The orbicularis oculi muscle (OOM) is sometimes incorporated with the superficial musculoaponeurotic system (SMAS) flap to provide a stronger flap. While elevating the OOM flap, it is important to avoid injury to the orbicularis branches of the zygomatic nerve. When the orbicularis branches of the zygomatic nerve are identified during the OOM-SMAS flap elevation, a transverse OOM flap was created to preserve the nerve. Postoperative follow-up was 12 months. There was no functional impairment of the OOM in the follow-up period. There are anatomical variations of the orbicularis branches of the zygomatic nerve. When it is identified, a transverse OOM flap incorporating it can be raised to avoid inadvertent injury. Using this method, good results were achieved with virtually no complications.
眼轮匝肌（OOM）有时会与表浅肌肉腱膜系统（SMAS）皮瓣结合使用，以提供更强的皮瓣。在掀起OOM皮瓣时，避免损伤颧神经的眼轮匝肌分支非常重要。在掀起OOM-SMAS皮瓣过程中识别出颧神经的眼轮匝肌分支时，制作横向OOM皮瓣以保留该神经。术后随访12个月。随访期间OOM无功能障碍。颧神经的眼轮匝肌分支存在解剖变异。当识别出该分支时，可以掀起包含它的横向OOM皮瓣以避免意外损伤。使用这种方法，取得了良好的效果，几乎没有并发症。
