Serous otitis media as a cause for language delay following cleft palate repair—A case-control study

Background and Objectives: Serous otitis media (SOM), also called otitis media with effusion (OME) or glue ear, is a collection of non-purulent fluid within the middle ear space. Children with cleft palate are more prone to develop this condition. This is caused by impaired eustachian tube function in cleft palate. They may present with hearing loss, delayed speech, and language development or poor social behavior. This is a significant cause of conductive hearing loss in the early speech-forming years of their life. Even after an early surgical repair of palate, speech and language defects are frequently identified during regular postoperative follow-up by speech-language pathologists. When identified, the approach to language delay varies across healthcare systems and includes watchful waiting, providing hearing aids to early otological intervention. The primary objective was to compare the incidence of SOM in children with and without language delay following surgical correction of cleft palate. Materials and Methods: A case-control study involving 63 patients was conducted in a tertiary care hospital with a high-volume cleft lip and palate center from June 2022 to March 2023. Thirty children with language delay were identified and grouped as cases and 33 children without language delay as controls. Tympanogram was conducted after the detailed otoscopic examination. Those with Jerger types B and C were diagnosed with SOM. The incidence of SOM in each group was compared statistically. Results: About 70% of cases and 87.9% of controls had SOM. There is no positive correlation between the incidence of SOM and language delay (P-value > 0.05). Conclusion: SOM cannot be identified as a causal factor for language delay after cleft palate surgery.

Development and Characterization of a Novel Composite Hydrogel Biomaterial for Improved Mucoperiosteal WoundRepair.

Mucoperiosteal wound healing, as it occurs after pediatric cleft palate surgery, can be challenging due to the limitations of current treatments such as tissue flaps secured with sutures and fibrin glue. In this study, we characterized the in vitro performance of a novel composite hydrogel biomaterial designed to be employed as an in situ wound filler and enhance mucoperiosteal wound healing. We evaluated a range of photopolymerizable formulations containing methacrylated gelatin (GelMA), glycol chitosan, and bioglass microparticles. Our aim was to identify one or more formulations with an appropriate balance of properties against a set of functional requirements that we established for this application. To test the formulations against these criteria, we measured photopolymerization kinetics, mechanical properties, degradation rate, in vitro biocompatibility, and ex vivo tissue adhesion. All formulations polymerized in less than 90 s using violet light. In addition, we found that GelMA-based hydrogels were more adhesive to mucoperiosteal tissue than clinical standard fibrin glue. Inclusion of small amounts of bioglass in the formulation increased mechanical compatibility with mucoperiosteal tissue, enhanced cytoconductivity, and promoted cell proliferation. Taken together, our results support the suitability of these photopolymerized composite hydrogels as in situ mucoperiosteal wound fillers. Overall, this study lays the groundwork for investigating the in vivo, pre-clinical effectiveness of these composite hydrogels in improving mucoperiosteal wound healing outcomes.

Causative agent for perioperative anaphylaxis in a child with autism successfully identified using the intradermal test under general anesthesia

BackgroundThe skin-prick and intradermal tests are the main diagnostic methods used to identify the causative agent in patients with suspected perioperative anaphylaxis. Although the intradermal test is more sensitive than the skin-prick test, multiple intradermal injections can be painful for children. Here, we present the case of a child with autism and suspected perioperative anaphylaxis. The causative agent was successfully identified using the intradermal test under general anesthesia.Case presentationAn 8-year-old boy with autism developed anaphylaxis during general anesthesia for the fourth cleft lip and palate surgery. An allergic workout was performed, but both the skin-prick and basophil activation tests for suspected causative agents yielded negative results. The patient was afraid of multiple injections, and an intradermal test was performed under general anesthesia by anesthesiologists and allergists. Piperacillin was confirmed as the causative agent, and subsequent surgery using the same anesthetic agents without piperacillin was uneventful.ConclusionsConcerted efforts should be made to identify the causative agent for diagnosing perioperative anaphylaxis.

Foreign-born 5-year-old children with cleft palate had poorer speech outcomes than their native-born peers.

