Labyrinthectomy: Our Experience in a Tertiary Care Centre.

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.
