High incidence of cleft palate and vomer deformities in patients with Eustachian tube dysfunction. Sci Rep 2022; 12:10121. [PMID: 35710691 PMCID: PMC9203571 DOI: 10.1038/s41598-022-14011-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Accepted: 05/31/2022] [Indexed: 11/09/2022] Open
Abstract
Although the cleft palate is regarded as a contraindication for Eustachian tube ballooning, the presence of submucosal cleft palate may be overlooked while diagnosing Eustachian tube dysfunction. Therefore, we aimed to determine the incidence of the presence of a hard palate bony notch and vomer defect, which indicate the presence of submucosal cleft palate in patients with Eustachian tube dysfunction. In the Eustachian tube dysfunction group (n = 28), 4 patients (14.3%) exhibited a hard palate bony notch and a concurrent vomer defect. Three of them exhibited the presence of occult submucosal cleft palate, which had not been diagnosed previously. None of the control group (n = 39) showed any of these findings. The hard palate length of patients in the Eustachian tube dysfunction group was significantly lesser than that of those in the control group (34.2 ± 5.6 mm vs. 37.2 ± 2.1 mm, P = 0.016). Patients with Eustachian tube dysfunction have a high incidence of submucosal cleft palate and its occult variant, which are challenging to diagnose without any preexisting suspicion. Clinicians should evaluate the hard palate and vomer to exclude the presence of occult submucosal cleft palate while diagnosing Eustachian tube dysfunction.

Abstract
Objective Cleft palates are one of the most common congenital malformations. Because of the loss of Eustachian tube function, middle-ear ventilation is reduced. The aim of this study was to determine if middle-ear effusions were present at birth or at the three-month audiological evaluation. Method A total of 53 children with a cleft palate were included. Data review included the results of newborn hearing screening, microscopic findings, a tympanometry, a free field audiometry and intra-operative findings. Results A total of 58.4 per cent of patients had a median, 26.4 per cent had a bilateral, 11.3 per cent had a unilateral and 3.8 per cent had a limited soft palate cleft. Newborn hearing screening showed a pass in 83.1 per cent of newborns bilaterally. The first ear microscopy showed a bilateral middle-ear effusion in 90.6 per cent of cases. During cleft surgery, bilateral paracentesis was performed in all cases, and in 90.6 per cent middle-ear effusion was sucked out. Conclusion The majority of children with a cleft palate do not present with middle-ear effusion at birth. It develops within several days or weeks of life.

Abstract
PURPOSE The aim of this study was to devise a grassroots-level strategy for identification and management of middle ear disorders in a community-based program for individuals with cleft lip and palate in 2 rural districts in the state of Tamil Nadu in South India. METHOD Community workers underwent training to conduct video otoscopy using the ENTraview device. Community workers conducted video otoscopy on 160 individuals with cleft lip and palate between 3 and 35 years old in the community. Middle ear conditions were identified using store-and-forward telepractice. Diagnostic telehearing evaluation was conducted using synchronous pure tone audiometry and tympanometry for those who were identified with tympanic membrane (TM) and/or middle ear diseases (MEDs). A review of data collected over a 13-month period was carried out to assess coverage and follow-up intervention rates. RESULTS The program was successful in achieving 80% coverage for identification of TM and MEDs within 13 months of program implementation. TM and/or MEDs were identified in 26% (82/320 ears) of those who underwent video otoscopy. Telehearing evaluations were completed on 42 ears of individuals with TM and/or MEDs; 52% (22/42 ears) of these individuals had a minimal, mild, or moderate degree of hearing loss. Regarding follow-up for intervention, 78% qualified for surgical intervention, and 31% qualified for medication. CONCLUSIONS This grassroots-level telemedicine approach was successful in achieving better coverage, and store-and-forward telepractice helped in providing remote diagnosis and recommendation by otolaryngologists to all individuals with TM/MEDs in the rural community. The follow-up for otological intervention significantly improved from that achieved in the previous years.

