下唇全缺损,通常采用双侧上唇方形皮瓣或颊部扇形组织瓣整复,均需二期行口角开大术。若转移远处皮瓣修复下唇则需几次分期手术,常需数月时间。临床使用的 Bernard 法主要适用于修复下唇半缺损,若用于修复下唇全缺损,则因张力过大,中线缝合处易感染裂开。术后下唇过于紧张,不仅美观欠佳,功能也受限。为此,我们改进了手术方法,即将 Bernard法仅在下颌龈颊沟作松弛切口的唇颊组织瓣改为全层切开,形成两颊矩形滑行组织瓣,
Lower lip full defect, usually with bilateral upper lip square flap or flap tissue flap chelation, are required to open the mouth of two major open surgery. If the transfer of distant flaps to repair the lower lip will need several staged surgery, often take a few months time. Clinical Bernard method is mainly used to repair the lower lip half-defect, if used to repair the entire lower lip defect, the tension is too large, the midline suture easily infected split open. Postoperative lower lip too nervous, not only poor in appearance, function is also limited. To this end, we have improved the surgical method, that is, the Bernard method only in the gingival cheek groove for relaxation incision lip cheek tissue flap changed to full-thickness incision, the formation of cheek rectangular gliding flap,
