Lymphoscintigraphy reveals inconsistencies in our knowledge of the lymphatic anatomy of the external ear.
Fifteen external ears from 9 unembalmed human cadavers were studied. Six percent hydrogen peroxide was used to find the lymphatic vessels using a surgical microscope. They were injected with a radio-opaque mixture, dissected, photographed, and radiographed to demonstrate lymphatic vessels in the tissue. Final results were transferred to the computer for analysis.
Four groups of lymph collecting vessels were found. The anterior branch, in all specimens, drained directly or indirectly (having merged with a vessel descending from the scalp) into the preauricular lymph nodes. The superior, middle, and inferior (lobule) branches drained to their multiple first tier lymph nodes.
An accurate lymphatic map of the external ear is described to upgrade our anatomic knowledge. It will be of benefit for the clinical management of malignancies in this region.
淋巴闪烁显影术揭示了我们对外耳淋巴管解剖知识的不一致。
对 9 具未经防腐处理的人体尸体的 15 只外耳进行了研究。使用手术显微镜用 6%过氧化氢寻找淋巴管。将放射性不透射线的混合物注入其中，进行解剖、拍照和拍摄射线照片，以显示组织中的淋巴管。最终结果被转移到计算机上进行分析。
发现了四组淋巴收集管。在前支中，所有标本均直接或间接（与来自头皮的下降血管合并）引流至耳前淋巴结。上、中、下（小叶）分支引流至多个第一级淋巴结。
描述了外耳的准确淋巴管图，以提升我们的解剖知识。这将有利于该区域恶性肿瘤的临床治疗。
