ABSTRACT
This study was carried out in order to clarify the selection criteria of the surgical approaches and validate their efficacy in patients with vestibular schwannoma. The evolution and modification of the transpetrosal approach was evolved into combined approaches to vestibular schwannomas. These approaches have been advocated to reduce the mortality and morbidity as well as to improve the surgical results especially in large acoustic neurinoma. Having been stimulated with the fascinating preliminary surgical results of the suboccipital and combined transpetrosal approaches, we have builded up a decision making policy based on the tumor size and the preoperative hearing status for the surgical approaches to vestibular schwannomas. Between May 1996 and September 1997, 21 patients with vestibular schwannoma including one case of NF II underwent either suboccipital or various transpetrosal approaches. There was no surgical mortality. Gross total removal was achieved in 20 patients(95%). Facial nerve function was preserved in 19(90%) and hearing function in 6(46%) among the 13 patients who underwent hearing preservation surgery. The authors confirmed the validity of various transpetrosal approaches in this study and conclude that our policy on the surgical approaches to vestibular schwannomas is quite reasonable.
