修复下咽颈段食管癌术后缺损是一个复杂的问题。作者报道了采用喉气管瓣修复13例。累及食管上段的下咽癌、环后癌、梨状窝癌和颈段食管癌切除术后缺损及手术方法。其中环后癌3例，梨状窝癌5例，颈段食管癌3例，咽后壁癌2例。术后一期愈合9例，咽癌2例，吻合口狭窄2例。5年随访生存8例（61．5％）。证明采用喉气管瓣移植修复颈段食管缺损之方法简单，术后咽食管功能恢复好，不易狭窄。
Repairing the defect of esophageal carcinoma of the lower pharyngeal is a complicated problem. The authors reported the use of laryngotracheal flap repair in 13 cases. Esophageal involvement of hypopharyngeal carcinoma, posterior ring cancer, pyriform sinus carcinoma, and cervical resection of esophageal cancer after surgery and surgical methods. Among them, there were 3 cases of posterior ring carcinoma, 5 cases of piriform carcinoma, 3 cases of cervical esophageal carcinoma, and 2 cases of posterior pharyngeal carcinoma. Nine cases were healed at the first postoperative stage, 2 cases were pharyngeal cancer, and 2 cases were anastomotic stenosis. Five years of follow-up survived in 8 patients (61.5%). The method of repairing cervical esophageal defects with laryngotracheal flap transplantation is proved to be simple and the postoperative pharyngoesophageal function is well restored and difficult to be narrowed.
