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.

Review of Current Techniques of Cleft Palate Repair Concerning Palatal Innervation: A Preliminary Assumption.

To highlight the possible surgical steps that could affect the neural supply of soft palate and velopharyngeal sphincter during Furlow palatoplasty and posteriorly-based myo-mucosal buccal flaps in patients with persistent velopharyngeal insufficiency after primary cleft palate repair. Institution-based retrospective study. Academic Medical Center. Non-syndromic patients with persistent hypernasality (after primary cleft palate repair) who had Furlow palatoplasty or posteriorly-based buccal myo-mucosal flaps and were followed up for at least 60 months after the secondary surgery. All patients were examined using a fiberoptic endoscopy, the movement of components of the velopharyngeal sphincter: soft palate, and lateral pharyngeal walls were traced on the monitor and given a score from 0-4. The pattern of VPS closure was reported whether coronal, circular, or sagittal for each case. Patients' characteristics, auditory perceptual assessment, the severity of hypernasality, intraoperative lengthening of the palate, and operative complications were recorded. At postoperative (at least 60 months) evaluation of the patients statistically non-significant differences were reported when comparing the pre-versus post-operative auditory perceptual assessment following both procedures (P value ≥0.05). A greater tendency towards improvement was noticed with BF but was non-significant. The nerve supply of the palate could be jeopardized by many techniques of primary or secondary repair of the cleft palate leaving behind a deceiving intact but weak poor-functioning palate. All efforts should be made to provide more neural-preservation techniques in primary/secondary repair of the cleft palate. Further wide-scale research is essential to have final clear conclusions.

Posterior Positioning of Levator Veli Palatini with Intact Nasal Layer and Side-by-Side Bilateral Buccinator Flaps: Modified Approach for Palatal Lengthening.

To introduce a modified surgical method using bilateral buccinator flaps with posterior positioning of levator veli palatini muscles to treat velopharyngeal insufficiency. Cross-sectional clinical study. Non-syndromic patients with velopharyngeal insufficiency. We performed a modified surgical method using posterior positioning of levator veli palatini muscles and side-by-side bilateral buccinator flaps. Patients' characteristics, severity of hypernasality, palatal lengthening size, and operative complications were recorded and described. The severity of hypernasality was determined by a speech therapist before and after the operation. A total of 26 non-syndromic patients, with a median age of 8.5 years, were enrolled. All patients presented with severe hypernasality. Following the operation and during the follow-up period, 12 patients showed a complete resolution of hypernasality, while 9, 3, and 2 patients exhibited mild, moderate, and severe hypernasality, respectively. In addition, the mean palatal lengthening was measured to be 25.3 ± 3.5 mm. Overall, three patients experienced partial flap loss in one flap, which was successfully repaired with a secondary intention without the development of a fistula. In five cases, complete closure of the donor sites couldn't be achieved and thus were treated with secondary intention. Additionally, postoperative food restrictions were observed in seven cases but were resolved within one month. No other complications were noted in the remaining patients. This modified palatal lengthening technique results in a significant lengthening of the palate while maintaining favorable speech outcomes. Future randomized clinical trials are warranted to validate our findings.

Comparative Effectiveness of Secondary Furlow and Buccal Myomucosal Flap Lengthening to Treat Velopharyngeal Insufficiency.