Speech difficulties are common in children with cleft palate, but research on foreign-born children is limited. This study aimed to compare speech outcomes, surgery and speech intervention in 5-year-old foreign-born and Swedish-born children with cleft palate with or without cleft lip. This retrospective study analysed data from the Swedish cleft lip and palate registry for children born between 2009 and 2016 using Pearson's Chi-squared test and binary logistic regression. Among 160 foreign-born (106 boys, 54 girls) and 847 Swedish-born (479 boys, 368 girls) 5-year-olds, foreign-born children had significantly lower rates of sufficient velopharyngeal competence (77% vs. 86%), age-appropriate consonant production (28% vs. 60%), and speech without non-oral speech errors (70% vs. 86%). Differences remained after adjustment for cleft type, gender and additional diagnosed conditions. After further adjustments for age at completed primary palatal surgery, differences in age-appropriate consonant production and speech without non-oral speech errors remained significant. Foreign-born children underwent completed primary palatal surgery at older ages and received more secondary palatal surgery and speech intervention than Swedish-born peers. Foreign-born children showed poorer speech outcomes than Swedish-born peers, despite more secondary palatal surgery and speech intervention. Age at completed primary palatal surgery could partly explain these differences.

Efficacy of Tranexamic Acid in Reducing Blood Loss in Cleft Palate Surgeries - A Systematic Review

Efficacy of Tranexamic Acid in Reducing Blood Loss in Cleft Palate Surgeries - A Systematic Review

Awake 160-Slice Computed Tomography for Upper Airway Evaluation in 17 Dogs.

This study investigated using a 160-slice multidetector computed tomography (CT) scanner for conscious image acquisition in dogs with upper airway disease, and describes findings in dogs that had previously undergone soft palate surgery. Seventeen client-owned dogs with upper airway disease were retrospectively reviewed, and classified into three groups: group I, "untreated brachycephalic obstructive airway syndrome (BOAS) patients"; group II, "previously treated BOAS patients"; and group III, "patients with respiratory disease other than BOAS". Data included signalment, clinical history, direct laryngoscopy and endoscopy findings, previous surgeries and CT findings. CT scans in group I revealed overlong and thickened soft palates in all dogs, and signs of laryngeal collapse in four dogs. Patients in group II exhibited normal soft palate lengths, while patients in group III displayed various findings such as nasopharyngeal narrowing and tracheal collapse. Upper airway examinations under general anaesthesia confirmed most CT findings. This study demonstrates the feasibility and value of conscious CT scanning for assessing upper airway diseases in dogs, providing valuable diagnostic information while eliminating the need for chemical immobilisation, thus reducing patient stress and cost. These findings offer new insight into upper airway anatomy in awake patients, especially in brachycephalic breeds, and lay a foundation for future research.

Dexmedetomidine as a total intravenous anesthetic in pediatric patients undergoing cleft lip and palate surgery: a case series

BackgroundSurgery for pediatric cleft lip and palate repair often utilizes high-dose opioids and inhaled anesthesia, thereby causing postoperative complications such as desaturation and/or severe agitation after anesthesia. These complications are detrimental to the child and medical personnel and cause tremendous psychologic stress to parents. Our aim is to decrease these complications through dexmedetomidine, an alpha-2 receptor agonist with anxiolytic, sympatholytic, and analgetic properties. Devoid of respiratory depressant effect, it allows patients to maintain effective ventilation and reduce agitation, postoperatively. Its unique anesthetic property may shed light on providing safe anesthesia and gentle emergence to this young, vulnerable population.Case presentationA total of 21 patients of Sundanese ethnicity, aged 3 months to 8 years (9 males and 12 females), underwent cleft lip or cleft palate surgery using total intravenous dexmedetomidine. Anesthesia was induced using sevoflurane, fentanyl, and propofol, and airway was secured. Intravenous dexmedetomidine 1.5 μg/kg was administered within 10 minutes, and a maintenance dose of 1.5 μg/kg/hour was continued as the sole anesthetic maintenance agent thereafter. Hemodynamics and anesthetic depth using Patient State Index (SEDLine™ monitor, Masimo Corporation, Irvine, CA, USA) were monitored carefully throughout the surgical procedure. Dexmedetomidine did not cause any hemodynamic derangements or postoperative complications in any of our patients. We found agitation in 9.5% (2/21) of patients.ConclusionDexmedetomidine can be used as a total intravenous anesthetic agent to maintain anesthesia and provide gentle emergence to infants and young children undergoing cleft lip and palate repair.

