The conventional sphincteric pharyngoplasty does not achieve velopharyngeal competence in certain cases because of the intrinsic deficiency of the technique. A modified palatopharyngeous flap operation was introduced and used as a secondary procedure for the correction of velopharyngeal incompetence in 15 cleft palate patients. The results showed that the lateral-to-lateral connection and the high attachment of the palatopharyngeal flaps can form a new velopharyngeal port that is easily closed by velar movement. The surgical result is satisfactory, as revealed by the speech intelligibility test, videofluoroscopy, and nasopharyngoscopy. The surgical technique is described and the importance of presurgical identification of velopharyngeal movements is stressed in this paper.
传统的括约肌咽成形术在某些情况下由于技术本身的缺陷无法实现腭咽闭合。本文介绍了一种改良的腭咽瓣手术,并将其作为15例腭裂患者腭咽功能不全矫正的二期手术方法。结果表明,腭咽瓣的侧向连接和高位附着可形成一个新的腭咽口,该口可通过软腭运动轻松闭合。语音清晰度测试、电视荧光透视检查和鼻咽镜检查结果显示手术效果令人满意。本文描述了手术技术,并强调了术前识别腭咽运动的重要性。
