The incidence of secretory otitis media in cases of cleft palate

Distribution and risk factors of cleft lip and palate on patients from a sample of Damascus hospitals - A case-control study

OBJECTIVE

This case-control study was conducted to determine the distribution of cleft lip and/or palate, its association with family history, syndromes and serous otitis media (SOM), and its relation with several risk factors.

METHODS

The case group comprised of 133 children born with cleft lip and/or palate, and the control was 133 non-cleft children born full-term. Data was collected including age, gender, origin and risk factors for cleft lip and palate from patients' files, interviewing supervising doctors, and the patient. Data was then filled out into Excel and underwent statistical analysis using the Goodness of Fit Test and Chi-Square to determine the significance of the results.

RESULTS

Cleft lip and/or palate (CL/P) was slightly higher among males (51.9%). Combined cleft lip and palate (CLP) was the most common presentation (42.1%). Cleft lips (CL) were mostly complete cleft (51,5%) incomplete cleft comprised (41.1%), In the sample 35.4% of the cases were bilateral, 32.3% were right unilateral, 28.3% were left unilateral and 4% were median cleft. Cleft palate (CP) was mostly complete (46.6%) there were incomplete clefts (40%), and the remainder were submucosal (13.4%). Isolated CL and combined CLP were higher in males (51.6%, 62.5% respectively). Both isolated CP and Tessier anomaly were more common in females (64.7% and 58.3% respectively). consanguineous marriages accounted for 36.1% of cases. 21.8% of the sample had a first-degree relative and 24.8% had a second degree relative born with CL/P. There were only 7 cases (0.05%) of syndromic CL/P: Down's (4), Pierre Robin's (2), and Van der Woude Syndrome (1). A relationship was found between CL/P and the risk factors: taking anticonvulsants (without specifying the drug) (p = 0.025, OR = 10.73 C.I. 95%), taking retinoic acid (p-value = 0.049, OR = 4.75 C.I. 95%), not consuming folic acid (p-value = 0.00, OR = 28.23 C.I. 95%), and smoking cigarettes (p-value = 0.046, OR = 2.00 C.I. 95%). There was no relationship with maternal alcohol consumption or maternal diabetes (p-values = 0.652 and 0.210, respectively). SOM was present in 63.2% of patients with CL/P and were mostly isolated CP.

CONCLUSION

CL/P was only slightly higher among males. The most common condition was CLP. There was higher incidence of CL/P among second-degree relatives than first degree. Down's, Pierre Robin's, and Van der Woude Syndromes may be associated with CL/P. Taking anticonvulsants, taking retinoic acid, not consuming folic acid, and smoking cigarettes all have a role in the incidence of CL/P. More than half of the sample had an associated SOM.

Pre-operative and post-operative audiological assessment in cleft lip and palate patients-a prospective study

Purpose

To assess association of audiological defects in cleft lip and palate (CLP) following two stage cheiloplasty and palatoplasty using clinical evaluation and otoscopy and effect of the surgical repair at an interval of one year.

Materials and methods

A pilot research study was performed on sixty CLP patients of 1-6 years of age reporting at Craniofacial & Research Centre, Dharwad, India between October 2016 to October 2018.Subjects were assessed based on history, clinical examination and otoscopy for audiometric defects including Serous otitis media (SOM), retraction pockets, impacted wax pre-palatoplasty and findings were compared with control group. Study group were followed up postoperatively at 1, 3, 6 and 12 months and statistical analysis was carried.

Results

Higher incidence of conductive audiological defects were noted in study group (96.6%) to control group (8.33%). Of the sixty cleft patients subjected to screening otoscopy, 58 subjects had significant findings like serous otitis media(12.07%), retraction pockets(23.14%), impacted wax(62.04%), bulging of tympanic membrane(3.45%) which were clinically unnoticed. Post palatoplasty no changes were noted at 1 and 3 months, however at 6- and 12months significant improvement was noted (55.17%), with three subjects lost to follow up (6.90%) and none presenting with permanent deafness.results.

Conclusion

Cleft anomalies occur in different degrees of severity and configuration with greater incidence of conductive hearing defects of 97%. Positive correlation was noted in cleft palate cases with significant improvement after palatoplasty at an earlier age. However, future long term studies are warranted for long term assessment of Eustachian tube function.conclusion.

