0565 Impact on Oral Myofunctional Therapy to Treat The Patients with Moderate to Severe Obstructive Sleep Apnea

Le résumé fourni par la source

Current literature demonstrated oral myofunctional therapy (MFT) decreased apnea hypopnea indices (AHI) by 50% in middle aged patients (44.5 ± 11.6 years old) with moderate obstructive sleep apnea (OSA), however few studies was reported in elder patients with moderate to severe OSA. Twenty eight Japanese patients (19 males and 9 females) with moderate to severe OSA treated with continuous positive airway pressure (CPAP) or oral appliance (OA) for more than 6 months were included and MFT were performed 3 times a day for 6 months with CPAP or OA during sleep. The patients were educated MFT by dentists, described training diary, tongue pressures were calculated and checked their MFT pre, 2, 4 and 6 months after starting FMT with disposable tongue pressure measurement device (JMS, Japan). Polysomnography was studied before and after FMT without CPAP or OA. Those ages were 71.0 ± 7.5 years old and body mass indices were 23.6 ± 2.4 Kg/m2. The previous AHI were 34.7 ± 2.5 and AHI did not change significantly with CPAP or OA. The pre and post MFT AHI decreased from 36.2 ± 2.5 to 31.9 ± 2.5, p=0.025. Epworth Sleepiness Scale decreased from 7.5 ± 4.0 to 6.0 ± 3.5, p=0.013. Tongue pressure increased from 37.4 ± 8.5 to 42.7 ± 9.1kPa, p < 0.001, neck circumference decreased from 38.1 ± 3.8 to 37.2 ± 3.4cm, p=0.024. Body weight and waist circumference did not change significantly. MFT might support the treatment to elder patients with moderate to severe OSA. Support (If Any)
