title: [Clinical application of endoscopy-assisted resection of tumors in parapharyngeal space].
abstract: OBJECTIVE
  To explore the advancement of the endoscopic video system in parapharyngeal space tumor resection.
  
  
  METHODS
  Thirty cases parapharyngeal space tumor patients underwent endoscopy-assisted tumors resection in otorhinolaryngology-head and neck surgery of Tianjin First Central Hospital. The passway included trans-oral cavity in 6 cases, 21 cases with trans-neck side and trans-neck-parotid gland in 3 cases.
  
  
  RESULTS
  Tumors of all cases were completely resected, without residual tumor. It was included 23 cases of benign tumors (14 cases of parotid pleomorphic adenoma, 8 cases of neurilemmoma, lymph node tuberculosis in 1 case), malignant tumor in 7 cases (2 cases of metastatic carcinoma, 2 cases of malignant mixed tumor, 1 case of malignant neurilemmoma, 2 cases of adenoid cystic carcinoma). Tongue deflection was recorded in 2 cases. There were neither wound infection or bleeding. All the cases were followed up after operation without recurrence. Seven cases of malignant tumor patients were all alive with follow-up 1 year in 1 case, 3 years in 4 cases, 2 cases for five years.
  
  
  CONCLUSIONS
  Endoscopy-assisted tumors resection can deal with visual lesion corner and allow previous part no visibility surgery into all operation under direct vision. It contributed to improve the quality of operation, reduce the surgery complication. It was worth to be wide spreaded in clinic.
