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