両側前頭開頭での前頭洞処理の工夫  [in Japanese] An Original Surgical Technique of Frontal Sinus Repairment in Bifrontal Craniotomy  [in Japanese]

An opening of the frontal sinus during bifrontal craniotomy is relatively common but may lead to various postoperative complications. The existing surgical repair of the frontal sinus involves total resection of the mucosa, packing of the frontonasal duct, and covering the nasal recess by pericranial flap. We have been using an original surgical technique of frontal sinus repair avoiding mucosal injury, which includes (A) drilling the edge of the frontal sinus without mucosal injury, (B) dissection of the frontal sinus mucosa submucosaly, (C) craniotomy after complete dissection of the mucosa, (D) pushing down the coagulated mucosa to the frontonasal duct, (E) packing by small bone pieces and a collagen sheet with fibrin glue over the nasal recess and (F) covering burr holes with a titanium plate.
