ALTHOUGH consideration of the causes of mortality and morbidity in acoustic neuroma surgery is of primary importance in any attempt to improve the therapy of the tumor, it may also be important in the total analysis of such surgery to consider the quality of the results in the presumably "cured" patients who have had total tumor removal. Any new procedure should hopefully decrease the morbidity or mortality or both from previous surgical approaches to the problem, thereby improving both the quality or quantity or both of survival. We were interested in assessing the long-term effects of acoustic neuroma removal on overall health and employability but subjects operated upon via the translabyrinthine approach also offered a unique opportunity to study the long-term effects of unilateral labyrinthectomy and vestibular nerve section as they had had a relatively "neat" extirpation of these structures without manipulation of the brain stem or cerebullum.
