Ear Malformations

In spite of modern diagnostic and surgical techniques, the results of congenital ear malformation surgery are often disappointing. Not only are hearing results less than expected, but also postoperative canal stenosis is a significant problem. This paper reviews the historical development of atresia surgery, the various classification systems, and the management of congenital ear malformations at The Otology Group. The authors' surgical technique is described and the postoperative results of 33 ear operations are discussed. Twenty-two of 33 cases showed some improvement in hearing. Postoperative stenosis occurred in 42% of atresia cases.

Background: Hearing impairment is one of the leading health concerns in the world and various health problems are often found associated in such children. This study was planned to find the nutritional status, health problems and associated disabilities in such children.Methods: A total of 234 children in the age group of 5–18 years with hearing loss, from an educational institution catering to such children in Central Kerala, were studied. Data analysis was done using statistical package for the social sciences (SPSS) software and results interpreted.Results: The present study had 234 children who satisfied the inclusion criteria. More than 75% of the children had underweight. 47% had short stature. Overweight and obesity were present in 9.8% and 2.1% of the children. Nutritional deficiencies like anemia (7.7%) and vitamin A and B complex deficiencies (10.7%) were also observed. The significant health problems found were congenital heart disease 5.3%, prolongation of QTc interval 12.4%, seizure disorder 6%, bronchial asthma 4%, refractive errors 7.3%, strabismus 2%, corneal opacities and blindness 0.8%, psoriasis 0.4%, external ear malformations 3.7% and khyphoscoliosis 1.3%. Behavioral problems (44%), visual impairment (11%), poor scholastic performance (17%), dysgraphia (3%), dyscalculia and motor skill impairment (2.1%) were the common associated disabilities.Conclusions: Significant health problems were observed in these hearing impaired children. The prominent ones being malnutrition, congenital heart diseases, prolongation of QTc interval, seizure disorder, bronchial asthma, refractive errors, external ear malformations, psoriasis, khyphoscoliosis, behavioral problems, poor scholastic performance, dysgraphia, dyscalculia and motor skill impairment.

Objective Therapy of ear malformations has changed considerably the last two decades when new surgical techniques are available. This study aimed to evaluate different approaches to improve hearing and esthetics in ear malformations. Methods All patients who underwent rehabilitation for ear malformations between 1960 and 2007 at a University Hospital were investigated. Patients underwent clinical, audiological and x-ray examinations. Attempts to improve hearing were undertaken by ear canal and middle ear reconstruction, and/or bone anchored hearing aid (BAHA). Attempts to improve esthetics of the external ear were undertaken by autogenous reconstruction (AR) and bone anchored episthesis (BAE). Results There were 211 patients (117 male, 94 female) with ear malformations representing 255 ears. 103 of these were syndromic patients. The degree of ear malformation was generally severe, Meurman stage 3 (external ear) and Altman Creemers stage 2B (middle ear). AR (n=64) was successful to a higher degree in milder malformations (93% for Meurman grade 1, 18% for Meurman grade 3). BAE (n=109) was successful to a high degree independent of Meurman degree (92–100%). A mean of 17 dB closure of air-bone gap was obtained by ear canal and middle ear reconstruction (n=111). A mean of 46 dB closure of air-bone gap for BAHA was obtained (n=106). Conclusions With the high degree of success for BAE, this option is valuable for children where AR has failed. With the high degree of success for BAHA, children can be supplied with BAHA early and middle ear reconstruction postponed until adolescence.

Although the hearing loss of patients with Treacher Collins syndrome is well documented, few studies have reported jointly on their hearing loss and ear pathology. This paper reports on the hearing loss and computerized tomography (CT) assessments of ear malformations in a large pediatric series of patients with Treacher Collins. Of the 29 subjects assessed by the Craniofacial Program between 1986 and 1990, paired audiologic and complete CT assessments were available for 23 subjects. The external ear canal abnormalities were largely symmetric, either bilaterally stenotic or atretic. In most cases, the middle ear cavity was bilaterally hypoplastic and dysmorphic, and ossicles were symmetrically dysmorphic or missing. Inner ear structures were normal in all patients. The majority of patients had a unilateral or bilateral moderate or greater degree of hearing loss and almost half had an asymmetric hearing loss. The hearing loss of all subjects was conductive, except for three whose loss was bilateral mixed. Two types of bilaterally symmetric hearing loss configurations, flat and reverse sloping, were noted. Conductive hearing loss in patients with Treacher Collins is mainly attributable to their middle ear malformations, which are similar for those of patients with malformed or missing ossicles.