Abstract
Eustachian tube dysfuntion intends to describe a variety of signs, symptoms, and physical findings that result from the impairment of ET function. A large variety of methods have been employed to assess ET function in the literature. Due to the lack of high level evidence, it is difficult to draw conclusions on the effectiveness of medical and surgical treatments. There are various medical and surgical interventions available for chronic obstructive ET dysfunction including balloon Eustachian tuboplasty (BET) and laser or microdebrider tuboplasty. Consensus on diagnostic criteria for ETD is required to define inclusion criteria of future trials. There is however emerging work with reassuring, but preliminary, results that suggest evidence for safety in the surgical management of ETD. Like many newly introduced techniques the current data remains limited to non-controlled case-series, with heterogeneous data collection methods and lacking substantial long-term outcomes. Nevertheless, short-term data provide favorable results. Current treatment options comprising BET and patulous ET surgery may be offered as a treatment possibility to selected patients.

Abstract
Objectives: The Pierre Robin triad (PRT) consists of micrognathia-retrognathia, glossoptosis, and an oval or cleft palate. The goal of this study was to identify patterns of similarity to and differences from the two previous temporal bone studies of the PRT. Methods: Seven children with the PRT (ages, 45 minutes to 2 years; gestational ages, 41 to 43 weeks) were studied. Thirteen temporal bones were decalcified, sectioned at a thickness of 20 μm, and studied by light microscopy. Results: Our study demonstrated multiple architectural anomalies involving the entire ear, including abnormal auricles, and anomalies of the ossicles, including abnormal stapes footplates (6/13). All children showed signs of middle ear infection (12/13). Anomalies of the inner ear included aplasia of the lateral semicircular canals (5/13), a large vestibular aqueduct (2/13), and unusually large otoconia (1/13). In the mastoid process there were islands of cartilage in the expected position of Reichert's cartilage (9/13) and dehiscence of the fallopian canal (11/13). Loss of cochlear hair cells was seen in children who had antemortem hypoxia. Conclusions: Although the PRT is caused by various genes, most anomalies can be traced to the development of the first and second branchial arches.

Abstract
BACKGROUND Cleft lip and palate are among the most common congenital malformations, with an incidence of around 1 in 700. Cleft palate (CP) results in impaired Eustachian tube function, and 90% of children with CP have otitis media with effusion (OME) histories. There are several approaches to management, including watchful waiting, the provision of hearing aids (HAs) and the insertion of ventilation tubes (VTs). However, the evidence underpinning these strategies is unclear and there is a need to determine which treatment is the most appropriate. OBJECTIVES To identify the optimum study design, increase understanding of the impact of OME, determine the value of future research and develop a core outcome set (COS) for use in future studies. DESIGN The management of Otitis Media with Effusion in children with cleft palate (mOMEnt) study had four key components: (i) a survey evaluation of current clinical practice in each cleft centre; (ii) economic modelling and value of information (VOI) analysis to determine if the extent of existing decision uncertainty justifies the cost of further research; (iii) qualitative research to capture patient and parent opinion regarding willingness to participate in a trial and important outcomes; and (iv) the development of a COS for use in future effectiveness trials of OME in children with CP. SETTING The survey was carried out by e-mail with cleft centres. The qualitative research interviews took place in patients' homes. The COS was developed with health professionals and parents using a web-based Delphi exercise and a consensus meeting. PARTICIPANTS Clinicians working in the UK cleft centres, and parents and patients affected by CP and identified through two cleft clinics in the UK, or through the Cleft Lip and Palate Association. RESULTS The clinician survey revealed that care was predominantly delivered via a 'hub-and-spoke' model; there was some uncertainty about treatment strategies; it is not current practice to insert VTs at the time of palate repair; centres were in a position to take part in a future study; and the response rate to the survey was not good, representing a potential concern about future co-operation. A COS reflecting the opinions of clinicians and parents was developed, which included nine core outcomes important to both health-care professionals and parents. The qualitative research suggested that a trial would have a 25% recruitment rate, and although hearing was a key outcome, this was likely to be due to its psychosocial consequences. The VOI analysis suggested that the current uncertainty justified the costs of future research. CONCLUSIONS There exists significant uncertainty regarding the best management strategy for persistent OME in children with clefts, reflecting a lack of high-quality evidence regarding the effectiveness of individual treatments. It is feasible, cost-effective and of significance to clinicians and parents to undertake a trial examining the effectiveness of VTs and HAs for children with CP. However, in view of concerns about recruitment rate and engagement with the clinicians, we recommend that a trial with an internal pilot is considered. FUNDING The National Institute for Health Research Health Technology Assessment programme. This study was part-funded by the Healing Foundation supported by the Vocational Training Charitable Trust who funded trial staff including the study co-ordinator, information systems developer, study statistician, administrator and supervisory staff.

