舌侧缘淋巴引流与下颌骨舌侧骨膜淋巴管的关系及其临床意义

THE RELATIONSHIP BETWEEN THE LYMPHATIG DRAINAGE OF THE LINGUAL MARGIN AND THE PERIOSTEAL LYMPHATICS OF THE LINGUO-LATERAL MANDIBLE AND ITS CLINICAL SIGNIFICANCE

本文应用十二例新鲜成人尸体的舌－口底－下颌骨－颈部标本，采用淋巴含间接注射法，对舌侧缘淋巴引流及其与下颌骨舌侧骨膜淋巴管的关系进行了观察。初步发现：舌侧缘淋巴引流与下颌骨舌侧骨膜淋巴管没有关系，下颌骨舌则骨膜淋巴管不是舌侧缘向颌下和颈部淋巴结引流的通道因而，舌癌不会通过下颌骨舌侧骨膜淋巴管途径而转移至局部淋巴结。在临床上，对没有直接侵犯至下颌骨舌侧粘骨膜的舌癌病例，保留下颌骨或保持其连续性是可行的。

The lymphatic drainage of the lingual margin and the periosteal lympha-tics of the linguo-lateral mandible in 12 freshhuman adult cadaveis were studied with themethod of indirect injection into the lymphatics,Preliminary finding:There are norelationship between the lymphatic drainage of the lingual margin and the periosteallymphatics of the linguolatcral mandible. The periosteal lymphatics of the linguolateralmandible isn’t a draining channel from the iingual margin to the submandibular andthe cervical lymph nodes.Therefore,the lingual carcinoma didn’t metastaslze to thelocal lymph nodes by the periosteal lymphatics of the linguo-lateral mandible. It issultable that reserving the mandible or keeping its continuity in the lingual carcinomacases that the mucoperiosteum of the linguo-lateral mandible hasn’t been directly inva-ded.
