Abstract:
The result of a series of thirteen translabyrinthine removals of acoustic neurinomas are reported. From 1990 March to 1993 May, thirteen patients with acoustic neuromas underwent translabyrinthine removal at Seoul National University Hospital with cooperation of Department of Neurosurgery and Otolaryngology. In four patients with the medium-sized(11-20 mm) tumors, complete removal with preservation of the facial nerve was possible. In nine patients with the large(21-40 mm) tumors, complete removal of the tumor was possible in seven. Preservation of the facial nerve was possible in all but one, whose facial nerve was incidentally transected at the distal intracanalicular portion and was anastomosed end-to-endly. In one, postoperative leakage of cerebrospinal fluid required reoperation. The results of translabyrinthine approaches were compared with those of suboccipital approaches performed during the same period. In medium-sized or large acoustic tumors, translabyrinthine approach was comparable with suboccipital approach in the rate of total tumors removal, preservation of the facial nerves, and complication.