The Importance of Integration of Stakeholder Views in Core Outcome Set Development: Otitis Media with Effusion in Children with Cleft Palate. PLoS One 2015; 10:e0129514.

Abstract
Background Approximately 75% of children with cleft palate (CP) have Otitis Media with Effusion (OME) histories. Evidence for the effective management of OME in these children is lacking. The inconsistency in outcome measurement in previous studies has led to a call for the development of a Core Outcome Set (COS). Despite the increase in the number of published COS, involvement of patients in the COS development process, and methods to integrate the views of patients and health professionals, to date have been limited. Methods and Findings A list of outcomes measured in previous research was identified through reviewing the literature. Opinion on the importance of each of these outcomes was then sought from key stakeholders: Ear, Nose and Throat (ENT) surgeons, audiologists, cleft surgeons, speech and language therapists, specialist cleft nurses, psychologists, parents and children. The opinion of health professionals was sought in a three round Delphi survey where participants were asked to score each outcome using a bespoke online system. Parents and children were also asked to score outcomes in a survey and provided an in-depth insight into having OME through semi-structured interviews. The results of the Delphi survey, interviews and parent/patient survey were brought together in a final consensus meeting with representation from all stakeholders. A final set of eleven outcomes reached the definition of “consensus in” to form the recommended COS: hearing; chronic otitis media (COM); OME; receptive language skills; speech development; psycho social development; acute otitis media (AOM); cholesteatoma; side effects of treatment; listening skills; otalgia. Conclusions We have produced a recommendation about the outcomes that should be measured, as a minimum, in studies of the management of OME in children with CP. The development process included input from key stakeholders and used novel methodology to integrate the opinion of healthcare professionals, parents and children.

Systematic review of the limited evidence base for treatments of Eustachian tube dysfunction: a health technology assessment. Clin Otolaryngol 2014; 39:6-21.

Abstract
BACKGROUND The Health Technology Assessment programme commissioned a wide-ranging review of treatments for adult Eustachian tube dysfunction. Treatments range from advice and observation and pharmacological treatments to surgical options. OBJECTIVE (i) To assess the evidence for interventions for adults with a clinical diagnosis of Eustachian tube dysfunction and (ii) to identify priorities for future research. TYPE OF REVIEW Systematic review (PROSPERO registration CRD42012003035) adhering to PRISMA guidance. SEARCH An extensive search of 15 databases including MEDLINE, EMBASE and CENTRAL (up to October 2012). EVALUATION METHOD Controlled and uncontrolled studies of interventions for adult Eustachian tube dysfunction were included. Because of insufficient data, the protocol was amended to also include controlled studies with mixed adult/child populations. Risk of bias was assessed. Narrative synthesis was employed due to high clinical heterogeneity. RESULTS Interventions assessed were pharmacological treatments [two randomised controlled trials (RCTs), one controlled non-randomised trial (CCT), 159 patients]; mechanical pressure equalisation devices (one randomised controlled trial, one CCT, 48 patients); and surgery, including laser tuboplasty (seven case series, 192 patients), balloon dilatation (three case series, 103 patients), myringotomy without grommet insertion (two case series, 121 patients), transtubal steroids (one case series, 11 patients) and laser coagulation (one retrospective controlled study, 40 patients). All studies had high risk of bias except two pharmacological trials; one had low risk and one unclear risk. No evidence was found for many treatments. The single low risk of bias RCT (n = 91; 67% adults) showed no effect of nasal steroids and favoured placebo for improved middle ear function (RR 1.20, 95% CI 0.91-1.58) and symptoms (P = 0.07). Other studies showed improvements in middle ear function for mechanical devices, antihistamine/ephedrine and nasal decongestant, but they had significant methodological weaknesses including insufficient length of follow-up. None of the surgical studies were adequately controlled, and many reported high levels of co-intervention. Therefore, observed benefits for tuboplasty and balloon dilatation in symptoms, middle ear function or hearing could not be reliably attributed to the interventions assessed. There was variability in definitions of the condition. CONCLUSION Eustachian tube dysfunction is a poorly defined condition. Due to the limited and poor-quality evidence, it is inappropriate to make conclusions on the effectiveness of any intervention; the evidence base is insufficient to guide recommendations for a trial of any particular intervention. Consensus on diagnostic criteria for Eustachian tube dysfunction is required to inform inclusion criteria of future trials.

