腭咽括约肌对于说话和吞咽功能至关重要。腭咽闭合不全（VPI）导致鼻音过强和鼻返流。VPI的常见原因是先天性腭裂，但耳鼻喉科医生有时会在手术后遇到医源性VPI。用假体治疗VPI通常是成功的，但并不总是耐受良好。已经提出了许多外科手术来矫正腭长度或扩大咽后壁。我们报告两例自体肋软骨被用作植入物增强。这种方法是指和有效的，当咽喉赤字小于5毫米。自体肋软骨植入程序是安全和可逆的，可以预期煽动最小的主机反应。
The velopharyngeal sphincter is critical in enabling the functions of speaking and swallowing. Velopharyngeal insufficiency (VPI) results in hypernasal speech and nasal regurgitation. A frequent cause of VPI is congenital cleft palate, but otolaryngologists sometimes encounter iatrogenic VPI after surgery. Treatment of VPI with prostheses is often successful but not always well tolerated. Many surgical procedures have been proposed to correct palatal length or to enlarge the posterior pharyngeal wall. We report two cases in which autologous costochondral cartilage was used as implant augmentation. This approach is indicated and efficient when the velopharyngeal deficit is less than 5 mm. An autologous costochondral cartilage implant procedure is safe and reversible and can be expected to incite minimal host reaction.
