萎缩性鼻炎鼻前孔封闭术为一简单、有效、且病人易于接受的治疗方法。最终还是用切除封闭膜性组织将封闭的鼻通道再开放,但常因发生狭窄而失败。作者推荐应用封闭膜瓣缝合技术,使封闭的鼻孔打开而不会发生狭窄。方法:鼻前孔模拟成以鼻翼侧为斜边的直角三角形,沿三个角平分线切开封闭膜的上皮层,锐形分离并切除,且茌鼻前庭界线稍后方及其中隔相对部分,切除呈套状皮肤,再沿原切线全层切开已去上皮的纤维层和粘膜层,使封闭膜瓣呈三片,修剪后用3—0铬肠线与前 Atrophic rhinitis Nasal anterior closure is a simple, effective, and patient-friendly approach to treatment. Eventually, the closed nasal passages are reopened with excised, closed membranous tissue, but often fail due to stenosis. The authors recommend the use of closed membrane flap suture technology, the closed nostrils open without stenosis. METHODS: The anterior nasal hole was modeled as a right-angled triangle with hypothalamic nostril side. The epithelial layer of the occlusive membrane was incised along the three angle bisector, separated and removed sharply. The vestibular border of the nasal cavity was slightly behind and its opposite part of septum, Cut off the sleeve-like skin, and then cut along the original full-thickness incision to the epithelial fiber layer and mucosal layer, so that the closed flap was three, trimmed with 3-0 chromic gut line and before
