Borderline cases of velopharyngeal insufficiency were treated with homologous cartilage implants. The selection of patients and technique for this procedure are described. Videonasopharyngoscopy was used to identify a specific location on the posterior pharyngeal wall for the implant. A small cube of homologous cartilage was implanted in the selected site in order to achieve adequate closure. The preliminary nasopharyngoscopic and speech evaluation results in 10 patients, who were followed every 3 months for at least 1 year, are reported. Hypernasality and audible nasal emission were eliminated. The displacement and reabsorption of the implants that occurred was minimal and did not affect velopharyngeal closure. Homologous cartilage, which is inexpensive and easy to obtain, appears to be a good option for implantation in the posterior pharyngeal wall in borderline cases of velopharyngeal insufficiency.
腭咽闭合不全的临界病例采用同种异体软骨植入进行治疗。本文描述了该手术的患者选择及技术方法。采用鼻咽喉镜检查确定咽后壁上植入物的具体位置。将一小方块同种异体软骨植入选定部位以实现充分闭合。报告了10例患者的初步鼻咽喉镜检查及语音评估结果，这些患者每3个月随访一次，至少随访1年。高鼻音和可闻及的鼻漏气消失。植入物发生的移位和吸收极少，未影响腭咽闭合。同种异体软骨价格低廉且易于获取，似乎是腭咽闭合不全临界病例中植入咽后壁的良好选择。