Secondary Furlow (Furlow) and buccal myomucosal flaps (BMMF) treat velopharyngeal insufficiency by lengthening the palate and retropositioning the levator veli palatini muscles. The criteria for choosing one operation over the other remain unclear. A single-center retrospective cohort study was conducted. Thirty-two patients with nonsyndromic, repaired cleft palate were included. All patients underwent a Furlow or BMMF. Outcome measures included (1) resolution of hypernasality 12 months postoperatively, (2) degree of improvement of hypernasality severity; and (3) change in velar length, as measured on magnetic resonance imaging scans obtained preoperatively and 12 months postoperatively. All measures were performed by raters blinded to participants' medical and surgical history. Hypernasality was corrected to normal in 80% of the Furlow group and in 56% of the BMMF group. Patients receiving BMMF had more severe hypernasality during preoperative speech evaluation. Both groups had a median decrease of two scalar rating points for severity of hypernasality (P = 0.58). On postoperative magnetic resonance imaging, patients who underwent Furlow had a median increased velar length of 6.9 mm. Patients who received BMMF had a median increased velar length of 7.5 mm. There was no statistically significant difference between groups regarding increase in velar length (P = 0.95). Furlow and BMMF procedures increase velar length with favorable speech outcomes. The same degree of improvement for hypernasality was observed across groups, likely explained by the similar increase in velar length achieved. Anatomic changes in palate length and levator veli palatini retropositioning persist 1 year after surgery.

Speech and Burden of Secondary Surgical Interventions Following One-Stage Repair of Unilateral Cleft Lip and Palate and Alveolar Bone Grafting Performed at Different Timings.

A comprehensive assessment of the treatment outcome in cleft lip and palate involves evaluating speech and the impact of speech-correcting surgical interventions. This retrospective case-control study compared the speech outcomes of 37 boys and 19 girls with unilateral cleft lip and palate (UCLP) who underwent one-stage cleft repair at an average age of 8.1 months and alveolar bone grafting either before or after 6 years of age, with a non-cleft control group at an average age of 10 years. Two experienced speech and language pathologists conducted perceptual speech assessments using a specialized test of 27 sentences designed for Polish-speaking cleft patients. The results revealed that 5.3% had severe hypernasality, 1.8% had severely impaired speech intelligibility, 10.7% exhibited retracted compensatory articulations, and 7.1% displayed facial grimacing. Mild hyponasality was observed in 12.3% of patients, while 16.1% exhibited voice abnormalities. Additionally, 12.5% of patients required orofacial fistula repairs, 3.6% underwent pharyngoplasties, and 28.6% received ear ventilation tube insertions. The study indicates that speech abnormalities in UCLP patients were relatively infrequent and not highly severe, suggesting that the primary UCLP repair method presented effectively reduced the need for further surgical interventions, leading to positive speech outcomes.

Effect of perceptive-auditory training on the classification of speech hypernasality.

To analyze the effect of auditory-perceptual training by inexperienced speech-language pathologists in the classification of hypernasality in individuals with cleft lip and palate and compare their classification of hypernasality individually, with the gold standard evaluation, before and after this training. Three inexperienced speech-language pathologists used a four-point scale to assess 24 high-pressure speech samples from individuals with cleft lip and palate, before and after auditory-perceptual training. The speech samples corresponded to six samples of each degree of hypernasality. The speech-language pathologists received auditory-perceptual training during the assessments. They had access to anchor samples and immediate feedback of correct answers regarding the degree of hypernasality in training. There was no significant difference in the overall percentage of correct answers when comparing before and after the auditory-perceptual training. There was a significant association and agreement of the three evaluators with a gold standard evaluation after training, with an increase in agreement for a single evaluator for absent and mild degrees of hypernasality. The dichotomous analysis of the data showed an increase in the Kappa Index of Agreement of this evaluator. Although there was an increase in the Index of Agreement between evaluators for absent, mild, and severe hypernasality, this increase did not reach statistical significance. The auditory-perceptual training provided did not result in a significant improvement in the hypernasality classification for the inexperienced speech-language pathologists, even though the individual data analysis showed that the training favored one of the evaluators. Further studies involving gradual and more extensive auditory-perceptual training may favor the classification of hypernasality by inexperienced SLPs.

Effectiveness of the Superiorly Based Pharyngeal Flap in Treating Velopharyngeal Insufficiency.