Acquired middle ear cholesteatoma in children with cleft palate: experience from 18 surgical cases. Int J Pediatr Otorhinolaryngol 2014; 78:918-22. [PMID: 24690221 DOI: 10.1016/j.ijporl.2014.03.007] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2013] [Revised: 03/05/2014] [Accepted: 03/06/2014] [Indexed: 11/29/2022]
Abstract
OBJECTIVES To review an institutional experience with the surgical management of middle ear cholesteatoma in children with cleft palate. MATERIALS AND METHODS We analyzed retrospectively 18 children diagnosed with cleft palate who underwent surgery for acquired middle ear cholesteatoma between 2000 and 2007. The following data were recorded: age, sex, history of ventilation tube insertion, status of the contralateral ear, cholesteatoma location and extension, and surgical technique involved. Cholesteatoma recidivism, stable mastoid cavity and hearing levels were the main outcomes measured. RESULTS Follow-up ranged from 5 to 12 years (mean 8 years). Twelve children underwent planned staged canal wall up mastoidectomy: a residual cholesteatoma was found and removed during the second-look procedure in 2 ears (16.6%); two children (16.6%) showed a recurrent cholesteatoma and required conversion to canal wall down mastoidectomy. A modified Bondy technique was chosen in two children with an epitympanic cholesteatoma with an intact tympano-ossicular system, while in the remaining four subjects a canal wall down mastoidectomy was performed because of an irreparable erosion of the postero-superior canal wall: no cases of recurrent cholesteatoma were observed in these 6 children; revision mastoidectomy was needed in one patient for cavity granulation. A postoperative air-bone gap result of 0-20dB was achieved in 11 children (61.1%); in 5 cases (27.7%) postoperative air-bone gap was between 21 and 30dB, while in 2 (11.1%) was >30dB. Bone conduction thresholds remained unaffected in all cases. CONCLUSIONS Our results indicate that most cleft palate children with cholesteatoma can be managed with a canal wall up mastoidectomy with low complication rates. In extensive disease with large erosion of the canal wall as well in presence of a retraction pocket in the contralateral ear, a canal wall down mastoidectomy should be considered. In epitympanic cholesteatomas with an intact tympano-ossicular system and mesotympanum free of disease, the modified Bondy procedure is an effective surgical option. As in the general pediatric population, improvement or preservation of hearing can be obtained in most patients.

Abstract
OBJECTIVES The objectives of this study were to determine the incidence of acquired cholesteatoma in children with congenital cleft palate, and to determine the impact of various cleft palate types (cleft lip and palate, cleft palate alone, submucous cleft palate) on the development of acquired cholesteatoma. MATERIALS AND METHODS This is a retrospective cohort study spanning a 25-year period from 1981 to 2005. The Cleft Palate Registry at the Hospital for Sick Children in Toronto, Canada was cross-referenced with the hospital's surgical pathology database to identify all children with cleft palate and acquired cholesteatoma. Accuracy and completeness of the datasets were confirmed by comparison with hospital records and other databases. RESULTS There were 2737 children who underwent palatoplasty over the study period, and 44 of these children developed an acquired cholesteatoma. Adjusting for censored data by Kaplan Meier analysis, the incidence of cholesteatoma was 2.2% between the ages 5 and 18 years, or 0.2% per year. Acquired cholesteatoma was 3 times more common in cleft lip and palate than cleft palate alone (p=0.002, Kaplan Meier Log-rank survival analysis). CONCLUSIONS The rate of acquired cholesteatoma in children with cleft palate is approximately 200 times the baseline rate. Children, especially teenagers, with cleft lip and palate appear to be at significantly higher risk for acquired cholesteatoma than children with cleft palate alone.

MOMENT--Management of Otitis Media with Effusion in Cleft Palate: protocol for a systematic review of the literature and identification of a core outcome set using a Delphi survey. Trials 2013; 14:70.

