  • Title: Vestibular nerve section in patients with chronic otitis media.
    Author: McElveen JT, Brackmann DE, Hitselberger WE.
    Journal: Am J Otol; 1987 Nov; 8(6):511-5. PubMed ID: 3434614.
    Abstract:
    Retrolabyrinthine vestibular neurectomy preserves hearing and relieves intractable vertigo emanating from the inner ear. However, this approach must be modified in patients with prior "canal-wall-down" procedures. Traversing an exteriorized mastoid cavity risks bacterial contamination of the subarachnoid space. Three patients seen at the Otologic Medical Group with prior canal-wall-down procedures required vestibular neurectomy for persistent vertigo. Using the retrosigmoid approach, the vestibular nerve was sectioned without sacrificing hearing and without traversing a potentially infected mastoid cavity. It is recommended that this approach be considered in patients with intractable vertigo, serviceable hearing, and exteriorized mastoid cavities.