Differences in the Tensor Veli Palatini Muscle and Hearing Status in Children With and Without 22q11.2 Deletion Syndrome

PURPOSE

To investigate the dimensions of the tensor veli palatini (TVP) muscle using high image resolution 3-dimensional magnetic resonance imaging (MRI) of the soft palate among children with normal velopharyngeal and craniofacial anatomy and to compare values to individuals with a diagnosis of 22q11.2 deletion syndrome (22q11DS). We also sought to determine whether there is a relationship between hypoplasia of the TVP and severity of middle ear dysfunction and hearing loss.

METHODS

Three-dimensional MRI were used to collect and analyze data obtained across 53 children between 4 and 12 years of age, including 40 children with normal velopharyngeal and craniofacial anatomy and 13 children with a diagnosis of 22q11.2 DS. Tensor veli palatini muscle length, thickness, and volume as well as bihamular distance were compared among participant groups.

RESULTS

A Welch's t-test revealed that the TVP in participants with 22q11DS is significantly shorter (P = .005, 17.3 vs 19.0 mm), thinner (P < .001, 1.1 vs 1.8 mm), and less voluminous (P < .001, 457.5 vs 667.3 mm³) than participants without 22q11DS. Participants with 22q11DS also had a greater (P = .006, 27.7 vs 24.7 mm) bihamular distance than participants without 22q11DS. There was an inverse relationship between TVP abnormalities noted above and the severity of audiologic and otologic histories.

CONCLUSION

The TVP muscle is substantially reduced in volume, length, and thickness in children with 22q11DS. These findings serve as preliminary support for the association of patient hearing and otologic severity and TVP dysmorphology.

FREQUENCY OF OTITIS MEDIA WITH EFFUSION IN CLEFT PALATE CHILDREN

Background: Children with cleft palate oftenly present with otitis media with effusion. The objective of this study was to determine the frequency of otitis media with effusion among cleft palate children. Material & Methods: This cross-sectional study was carried out in the Department of ENT, Pakistan Institute of Medical Sciences, Islamabad, Pakistan from June 2017 to December 2018. Ninety patients were selected through consecutive sampling technique. All children 3-10 years of age with cleft palate were included. Patients with combined cleft palate and cleft lip were excluded. All patients underwent otoscopy and tympanometry. Type B tympanogram was considered as evidence of fluid in the middle ear. Later on patients with only Type B tympanogram underwent myringotomies. Results: Out of 90 (180 ears) patients 61 (67.78%) were males and 29 (32.22%) females. Mean age of the sample was 6.15±2.226 years (3-10, range 7 years). On otoscopic examination, 107/180 (59.45%) ears were suspected to have fluid in the middle ear. Type B tympanogram was detected in 125/180 (69.45%) ears. Only 38/90 (42.20%) patients (76/180 ears), underwent pure tone audiometry. Based on otoscopic, tympanometric and audiometric findings, myringotomies were performed in 125/180 (69.45%) ears. At myringotomy fluid was present in middle ear space of 98/180 (78.4%) ears. Out of total 180 ears the true frequency of otitis media with effusion was 98/180 (54.45%). Conclusions: The frequency of otitis media with effusion in patients with cleft palate is high. Tympanometry is fairly sensitive in diagnosing this condition in these patients.

Clinical Study on Middle Ear Diseases in Children with Orofacial Clefts

Introduction

Orofacial clefts are associated with middle ear diseases, but the magnitude of this problem is not generally well appreciated. The aim of this study was to describe the middle ear findings and audiological profile in children with orofacial clefts.

Materials and methods

Children with orofacial clefts attending plastic surgery and otorhinolaryngology departments of a tertiary hospital over one-year duration were included in this study. Ninety-six children with orofacial clefts were identified. They were categorized age-wise as zero to five years, more than five years to 10 years, and more than 10 years to 15 years. They underwent a detailed ear, nose, and throat examination followed by audiological tests, including brainstem evoked response audiogram (BERA), pure tone audiogram (PTA), and tympanometry.

