咽和喉部恶性肿瘤患者,由于术前多曾接受过放疗,加之病变广泛,术后可并发巨大咽瘘。用以往的诸种方法,只有70%病例获得治愈。为此,著者改用了“靴”形皮-肌瓣做咽瘘成形术,以胸锁乳突肌作为成形材料和营养蒂。在临床应用前曾先行观察了胸锁乳突肌及其附近区域的解剖-形态学情况,以了解其神经分布和血液供给的特点,为此曾解剖年龄为17～85岁的70具尸体。发现副神经可在不同的高度进入胸锁乳突肌,最常见的(60.1%)是在其上1/3处,其次(32.6%)在其中部,最少的(3.7%)是在下
Pharyngeal and laryngeal cancer patients, due to preoperative radiotherapy have received more, combined with extensive lesions, postoperative complications may be a huge pharyngeal fistula. With the previous methods, only 70% of cases were cured. To this end, the author switched to the “boots” shaped skin - muscle fistula surgery to sternocleidomastoid muscle as shaping material and nutrition pedicle. Before clinical application, we first observed the anatomical-morphological characteristics of the sternocleidomastoid muscle and its vicinity in order to understand the characteristics of its nerve distribution and blood supply. For this purpose, 70 bodies aged 17-85 years were dissected. The accessory nerve was found to enter the sternocleidomastoid at different heights, the most common (60.1%) being at the top 1/3, followed by the middle (32.6%), and the fewest (3.7%) being at the bottom
