Mild to Moderate Sleep Apnea Treatment Options: CPAP, MAD, Surgery & Nasal Stent Comparison Guide 2025
Struggling with obstructive sleep apnea disrupting your nights? Discover which treatment—CPAP machines, mandibular advancement devices, surgical intervention, or innovative intranasal stents—delivers the best results for your sleep breathing disorder. Real clinical data, authentic patient experiences, and evidence-based comparisons to help you breathe freely again.
When diagnosed with mild to moderate obstructive sleep apnea (OSA), the treatment landscape can feel overwhelming. With an apnea-hypopnea index (AHI) between 5-30 events per hour, you're caught between multiple therapy paths—each promising relief from snoring, interrupted breathing, and daytime exhaustion. This comprehensive comparison examines four primary treatment modalities: continuous positive airway pressure (CPAP), mandibular advancement devices (MAD/oral appliances), surgical interventions, and the emerging category of nasal stent therapy. Unlike generic overviews, we've compiled real-world effectiveness data, long-term compliance statistics, and authentic user experiences to guide your decision.
📊 Key Finding from Clinical Research
A 2023 meta-analysis published in the Journal of Clinical Sleep Medicine found that while CPAP reduces AHI more effectively, mandibular devices achieve similar health outcomes due to significantly higher compliance rates (5.7 hours/night vs 3.8 hours/night for CPAP). For mild-to-moderate cases, the treatment you'll actually use consistently often outperforms the one that's theoretically superior.
Why Treating Mild Sleep Apnea Matters
Even "mild" cases carry significant health risks when left untreated
During apneic episodes, blood oxygen levels can plummet below 90%, forcing your heart to work harder and triggering partial brain awakenings too brief to remember—yet profoundly affecting sleep quality and long-term cardiovascular health.

CPAP Therapy: The Gold Standard Examined
Continuous positive airway pressure remains the first-line recommendation for moderate-to-severe obstructive sleep apnea. The mechanism is straightforward: a bedside machine delivers pressurized air through a mask, creating a pneumatic splint that physically prevents airway collapse. When used correctly, CPAP effectively eliminates apneic events in the vast majority of patients.
However, the clinical reality reveals a significant gap between efficacy (how well it works when used) and effectiveness (real-world outcomes including compliance). Research published in the American Journal of Respiratory and Critical Care Medicine consistently shows that 30-50% of prescribed CPAP users abandon therapy within the first year, citing mask discomfort, claustrophobia, dry mouth, skin irritation, and disruption to intimacy.
Proven Efficacy
Reduces AHI by over 90% in compliant users. Decades of research support cardiovascular and cognitive benefits when used consistently.
Compliance Challenge
Only 49% maintain regular use after 6 months. Average nightly use of 3.8 hours falls short of the recommended 7+ hours.
Power Dependent
Requires electricity or battery backup. Travel CPAP units exist but add complexity and cost to trips.
Ongoing Costs
Mask replacements, filters, and hose cleaning supplies add €150-€400 annually beyond initial device investment.
Clinical Insight
For patients with mild OSA (AHI 5-15), a 2008 systematic review in the journal Sleep found that CPAP did not significantly improve objective sleepiness, blood pressure, or quality of life compared to placebo—challenging the assumption that CPAP benefits all severity levels equally.
Mandibular Advancement Devices: The Comfortable Alternative
Oral appliances, particularly mandibular advancement devices (MADs), have emerged as a first-line treatment option for mild-to-moderate OSA. These custom-fitted devices resemble sports mouthguards and work by repositioning the lower jaw forward during sleep, which enlarges the upper airway space and reduces the likelihood of tissue collapse.
The mechanism involves more than simple jaw advancement. Research in Clinical Otolaryngology demonstrates that MADs also increase oropharyngeal volume, reduce tongue retraction, and stiffen the pharyngeal walls—providing multi-level airway improvement through a single, non-invasive device.
Superior Comfort
No masks, hoses, or machines. Most users adapt within 2-3 weeks with minimal side effects.
Travel Ready
Fits in a small case, requires no power, and clears airport security without documentation.
Silent Operation
No machine noise to disturb partners. Enables spontaneous intimacy without setup.
High Compliance
84% of users maintain therapy at 6 months—nearly double the CPAP compliance rate.
A landmark 10-year follow-up study comparing MAD and CPAP therapy found both treatments showed significant improvement in AHI, oxygen saturation, and quality of life measures. Notably, despite CPAP achieving slightly lower AHI values, no difference was observed in long-term daytime sleepiness improvement between the treatments—suggesting that higher MAD compliance compensates for the modest efficacy gap.
