Assessment of a novel type of oral appliance for the treatment of severe obstructive sleep apnea syndrome: a case series

Aim: This study aimed to evaluate the respiratory parameters among patients diagnosed with severe obstructive sleep apnea (OSA) syndrome treated a novel design of an oral appliance (OA): lingual orthosis.Methods: A case series was conducted 11 suffering from OSA, apnea-hypopnea index (AHI) > 30 events/h. All underwent pre- and post-treatment overnight polysomnography were by physician based on indexes. selected had history nonadherence continuous positive airway pressure devices.Results: Before treatment, mean AHI sample 65.9 ± 30.5. After reaching optimal OA titration, (PSG) showed average 10.1 5.5 (p<0.001). There significant reduction in events that decreased 60.0 31.7 8.5 3.8 events/hour The minimal oxyhemoglobin saturation improvement after increasing 74.3 7.8 83.4 4.9 (p<0.05).Conclusion: Lingual orthosis effective resolving OSAS, showing satisfactory results within present sample. Further studies are needed order broaden knowledge regarding effectiveness this appliance.Uniterms: Sleep apnea, obstructive. Orthotic devices. Case reports.
