There have been reports of severe complications from functional endoscopic sinus surgery; however, it is unclear as to how the rate compares with that of the more traditional forms of intranasal surgery. To ascertain this, I circulated a questionnaire to 100 otolaryngologists in Australia known to have an interest in endoscopic nasal surgery and analyzed the results. The results of this survey show that complications are very infrequent and that the rates for functional endoscopic sinus surgery compare favorably with those of the traditional techniques.
