title: [Tumorectomy by trans-oral approach of macrosis benign neoplasms in parapharyngeal space (reports of 6 cases)].
abstract: OBJECTIVE
  To discuss the feasibility of tumorectomy by transoral approach of macrosis benign neoplasms in parapharyngeal space.
  
  
  METHODS
  Retrospective analyze 6 patients of macrosis benign neoplasms in parapharyngeal space from January 2005 to May 2008, and all neoplasms were removed by transoral approach. Tracheotomy was performed in 3 cases.
  
  
  RESULTS
  The neoplasms were all removed completely and successfully, and postoperative recovery were good and no complications were found. There were 2 cases of neurofibroma, 2 cases of neurilemmoma, 2 cases of pleomorphic adenoma. There are no recurrence after 20 months to 5 years follow-up.
  
  
  CONCLUSIONS
  Preoperative imaging examination is very important for diagnosis and treatment of benign neoplasm in parapharyngeal space, which is especially helpful to understand the scope of the tumor, and the relationship with carotid artery and vein. On this basis, it is feasible to select the appropriate cases to resect huge benign neoplasm in parapharyngeal space.
