Prediction of oral appliance treatment outcome in XXXX : a preliminary study.

@entity1 @entity27 @entity1697
OBJECTIVE: Predictors of treatment outcome of @entity1697 ( @entity1697 ) in @entity1 with @entity27 ( @entity27 ) are not known. There is a pressing need for simple, clinically useful tools to predict treatment outcome. This study aimed to identify predictors of successful OA therapy for @entity27 , including evaluation of pharyngeal morphology, which can be measured during routine examination by an otorhinolaryngologist. METHODOLOGY: This was a prospective study of 26 @entity27 @entity1 treated with @entity1697 . A favourable outcome was obtained in 14 @entity1 (responders) but not in 12 @entity1 (nonresponders). The baseline @entity1 characteristics and polysomnography and rhinopharyngeal findings were analysed. RESULTS: Body mass index (BMI) was significantly lower in responders versus nonresponders (23.6    2.8 vs. 27.9    4.7 kg/m2; p < 0.05). Pharyngeal morphology, age, sex and nasal resistance did not differ between the groups. Multiple regression analysis showed that BMI was a significant predictor of improvement in the apnoea/hypopnoea index after OA treatment (p < 0.05). CONCLUSION: Here we demonstrated that BMI is a favourable predictor of OA treatment outcome in @entity27 @entity1 . Among the @entity27 @entity1 , responders had wider retroglossal spaces than nonresponders.
