目前常用的翻瓣术是内斜切口全厚粘骨膜瓣或改良 Widman 氏瓣,术后最常出现的问题是移植物部份或全部脱落,主要是由于邻间组织瓣不能完全覆盖移植物,即使手术当时能勉强覆盖,愈合过程中的组织收缩亦可在术后使移植物暴露。同时内斜切口瓣常致邻间组织出现凹陷,使该处难于进行菌斑控制,以致软组织长期发炎,甚或移植物脱出。
At present, the commonly used flap surgery is full thickness mucoperiosteal flap or modified Widman's flap. The most common postoperative problem is partial or complete graft loss, mainly due to the fact that the adjacent tissue flap can not completely cover the graft, Even at the time of surgery barely covered, tissue shrinkage during healing can expose the graft after surgery. At the same time, the internal oblique incision flap often caused by the adjacent tissue depression, making it difficult to plaque control, resulting in long-term soft tissue inflammation, or even prolapse of the graft.
