[Endoscopic transnasal surgery for anterior skull base lesions].

Objective: To investigate the feasibility and subject range of endoscopic transnasal surgery for anterior skull base lesions.

Method: Six patients affected with anterior skull base diseases in recent years were studied. The lesions were included 3 cases of cen encephalocele, 2 of cerebrospinal rhinorrhea and one of left retrobulbar tumor. All 6 patients received endoscopic transnasal surgery under general anesthesia.

Result: All patients had accepted successful one-stage surgeries without any complications.

Conclusion: Endoscopic transnasal surgery for some anterior skull base lesions has the advantages of tiny injuring, quick recovery and few complications. But surgical indications must be controlled seriously. The operator must hold skillful anatomic intelligence, surgical technique and experiences as well as advanced surgical apparatuses.
