CPAP is the most established first-line treatment for obstructive sleep apnea (OSA), and for many people it works well once they find the right mask and pressure settings. But it isn’t the only option, and it doesn’t work equally well for everyone — some people can’t tolerate the mask or pressure long-term, and others see real but incomplete improvement even with consistent use. If that’s where you are, it’s worth knowing what the alternative and adjunct paths actually look like.
Oral appliance therapy
For mild to moderate OSA, or for people who can’t tolerate CPAP, a custom-fitted oral appliance — most commonly a mandibular advancement device (MAD) — is a well-established option. According to the American Academy of Sleep Medicine, these devices work by gently repositioning the lower jaw forward during sleep, which helps keep the airway more open. They’re generally less effective than CPAP for severe OSA, but for people who genuinely can’t stick with CPAP, an oral appliance that’s actually worn consistently often outperforms a CPAP machine that sits in the closet.
Positional therapy and weight-related factors
For people whose apnea is significantly worse lying on their back (positional OSA), devices or techniques that discourage back-sleeping can meaningfully reduce AHI (apnea-hypopnea index) in the right candidates, per guidance summarized by the Sleep Foundation. Separately, the National Heart, Lung, and Blood Institute notes that weight management, where excess weight is a contributing factor, can reduce OSA severity for some people — though it’s rarely a complete standalone fix for moderate-to-severe cases and works best alongside, not instead of, medically supervised treatment.
Surgical options for select cases
When CPAP and oral appliances aren’t enough, or aren’t tolerated, surgical approaches exist for carefully selected patients — typically after imaging and airway evaluation (such as drug-induced sleep endoscopy, or DISE) identify exactly where the airway is collapsing. These range from soft-tissue procedures like uvulopalatopharyngoplasty (UPPP) to more involved skeletal surgery like maxillomandibular advancement (MMA), which repositions the upper and lower jaw to enlarge the airway.
A useful illustration of both the potential and the limits of MMA comes from a small 2023 case series out of the University of Catania, published in the Journal of Personalized Medicine. Two men with severe OSA who hadn’t been able to tolerate CPAP — one with a pre-surgery AHI of 30 (after earlier procedures), another with an AHI of 51.8 after two years of CPAP failure — underwent MMA. Six months later, their AHI dropped to 13 and 8.8 respectively, both saw meaningful improvement in sleepiness scores and quality of life, but notably, neither reached an AHI below 5, meaning some residual sleep apnea remained even after major surgery (Stilo G, et al., J Pers Med, 2023). It’s a helpful reminder that surgery — like any single treatment — can substantially improve severe OSA without necessarily eliminating it entirely, and that “greatly improved” and “cured” aren’t the same thing.
Newer and adjunct approaches
Hypoglossal nerve stimulation (an implanted device that stimulates the airway muscles during sleep) has also gained traction for people with moderate-to-severe OSA who can’t use CPAP, per Mayo Clinic’s OSA treatment overview, and is generally considered after other options haven’t worked. Myofunctional therapy (targeted exercises for the tongue and airway muscles) and treating nasal obstruction are sometimes used as adjuncts alongside a primary treatment, rather than as standalone solutions for moderate-to-severe disease.
The bottom line
If CPAP alone isn’t fully controlling your apnea, or you can’t tolerate it, that’s a conversation to have with a sleep medicine specialist rather than a reason to just live with untreated OSA — there’s a real range of evidence-based alternatives and combination approaches, and the right one depends heavily on your specific anatomy, severity, and what a sleep study and airway evaluation show.
