Abstract

Background: Despite indications of a close interaction between the trigeminal (CN V) and facial nerve (CN VII) within the buccinator muscle, a combination of anatomical dissection and histological analysis has not been reported.

Methods: Five formalin-fixed and fresh-frozen hemifaces were dissected to reveal the buccal fat pad, the buccinator muscle, and anastomotic connections between CN V and CN VII within it. Samples were taken for histological processing and immunostaining.

Results: Branches of CN V and CN VII formed pronounced sensorimotor anastomotic connections in and surrounding the buccinator muscle. These findings were histologically evident with close intramuscular coupling of sensory and motor fibers. There was an evident but gradual shift from motor to sensory fibers in the interconnections when analyzing them from the side of CN V toward the side of CN VII and vice versa.

Conclusions: These results further elucidate connections between CN V and CN VII and their possible role in proprioception of the facial muscles.

颊肌中面神经和三叉神经之间感觉运动连接的解剖学和组织学。

背景：尽管有迹象表明三叉神经（CN V）和面神经（CN VII）在颊舌肌内有密切的相互作用，但将解剖学解剖和组织学分析相结合的方法尚未见报道：方法：解剖 5 个福尔马林固定和新鲜冷冻的半面，以显示颊脂垫、颊舌肌以及其中 CN V 和 CN VII 之间的吻合连接。取样进行组织学处理和免疫染色：结果：CN V 和 CN VII 的分支在颊肌内部和周围形成了明显的感觉运动吻合连接。这些发现在组织学上非常明显，感觉纤维和运动纤维在肌肉内紧密耦合。当从 CN V 侧向 CN VII 侧分析时，相互连接明显但逐渐从运动纤维转向感觉纤维，反之亦然：这些结果进一步阐明了 CN V 和 CN VII 之间的联系及其在面部肌肉本体感觉中可能发挥的作用。
