The efficacy of a modified mandibular advancement device for OSA treatment in a group of adult patients

Objective: The Mandibular Advancement Device (MAD) is actually recommended for the treatment of Obstructive Sleep Apnea (OSA) with mild or moderate severity. The present study evaluated the effects of a fully customizable MAD-type device (It Makes You Sleep, IMYS), in patients with moderate-to-severe OSA. Methods: Twenty-nine patients (15 men and 14 women; mean age 62, SD +/- 10 years) were retrospectively enrolled. Home Sleep Apnea Testing;(HSAT) was performed for all patients at baseline (T0) and after three months (T1) of IMYS therapy. The analyzed respiratory parameters were: Apnea-Hypopnea Index (AHI), Oxygen Desaturation Index (ODI), Minimum Oxygen Saturation (minSO2) and Medium Oxygen Saturation (medSO2). Results: From T0 to T1, a significant reduction of AHI and ODI was reported, as well as a significant increase of minSO2 and medSO2. Conclusion: The IMYS device could be an effective MAD appliance for treating moderate-to-severe OSA.
