Sensorineural hearing loss in children

A variety of pathologic conditions cause sensorineural hearing loss in infants and children. Modern imaging techniques such as high-resolution computed tomography (CT) and magnetic resonance (MR) imaging have made it possible to identify a specific cause of pediatric hearing loss in many cases. A classification system has been developed that groups these abnormalities into three anatomic locations along the cochlear nerve: the labyrinth, the internal auditory canal, and the brain stem and cerebrum. Unenhanced high-resolution CT remains the imaging modality of choice in evaluating most cases of pediatric sensorineural hearing loss. In general, CT is the preferred modality in cases of trauma and nonacute congenital otic capsular dysplasias, whereas contrast material-enhanced MR imaging is preferred in cases of inflammatory and neoplastic disorders. Documented acute hearing loss in an older child or adolescent should also be studied with contrast- enhanced MR imaging. Reliable radiologic evaluation requires accurate clinical information as well as knowledge of normal inner ear anatomy and abnormal imaging findings.
