Hearing characterization in oculoauriculovertebral spectrum: A prospective study with 10 patients.

Oculoauriculovertebral spectrum (OAVS), also known as Goldenhar syndrome, is considered a condition associated to failing of embryogenesis involving the first and second branchial arches, leading to structural abnormalities arising from it. The aim of this study is to verify the hearing features presented by patients with OAVS and provide additional information that may contribute to improvement of speech therapy. The sample consisted of 10 individuals diagnosed with OAVS and cared for by the Clinical Genetics Service. All patients underwent objective assessment of auditory function through tonal and vocal audiometry. This evaluation was completed using TOAE and BERA. The patient's age ranged from 1 year and 9 months to 27 years and 4 months. At physical examination it was found that 10 had microtia, 7 preauricular tags, 6 low-set ears, 6 ear canal atresia, and 2 preauricular pits. Among the patients, five presented with abnormal hearing. Three patients had conductive hearing loss ranging from mild to moderate, and two patients had sensorineural hearing loss from mild to profound. Three patients had hearing loss in both ears. Speech-language disorders are common in children with OAVS. Thus, the referral to the audiologist and speech pathologist is indicated as soon as possible. Early recognition and detailed understanding of aspects related to the etiology, clinical features, and outcome of patients with OAVS are essential for their proper management. © 2016 Wiley Periodicals, Inc.
