摘要
目的:研究颌外动脉的重要毗邻关系。方法:逐层解剖60具完整的头颈标本(每具仅解剖一侧)。观察颌外动脉与颌下腺、面前静脉、面神经下颌缘支及颌下淋巴结之间的毗邻关系。结果:1颌外动脉位于颌下腺深面者占60%,穿越腺实质者占38.3%,行走于腺体表面者占1.7%。2颌外动脉位于下颌缘支深面者占90%,位于浅面者占5%,下颌缘支环抱或夹持颌外动脉者占5%。3颌外动脉与面前静脉伴行者占11.7%,不与面前静脉伴行者占88.3%。4颌外动脉前后均有恒定淋巴结相毗邻。结论:颌外动脉毗邻关系较为复杂,了解其与周围的这些重要结构的关系,有着重要的临床意义。
Objective:To investigate the important adjacent relationship of the external maxillary artery.Methods: 60 pieces of complete head neck samples were dissected layer by layer (only one side per sample),then the adjacent structures of the external maxillary artery, such as the submandibular gland, the anterior facial vein, the marginal mandibular branches of facial nerve and the submandibular lymphatic nodes were observed.Results: ①60% of external maxillary artery lay on the bottom of submandibular gland, 38.3% went through the gland and 1.7% on the surface of the gland; ②90% of marginal mandibular branches of facial nerve went through the surface of external maxillary artery, 5% on the bottom and 5% encircled and gripped the artery; ③6.7% of anterior facial vein lay on the bottom of submandibular gland and accompanied external maxillary artery, 5% went through the gland and accompanied the artery, 88.3% went on the surface of the gland and didn't accompany the artery; ④There were constant lymphatic nodes in front of and behind the external maxillary artery. Conclusion: The adjacent relationship of external maxillary artery is complex, and it is significant for doctors to know the above important structures around the artery.\;
