Vascularized anteriorly based pericranial flap for frontal sinus obliteration

Even with the widespread use of minimally invasive endoscopic sinus surgery, the treatment of complicated frontal sinus disease remains very challenging, and obliteration of the sinus often is indicated. A variety of materials have been used for obliteration of the frontal sinus; however, the search for the ideal technique persists. The well-vascularized anteriorly based pericranial flap, described in this article, is a safe, effective, and viable method of frontal sinus obliteration.
