Although accessory foramina of a human mandible are consistent findings their contents still causes confusions. The study was undertaken to determine the contents of accessory foramina on the medial aspect of mandibular symphysis. Dissection of 21 human cadaveric heads revealed the presence of neurovascular bundle in accessory foramina. Macroscopically it was observed that the bundle was formed by branches of mylohyoid nerve, sublingual artery and accompanying veins. Histological observations proved that the contents of accessory foramina were formed by an artery accompanied by a nerve. Immunohistological investigations using neuron-specific-enolase (NSE) and S-100 protein showed positive reactions in nerve axons and confirmed the presence of the nerve in accessory foramina. In conclusion, the possible role and clinical importance of accessory foramina on the internal surface of mandibular body was discussed.
尽管人类下颌骨的副孔是一致存在的，但它们的内容仍然存在混淆。本研究旨在确定下颌联合内侧副孔的内容物。对 21 个人体头颅标本进行解剖，发现副孔内有神经血管束。宏观上观察到，该束由下颌舌骨肌神经、舌下动脉及其伴行静脉的分支组成。组织学观察证实，副孔的内容物由伴行的动脉和神经组成。使用神经元特异性烯醇化酶 (NSE) 和 S-100 蛋白进行免疫组织化学研究显示，神经轴突呈阳性反应，证实了神经在副孔中的存在。总之，讨论了下颌体内部表面副孔的可能作用和临床重要性。