A retrospective cohort study included patients with VPI post cleft palate repair who underwent secondary speech surgery. The criteria were based on clinical symptoms, physical examination, nasometry, and videofluoroscopy/nasoendoscopy findings. Data were analyzed by using SPSS program, version 22.0. A P value less than 0.05 was considered significant. Thirty-five patients were identified. VPI was reduced to 14.3% postoperatively. Before the surgery 25.7% of the patients had severe hypernasality, 68.6% had moderate hypernasality, and 5.7% had mild hypernasality. After the surgery, only 8.6% of the patients still had severe hypernasality, 22.9% had moderate hypernasality, 57.1% had mild hypernasality, and hypernasality became absent in 11.4%. Articulation disorders were present in 91.4% of patients before surgery, and decreased to 71.4% postoperatively. Speech intelligibility improved postoperatively in comparison with preoperative findings. The present study concluded that the superiorly based pharyngeal flap was successful in treating VPI that persisted post cleft palate repair.

How Early Can We Predict the Need for VPI Surgery?

This retrospective study reviewed documentation of children with moderate-to-severe VPI at age 3 years who did not undergo VPI surgery until age 5 years. Based on the national cleft register, 959 patients with syndromic and nonsyndromic CP were treated by the craniofacial team at Helsinki University Hospital, Finland between 2000 and 2014. Eighty-six patients fulfilled the study inclusion criteria. The speech pathologist evaluated velopharyngeal function at age 3, 5, and 8 years. Of the 86 children presenting with moderate-to-severe VPI at age 3 years, 94% still had moderate-to-severe VPI at age 5 years, even though speech therapy was offered to 77%. Of those whose velopharyngeal function improved by age 5 years, function regressed to incompetent over time. Overall, 93% underwent VPI surgery and 82% underwent VPI surgery between ages 5 and 8 years. Only 23% at age 8 years still had moderate-to-severe VPI. Speech therapy alone did not improve VPI speech characteristics. Moderate-to-severe VPI did not improve from 3 to 5 years or improved but subsequently relapsed. This suggests that the decision for VPI surgery can be made for children aged 3 years with moderate-to-severe VPI.

Paediatric velopharyngeal insufficiency following adenotonsillar surgery

ObjectivePaediatric velopharyngeal insufficiency (VPI) is a known but rare complication following adenotonsillar surgery that can have significant adverse effects on the communication as well as psychological well-being of the patient and their family. We sought to assess risk factors, aetiology, assessment and management of these patients through a dedicated multidisciplinary clinic. MethodsRetrospective data collection was performed for patients seen in the Great Ormond Street Hospital for Children multidisciplinary VPI clinic from the 1st of January 2015 until 30th of April 2020. Paediatric patients with previous adenotonsillar surgery and no evidence of cleft palate or speech and language disorder were included in the study. Results29 patients met the inclusion criteria, with 16 having previous adenotonsillectomy and 13 isolated adenoidectomy. In our VPI clinic, patients were seen on average for 4.9 occasions over a 38.3-month period. Clinical assessment was conducted using GOS.SP.ASS ’98 speech assessment tool, speech videofluoroscopy and nasoendoscopy, as per individual needs. The main cause of post-adenoidectomy VPI was identified in 72.5% of the cases. Speech videofluoroscopy was performed in 27 cases. Associated anatomic features identified included deep pharynx (37%), long palate (22.2%) and variable levator position. Severe hypernasality was noted in 3 patients, while in 20 cases moderate or mild hypernasality was found. There were no patients with normal speech. Ten patients were treated with speech therapy alone, whereas surgical intervention was required in seventeen cases. In the population who received treatment and had adequately recorded follow-up, improvement in speech was noted in 86.9%, with 30.4% having oral resonance on last review. Of the patients with severe hypernasality, all improved but had some persistent hyper nasality on last clinic review. ConclusionsWe present our multidisciplinary management of post adenoidectomy VPI. Through the investigations in our dedicated specialist VPI clinic, the cause of VPI was found more frequently than in previous reports in the literature. Intense treatment is usually required with lengthy follow-up and multiple attendances in VPI clinic. Main modalities of management include SLT, surgery and speech prostheses. Most patients’ speech will improve with intervention. We highlight the importance of early recognition, referral and a multi-disciplinary approach in treating this condition. We advise ENT surgeons to ensure patients are adequately aware of this complication given its potential impact.

