After resection of a hypopharyngeal cancer, utilization of the remaining pharyngeal mucosa in restoring pharyngoesophageal continuity is the procedure of choice. This is possible in most patients. However, a few patients have cancers that involve the posterior pharyngeal wall and esophageal introitus. Resection in this group involves complete removal of a segment of the laryngopharynx and reconstruction with the use of tissue from the adjacent side of the neck, chest, or alimentary canal. Between 1965 and 1974, 44 patients required reconstruction of a pharyngeal defect with the use of adjacent skin flaps or visceral interposition. Pharyngeal reconstruction with the use of these techniques involved multiple operative procedures, a greater morbidity, and a large time investment by the patient and surgeon. Survival of these patients was shorter than survival of patients who had repair by primary closure of the pharyngeal mucosa because of the extent of the primary lesions.
下咽癌切除术后，利用剩余的咽黏膜恢复咽食管连续性是首选的手术方法。大多数患者都可行此手术。然而，少数患者的癌症累及咽后壁和食管入口。该组患者的手术切除包括完全切除一段喉咽，并使用颈部、胸部或消化道相邻部位的组织进行重建。1965年至1974年间，44例患者需要使用相邻皮瓣或内脏植入来重建咽缺损。使用这些技术进行咽重建涉及多个手术步骤，发病率更高，患者和外科医生都需要投入大量时间。由于原发病变范围，这些患者的生存期比通过咽黏膜一期缝合修复的患者短。