The Effects Of Early And Delayed Palatal Repair On Maxillary Growth And Speech Outcome In Unilateral Cleft Lip And Palate Patients: A Systematic Review

Some cleft clinics use a two-stage method to correct the cleft palate, which helps avoid reduced maximum growth after early hard palate surgery and impaired speech development after late soft palate repair.. This study sought to evaluate the effects of early vs late palatoplasty on speech and maximum growth results. The following databases were searched: Cochrane Library, Science Direct, Pubmed, and NCBI. The primary objective of this study was to determine whether unilateral, non-syndromic cleft lip, alveolus, and palate patients who underwent early or late hard palate surgery before or after 18 months of age had an impact on speech and maxillary development. Things like case studies, reviews, editorials, textbooks, and studies conducted on animals weren't included. The following systematic observations consist of eight studies. Most studies had methodological quality that ranged from fair to good. This review discusses the experience of cleft centers using a variety of one and two stage palatoplasty procedures and timing, and shows inconsistent results regarding maximal progression. The seemingly inconsistent results of the studies included in this observation of speech outcomes suggest that there is insufficient evidence to conclude whether one- or two-stage palatoplasty has a significant effect on maximal development for a variety of reasons. The review provides inconclusive evidence on the impact of hard palate repair timing on facial growth and speech outcomes in unilateral cleft lip and palate patients, highlighting the need for further controlled studies.

A single-center prospective study of perioperative anesthetic complications in cleft lip, alveolus, and palate surgeries in a teaching hospital in Lagos, Nigeria

ABSTRACT Background: Cleft lip and/or palate are one of the most common congenital craniofacial anomalies that require surgical management. Patients undergoing primary cleft repair are at increased risk of perioperative anesthetic complications due to their young age and anatomical defects. Aim: This study aimed to present the frequency of perioperative airway-related morbidities in the anesthetic management of cleft lip, alveolus, and palate surgeries. Patients and Methods: This study was conducted at Lagos University Teaching Hospital, Nigeria. Patients undergoing cleft lip, alveolus, or palate repair were prospectively studied from January 2015 to December 2019. Data on patient demography, type of cleft, presence of syndromes and other deformities, and intra- and postoperative complications were collected. Results: A total of 150 patients were included, with a median age of 15.5 months, and 67 (44.7%) of the patients were <12 months old. Most patients were female (56%), and the most common type of cleft was lip, alveolus, and palate (36.6%). Sixteen (10.7%) of the patients had associated syndromes. Notably, intraoperative complications were observed in 5 (3.3%) patients, including laryngospasm and difficult intubation. Postoperative complications were rare, with one case of nasal bleeding. Significant associations between presence of other deformities and syndromes and intraoperative complications were noted (P < 0.05). Conclusion: Patients with orofacial clefts and other deformities tend to be predisposed to anesthetic complications. However, the incidence of anesthetic complications in this study was low (3.3%) probably because the current protocol used in the author’s hospital for cleft surgeries was followed and appropriate.

A Systematic Review of Perioperative Nerve Blocks for Cleft Lip and Palate Surgeries

A Systematic Review of Perioperative Nerve Blocks for Cleft Lip and Palate Surgeries

A retrospective analysis of factors affecting speech production in school-aged children with cleft palate (+- cleft lip)