An Innovative Palatoplasty for Primary Cleft Palate Repair

Summary: Many surgical techniques have been developed to restore function in patients with cleft palate. Despite the development of many surgical techniques for primary cleft palate repair there is no standard procedure that ensures palatal function as that in normal children. Furlow’s and intravelar veloplasty are the most common methods for velar repair in patients with cleft palate; however, some limitations have been described by different authors. The objective of this study was to present an innovative method for primary cleft palate repair that addresses the shortcomings of conventional methods. Since 2017, 88 consecutive patients with nonsyndromic unilateral cleft palate have undergone primary anatomical repair of palatal deformity using this technique. This method combines nasal mucosa Z plasty and muscular overlapping with the use of one hemiuvula for uvular repair (unilateral uvuloplasty). The nasal mucosa Z plasty produces velar lengthening by transposition of nasal mucosa and myomucosal flaps. The unilateral uvuloplasty reduces anatomically the velopharyngeal gap and increases the velar length, thus reducing velopharyngeal distance. This innovative palatoplasty, achieves proper anatomical and functional reconstruction of the repaired palate. Only four patients (4.54%) developed mild or severe hypernasality and one patient (1.13%) had postoperative palatal fistula in this group of patients. This innovative technique results in low rates of nondesirable outcomes, improving limitations of conventional methods. Reduced oral mucosa incisions, limited velar muscle dissection, and preservation of the tensor veli palatini anatomy are some of the benefits of this technique.

Treatment of Cleft Lip and Palate in the Amazon Region in Brazil: Speech Results and Sociodemographic Aspects.

To investigate the speech outcomes in individuals with cleft lip and palate (CLP) from the Amazon region and determine their correlation with sociodemographic factors. Cross-sectional, prospective, single-blind study. Tertiary care institute in Manaus, Amazonas, Brazil. Four hundred twenty individuals with CLP, aged 4 to 57 years. The samples were judged by 3 speech pathologists experienced in the speech assessment of individuals with CLP. Hypernasality was scored using a 4-point scale, being 1 = absent, 2 = mild, 3 = moderate, and 4 = severe, and the active speech symptoms were classified as absent or present. The final score for each speech symptom was reached by consensus among the 3 examiners Descriptive analysis of sociodemographic data included origin, socioeconomic status, type of cleft, surgical technique employed, the age they underwent primary and secondary palatoplasty, and palatal fistula. Absence of hypernasality was observed in 41% of the individuals, 18% had mild, 28% moderate, and 13% severe hypernasality. Active speech symptoms were observed in 57% of the individuals. Significant correlations were found between speech outcomes and the variables such as origin, socioeconomic status, age at primary and secondary palatoplasty, and presence of fistula. Most individuals with repaired CLP from the Amazon region presented speech disorders, characterized by hypernasality and active errors. Patients living outside the state capital, of low socioeconomic level, underwent palatoplasty late and with presence of palatal fistula tended to have the worst speech outcomes.

Analysis of oral-nasal balance after intensive speech therapy combined with speech bulb in speakers with cleft palate and hypernasality

