Powered instrumentation in dissection of the frontal recess

The use of powered instrumentation in functional endoscopic sinus surgery has become very popular due to its safety and thoroughness. An area which has been more problematic in the use of this technique has been the frontal recess, due to its anatomic location and associated risk of serious complications. We have done a number of powered dissections of the frontal recess as a surgical treatment of refractory frontal sinusitis, and find that it is extremely safe and effective. The ability of the powered devices to preserve normal mucosa allows an adequate surgical approach while significantly decreasing the postoperative risk of frontal recess stenosis and reocclusion. We feel that powered dissection of the frontal recess offers a significant advantage over standard techniques in this anatomic location.
