采用火棉胶包埋,整喉连续大切片技术对30例会厌癌局部生长与扩展特点进行观察。结果是:会厌癌主要位于舌骨下会厌喉面,占93.3％(28/30);局部生长扩展总的趋势是容易向前、向上方进展;其中80％(24/30)侵犯会厌前间隙;主要侵犯途径是通过会厌软骨茎两侧迂回侵入。临床与病理连续切片T分期不符的达53.3％(16/30)。主要是术前对肿瘤向深层浸润估计不足。提示该方法对会厌癌的早诊断、早治疗和预后评价均有重要意义。
Embedding with collodion glue and continuous laryngectomy of the whole laryngectomy were used to observe the local growth and expansion characteristics of 30 cases of epiglottis cancer. The result was that epiglottis was mainly located on the surface of the hyoid bone under the hyoid bone, accounting for 93.3% (28/30); the general trend of local growth was easy to progress forward and upward; 80% (24/30) of the epiglottis was invaded The main invasive route is through the epiglottis cartilage on both sides of the intrusion. The discrepancy between clinical and pathological serial sections was 53.3% (16/30). The preoperative diagnosis of tumor infiltration was mainly insufficient. This method is of great significance for early diagnosis, early treatment and prognosis evaluation of epiglottis cancer.
