Trans-oral endoscopic cerclage pharyngoplasty for treatment of velopharyngeal insufficiency

摘要

Objectives: Velopharyngeal insufficiency (VPI) is a common problem after cleft palate repair, it leads to speech distortion with consequent affection of speech intelligibility. Many techniques have been used in the treatment of VPI with varying results and complications. The aim of this study was to evaluate the efficacy of trans-oral endoscopic cerclage pharyngoplasty in the treatment of VPI. Methods: Eighteen patients with hypernasality after palatoplasty were subjected to trans-oral endoscopic cerclage pharyngoplasty. Pre and postoperative evaluation of velopharyngeal function were performed by using auditory perceptual assessment, nasometric assessment, and flexible nasopharyngoscopy. Results: Significant postoperative improvement of speech parameters measured with auditory perceptual assessment were achieved, and the overall postoperative nasalance score was improved significantly for nasal and oral sentences. Also, flexible nasopharyngoscopy showed significant improvement of velopharyngeal closure. No marked postoperative complications were reported apart from throat pain and dysphagia that disappeared with time. Conclusions: Trans-oral endoscopic cerclage pharyngoplasty is an effective method for the treatment of VPI.
