Oral negative-pressure therapy (OPT) provides a non-invasive, mask-free option for obstructive sleep apnea patients with poor CPAP adherence. A meta-analysis of published studies showed a 42.6% reduction in mean apnea–hypopnea index, with a moderate effect size and low heterogeneity, supporting OPT as a potential alternative for selected patients.

Meta-Analysis Shows Moderate AHI Reduction in OSA
Oral Pressure Therapy (OPT) in Obstructive Sleep Apnea
MRI-based evaluation of OPT demonstrated significant anatomical airway changes in obstructive sleep apnea responders. OPT enlarged the retropalatal airway through anterior displacement of the soft palate, resulting in marked apnea–hypopnea index reduction. These mechanistic findings support OPT as a targeted, anatomy-driven alternative for selected patient's intolerant of CPAP.

Successful OSA Symptom Control - iNAP
Mandibular advancement oral appliance therapy provided effective symptom control in a CPAP-intolerant obstructive sleep apnea patient. Clinical evidence shows meaningful reductions in apnea severity, improved daytime symptoms, and high long-term adherence. Despite less AHI reduction than CPAP, superior nightly usage supports oral appliances as a practical alternative for selected OSA patients.

Single-Night Feasibility Study of Mask-Free Therapy
A single-night feasibility study evaluated mask-free intraoral negative-pressure therapy in obstructive sleep apnea patient's intolerant to CPAP. Results demonstrated significant reductions in apnea–hypopnea index, improved oxygenation, and enhanced sleep continuity. Rapid polysomnography-based assessment enabled early responder identification, supporting oral negative-pressure therapy as a practical, non-invasive alternative for selected patients.
