经过许多学者的努力,对喉胚胎学及喉淋巴供应的研究,和手术方法的改进,使喉癌的手术治疗可以按癌瘤的位置而分别进行,并取得良好效果,且保留发音功能。例如在胚胎学方面认为声门上部来自口咽原基,而声门及声门下部来自气管支气管原基,故声门上部之治疗完全可与声门分开。而由于淋巴供应的研究得知真声带及喉室淋巴管少,声门上及声门下 After the efforts of many scholars, the research of laryngeal and embryoology, the supply of laryngeal and lymph, and the improvement of surgical methods make the surgical treatment of laryngeal cancer can be carried out respectively according to the location of the tumor, and the good effect is achieved, and the pronunciation function is preserved. For example, in embryology that the upper part of the glottis is from the orogenic base of the oropharynx, and the glottis and glottis are from the tracheobronchial base in the lower part of the upper part of the treatment of the supraglottic and the glottis can be separated. However, due to lymphatic supply studies have found that the true vocal cord and laryngeal lymphatic less, supraglottic and supraglottic
