The surgical therapy for velopharyngeal incompetence has always been a challenging problem. In spite of the surgical choices of palatal pushback, pharyngeal flap, pharyngoplasty, muscle transfers, and pharyngeal wall implants, the reported failure rate has varied from 10% to 50%. A group of ten patients with velopharyngeal insufficiency is presented, two posttonsillectomy and adenoidectomy, three secondary to congenital deficiencies, and five following palatal and pharyngeal paralysis secondary to severe closed head injuries. The technique and experience with the lateral port control pharyngeal flap is discussed.
腭咽闭合不全的外科治疗一直是个具有挑战性的问题。尽管有腭后推、咽瓣、咽成形术、肌肉转移和咽壁植入等手术选择，但报道的失败率在10%至50%之间。本文介绍了一组十例腭咽功能不全的患者，其中两例为扁桃体切除和腺样体切除术后，三例继发于先天性缺陷，五例继发于严重闭合性颅脑损伤后的腭咽麻痹。文中讨论了侧端口控制咽瓣的技术和经验。
