通过对１９５例声门上癌的组织病理学分析，将声门上癌根据肿瘤生长主体部位不同分为会厌癌（５０例）、会厌室带癌（１２４例）、室带癌（１１例）、杓会皱襞癌（１０例）。并根据浸润特点、浸润途径及生长方式、病理分期、组织分化程度几方面进行分析。结果发现会厌室带癌在声门上喉癌中居首位（６３．６％）。浸润途径有２种：①向前上发展由会厌前间隙（１１７例）达会厌舌面（２７例）；②向下发展由声门旁间隙（８９例）至声带表面（３２例），或由前连合区直接浸声带。生长方式多以团块型和纵生团块型为主（７８％）。病理分期Ｐ３、Ｐ４占８０．５％。而会厌室带癌Ｐ３、Ｐ４为５５％。提示会厌室带癌浸润范围较广，组织分化程度Ⅰ～Ⅱ级占７８．５％，以高分化为主。
According to the histopathological analysis of 195 supraglottic carcinomas, the supraglottic carcinoma was divided into epiglottis cancer (50 cases), epiglottis carcinoma (124 cases), ventricular carcinoma (11 cases) , Scoops will collapse (10 cases). And according to the characteristics of infiltration, infiltration and growth patterns, pathological staging, tissue differentiation in several aspects were analyzed. The results found that epiglottis chamber cancer in the supraglottic laryngeal cancer in the first place (63.6%). There are two ways of infiltration: ① forward development of the epiglottis space (117 cases) up to the epiglottis tongue surface (27 cases); ② downward development from the glottis space (89 cases) to the surface of the vocal cords (32 cases), or Baptist band directly from the anterior commissure zone. Most of the growth patterns of clumps and vertical mass (78%). Pathological staging P3, P4 accounted for 80.5%. The epigynous room with cancer P3, P4 is 55%. Tip epiglottis chamber with a wide range of invasive, histological grade Ⅰ ~ Ⅱ grade accounted for 78.5%, mainly to high differentiation.
