title: Complications following powered endoscopic sinus surgery: an 11 year study on 1190 patients in a single institute in Israel.
abstract: BACKGROUND
  Over the past 20 years, advances in endoscopic sinus surgery (ESS) techniques have led to widespread applications of this technology in both adult and pediatric populations with better results and lower morbidity.
  
  
  OBJECTIVE
  To update data regarding the rate of minor and major complications following ESS procedures that used powered instrumentation.
  
  
  METHODS
  We retrospectively reviewed the charts of all patients who, with general anesthesia, underwent ESS utilizing powered instrumentation between January 1996 and December 2006. Age, gender, indication for surgery, length of hospitalization, and type and rate of surgical complications were recorded.
  
  
  RESULTS
  A total of 1190 patients were included in our study (1309 surgeries). The male:female ratio was 1.7:1.0 and the average age was 39 years (range 4-86 years). The most common indication for surgery was chronic rhinosinusitis. The rate of major complications was 0.31% and that of minor complications 1.37%. The only major complication that occurred was cerebrospinal fluid leak. The minor complications included epistaxis, periorbital emphysema, ecchymosis and mucocele formation.
  
  
  CONCLUSIONS
  Compared to previously published series, the rate of major and minor complications in our study was low. The results indicate that the use of powered instruments during ESS is safe.
