Objective:
To investigate the indication, efficacy and influencing factors of velopharyngoplasty for treating of obstructive sleep apnea hypopnea syndrome (OSAHS).
Method:
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.
Result:
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%.
Conclusion:
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.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
