Defects in the tegmen tympani can have serious consequences such as intracranial infection and seizures, however, they can be difficult to diagnose due to their subtlety on cross-sectional imaging and the non-specific way in which they can present. Repair of such defects can be undertaken via a middle fossa or transmastoid approach; both, however, usually necessitate a general anaesthetic and, furthermore, middle cranial fossa surgery carries the risk of epilepsy while transmastoid repair can result in the loss of hearing. We present a novel method of repair in a patient who would otherwise have been managed conservatively.
鼓室盖缺损可能会导致严重后果，如颅内感染和癫痫发作，然而，由于其在横断面成像上的细微表现以及可能出现的非特异性方式，它们可能难以诊断。此类缺损的修复可通过中颅窝或经乳突入路进行；然而，这两种方法通常都需要全身麻醉，此外，中颅窝手术有癫痫发作的风险，而经乳突修复可能导致听力丧失。我们介绍了一种针对原本需保守治疗的患者的新型修复方法。