Results

Among 96 children with orofacial clefts, only 24 children (25%) had symptomatic ear problems, whereas on ear examination, 56 children (58.3%) had abnormal ear findings. Middle ear effusion (MEE) was the most common ear condition, and it was seen in 94 ears (48.9%). Cholesteatoma was noted in six children (3.1%). Out of 73 children in the zero to five age group, 58 children (79.5%) did not have any history of ear problem but 55.5% (81 ears) had features of MEE such as a dull tympanic membrane (TM). In the age group of more than five years to 10 years, only four children (28.5%) were symptomatic. Five children (55.5%) out of nine in the age group of more than 10 years had a symptomatic ear problem of which four children (44.4%) had chronic otitis media squamosal disease. The earlier age groups showed a trend of ear disease being asymptomatic compared to older children. Normal hearing was present in only 40 children (41.7%) and various degrees of hearing loss were seen in 56 children (58.3%). The mean air conduction threshold in the age group zero to five years, more than five years to 10 years, and more than 10 years were 33±8.3 decibels (dB), 25±6.2 dB, and 31.5±14 dB, respectively. Out of 144 ears (72 children) in the asymptomatic group, 67 ears (46.5%) had normal hearing. Seventy-seven ears (53.5%) had some degree of hearing loss. Mean air conduction hearing loss in the asymptomatic group was 29.8±7.3 dB.

Conclusion

This study highlights the higher incidence of middle ear diseases compared to the presenting symptoms in children with orofacial clefts. This stresses on the need for a detailed otological evaluation to identify any middle ear pathology so that timely intervention can be taken.

Differences in the Tensor Veli Palatini Between Adults With and Without Cleft Palate Using High-Resolution 3-Dimensional Magnetic Resonance Imaging

OBJECTIVE

To investigate the dimensions of the tensor veli palatini (TVP) muscle in adults with and without cleft palate.

DESIGN

Prospective study.

PARTICIPANTS

There were a total of 14 adult participants, 8 noncleft and 6 with cleft palate.

METHODS

Analysis and comparison of the TVP muscle and surrounding structures was completed using 3D MRI data and Amira 5.5 Visualization Modeling software. TVP muscle volume, hamular process distance, mucosal thickness, TVP muscle length, and TVP muscle diameter were used for comparison between participant groups based upon previous research methods.

RESULTS

Mann-Whitney U tests revealed a significantly smaller ( U < .001, P = .002) TVP muscle volume in the cleft palate group (median = 536.22 mm³) compared to individuals in the non-cleft palate group (median = 895.19 mm³). The TVP muscle was also significantly shorter ( U = 1.00, P = .003) in the cleft palate group (median = 18.04 mm) versus the non-cleft palate (median = 21.18 mm). No significant differences were noted for the other measured parameters.

CONCLUSION

Significant differences in the TVP muscle volume and length among the noncleft participants found in this study may insights into the reported increased incidence of otitis media with effusion (OME) seen in the cleft population. Results from this study contribute to our understanding of the underlying anatomic differences among individuals with cleft palate.

A quantitative method for defining high-arched palate using the Tcof1(+/-) mutant mouse as a model

The palate functions as the roof of the mouth in mammals, separating the oral and nasal cavities. Its complex embryonic development and assembly poses unique susceptibilities to intrinsic and extrinsic disruptions. Such disruptions may cause failure of the developing palatal shelves to fuse along the midline resulting in a cleft. In other cases the palate may fuse at an arch, resulting in a vaulted oral cavity, termed high-arched palate. There are many models available for studying the pathogenesis of cleft palate but a relative paucity for high-arched palate. One condition exhibiting either cleft palate or high-arched palate is Treacher Collins syndrome, a congenital disorder characterized by numerous craniofacial anomalies. We quantitatively analyzed palatal perturbations in the Tcof1(+/-) mouse model of Treacher Collins syndrome, which phenocopies the condition in humans. We discovered that 46% of Tcof1(+/-) mutant embryos and new born pups exhibit either soft clefts or full clefts. In addition, 17% of Tcof1(+/-) mutants were found to exhibit high-arched palate, defined as two sigma above the corresponding wild-type population mean for height and angular based arch measurements. Furthermore, palatal shelf length and shelf width were decreased in all Tcof1(+/-) mutant embryos and pups compared to controls. Interestingly, these phenotypes were subsequently ameliorated through genetic inhibition of p53. The results of our study therefore provide a simple, reproducible and quantitative method for investigating models of high-arched palate.
