Application of mucosal flap technique in Draf type Ⅱb/Ⅲ frontal sinus surgery / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

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.