ObjectiveThe present investigation examined how factors such as cleft type, age of primary palatal surgery, diagnosed syndromes, hearing problems, and malocclusions could predict persistent speech difficulties and the need for speech services in school-aged children with cleft palate. MethodsParticipants included 100 school-aged children with cleft palate. Americleft speech protocol was used to assess the perceptual aspects of speech production. The logistic regression was performed to evaluate the impact of independent variables (IV) on the dependent variables (DV): intelligibility, posterior oral CSCs, audible nasal emission, hypernasality, anterior oral CSCs, and speech therapy required. ResultsSixty-five percent of the children were enrolled in (or had received) speech therapy. The logistic regression model shows a good fit to the data for the need for speech therapy (Hosmer and Lemeshow's χ2(8)=9.647,p=.291). No IVs were found to have a significant impact on the need for speech therapy. A diagnosed syndrome was associated with poorer intelligibility (Pulkstenis-Robinson's χ2(11)=7.120,p=.789). Children with diagnosed syndromes have about six times the odds of a higher hypernasality rating (Odds Ratio = 5.703) than others. The cleft type was significantly associated with audible nasal emission (Fisher’sexactp=.006). At the same time, malocclusion had a significant association with anterior oral CSCs (Fisher’sexactp=.005). ConclusionsAccording to the latest data in the Cleft Registry and Audit Network Annual Report for the UK, the majority of children with cleft palate attain typical speech by age five. However, it is crucial to delve into the factors that may influence the continuation of speech disorders beyond this age. This understanding is vital for formulating intervention strategies aimed at mitigating the long-term effects of speech disorders as individuals grow older.

Clinical Evaluation of 51 Patients with Cleft Lip and/or Palate in Social Work at Syariah Hospital.

The study aims to evaluate the surgical outcomes, including post-operative complications, in patients undergoing cleft lip and palate surgery in social work. The study was conducted on 51 patients in three social work settings, with inclusion criteria of age over 3 months, weight over 10 pounds, and normal chest x-ray results. Patients with syndromic or cardiac abnormalities were excluded from the study. The surgery was performed by a team of oral and maxillofacial surgeons with a minimum of 2 years of surgical experience. The study found that post-operative complications were relatively rare and could be managed well. This study has important implications for improving the quality of healthcare services for patients with cleft lip and palate, as well as increasing public awareness of the importance of proper medical care for this condition.

Palate Shape, Drug-Induced Sleep Endoscopy Findings, and Obstructive Sleep Apnea Pharyngeal Surgery Outcomes.

Pharyngeal surgery is a treatment option for patients with obstructive sleep apnea (OSA) unable to tolerate positive pressure therapy. This study aims to determine the association between palate shape as described by Woodson and pharyngeal surgical outcomes. Exploratory analysis of retrospective cohort. Multicenter. Three blinded reviewers assessed palate shape using drug-induced sleep endoscopy (DISE) videos from a previously-assembled cohort of adults undergoing pharyngeal surgery. Palate shape scores were examined for association with surgical outcomes with univariate and multivariate analyses. Multivariate analyses included adjustment for consensus DISE findings determined previously. Two hundred nine study subjects were included from 13 centers. Age was 53.7 ± 11.5 years, body mass index (BMI) was 30.3 ± 5.0 kg/m2, and 21% were female. In isolated soft palate surgery, greater GenuAP narrowing was associated with lesser odds of surgical response, whereas greater GenuLW narrowing was associated with greater odds of surgical response. These findings largely persisted after adjustment for key DISE findings, age, gender, OSA severity, BMI, and tonsil size. Other palate-shape findings were not clearly associated with surgical outcomes, although some palate-shape findings demonstrated trends towardan association with outcomes (P < .10). Greater GenuAP narrowing and GenuLW narrowing were associated with lesser and greater, respectively, odds of surgical response after isolated soft palate surgery. Palate shape and other palate shape level scores were not clearly associated with surgical outcomes. Larger studies may determine more precisely the association between palate shape and pharyngeal surgery outcomes.

The Maxillary Nerve Block in Cleft Palate Care: A Review of the Literature and Expert's Opinion on the Preferred Technique of Administration.