Abstract
Background Cleft palate (CP) has an incidence of approximately 1 in 700. Children with CP are also susceptible to otitis media with effusion (OME), with approximately 90% experiencing nontrivial OME. There are several approaches to the management of OME in children with CP. The Management of Otitis Media with Effusion in Children with Cleft Palate (MOMENT) study is a feasibility study that includes the development of a core outcome set for use in future trials of the management of OME in children with CP. Methods/Design The MOMENT study will include a systematic review of the literature to identify a list of outcomes that have previously been reported. This list of outcomes will be used in a Delphi study with cleft clinicians. The Delphi study is anticipated to include three rounds. The first round will ask clinicians to score the outcome list and to add any outcomes they think are relevant. The second round involves presentation of scores according to stakeholder group and the opportunity for participants to rescore outcomes. To ensure that the opinion of parents and children are sought, qualitative interviews will be completed with a purposive sample in parallel. In the final round of the Delphi process, participants will be shown the distribution of scores, for each outcome, for all stakeholder groups separately as well as a summary of the results concerning outcomes from the qualitative interviews with parents. A final consensus meeting will be held with all stakeholders, including parents and children, to review outcomes. Discussion A core outcome set represents the minimum that should be measured in a clinical trial for a particular condition. The MOMENT study will aim to identify a core outcome set that can be used in future trials of the management of OME, improving the consistency of research in this clinical area.

Abstract
OBJECTIVE Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age. DESIGN Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair. SETTING Centralized, tertiary care craniofacial treatment center. PATIENTS A total of 673 infants with unilateral cleft lip and palate. INTERVENTIONS Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed. MAIN OUTCOME MEASURES Hearing and otoscopic findings at 5 to 6 years old. RESULTS There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio = 5.1, 95% confidence interval = 1.44 to 18.11, p = .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations. CONCLUSIONS Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation.

Abstract
Cholesteatoma is a non-neoplastic, keratinising lesion which has two forms: congenital and acquired. Congenital cholesteatoma develops behind a normal, intact tympanic membrane, whilst acquired cholesteatoma is associated with a defect in the tympanic membrane. The pathological substrate of cholesteatoma is keratinising stratified squamous epithelium, but the origin of this epidermal tissue in the middle ear is controversial. Here, we review the most relevant and recent evidence for the principal aetiopathogenic theories of both forms of cholesteatoma, in the light of recent otopathological findings. Congenital cholesteatoma is most plausibly explained by the persistence of fetal epidermoid formation. Conclusive 'proof' awaits the unambiguous demonstration of the metamorphosis of an epidermoid nidus into a lesion in vivo. Acquired cholesteatoma may develop by various mechanisms: immigration, basal hyperplasia, retraction pocket and/or trauma (iatrogenic or non-iatrogenic). However, squamous metaplasia of the normal cuboidal epithelium of the middle ear is a highly unlikely explanation. Chronic inflammation seems to play a fundamental role in multiple aetiopathogenic mechanisms of acquired cholesteatoma. Therefore early treatment of inflammatory conditions might reduce their sequelae, perhaps by preventing the development of hyperplastic papillary protrusions. Continued otopathological, cellular and molecular research would enhance our limited understanding of cholesteatoma and may lead to new therapeutic strategies for this erosive disease, which often defies surgical treatment.

Abstract
Eustachian tube dysfunction has been linked to causing middle ear pathology. One of the sequelae seen is tympanic membrane retraction. Concern occurs when this physiological state becomes chronic, leading to adhesive otitis media followed by debris collection and fulminate cholesteatoma. This chapter explores the role the eustachian tube plays in regulating middle ear and mastoid aeration, the causes of eustachian tube dysfunction, and the treatment of this disorder.

Abstract
The Eustachian tube regulates the homeostasis of the middle ear. Problems with its function are predominantly found in childhood. As a consequence, otitis and hearing impairment occur. The most important muscle is the tensor tympani muscle. The complexity of the functional anatomy and physiology are reasons why no function test alone is capable of fulfilling all diagnostic needs. The predictive value of the various Eustachian tube function tests for the outcome of a tympanoplasty is not yet clear. An overview of clinically and scientifically relevant tests for the Eustachian tube function is provided.

Abstract
Medical records of eight dogs and one cat with congenital palatine defects were reviewed retrospectively. Five of the dogs had nasal discharge and seven had radiographic signs of middle ear disease, but no clinical signs of ear disease were identified in any of the dogs, nor were any reported by their owners during a one- to five-year follow-up period. One dog had an ipsilateral impairment of hearing detected by brainstem auditory evoked responses. The cat had clinical and radiographic signs of middle ear disease. These findings suggest that, as in humans, congenital palatine defects in dogs and cats may predispose to middle ear disease. Any associated deafness could cause problems for working dogs.
