【摘要】 在30具(男23.女7)共60例成人尸体上观察与测量了咬肌的动脉与神经来源、咬肌神经的分支以及肌内构筑、咬肌由上颌动脉咬肌支和邻近动脉肌支供血,面动脉与面横动脉的咬肌支为其主要营养动脉.咬肌神经在肌内可分成单干和双干两型,前者居多,两型中其肌内分支间均有吻合.就结果对有关颌面外科应用问题进行了探讨.更多还原

【Abstract】 The origin, branches, and intramuscular architecture of the artery and the nerve of 60 masseter muscles were observed and measured with stereoscopy in 30 human autopsy cases. The branches of the facial artery and the facial transverse artery were main nutritional vessels of masseter muscles. The masseteric nerves were divieded into two types: single and double trunk. The former was observed in 75% ±5.5 samples, and the later in 25% ±5.5 samples. The clinic application of masseter muscles was discussed in this paper.更多还原
