Transmastoid labyrinthectomy indications. Technique and early postoperative results.

Persistent labyrinthine symptoms may manifest as unsteadiness veering or frank rotational vertigo. When these symptoms are resistant to medical therapy and are associated with hearing in the involved ear which is not of a serviceable level, then a transmastoid labyrinthectomy may be of value in ridding the individual of this disability. We have found that this operation may be performed expeditiously and safely; and if the entire vestibular epithelium is removed, the results of surgery are effective and predictable.
