作者对30例晚期喉癌行根治性手术切除,用胸大肌皮瓣Ⅰ期修复颈前大块软组织缺损、下咽重建和修复颈段食管,部分病人用此肌皮瓣Ⅱ期修复咽瘘,均取得了满意效果。讨论了胸大肌皮瓣的优缺点,制作中的注意事项。作者认为胸大肌皮瓣用途广泛,几乎可以不受限制地修复头颈部肿瘤切除后的组织缺损和功能重建。 The authors performed radical surgical resection of advanced laryngeal cancer in 30 cases. The pectoralis major myocutaneous flap was used to repair large soft tissue defects in the anterior neck, reconstruction of the hypopharynx, and repair of the esophagus in the neck. Some patients used the myocutaneous flap to repair the pharyngeal fistula in phase II. Both have achieved satisfactory results. The advantages and disadvantages of pectoralis major myocutaneous flaps were discussed, and precautions during production were discussed. The authors believe that pectoralis major myocutaneous flaps are widely used to repair tissue defects and functional reconstructions after resection of head and neck tumors.
