鼻背皮弁の応用と拡大 鼻翼部皮膚悪性腫よう再建への利用

Abstract

The frontonasal flap procedure is a useful method for the repair of relatively larg defects of the central part of nose. Not only the central defect but also the alar defect could be reconstructed by our modified frontonasal or extended frontonasal flap which is composed of the frontonasal flap and the continuous nasolabial flap. The modified frontonasal flap covers alar defects with the nasal tip skin, while the extended frontonasal flap covers large alar defects with both the nasal tip and the opposite alar skin. The donor ala is reconstructed by the continuous nasolabial flap. Four patients underwentthe modified frontonasal flap repair and in two patients the defect was covered by the extended frontonasal flap. All of them were more than 70-years-old. Half of the patients were operated under regional anaesthesia. In all cases, cosmetic results were excellent. One patient complained of nasal obstruction during the first four weeks after operation.