ObjectiveTo evaluate the efficacy of the combination of a speech bulb with an intensive speech therapy program in hypernasal participants with cleft palate. MethodsTwenty hypernasal speakers with cleft palate (12 females and 8 males, median age 28.45 years), who were wearing speech bulbs underwent an intensive speech therapy program of 45 sessions over 3 weeks. Three experienced speech-language pathologists rated the participants’ speech recordings before and after intensive speech therapy, with and without the speech bulb. Nasometric recordings and long-term averaged spectra were also analyzed using repeated-measures ANOVAs. ResultsThe ANOVA of the hypernasality ratings showed significant effects of therapy [F (1,19) = 15.97; p < .001], speech bulb [F(1,190 = 28.54, p < .001] and a therapy –speech bulb interaction effect [F(1.19) = 22.30, p < 0.001]. The most favorable listener ratings of hypernasality were obtained post-therapy when participants were wearing their speech bulbs. Without the speech bulb, intensive speech therapy by itself did not result in a significant improvement. With speech bulb, nasalance scores for high [F (1,19) = 14.07, p < .001] and low pressure [F (1,19) = 14.84, p < .001] sentences were significantly lower post-therapy, providing preliminary evidence that an intensive speech therapy program may enhance the effect of a speech bulb. Before and after comparisons of individual nasalance profiles demonstrated variable improvement in 15 participants, no progress in 2 participants and more severe hypernasality after therapy in 3 participants. Long-term averaged spectra corroborated the findings of the perceptual analysis. Based on a frequency bin from 201 to 300 Hz, there was a significant within-subject effect for with and without speech bulb [F(1, 18) = 4.54, p = .047] as well as for before vs. after session [F (1,18) = 7.14, p = .015]. ConclusionThe speech bulb in combination with intensive speech therapy resulted in improved oral-nasal balance for the majority of participants. More research is needed to investigate long-term outcomes as well as individual factors contributing to therapy success.

Automatic hypernasality grade assessment in cleft palate speech based on the spectral envelope method.

Due to velopharyngeal incompetence, airflow overflows from the oral cavity to the nasal cavity, which results in hypernasality. Hypernasality greatly reduces speech intelligibility and affects the daily communication of patients with cleft palate. Accurate assessment of hypernasality grades can provide assisted diagnosis for speech-language pathologists (SLPs) in clinical settings. Utilizing a support vector machine (SVM), this paper classifies speech recordings into four grades (normal, mild, moderate and severe hypernasality) based on vocal tract characteristics. Linear prediction (LP) analysis is widely used to model the vocal tract. Glottal source information may be included in the LP-based spectrum. The stabilized weighted linear prediction (SWLP) method, which imposes the temporal weights on the closed-phase interval of the glottal cycle, is a more robust approach for modeling the vocal tract. The extended weighted linear prediction (XLP) method weights each lagged speech signal separately, which achieves a finer time scale on the spectral envelope than the SWLP method. Tested speech recordings were collected from 60 subjects with cleft palate and 20 control subjects, and included a total of 4640 Mandarin syllables. The experimental results showed that the spectral envelope of normal speech decreases faster than that of hypernasal speech in the high-frequency part. The experimental results also indicate that the SWLP- and XLP-based methods have smaller correlation coefficients between normal and hypernasal speech than the LP method. Thus, the SWLP and XLP methods have better ability to distinguish hypernasal from normal speech than the LP method. The classification accuracies of the four hypernasality grades using the SWLP and XLP methods range from 83.86% to 97.47%. The selection of the model order and the size of the weight function are also discussed in this paper.

Speech-language therapy students’ auditory-perceptual judgements of simulated concurrent hypernasality and articulation disorders

ABSTRACTAuditory-perceptual judgements are regarded as the standard method for assessing speech disorders. However, the results of auditory-perceptual evaluations and rater reliability can be affected by various factors, such as concurrent problems in multiple speech subsystems. This study investigated the effect of a co-occurring articulation disorder on auditory-perceptual judgements of hypernasality and the effect of co-occurring hypernasality on judgements of an articulation disorder. The speech stimuli were sentences produced by a male speaker who simulated four levels of hypernasality (typical nasality, and mild, moderate, and severe hypernasality) at four levels of disordered articulation (typical articulation, and mild, moderate, and severe articulation disorder). Thirty speech and language therapy students used visual analogue scales to rate the severity of hypernasality and articulation disorder for each speech sample. Results showed that the hypernasality ratings were significantly higher when articulation disorder co-occurred compared to those without. However, there was no significant difference between mild, moderate and severe concurrent articulation disorder on hypernasality ratings. The speech samples with typical articulation and those with severe articulation disorder were rated as more severe in terms of articulation problem when combined with severe hypernasality. However, there was no significant hypernasality effect on articulation ratings for speech with mild or moderate articulation disorder. The present results generally agreed with previous findings regarding the effect of co-occurring speech problems on auditory-perceptual judgements. Clinicians are advised to be cautious of the potential impact. If possible, speech evaluation using instrumental techniques should be used to supplement auditory-perceptual judgements.

