| Abstract: | Vestibular nerve section, whether by the middle fossa or retrolabyrinthine approach, is effective in relieving intractable vertigo while preserving hearing. However, the potential morbidity and technical difficulty of the middle fossa approach have limited its usefulness. In an attempt to determine if the two approaches produce comparable results, we evaluated 52 patients who underwent retrolabyrinthine vestibular neurectomy between April 1981 and March 1983 at the Otologic Medical Group. We compared their audiometric data and questionnaire responses with published data on patients who had a middle fossa vestibular neurectomy. Although differences between the two procedures do exist, the retrolabyrinthine method, with its 93% success rate in improving or resolving vertigo and its zero incidence of total sensorineural hearing loss, offers the surgeon a strong alternative to the middle fossa approach. |
