Retrolabyrinthine versus middle fossa vestibular neurectomy.
The authors' experience in treating incapacitating peripheral vertigo using the middle cranial fossa (MCF) and the retrolabyrinthine (RL) approaches is presented. Among 94 operated cases, 56 have been treated using the MCF approach and 38 the RL approach. In 18 of the RL cases, a simple vestibular neurectomy has been associated with different adjunctive techniques (i.e., drainage of the endolymphatic sac, section of the Wrisberg intermediary nerve, and neurovascular decompression of the eight nerve) in an attempt to influence the disease from a pathogenetic viewpoint. The RL approach has demonstrated to be a valid alternative to the MCF approach, since it allows the same results to be obtained in the control of vertigo, with fewer risks to the facial nerve and hearing functions. Moreover, it allows the association, although still in an experimental way, of the simple vestibular neurectomy and the other "pathogenetic" methods mentioned above.