Measuring Patient-Reported Health-Related Quality of Life in Velopharyngeal Insufficiency: Reliability and Validity of the Brazilian Portuguese Version of the VELO Instrument.

To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Cross-sectional methodological study. Tertiary craniofacial medical center. Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). All patients with VPI 8+ years old and their parents completed the Brazilian-Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. The VELO instrument was tested for internal consistency, test-retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test-retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (-r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity (r > 0.7; P < .001). The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test-retest) and validity (discriminant, concurrent, criterion, and construct).

Velopharyngeal Closure and Resonance in Children Following Early Cleft Palate Repair: Outcome Measurement.

Introduction Timing of cleft palate repair and the method of speech outcome measurement in children with cleft lip and palate are much debated topics. The associated problems and quality of life in these children depend on the timing of the surgery. Aim The aim of this study was to investigate the velopharyngeal (VP) function and resonance parameters in children following early cleft palate repair. Method A total of 25 Kannada-speaking children with early repaired cleft palate were subjected to speech assessment and videofluoroscopic assessment. Perceptual speech parameters measured were severity of hypernasality and presence of nasal air emission. Videofluoroscopy was interpreted in terms of closure ratios to predict the severity of VP dysfunction. Results The analysis of videofluoroscopic images indicated that 48% of children had complete VP closure and 52% had perceptually normal resonance. A good correlation was found between the closure ratio and hypernasality. Conclusion Understanding the perceptual speech parameters and their structural correlates for outcome measurement will give better evidence for refining the existing treatment protocols. Data on a larger population are warranted for establishing predictors of optimum speech outcome.

Investigation of postoperative hypernasality after superiorly based posterior pharyngeal flap

BackgroundVelopharyngeal insufficiency that accompanies speech resonance and articulation disorders can be managed through several intervention methods such as speech-language therapy, prosthetic aids, and surgery. However, for patients with severe hypernasality, surgical interventions are highly recommended. Among available surgical techniques, the posterior pharyngeal flap is most common.Case presentationTwo adult males with high nasalance scores underwent superiorly based posterior pharyngeal flap surgery, followed by speech testing by an expert speech-language therapist. Nasalance scores and articulation accuracy were assessed up until 1 year after the surgery. Nasalance scores were measured five times using a nasometer, after which the average value was calculated.ConclusionsConsistent declines in hypernasality over time are not easy to explain since the pedicled pharyngeal flap narrowed over time, secondary to cicatrization. However, scar tethering of the soft palate in a posterior direction could reduce the velopharyngeal port size over time. Therefore, long-term follow-up with intensive speech therapy is suggested for patients with severe hypernasality.

Analysis of the effects of pharyngeal flap surgery on reducing hypernasality in patients with velopharyngeal insufficiency

