红唇及红唇缘的外伤性缺损,并非少见,通常是采用包括肌肉的唇楔形切除来修复。虽然切除成人1/3 的下唇不致产生畸形,而切除上唇则可导致人中柱的歪斜,唇切除常需切除缺损邻近的正常组织,这在治疗恶性肿瘤是可以接受的,而在修复外伤性唇缺损则不然。为了解决这种缺损的修复,作者提出了以下技术。适应症局限性红唇缺损(包括或不包括红唇缘)且邻近缺损的唇组织无严重挫伤及显著的肌肉缺失。手术方法麻醉下创口扩创成方形,过氧化氢液冲洗,设计两个VY型岛状推进瓣:一个从缺损的皮肤
Traumatic defects of the lips and red lips are not uncommon and are usually repaired by lip wedge resection including the muscles. Although removal of the upper third of the adult's lower lip will not cause deformity, and removal of the upper lip can lead to skew in the column, lip resection often need to remove the adjacent normal tissue defect, which is acceptable in the treatment of malignant tumors, and in the repair of trauma Sexual lip defect is not. In order to solve this defect repair, the authors proposed the following techniques. Indications Localized lip defects (with or without red lip) and adjacent defect lip tissue without severe contusion and significant muscle loss. Surgical methods under anesthesia wounds expanded into a square, hydrogen peroxide solution flushing, the design of two VY-shaped island-shaped propulsion valve: a defect from the skin
