title: [Endoscopic posterior septectomy for patients with nasopharyngeal tumor].
abstract: OBJECTIVE
  To explore the techniques, advantages and disadvantages, indications and cautions of a surgical approach for the resection of nasopharyngeal tumor.
  
  
  METHODS
  Ten cases with nasopharyngeal tumors were recruited in this study, of them, 3 cases with residual nasopharyngeal carcinoma after chemoradiotherapy, 2 cases with cavernous angioma, 2 cases with benign mixed tumor, 1 malignant mixed tumor, 1 adenoid cystic carcinoma, and 1 chordoma. All patients underwent endoscopic resection of posteroinferior quarter part of nasal septum, and then the removal of nasopharyngeal tumors through bilateral transnasal approach.
  
  
  RESULTS
  Total resection of the tumor was achieved for all cases without severe surgical complications. All cases with benign tumors, with following-up of 6-18 months, showed no recurrence. Of 6 cases with malignant tumors, with following-up of 12-48 months, 5 cases showed no recurrence, and 1 case was suspected to relapse one year postoperatively, but not with any lesion enlargement after another 6 month follow-up.
  
  
  CONCLUSIONS
  Posteroinferior quarter part of nasal septectomy is preferred for endoscopic resection of nasopharyngeal tumors because it can provide a panoramic view on nasopharyngeal cavity and tumors, thus, facilitating the removal of nasopharyngeal tumors.
