[Application of mucosal flap technique in Draf type Ⅱb/Ⅲ frontal sinus surgery].

Draf type Ⅱb/Ⅲ frontal sinus surgery has been widely used in clinical practice. They can obtain a wide operating space and sufficient drainage pathways. However, the mucosa around the frontal sinus ostium was removed during the surgery, resulting in bone exposure, and sinus ostium stenosis or atresia may occur after the operation. In recent years, rhinologists at home and abroad have applied various mucosal flaps to cover the exposed bone around the frontal sinus orifice after Draf Ⅱb/Ⅲ frontal sinus surgery, in order to reduce scar formation and bone hyperplasia along with the incidence of frontal sinus ostium stenosis or atresia after surgery. Satisfactory results have been achieved. The article reviews the application of mucosal flap technique in Draf Ⅱb/Ⅲ frontal sinus surgery, in order to promote the clinical research and technical development of this technique in China.Draf Ⅱb/Ⅲ型额窦手术已广泛应用于临床，可获得良好的操作空间和充分的引流通道，但术中切除了额窦口周缘的黏膜，致使骨质裸露，术后可能发生窦口狭窄或闭锁。近年来，国内外学者应用各种黏膜瓣技术来覆盖Draf Ⅱb/Ⅲ型额窦手术后窦口周缘裸露骨面，以期减少瘢痕形成和骨质增生，降低术后窦口狭窄或闭锁的发生率，取得了较理想的效果。本文就黏膜瓣技术在Draf Ⅱb/Ⅲ型额窦手术中的应用进展作一综述，以期推动该技术在我国的临床研究与技术发展。.
