Imaging of Pediatric Hearing Loss

Abstract

Hearing loss in children is a prevalent disability, affecting 1 in 1000 neonates and up to 11% of school-aged children. Imaging plays a key role in the evaluation of conductive and SNHL with multiple modalities including CT and MR imaging. The purpose of this article is to review the anatomy and pathology resulting in conductive and SNHL through an imaging approach. The pathology of pediatric hearing loss includes multiple causes of both osseous and nonosseous abnormalities, which can be categorized into congenital, infectious/inflammatory, and neoplastic processes. The recognition of complex anatomy and pathology of the ear can place the radiologist in a key position in the diagnosis and overall evaluation of pediatric hearing loss and, ultimately, contribute to the management of the patient.

Imaging of Congenital and Acquired Sensorineural Hearing loss: Peeking through the Oval Window into the Cochlea and Beyond

“…The sensory apparatus in the inner ear converts these sound waves into electrical impulses, which are then transmitted along the cochlear nerve to the brain stem and, subsequently, to the contralateral auditory cortex. 1,2 SNHL is said to be present when the abnormality involves either the sensory (cochlea) or neural structures (cochlear nerve to the auditory cortex) and may be congenital or acquired. 1,3 Congenital SNHL is estimated to affect 1 in every 2000 neonates worldwide.…”

“…У сучасній літературі достатньо докладно описані типова і варіантна анатомія та вади розвитку барабанної порожнини [6,8], а також можливі оперативні підходи в цій ділянці, але тільки в поодиноких роботах можна виявити дані про вікові анатомічні особливості структур барабанної порожнини.…”
