[Efficacy of velopharyngoplasty for treating obstructive sleep apnea hypopnea syndrome].
To investigate the indication, efficacy and influencing factors of velopharyngoplasty for treating of obstructive sleep apnea hypopnea syndrome (OSAHS). Thirty OSAHS patients were included in this study, all cases had velopharyngoplasty. The follow-up period was between 6 to 11 months; and a series of measurements parameters was analysed for thirty cases. When compared preoperatively and postoperatively, Apnea and hypopnea index (AHI) decreased from 54.6+/-18.3 to 25.3+/-9.5; and the Epworth sleep scale decreased from 16.5+/-4.8 to 5.2+/-4.1. According to related criterion in China, the effective rate was 70.0%. Velopharyngoplasty can upgrade the venlopalate and enlarge the space of the oropharynx by remodeling of soft palate, contraction of scar and removal of the tonsils.
