鳞状细胞癌累及前下颌骨者约占口腔恶性肿瘤的10％,因手术切除前下颌骨边缘及口底软组织而造成的缺损,其修复比较困难。本文介绍一种使用颏肌瓣联合皮肤移植片的方法修复前下颌骨缺损。 手术方法 将颏肌上1/3附着于唇侧端游离,然后反转覆盖暴露的下颌骨,并与口底肌层缝合。再将中厚层皮肤移植片覆盖舌缺损处、口底、颏肌瓣及唇前庭,注意要使皮肤移植片与颏肌瓣底部缝合,以便形成固有唇前庭。最后,放置预先制备的树脂固定模并与颌
Squamous cell carcinoma involving the anterior mandibular about 10% of oral malignancies, due to surgical removal of the mandibular margin and soft tissue defects caused by mouth, its repair more difficult. This article describes a method using the chin muscle flap combined with skin grafts to repair the anterior mandibular defect. Surgical methods will be attached to the labial side of the gluteal muscle free side, then reverse cover the exposed mandible, and suture with the floor of the myometrium. Then the thick layer of skin graft covering the tongue defect, the mouth, chin muscle flap and lip vestibule, pay attention to make the skin graft and chin muscle flap at the bottom of the suture in order to form the inherent lip vestibule. Finally, place the pre-made resin mold and attach it to the jaws
