The translamina terminalis approach for microsurgical resection of anterochiasmatic sellar tumour

Objective To study the operative approach and microsurgical technique of translamina terminalis approach on anterochiasmatic sellar tumour. Methods The clinical data and the follow-up result of 23 patients with anterochiasmatic sellar tumour who were treated surgically through translamina terminalis approach were analyzed retrospectively from February 2001 to May 2007. Results Among 23 patients, total resection was performed in 13 cases,secondary resection in 6 cases, partial resection in 4 cases. All patients had good results without operation death. Three recurred cases were found during the follow-up period of 6 months to 4 years. Conclusions The translamina terminalis approach for microsurgical resection of anterochiasmatic sellar tumour is an effective method by mastering anatomy characteristics of saddle area interspaces. Perfect microsurgical skill, protection of important structures in saddle area and treatment of complication in time ware the basement of achieving fine curative effect.
