A labyrinthectomy is a surgical procedure which destroys both the hearing and vestibular functions of the inner ear. It is performed either by drilling out the bone and removing all of the labyrinth (known as an osseous labyrinthectomy), or by opening up the inner ear and destroying some of the soft tissue within it. There is a 95-98% success rate of ending vertigo attacks with a labyrinthectomy. But deafness also needs to be taken into consideration as this condition destroys the hearing function and a labyrinthectomy will not usually be performed if there is still good hearing in the affected ear.
