The present report summarizes our experience using endoscopes and neuronavigational tech-niques as an assistance in minimally invasive tool in acoustic neurinoma surgery.Based on the experience in about 100cases done during the last5years using these additional techniques the significant benefit by using both techniques could be proven as absolutely helpful.In our patient collective until now no compli-cations could been detected regarding the use of these options as well as the effectiveness was from very high value.These,for one hand in detecting residual tumor as well as the possibility of controlling the re-sult after the resection using rigid angled endoscopes and for the other hand by the clear efficiency in us-ing neuronavigational systems in planning and performing the approach as well as doing safety drilling by removing the posterior part of the inner auditory channel.Special remarks and recommendations of the technical equipment which has been used are given as well as personal experiences in the operating room set up.Based on our results and experience the use of this two well known techniques in addition to well trained microsurgical techniques can be highly recommended.
