摘　　要：目的：探讨跨声门癌浸润声门旁间隙和会厌前间隙的特点及与颈淋巴结转移关系。方法：对５０例跨声门癌喉切除标本和３０例３５侧颈廓清大体标本行连续切片观察。结果：声门旁间隙的浸润率为７８％ ，颈淋巴结转移率为４９％ 。会厌前间隙的浸润率为４６％ ，颈淋巴结转移率为６５％ 。随着肿瘤Ｔ分级增高，肿瘤增大，声门旁间隙和会厌前间隙的浸润率增加。结论：声门旁间隙易受累，并易突破该间隙；浸润会厌前间隙的途径与声门上癌不同，支持跨声门癌为单独一型。Objective:The study was to explore the characters of transglottic cancer invading paraglottic space(PGS),and preepiglottic space(PES) and its relationship with cervical lymph nodes metastasis.Methods:50 cases of laryngectomy and 35 cases of neck dissection specimens were studied by serisl section observation method.Results:In transglottic cancer, the invasion rate of PGS was 78%(39/50), the matastatic rate of cervical lymph nodes was 49%; the invasion rate of PES was 46%, the matastatic rate of cervical lymph nodes was 65%. The invasion rates of PGS, PES were increased with the increasing degree of clinical T stage and tumor volume.Methods:50 cases of laryngectomy and 35 cases of neck dissection specimens were studied by serisl section observation method.Results:In transglottic cancer, the invasion rate of PGS was 78%(39/50), the matastatic rate of cervical lymph nodes was 49%; the invasion rate of PES was 46%, the matastatic rate of cervical lymph nodes was 65%.

The invasion rates of PGS, PES were increased with the increasing degree of clinical T stage and tumor volume.Conclusion:Invasion rate of PGS in transglottic cancer is high, and tumors break through this space easily. Invasion route of PES is different in transglottic cancer and supraglottic cancer. The au
