The aim of the present study was to evaluate how the features of obstructive sleep apnoea (OSA) and the degree of mandibular advancement influence the outcomes of oral appliance therapy with a fully-customised mandibular advancement device (MAD) in an adult population. A total of 85 adult patients with mild to severe OSA were retrospectively selected. Polysomnography was taken before treatment and after 2 months treatment with overnight MAD. Treatment success was defined as a > 50% reduction in the Apnoea/Hypopnoea Index (AHI) with a residual AHI < 10. Binary logistic regression was used to evaluate the effects of AHI, oxygen desaturation index (ODI), gender and age on the success rate of MAD therapy. MAD therapy was successful in 77.7% of patients, and the ODI was a significant predictor of treatment success. OSA treatment with the MAD was successful in reducing the AHI in adult patients. An ODI value smaller than 33.3 was a significant predictor of treatment success.
Lo scopo del presente lavoro è stato quello di valutare in che modo le caratteristiche della sindrome delle Apnee Ostruttive del Sonno (OSA) ed il grado di avanzamento mandibolare influenzano i risultati della terapia con dispositivi di avanzamento mandibolare (MAD) individualizzabili in una popolazione adulta. Sono stati selezionati retrospettivamente 85 pazienti adulti con OSA da lieve a severa. È stata eseguita una polisonnografia pre-trattamento e dopo 2 mesi di terapia notturna con MAD. La terapia è stata definita di successo se ha comportato una riduzione dell’Indice di Apnea/Ipopnea (AHI) > 50% con un AHI residuo < 10. Una regressione logistica binaria è stata usata per valutare l’effetto di AHI, indice di desaturazione dell’ossigeno (ODI), sesso ed età sul tasso di suc-cesso della terapia con MAD. Tale trattamento ha avuto successo nel 77,7% dei pazienti, e l’ODI è risultato essere un predittore significativo della probabilità di successo della terapia. Il trattamento delle OSA con il dispositivo MAD utilizzato si è rivelato efficace nel ridurre l’AHI nei pazienti adulti. Un valore di ODI inferiore a 33,3 è indicativo della possibilità di successo del trattamento

Abstract
The aim of the present study was to evaluate how the features of obstructive sleep apnoea (OSA) and the degree of mandibular advancement influence the outcomes of oral appliance therapy with a fully-customised mandibular advancement device (MAD) in an adult population. A total of 85 adult patients with mild to severe OSA were retrospectively selected. Polysomnography was taken before treatment and after 2 months treatment with overnight MAD. Treatment success was defined as a > 50% reduction in the Apnoea/Hypopnoea Index (AHI) with a residual AHI < 10. Binary logistic regression was used to evaluate the effects of AHI, oxygen desaturation index (ODI), gender and age on the success rate of MAD therapy. MAD therapy was successful in 77.7% of patients, and the ODI was a significant predictor of treatment success. OSA treatment with the MAD was successful in reducing the AHI in adult patients. An ODI value smaller than 33.3 was a significant predictor of treatment success.File | Dimensione | Formato | |
