Pharyngeal flap is usually used for treatment of velopharyngeal insufficiency (VPI); it is bridged between the posterior pharyngeal wall and the soft palate traversing the central part of the velopharyngeal port. The aim of this study was to assess the efficacy of lateralization of the pharyngeal flap for treatment of VPI in patients with lateral velopharyngeal gap. Fifteen patients with VPI due to lateral velopharyngeal gap were subjected to closure of the gap by pharyngeal flap that was lateralized to fill the gap. Preoperative and postoperative assessment of velopharyngeal functions including flexible nasopharyngoscopy, auditory perceptual assessment (APA), and nasometric assessment were performed. Postoperatively, flexible nasopharyngoscopy showed complete velopharyngeal closure in all the patients, with significant improvement of speech parameters as measured by APA. Also, nasalance score showed significant improvement for oral and nasal sentences that was measured by nasometry. Lateralization of the pharyngeal flap for treatment of VPI in patients with lateral velopharyngeal gap is an effective method; it improves the velopharyngeal closure and the speech of the patients.
咽瓣通常用于治疗腭咽闭合不全（VPI）；它横跨腭咽口中央部分，连接咽后壁和软腭。本研究的目的是评估咽瓣侧向移位术治疗存在腭咽侧方间隙的VPI患者的疗效。15例因腭咽侧方间隙导致VPI的患者接受了咽瓣侧向移位术以封闭间隙。对腭咽功能进行了术前和术后评估，包括可弯曲鼻咽镜检查、听觉感知评估（APA）和鼻音测量评估。术后，可弯曲鼻咽镜检查显示所有患者腭咽完全闭合，APA测量的语音参数有显著改善。此外，鼻音测量显示经鼻音测量的口腔和鼻腔语句的鼻漏气分数有显著改善。咽瓣侧向移位术治疗存在腭咽侧方间隙的VPI患者是一种有效的方法；它改善了腭咽闭合及患者的语音。
