The innervated platysma musculocutaneous flap replaces facial tissue with like tissue. The thinness of the flap, the color match, and the presence of functional subcutaneous muscle are unmatched by any other flap that does not originate on the face. The superior blood supply is reliably provided by the submental branch of the facial artery, creating a reliable axial flap. Rotation of the muscle into the cheek aligns the fibers of the platysma muscle to provide upward pull on the oral commissure to assist with facial animation. Three cases of innervated platysma flap rotation to reconstruct the contour of the cheek and assist with facial animation are reported. All the patients achieved an improved facial contour and all flaps demonstrated noticeable contraction, augmenting facial animation.
带神经支配的颈阔肌肌皮瓣用相似组织替代面部组织。该皮瓣的薄度、颜色匹配以及功能性皮下肌肉的存在是其他非面部起源的皮瓣所无法比拟的。面动脉颏下支可靠地提供了优越的血供，形成了可靠的轴型皮瓣。将肌肉旋转至颊部可使颈阔肌纤维对齐，从而向上牵拉口角以辅助面部表情活动。本文报告了3例采用带神经支配的颈阔肌皮瓣旋转来重建颊部轮廓并辅助面部表情活动的病例。所有患者的面部轮廓均得到改善，且所有皮瓣均表现出明显的收缩，增强了面部表情活动。
