title: Coblation assisted transnasal endoscopic resection of nasopharyngeal cyst: 10 years experience and outcomes.
abstract: OBJECTIVE
  To determine the outcomes of coblation assisted transnasal endoscopic resection of nasopharyngeal cyst.
  
  
  METHODS
  Retrospective chart review outcomes in 12 patients who underwent endoscopic resect cysts of the nasopharynx at our department between 2001 and 2010. Twelve patient, aged 28 to 71 years, with cysts of the nasopharynx. The outcome variables of complications and the rate of recurrence were analyzed, respectively.
  
  
  RESULTS
  In 12 cases, retention cysts in 2 cases, branchial cyst in 1 case, adenoid middle fossa cyst infection in 6 cases, Tornwaldt's cyst in 3 cases. The use of the coblation device was associated with a significant decrease in blood loss. There were no postoperative complications, and the overall follow-up period was 2-7 years and shows no signs of recurrence.
  
  
  CONCLUSIONS
  We describe transnasal endoscopic procedures to resect cysts of the nasopharynx. We found that radiofrequency coblation is a useful and safe tool associated with minimal blood loss in the resection of these cysts. In our experience, it has been a highly successful, safe, and effective procedure.
