Summary
A tongue-retaining device (TRD) significantly improved sleep apnea metrics in patients. This oral appliance effectively treated mild to severe obstructive sleep apnea (OSA), reducing oxygen desaturation events.
Area of Science:
- Sleep Medicine
- Respiratory Physiology
Background:
- Obstructive sleep apnea (OSA) is a common sleep disorder characterized by repeated airway collapse.
- Oral appliances are a treatment option for OSA, but their effectiveness varies.
- Tongue-retaining devices (TRDs) are a specific type of oral appliance designed to prevent tongue-based airway obstruction.
Purpose of the Study:
- To evaluate the efficacy of a tongue-retaining device (TRD) in patients with obstructive sleep apnea (OSA).
- To compare key sleep apnea respiratory parameters with and without TRD usage.
Main Methods:
- A study involving eight patients diagnosed with obstructive sleep apnea (OSA).
- Assessment of respiratory parameters including the 3+% oxygen desaturation index (ODI3), lowest percutaneous oxygen saturation (SpO2), and time spent with SpO2 < 90% under two conditions: baseline (TRD(-)) and with a TRD (TRD(+)).
Main Results:
- Significant improvements were observed in ODI3, lowest SpO2, and time spent with SpO2 < 90% when using the TRD (P < 0.01-0.05).
- Five patients (63%) experienced a >50% reduction in ODI3 from baseline.
- Six patients (75%) achieved an ODI3 of fewer than 10 events/hour with TRD use.
Conclusions:
- Tongue-retaining devices (TRDs) are effective in managing mild to moderate obstructive sleep apnea (OSA).
- TRDs demonstrate potential for effectively treating patients with more severe forms of OSA as well.
- Oral appliance therapy, specifically TRDs, offers a viable treatment strategy for a range of OSA severity.
