Abstract
Objective To evaluate the treatment choice for small acoustic neuroma with respect to facial nerve preservation.Methods A series of 43 patients with unilateral acoustic neuroma less than 3 cm in diameter were analyzed.All patients were treated by retrosigmoid approach.Pre-and post-operative monitoring of the facial nerve function was performed.Results The serviceable facial nerve function(House-Brackmann Grade 1-3) was 77% postoperatively and 87% in the long time follow-up.Conclusion For small acoustic neuroma less than 3 cm in diameter,microsurgical removal via retrosigmoid approach is feasible,but radiosurgery gets better facial nerve preservation than microsurgery.