Although the maxillary nerve block (MNB) provides adequate pain relief in cleft palate surgery, it is not routinely used globally, and reported techniques are heterogeneous. This study aims to describe relevant anatomy and to present the preferred technique of MNB administration based on the current literature and the expert opinion of the authors. First, a survey was sent to 432 registrants of the International Cleft Palate Master Course Amsterdam 2023. Second, MEDLINE (PubMed interface) was searched for relevant literature on maxillary artery (MA) anatomy and MNB administration in pediatric patients. Survey response rate was 18% (n=78). Thirty-five respondents (44.9%) used MNB for cleft palate surgery before the course. A suprazygomatic approach with needle reorientation towards the ipsilateral commissure before incision was most frequently reported, mostly without the use of ultrasound. Ten and 20 articles were included on, respectively, MA anatomy and MNB administration. A 47.5% to 69.4% of the MA's run superficial to the lateral pterygoid muscle and 32% to 52.5% medially. The most frequently described technique for MNB administration is the suprazygomatic approach. Reorientation of the needle towards the anterior aspect of the contralateral tragus appears optimal. Needle reorientation angles do not have to be adjusted for age, unlike needle depth. The preferred anesthetics are either ropivacaine or (levo)bupivacaine, with dexmedetomidine as an adjuvant. Described MNB techniques are heterogeneous throughout the literature and among survey respondents and not routinely used. Further research is required comparing different techniques regarding efficacy and safety.

Cleft Lip and Palate Surgery at a Rural African Hospital: A 13-Year Experience From Western Kenya.

Most studies on the treatment of cleft lip and palate (CLP) in low-income and middle-income countries have reported on the experience of urban centers or surgical mission trips to rural locations. There is a paucity of literature on the experience of local teams providing orofacial cleft surgery in rural Sub-Saharan Africa. This study reports the efficacy and cost-effectiveness of cleft surgery performed by an all-local team in rural Kenya. A retrospective chart review was performed on all patients who received CLP repair at Kapsowar Hospital between 2011 and 2023. Information regarding patient age, sex, cleft etiology, surgical management, and home location was retrieved. For the most recent year of study (2023), the authors performed a financial audit of all costs related to the performance of unilateral cleft lip surgery. Descriptive statistics were performed. The authors identified 381 CLP surgeries performed on 311 patients (197 male, 63.3%). The most common etiology of the cleft was left unilateral (28.3%). The average age of primary lip repair decreased from 46.3 months in 2008 to 2009 to 20.2 months in 2022 to 2023 ( P <0.001). The average age of primary cleft palate repair decreased from 38.0 months in 2008 to 2009 to 25.3 months in 2022 to 2023 ( P <0.001). Patients traveled from 23 districts to receive treatment. Age of treatment was not different when distinguished by sex, county poverty level, or travel time from the hospital. The total costs associated with cleft lip repair was $201.6. Adequately staffed hospitals in rural locations can meaningfully address a regional CLP backlog more cost-effectively than surgical mission trips.

Update on using buccal myomucosal flaps for patients with cleft palate and velopharyngeal insufficiency: primary and secondary interventions.

This review aims to examine the indications and anatomical circumstances for when to optimally incorporate buccal myomucosal flaps (BMFs) into palatal surgical reconstruction. Studies examining outcomes following primary cleft palate repair with incorporation of BMF have demonstrated excellent speech outcomes and low rates of fistula. Furthermore, some reports cite an association of buccal flap use with reduced midface hypoplasia and the need for later orthognathic surgery. When used for secondary speech surgery, BMFs have been shown to lead to speech improvements across multiple outcome measures. Advantages of BMF techniques over conventionally described pharyngeal flap and pharyngoplasty procedures include significant lengthening of the velum, favorable repositioning of the levator muscular sling, and lower rates of obstructive sleep apnea. Although the published data demonstrate excellent outcomes with use of BMFs for primary and secondary palatal surgery, there are limited data to conclude superiority over the traditional, more extensively investigated surgical techniques. The authors of this review agree with the evidence that BMF techniques can be useful in primary palatoplasty for congenitally wide clefts, secondary speech surgery for large velopharyngeal gaps, and/or in individuals with a predisposition for airway obstruction from traditional approaches.

Analysis and Reporting of Randomized Trials in Cleft Palate Surgery: Learning from the Timing of Primary Surgery (TOPS) Trial.

The Timing of Primary Surgery (TOPS) trial was published August 2023 in the New England Journal of Medicine and is a milestone achievement for a study focused on cleft palate. Due to the complexity of outcome reporting in cleft and the rarity of such comparative trials, TOPS presents a useful opportunity to critically review the design, analysis and reporting strategies utilised. This perspective article focused on the inclusion of participants, the choice of the primary outcome measure and the analysis of ordinal data within the trial. Considerations for future comparative studies in cleft care are discussed.

