This prospective study was done to determine whether a new cleft palate repair utilizing uvular transposition improved speech outcome as measured objectively by a speech pathologist. In the uvular transposition procedure, the palate was lengthened with tissue from the uvula by a double-opposing Z-plasty; an intravelar veloplasty was performed, and two-thirds of the mass of the uvula was transposed to the nasal surface of the soft palate. This procedure facilitates velopharyngeal closure by significantly lengthening the palate, anatomically reconstructing the muscles of the palate, and decreasing the palatal excursion necessary to achieve closure. Sixty-two children with a cleft palate were treated with this procedure performed by the senior surgeon between the years of 1988 and 1995. These children were then enrolled in cleft lip and palate clinic at age 2 to 3 years and blindly evaluated yearly by a single speech pathologist who specialized in pediatric speech pathology. Postoperative clinical follow-up ranged from 36 to 112 months (mean, 56.8 months). Perceptual nasal emission was found to be normal in 59 of the 62 patients (95 percent). Nasometry was performed in all 62 of these patients, and the mean score was 15.7 percent, well within the accepted normal range of 25 or less at our institution. Only two of these children (3 percent) required a pharyngeal flap for velopharyngeal insufficiency. These findings suggest that the uvula transposition cleft palate repair may result in good normalization of speech with negligible rates of velopharyngeal insufficiency.
本前瞻性研究旨在确定一种利用悬雍垂移位的新型腭裂修复术是否能改善语音结果,该结果由言语病理学家进行客观测量。在悬雍垂移位手术中,通过双反向Z形皮瓣术利用悬雍垂组织延长硬腭;进行腭内腭成形术,并将三分之二的悬雍垂组织转移至软腭的鼻面。该手术通过显著延长硬腭、从解剖学上重建腭部肌肉以及减少实现腭咽闭合所需的腭部移动,促进腭咽闭合。1988年至1995年间,资深外科医生对62例腭裂患儿实施了该手术。这些患儿在2至3岁时进入唇腭裂诊所,并由一位专门从事儿童言语病理学的言语病理学家每年进行盲法评估。术后临床随访时间为36至112个月(平均56.8个月)。62例患者中有59例(95%)的感知性鼻漏气正常。对所有62例患者均进行了鼻音测量,平均得分为15.7%,在本机构25%或更低的公认正常范围内。这些儿童中只有2例(3%)因腭咽功能不全需要进行咽瓣手术。这些发现表明,悬雍垂移位腭裂修复术可能会使语音良好地恢复正常,且腭咽功能不全的发生率可忽略不计。
