Endoscopic endonasal approach resection for anterior skull base, pterygopalatine fossa and infratemporal fossa tumors: retrospective analysis of 73 patients

Objective: To summarize the clinical experience with endoscopic transnasal resection of nasal skull- base neoplasms, which involved anterior skull base, pterygopalatine fossa, nfratemporal fossa.

Methods: Clinical data from 73 patients performed on endoscopic transnasal resection of nasal skull-base neoplasms were analyzed retrospectively.

Results: Total tumor removal was obtained in 54 cases, subtotal removal in 19 cases. In 16 cases of benign tumor, the postoperative survival rate was 100%; Malignancy in 57 cases, of which 16 patients were died, and half-year survival rate was 71.9%.

Conclusions: Endoscopic endonasal approach be able to fully reveal and re- moval of lesions involving the anterior skull base, pterygopalatine fossa and infratemporal fossa. The approach is feasible and safe.
