[Transtympanic neurectomy of the vestibular and cochlear nerves (author's transl)].

Tympanotomy and a transvestibular approach to the fundus of the internal auditory meatus is described. The surgical technique is modified from that proposed by Alvarez de Cozar and Antoli-Candela in 1970. The surgical anatomy of the operative sites is detailed. The surgical procedure is found indicated in patients in whom preservation of hearing is not considered and vestibular neurectomy required. The described technique provides a simple but efficient and safe alternative to the translabyrinthine approach to the internal auditory meatus for division of the vestibular and cochlear nerves.
