Inner ear anomalies are a rare but important cause of sensorineural hearing loss. Combined external and middle ear anomalies are more common, causing conductive hearing loss and cosmetic deformity. The course of the facial nerve canal is altered in many temporal bone anomalies. Its location is of great importance when surgical therapy is anticipated. Vascular anomalies and bone dysplasias occasionally affect the temporal bone. High resolution CT, using thin sections and edge enhancement techniques, is capable of demonstrating the finer bony details of these temporal bone anomalies.
内耳畸形是感音神经性听力损失的一种罕见但重要的病因。外耳和中耳联合畸形更为常见，可导致传导性听力损失和外观畸形。在许多颞骨畸形中，面神经管的走行发生改变。在预期进行手术治疗时，其位置至关重要。血管畸形和骨发育异常偶尔会影响颞骨。使用薄层扫描和边缘增强技术的高分辨率CT能够显示这些颞骨畸形更细微的骨质细节。
