Overview

The authors describe in detail the surgical technique of dissection of a vestibular schwannoma by translabyrinth approach aimed to preserve facial nerve at the best possible functional condition. The results are evaluated in two comparable groups of patients from the point of view of the size of the tumor and the number of patients – without the use of monitoring (first 43 patients) and with the use of perioperative monitoring (the following 57 subjects from the total of 100 patients). In the group of n.VII monitoring, better functional results have been reached in all aspects from the short-term results as well as long-term outcome. However, the authors do not overestimate the importance of n.VII monitoring, since the monitored patients have been operated on at the time of more advanced surgical experience. The importance of perioperative monitoring of n.VII is considered especially in the improvement of orientation in the operation field and the comfort of the surgeon. In a certain sense the perioperative electroneuronography contributes also to the forecast of food postoperative function of n.VII (House-Brackmann I, II and III), but not for estimation of a bad function (especially House-Brackmann V, VI), when a splitting of the preserved facial nerve, which lacks the perspective of functional recovery.