Background and Objectives:Velopharyngeal insufficiency (VPI) occurs in 25 to 43% of patients that undergo cleft palate repair. This disorder has a variety of signs including variations in nasal resonance (hypernasality), misarticulating, turmoil in nasal emissions, and grimacing. VPI can considerably affect social relations and the mental health of patients. Numerous methods have been developed for the treatment of VPI such as speech therapy, continuous positive airway pressure (CPAP), prosthetic treatment, and surgical interventions. The most common method, especially in the past three decades, has been the pharyngeal flap method. The objective of this study was to study the effects of the pharyngeal flap surgical method on the treatment of hypernasality which is a measureable sign of velopharyngeal insufficiency.Methods & Materials:In this cross-sectional study, a total of 112 patients with pharyngeal sphincter insufficiency who aged between 3 and 25 and had visited the otorhinolaryngology clinic of Imam Hospital of Ahvaz were studied from 2008 to 2015. The severity of hypernasality was measured by three speech therapists based on a universal parameter before the superior based pharyngeal flap surgery and 3 to 12 months after the surgery. The significance level for the aforementioned statistical tests was 0.05. Data was also analyzed using SPSS 16.Results:Following the superior based pharyngeal flap surgery, improved hypernasality, mild hypernasaliy, severe hypernasality, and hyponasality were observed in 42%, 6.44%, 6.11% and 8.1% of the patients, respectively. None of the 19-year old or older patients showed improvement of hyponasality and only patients aged between 3 and 6 years showed hyponasality. However, statistical analyses revealed that there was no significant difference between the responses of patients with different ages to treatment with superior based pharyngeal flap surgery (p=671).Conclusion:Results of the present study suggest that 12 months after pharyngeal flap surgery almost 87% of patients experience a complete or relative improvement of hypernasality. This finding complies with the findings of numerous previous studies.

Quality of Speech Following Cleft Palate Surgery in Children

Background: Surgical treatment of cleft palate is accompanied with speech problems. Speech therapy in these children after surgery can improve their speech. In this study, we aimed to evaluate the quality of speaking in operated cleft palate patients and speech therapy effects in a small group of these patients. Methods: In this cross-sectional study, speech quality of 55 children with operated cleft palate was assessed regarding resonance, audible nasal emission, consonant production and speech acceptability. Speech outcomes after therapy were evaluated in 19 patients. Results: Cleft palate types were unilateral cleft and lip palate in 18 cases, bilateral cleft and lip palate in 4 cases, secondary cleft palate type in 30 cases and of mere-soft palate in 3 cases. Thirty-five children were operated during the first year of life and 20 were operated after the first year. More than 55% of patients had normal hypernasality with few cases of severe hypernasality and less than 45% had error in consonant production. Patients operated during first year of life had more speech problems. Speech parameters were improved in 19 patients after speech therapy. Conclusion: In conclusion, children with cleft palate have some degrees of speech disorders after repair surgery than could be improved by the speech therapy. Speech therapy should be considered as one of the main treatment protocols along with repair surgery in children with cleft palate.

A perceptual evaluation of resonance disorders in children with repaired unilateral cleft lip and palate in Hospital UniversitiSains Malaysia

Background: In most literature regarding speech outcomes in children with repaired cleft lip and palate (CLP), exhibited resonance disorders despite having surgical repair. However, the types and severity of the resonance disorders vary from one individual to another. Thus, perceptual evaluation is important to determine the speech outcomes in individuals with repaired cleft lip and palate.Aim: The aim of this cross sectional study was to determine the types and severity of resonance disorders of children with repaired unilateral cleft lip and palate (UCLP) and describe the inter- and intra-rater reliability of perceptual evaluation of resonance disorders using GOS. SP.PASS’98. Four children with repaired UCLP in Hospital USM with ages ranging from 8 years old to 12 years old was included in this study. During data collection, history taking was first conducted, then participants’ speech sample was collected and lastly oral motor examination was conducted.Results: 50% of the speech sample was then duplicated for inter- and intraexaminer reliability investigations. Exact agreement and kappa values were used for reliability measures. Seventy five percent (75%) (3/4) participants exhibited hypernasality as the type of resonance disorder and 25% (1/4) participant had no evidence of hypernasality or any other types of resonance disorder. No other types of resonance disorders such as hyponasality, mixed resonance or cul-de-saq was noted in the participants. The severity of hypernasality ranged from mild to severe in the participants. Inter-rater reliability showed fair to almost perfect agreement and intra-rater reliability revealed almost perfect agreement.Conclusion: The results obtained from this study was more or less similar to our other studies conducted on the speech outcome of individuals with repaired UCLP. Although surgical intervention has been provided to these individuals, it is important that referrals be made to SLPs to evaluate their speech outcomes. This is to determine a proper management for the individual.Bangladesh Journal of Medical Science Vol.17(2) 2018 p.282-289