Rhinoplasty for unilateral cleft lip deformity

Cleft nasal deformity is most common sequel after cleft lip and palate surgery. The severity of the nasal deformity is usually decided by initial cleft state, previous operation skill and postoperative care. Secondary cleft rhinoplasty for unilateral cleft patient requires both esthetic and functional results. Understanding the anatomic defect and growth potential after cleft operation help to perform favorable secondary rhinoplasty. Surgical methods for deformed cleft nose are diverse and each methods have pros and cons. Closed or open rhinoplasty with or without cartilage graft and piriform augmentation are the mainstay for cleft rhinoplasty. The purpose of this study was to describe current concepts in secondary rhinoplasty for unilateral cleft lip nasal deformity. Secondary rhinoplasty for cleft patients requires an understanding of the anatomic situation, and the use of cosmetic and functional rhinoplasty techniques for its successful management.

The role of videolaryngoscopy in cleft surgery: A single center comparative study before and during the COVID-19 pandemic

BackgroundCleft lip and palate (CLCP) surgeries necessitate precise airway management, especially in pediatric cases with anatomical variations. The Covid-19 pandemic posed unprecedented challenges to anesthesiology practices that required adaptations to ensure patient safety and minimize viral transmission. Videolaryngoscopy (VL) emerged as a valuable tool in airway management during the pandemic, offering improved intubation success rates and reduced aerosol generation risks. MethodsThis retrospective study compared anesthesiology practices in CLCP surgeries before (2015–2019) and during the Covid-19 (2019–2022) pandemic at a tertiary care center. Patient demographics, anesthesia techniques, intubation difficulty, airway management, and intraoperative and postoperative follow-up were analyzed from anesthesia records. ResultsThis study included 1282 cases. Demographics were similar between periods. During the pandemic, there was a significant decrease in the number of patients under one year old (p < 0.001) and a higher prevalence of micrognathia and comorbidities (p = 0.001 and p = 0.038, respectively). Difficult intubation and intraoperative complication rates decreased during the pandemic, but they were not statistically significant. VL usage during the pandemic contributed to improved extubating success (p < 0.001). ConclusionsVL usage and improved patient outcomes were observed during the pandemic, potentially due to proactive measures and infection control protocols. Decision-making processes for extubation and intensive care unit stay became crucial during the pandemic. Understanding the role of VL and its adaptations during the Covid-19 pandemic is vital for optimizing perioperative care in CLCP surgeries and other procedures requiring airway management. The findings highlight the resilience of healthcare systems and the importance of evidence-based practices under challenging circumstances.

Cleft lip and palate surgery simulator: Open source simulation model

ObjectiveCleft lip and palate is the most common craniofacial birth anomaly and requires surgery in the first year of life. However, craniofacial surgery training opportunities are limited. The aim of this study was to present and evaluate an open-source cleft lip and palate hybrid (casting and three-dimensional (3D) printing) simulation model which can be replicated at low cost to facilitate the teaching and training of cleft surgery anatomy and techniques. DesignThe soft tissue component of the cleft surgery training model was casted using a 3D printed 5-component mold and silicone. The bony structure was designed to simulate the facial anatomy and to hold the silicone soft tissue. SettingTwo groups, one group of trainees and one group of expert surgeons, at University Hospital Basel in Switzerland and Pontifical Catholic University of Chile in Santiago, Chile, tested the cleft lip and palate simulation model. Participants completed a Likert-based face and content validity questionnaire to assess the realism of the model and its usefulness in surgical training. ResultsMore than 70 % of the participants agreed that the model accurately simulated human tissues found in patients with unilateral cleft lip and palate. Over 60 % of the participants also agreed that the model realistically replicated surgical procedures. In addition, 80–90 % of the participants found the model to be a useful and appropriate tool for teaching the anatomy and surgical techniques involved in performing unilateral cleft lip and palate repair. ConclusionThis open-source protocol provides a cost-effective solution for surgeons to introduce the cleft morphology and surgical techniques to trainees on a regular basis. It addresses the current financial barrier that limits access to commercially available models during the early stages of surgeon training prior to specialization in the field.
