近年来内窥镜已被用作耳科及神经耳科学手术操作的辅助手段。通过鼓膜切开术切口进行中耳的诊断性检查可以除外外淋巴瘘管，辨认胆脂瘤以及对听骨链状态进行评价。在慢性中耳病手术中内窥镜可以用于定位较难明视区域的隐藏胆脂瘤，如耳咽管口、上鼓室、鼓室窦及后壁完整的外耳道后区胆脂瘤。在保听为目的之一的听神经瘤手术中，内窥镜被用于检查内听道外侧部分的残余肿瘤。在前庭神经切断术中，内窥镜可用于帮助确认耳蜗前庭神经裂面。本文讨论了硬性内窥镜在上述方面的应用技术及优点、局限性。
In recent years, endoscopes have been used as an adjunct to otology and neurosurgical procedures. A diagnostic examination of the middle ear through an eardulotomy incision allows for the evaluation of the extrahepatic fistula, the identification of cholesteatoma, and the auditory cortex status. Endoscopic surgery can be used to locate hidden cholesteatoma in areas of the lesser apparent ophthalmoscope, such as the eustachian tube orifice, upper tympanic cavity, tympanic sinus, and posterior wall cholesteatoma in the posterior wall of the ear. In acoustic hearing surgery for one of the purposes of acoustic neuroma, the endoscope is used to examine the residual tumor of the lateral part of the inner auditory canal. In vestibular neurotomy, the endoscope can be used to help identify cochlear vestibular schizophrenia. This article discusses the application of rigid endoscope in the above aspects and advantages, limitations.
