THIS marks the anniversary of the first case of acoustic tumor operated by myself on the first Tuesday of December 1962. Since that date 20 patients have been operated with cerebellopontine-angle tumors found in 14. At the beginning of this work in 1962 there was only one approach to the internal auditory canal which has not been mentioned yet, the middle fossa approach. The great usefulness of this route is that the internal auditory canal may be exposed without damage to cochlear or vestibular function. This makes possible exploratory procedures in those cases where they might otherwise be avoided because of the concomitant hearing loss with the translabyrinthine approach. This great advantage is best demonstrated by the fact that House, by using the middle fossa approach, has been able to remove a tiny acoustic tumor from the internal auditory canal with preservation of hearing in two patients to date.
