Endoscopic vidian neurectomy assisted by power instrumentation and coblation.

Vidian neurectomy has been used to manage intractable vasomotor rhinitis for decades. After the introduction of endoscopic sinus surgery in the 1980s, transnasal endoscopic vidian neurectomy (EVN) was subsequently reported. The most common problem in performing EVN was excessive bleeding from the pterygopalatine fossa. The complexity and vascularity of the pterygopalatine fossa can cause bloody surgical fields and prevent complete neurectomy. In response to this surgical problem, a procedure was developed to use powered instrumentation and coblation during EVN. There were eight cases of EVNs (16 neurectomies) assisted by power instrumentation and coblation from December 2011 to May 2012. The average blood loss of these cases was 37.5 mL (range, 25-50 mL). The average surgical time of each neurectomy was 27.4 minutes (range, 20-35 minutes). No complications occurred in any of the eight cases. Very limited bleeding and less thermal damage were noted while achieving a complete neurectomy.
