由于下咽部(喉咽部)位置隐蔽,下咽恶性肿瘤临床早期症状缺乏,难以早期诊断,发现时往往已经处于进展期,甚至侵犯颈段食管,5年生存率仅在15%～47%之间[1]。研究表明,广泛的下咽及颈段食管切除和手术后化放疗能够在一定程度上提高5年生存率,但是切除以后带来的言语和吞咽功能障碍严重影响了患者的生存质量。因此,如何修复手术后缺损,重建患者的吞咽和言语功能是头颈外科医师面临的一大挑战。
Due to the obscure hypopharynx (hypopharynx) position, the early clinical symptoms of hypopharyngeal malignant tumor are scarce, so it is difficult to diagnose early. When it is found, it is often in advanced stage and even invades the cervical esophagus. The 5-year survival rate is only 15% -47% Between [1]. Studies have shown that extensive hypopharyngeal and cervical esophagectomy and postoperative chemoradiotherapy can improve 5-year survival rate to some extent, but speech and swallowing dysfunction after resection have seriously affected the quality of life of patients. Therefore, how to repair postoperative defects and reconstruct the swallowing and speech function of patients is a big challenge for head and neck surgeons.
