Abstract

Computed tomography (CT) and MRI have become an integral part of the evaluation of children with hearing loss. Abnormalities on CT or MRI are found in 20% to 50% of children with sensorineural hearing loss and correlate with the degree of hearing loss. CT and MRI have distinct advantages and disadvantages in imaging the middle and inner ear. The timing of radiographic imaging is an important consideration. This article reviews radiographic abnormalities associated with sensorineural, mixed, and conductive hearing losses in children and offers guidance about the proper utilization of imaging studies.

摘要

计算机断层扫描（CT）和磁共振成像（MRI）已成为评估听力损失儿童的重要组成部分。在20%至50%的感音神经性听力损失儿童中可发现CT或MRI异常，且这些异常与听力损失程度相关。CT和MRI在中耳和内耳成像方面有各自不同的优缺点。影像学检查的时机是一个重要的考虑因素。本文综述了与儿童感音神经性、混合性和传导性听力损失相关的影像学异常，并就影像学检查的合理应用提供指导。
