会厌室带癌局部生长扩展特点的观察——附50例会厌室带癌喉标本连续大切片观察

LOCAL GROWTH AND EXPANDING CHARACTERISTICS OF FPIGLOTTO-VENTRICULAR BAND CARCINOMA——The observation of serial section of the larynx specimens of 50 cases

采用火棉胶包埋,整喉连续大切片技术,对声门上癌中比较多见的50例会厌室带癌局部生长扩展特点进行了研究。指出,会厌室带癌具有发病率高,侵犯范围广而深的特点,是声门上喉癌中最常见的一种类型。占同期声门上癌的45.5%。认为会厌室带癌侵犯声门旁间隙的问题不容忽视,而声门旁间隙又是肿瘤向四周扩展的主要途径。喉部分切除术失败往往是由于对肿瘤侵犯声门旁间隙的程度估计不足所致。并指出会厌室带癌手术治疗应行全喉切除或水平垂直半喉切除术。

We studied the local growth and expanding characteristics of epiglotto-ventricular band carcinoma in 50 cases by celloidin-inbedding method and serial section technique, It was showed that epiglotto-ventricular carcinoma had features of high insidence and wide invadation, which was a common type of supraglottic carcinoma, 45.5% supraglottic carcinoma at the came stage was diagnosed as epiglotto-ventricular carcinoma. We thought that the problem in epiglotto-ventricular carcinoma invading paraglottic space was unignorable, and paraglottic space was a important route for tumor-spreading about it, The incorrcct estimation about paraglottic space which is invaded by the tumor is contribute to the failure of partial laryngectomy. Surgical treatment of epiglotto-ventricular carcinoma should be made not only total laryngectomy or vertical-horizontal hemilaryngectomy, but neck dissection also.
