关于声门下区的边界(尤其是上界)文献上意见不一。为了较好地确定声门下区的解剖关系,有利于喉癌的治疗,作者们搜集了50具成人喉标本,男女各半,均于死后24小时内取出,标本未经固定,生前曾作过喉插管或颈部外伤的喉均摒弃不用,测量结果如下: 从声门至甲状软骨下缘的距离(均数):男性为12.28mm;女性为9.64mm。从声门至环状软骨下缘的距离(均数):男性为25.96mm;女性为23.12mm。成人声门下的长度随年龄的变 The literature on the subglottic border (especially the upper bound) disagrees. In order to better determine the anatomic relationship of the subglottic region, is conducive to the treatment of laryngeal cancer, the authors collected 50 adult laryngeal specimens, male and female half, were removed within 24 hours after death, the specimen has not been fixed, had been made before his death The laryngeal cannula or neck trauma throat were abandoned, the measurement results are as follows: From the glottis to the lower edge of thyroid cartilage distance (mean): 12.28mm for men and 9.64mm for women. The distance from the glottis to the lower edge of the cricoid cartilage (mean): 25.96 mm for males and 23.12 mm for females. The length of the adult glottis changes with age
