The present report summarizes our experience using endoscopes and neuronavigational techniques as an assistance in minimally invasive tool in acoustic neurinoma surgery. Based on the experience in about 100 cases done during the last 5 years using these additional techniques the significant benefit by using both techniques could be proven as absolutely helpful. In our patient collective until now no complications 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 result after the resection using rigid angled endoscopes and for the other hand by the clear efficiency in using 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.

The present report should summarize our experience using minimally invasive techniques in acoustic neurinoma surgery at the Neurosurgical Department,University of Vienna,Austria .Based on the experience of about 687 cases ub a 20year time period our mostly used techniques will be presented. This is a minimal innvasive individual adapted approach,specified intraoperative strategy and dissection tech-niques (e.g.water jet dissection,ultrasonic aspirator CUSA),the use of neuronavigational systems and the use of endoscope assisted surgery.With respect to the Limited space of place precise citations to further textbooks of the authors handling with this topic will be given. Finally our results using these techniques are presented and further future perspectives in the treatment of these pathology(radiosurgery)will be dis-cussed.

1例小切口内镜辅助下左侧甲状腺叶切除术的手术配合

随着腔镜技术的发展，小切口内镜辅助下左侧甲状腺叶切除术（minimal invasive endoscope assisted thyroidetomy，MIET）已成为目前头颈外科医生公认的甲状腺癌微创手术治疗方法之一。该手术是通过内镜协助，利用超声刀、频电刀等达到甲状腺癌根治的目的，具有创伤小、出血少、疼痛轻等优点。以下为1例甲状腺癌患者施行MIET手术的手术配合。
