【摘要】 采用喉连续切片技术重点观察１００例声门上癌向前上发展的病理特点：声门上癌向前上发展平均为７５％，其中会厌室带癌向前上发展的频度最高，为９０％，会厌癌为８１．８％，室带癌为３３．３％，构会壁癌和构区癌未见向前上发展，声门上癌向前上发展以累及会厌前间隙为主，共６Ｏ例，其中累及会厌舌面为４２例次，累及会厌谷为１７例次，累及舌根为１２例次，累及甲状软骨前上部为７例次。通过研究明确了声门上癌向前上发展的规律，加深了对声门上癌的认识，对指导临床实践有重要意义。更多还原

【Abstract】 Pathologic characteristic of supraglottic carcinoma spreading anterosuperiorly in l00 cas-es was investigated by whole-organ sections of the larynx. The results showed that 75%of supraglottic carcinomas were found to spread anterosuperiorly.In these cases, carcinoma in the epiglottis-ventricular fold accounted for 90%;epiglottic carcinoma 8l.8%; and carcinoma in the ventricular fold 33.3%。Carcinoma in the aryepiglottic fold and arytenoid region was not noted to spread anterosuperiorly.In the cases with anterosuperior spreading of supraglottic carcinima, the pre-epiglottic space was most common-ly involved,which accounted for 60%of the cases; while the lingual surface of the epigottis 42% the vallecula l7%; the base of the tongue l2%; and the anterosuperior part of the thyroid cartilage 7%.更多还原
