用普鲁士蓝氯仿液对３０具胎儿及５具新生儿的新鲜尸体作下颌骨磨牙区内淋巴管间接注射，观察下颀骨磨牙区集合淋巴管的主要行程：①经下颌磨牙区的牙槽窝沿下颌骨内、外面骨膜的浅面，下行至下颌下淋巴结及角淋巴结；②伴下牙槽神经、血管经下颌孔至翼颌间隙，再行至下颌下淋巴结及角淋巴结；③穿颏孔伴面血管至下颌下淋巴结。以上各淋巴结的输出淋巴管至颈外侧深淋巴结上群。在解剖显微镜下见到淋巴管主要行于肌间隔内。本研究为下颌骨恶性肿瘤病灶切除范围及改良性或功能性颈清扫术，提供解剖学依据。
With Prussian blue chloroform solution of 30 fetuses and 5 newborns of fresh cadavers were injected into the mandibular molars area lymphatic indirect observation of mandibular molars under the main set of lymphatic vessels of the main trip: Along the mandible, the outer surface of the superficial periosteum, down to the submandibular lymph nodes and lymph nodes; ② with the alveolar nerve, blood vessels through the mandibular hole to the wing jaw space, and then to submaxillary lymph nodes and lymph nodes; ③ wear mental foramen With blood vessels to submandibular lymph nodes. The output of each lymph node lymphatic to the deep cervical lymph nodes on the group. Lymphatic vessels were seen mainly in the myenteric space under a dissecting microscope. This study provides an anatomical basis for the resection range of mandibular malignant tumor and modified or functional neck dissection.
