Intervention Description and Replication (TIDieR) checklist guided extraction of intervention data. A total of 17 studies with adults with aphasia, apraxia of speech and cognitive-communication disorders were included. While terminology varied, most interventions met the definition of animal-assisted therapy or animal-assisted activity and used therapy dogs. Across studies, a range of outcomes were targeted, and positive benefits were reported for participant mood, emotions, motivation and satisfaction. There were mixed, but mostly positive, benefits on social behaviour, communication and participation. AAS has been incorporated in therapy for adults with acquired neurogenic communication disorders, predominately with people with dementia. Across studies, communication impairments and AAS interventions were insufficiently or inconsistently described. Improved reporting would assist understanding of the potential benefits of AAS as an adjunct therapy. A quality appraisal of existing studies, and meta-analysis of findings, is needed to draw conclusions about the effectiveness of AAS as a complementary therapy for people with acquired neurogenic communication disorders. What is already known on this subject There is increasing interest and research in AAS as an adjunct to traditional speech and language therapy. Several clinical populations have been shown to benefit from the incorporation of AAS as a complementary therapy approach, including adults with acquired neurogenic communication disorders. To date there has not been a comprehensive review of literature in the area. What this paper adds to the existing knowledge This review aimed to describe what is known about AAS as an adjunct intervention for adults with acquired neurogenic communication disorders. A total of 17 studies were identified, the majority conducted with people living with dementia. Overall, consistent positive benefits of AAS were reported on participant mood, positive emotions, motivation, and satisfaction. There were mixed, but mostly positive, benefits of AAS on social behaviour, including both verbal and non-verbal communication outcomes, and participation. What are the practical and clinical implications of this work? These results suggest a potential therapeutic benefit for the inclusion of AAS into traditional modalities used by speech-language therapists with people with acquired neurogenic communication disorders. However, clinicians should view these findings with caution. Studies were often insufficiently or inconsistently reported, and a quality appraisal and meta-analysis of existing studies would be needed to draw clear conclusions on the effectiveness of AAS as a complementary approach for people with acquired neurogenic communication disorders.

Longitudinal follow-up of hearing, speech, and language skills in 6-year-old children with congenital moderate hearing loss

ObjectivesChildren born with moderate hearing loss present with speech and language outcomes at both ends of the spectrum. To explore reasons for this, the objective of this study was to follow up a group of children born with moderate sensorineural hearing loss at 6 years of age (n=7) by investigating their outcomes in hearing, speech, and language development from time point of hearing aid fitting at 6 months. Another objective was to investigate the relationship between earlier outcomes on precursing variables to the current status in auditory, speech and language development. MethodEarlier data from a project with the same participants of auditory variables, speech, and language development were compared to the current study outcomes at 6 years of age. Children in this study performed standardized tests of phonology (SVANTE), expressive vocabulary (BNT), and speech-in-noise test (Hagerman´s sentences). Parents reported on their child´s functional auditory performance in everyday life (PEACH), and demographics and general development (questionnaire). Etiology and frequency of speech and language-directed intervention from time point of diagnosis to 6 years of age were collected through medical journals. ResultsHearing levels were stable over time in all children but one, who had received bilateral cochlear implants. Performance on speech-in-noise testing varied in aided condition (-0.8 to 8, mean 2.65, SD 3.09) and unaided condition (7.2 dB to 21.2 dB, mean 12.06, SD 4.82). Scores on the PEACH indicated further review in four of the seven children. Mean group score on consonant proficiency had increased from 3 to 6 years of age and were within age norms. Vocabulary scores were below the norms of children with typical hearing. Outcomes on vocabulary measures at 2.5 years years showed strong correlations that were significant to scores on the BNT at 6 years of age (r = 0.87, p = 0.05). Correlations between hours of hearing aid use and vocabulary was not significant at 6 years of age. The frequency of intervention sessions in the first 6 years varied between participants (4 to 55, mean 19.1, SD 17.1). ConclusionDespite homogeneous hearing and other background variables in the participants from birth, large individual variations in speech and language outcomes at 6 years of age were found. Considering the many factors involved that impact the development of children with moderate hearing loss, the results suggest that monitoring early precursors in auditory, speech and language development may be helpful in setting commensurate goals for each child. Detecting additional conditions that may pose challenges in future speech and language as early as possible is important. There is ample room for improvement in terms of increasing the frequency of intervention for children with moderate hearing loss and their families.

A Systematic Review and Meta-analysis Examining Outcomes of Cochlear Implantation in Children With Bilateral Cochlear Nerve Deficiency.

To assess hearing and speech outcomes in pediatric patients with bilateral cochlear nerve deficiency (CND) who underwent cochlear implantation (CI) and to identify factors associated with improved outcomes. PubMed, Embase, Web of Science, and Cochran databases were searched following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that reported hearing and speech outcomes of pediatric patients with bilateral CND who underwent CI were included. Demographics, comorbidities, inner ear abnormalities, CND classification (aplasia or hypoplasia), details of diagnostic workup, and outcomes data were extracted. Outcomes were assessed using the four-level auditory performance level (APL) scale. Meta-analysis, using Cochran-Armitage tests, was performed on patients with individual data to assess factors associated with performance. A total of 314 papers were screened, and 40 papers with 378 total patients met inclusion criteria. A total of 339 patients had patient-level data and were included in the meta-analysis. Of the 339 patients, 19% (n = 63) of patients had no measurable stimulation, 28% (n = 95) had improved detection, 22% (n = 76) achieved closed-set speech perception, and 31% (n = 105) achieved open-set speech perception. Patients with cochlear nerve aplasia (p = 0.016) and syndromes (p < 0.001) had significantly worse APL scores relative to patients with cochlear nerve hypoplasia and patients without syndromes, respectively. While most patients with bilateral CND benefit from CI and almost one-third of patients achieved open-set speech perception, outcomes were heterogenous and one-fifth of patients did not experience measurable benefit from CI.

Clinical Outcomes after Cleft Palate Repair at a Major Referral Hospital in Addis Ababa, Ethiopia

Background: The two most common complications after primary palatoplasty are oronasal fistula and velopharyngeal insufficiency (VPI). To the best of our knowledge, there have been no studies examining postpalatoplasty speech outcomes in Ethiopia. Methods: A hospital-based retrospective cross sectional study design was used. A total of 149 patient records were reviewed, and 103 patients fulfilled all the inclusion criteria. These 103 cleft lip and palate patients who had undergone cleft palate repair at Yekatit 12 Hospital Medical College and who had undergone long-term speech assessment with the speech therapy department from January 2019 to December 2021 were included in this study. The bivariate/multivariate logistic regression was used to compare between different groups of patients, with the level of significance set at a P value of less than 0.05. Results: Moderate and severe hypernasality was seen in 45.7% of patients. Age at time of palatal surgery has significant association with incidence of hypernasality (P = 0.01). The type of cleft, sex of the patient, and type of surgery had no significant association with incidence of hypernasality. Oronasal fistula was seen in 25% of patients, with Pittsburgh type VI being the most common (40%). Conclusions: There is a high rate of VPI and oronasal fistula in this cohort of patients who underwent palatoplasty at Yekatit 12 Hospital. One of the factors for higher complication rate was older age at time of surgery. Therefore, patient education and strengthening the cleft care with training are paramount to ensure better results.
