Abstract

|
|
|
Mandibular advancement devices (MAD) are therapeutic options for obstructive sleep apnea (OSA). The aim of study was to investigate treatment outcomes of before and after insertion of MAD in OSA patients. We retrospectively selected a total of 13 patients who were diagnosed with OSA syndrome. All sleep-related parameters including apnea-hypopnea index (AHI), oxygen desaturation index (ODI), wake after sleep onset (WASO), total arousal were measured by before and after MAD. The use of MAD proves to be efficient in reducing snoring, apnea-hypopne index (17.2±14.6 vs 20.9±14.6), WASO (27.4±28.8 vs 47.9±43.6 ), oxygen desaturation index (9.0±11.6 vs 16.4±11.7), stage N3 (54.8±45.2 vs 36.6±22.0), REM sleep times (73.3±19.4 vs 66.0±31.0) and increases sleep efficiency (92.6±6.6 vs 87.2±11.2). The decreases in apnea index based on a reduction in the overall and supine AHI values after MAD therapy were significantly greater for the positional OSA than nonpositional OSA patients. The use of MAD proves to be efficient in snoring, WASO, sleep efficiency, reduced AHI and associated with good compliance of patients.
