Labyrinthectomy is an effective surgical procedure for the management of poorly compensated unilateral peripheral vestibular dysfunction in the presence of a nonserviceable hearing. It involves removal of labyrinthine portion of the inner ear and exenteration of the neuroepithelium. In our institution, 8 cases underwent surgical labyrinthectomy from a period of 2013-2018 for various extensive disease manifestations, age ranges from 2 to 48 years. Includes, a child of 2 years age presented with bilateral foul smelling otorrhoea with external auditory canal cartilaginous stenosis, 5 cases of extensive cholesteatoma with labrynthitis and 2 cases of purulent labrynthitis among them 1 were suffering from Tuberculosis and was on Category 1 ATT and other one suffering from extensive granulation at the tympanomastoid area which was inconclusive of the diagnosis even after histopathological examination, so treated as tuberculosis and started on prophylactic antitubercular treatment in addition to surgery. All patients except the child gave past history of giddiness, but at the time of presentation they were not having giddiness or noticeable nystagmus and all had profound unilateral sensorineural hearing loss. Thus all the patients underwent a radical mastoidectomy with total labyrinthectomy and blind sac closure in 2 patients.
迷路切除术是一种有效的外科手术，用于治疗在听力无法使用的情况下单侧外周前庭功能代偿不良。它包括切除内耳的迷路部分并清除神经上皮。在我们机构，2013年至2018年期间有8例患者因各种广泛的疾病表现接受了外科迷路切除术，年龄范围为2至48岁。其中包括一名2岁儿童，表现为双侧外耳道有恶臭耳漏伴外耳道软骨狭窄，5例广泛胆脂瘤伴迷路炎，2例化脓性迷路炎，其中1例患有结核病，正在接受1类抗结核治疗，另一例在鼓室乳突区有广泛肉芽组织，即使经过组织病理学检查诊断仍不明确，因此按结核病治疗，除手术外还开始进行预防性抗结核治疗。除该儿童外，所有患者都有眩晕病史，但在就诊时他们没有眩晕或明显的眼球震颤，并且都有严重的单侧感音神经性听力损失。因此，所有患者均接受了根治性乳突切除术及全迷路切除术，2例患者进行了盲袋封闭术。
