Abstract

Congenital ear or temporal bone malformations are a diagnostic challenge to radiologists and surgeons alike. Newer imaging techniques can detect subtle changes in middle ear and cochlear anatomy. This information is invaluable with increasing use of hearing restoration surgeries and/or cochlear implants in such patients. This article discusses the embryogenesis, classification system, and salient imaging findings of congenital outer, middle ear, and inner ear anomalies in children. Both high-resolution computerized tomography and magnetic resonance imaging scans of the temporal bones are described.

摘要

先天性耳或颞骨畸形对放射科医生和外科医生来说都是一个诊断挑战。较新的成像技术可以检测中耳和耳蜗解剖结构的细微变化。随着在这些患者中越来越多地使用听力恢复手术和/或耳蜗植入物，这些信息是非常宝贵的。本文讨论了儿童先天性外耳、中耳和内耳畸形的胚胎发生、分类系统和显著的影像学发现。本文还描述了高分辨率计算机断层扫描和颞骨磁共振成像扫描。
