结果：颊肌粘膜瓣的感觉神经是颊神经，运动神经为面神经的颊支，其在第2、3磨牙相对的颊区与颊神经交通。

Results: the sensory nerve is buccal nerve. The motor nerve is buccal branches of the facial nerve, which communicates with the buccal nerve in the 2nd and the 3rd mandibular molar region.

方法：15例动脉内注红色乳胶的头颈部标本，解剖双侧面动脉发出至口角外上方、颧弓下方颊区内的直接皮支，测量皮支的外径、长度。

Methods: 15 cadavers perfused beforehand with red latex were dissected to separate the direct buccal cutaneous branch of facial artery. The diameter and length of the cutaneous branch were measured.