Potential drawbacks include temporary jaw discomfort during adaptation, possible tooth movement with long-term use, and reduced effectiveness in patients with severe OSA or high BMI. Custom-fitted devices from sleep dentists cost €500-€2,000, though over-the-counter options exist at lower price points with variable effectiveness.
Surgical Interventions: When Anatomy is the Problem
For patients with specific anatomical abnormalities contributing to airway obstruction—enlarged tonsils, deviated septum, retrognathia (receding jaw), or excessive soft palate tissue—surgical correction may offer a permanent solution. However, surgery is typically considered salvage therapy after conservative treatments have failed.
UPPP Surgery
Uvulopalatopharyngoplasty removes excess throat tissue. Success rate approximately 33% for AHI reduction. Often requires additional procedures.
MMA Surgery
Maxillomandibular advancement repositions both jaws forward. Most effective surgical option (85%+ success) but involves significant recovery.
Inspire Implant
Hypoglossal nerve stimulation uses a pacemaker-like device. 72-75% surgical success rate at 5 years. Requires ongoing follow-up.
Nasal Surgery
Septoplasty, turbinate reduction address nasal obstruction. Often combined with other procedures. Improves CPAP tolerance.
The Inspire hypoglossal nerve stimulator represents a significant advancement in surgical OSA treatment. Clinical data from the STAR trial shows AHI reduction from an average of 46 to 4.6 events/hour in responders, with improvements maintained at 5-year follow-up. However, strict candidacy criteria (BMI ≤32, no complete concentric palate collapse) exclude many patients, and approximately one-third of implant recipients don't achieve target AHI reduction.
Important Consideration
Surgical outcomes are highly dependent on proper patient selection and surgeon expertise. A comprehensive drug-induced sleep endoscopy (DISE) is typically required to identify the specific site(s) of airway collapse before recommending surgical intervention.
Nasal Stent Therapy: The Emerging Innovation
A discreet, non-invasive approach addressing airway obstruction at its source
The intranasal stent represents a fundamentally different approach to treating sleep-disordered breathing. Rather than pushing air through obstruction (CPAP), repositioning anatomy (MAD), or surgically removing tissue, nasal stents create a physical air channel that remains open regardless of muscle relaxation or sleep position.
The Back2Sleep device—a CE-certified medical nasal stent developed over 10 years of research—extends from the nostril to the soft palate (approximately 7-9cm depending on anatomy). This positioning addresses the velopharynx, where obstruction commonly occurs, while maintaining natural breathing patterns without forced air pressure.
📊 Clinical Evidence: Nastent/Back2Sleep Studies
A peer-reviewed study of nasal airway stent efficacy demonstrated:
- REI reduction: 22.4 ± 14.1 → 15.7 ± 10.4 events/hour (p<0.01)
- Lowest SpO2 improvement: 81.9% ± 7.5 → 86.6% ± 4.8 (p<0.01)
- Snoring reduction: 70-85% from first night of use
- Adaptation timeline: 3-5 nights for most users
Note: 5 of 23 study subjects discontinued due to initial discomfort—highlighting that this solution, like all treatments, requires an adjustment period.

How the Nasal Stent Addresses Sleep Apnea
Real Experiences from Verified Users
Authentic testimonials from people who've transformed their sleep quality
"My AHI was at 27 and I've been using CPAP for 10 years. The machine was reliable but I hated traveling with it. Back2Sleep gives me freedom I haven't had in a decade. My wife can finally sleep without the constant humming."
"Efficient—my wife thanks you. No more separate bedrooms. The first few nights felt strange, like wearing contact lenses for the first time, but by day 4 I barely noticed it. Now I can't imagine sleeping without it."
"I travel between Osaka and Tokyo by Shinkansen constantly. Before, I couldn't sleep on trains—too embarrassed about my snoring. Now I sleep whenever I want. My concentration while driving has improved dramatically."
"At first, I didn't particularly like the product—I suffered from a runny nose and discomfort. But the more I used it, the more I started to trust it. Now I'm not conscious of it at all. Give it the full adaptation period."
"My partner wanted to sleep in separate rooms because of my snoring. That was the wake-up call. After trying the nasal stent, I measured with SnoreLab app—85% reduction in snoring from the very first night."
"My own snoring used to wake me up multiple times per night. I had what they call 'hidden nasal congestion'—fine during the day but blocked at night. Morning fatigue is gone. I feel like a different person."
What to Expect: The Adaptation Journey
Understanding the realistic timeline helps set appropriate expectations
Initial Awareness
You'll feel the presence of the stent. Some users experience mild nasal irritation or increased mucus production—this is normal. Snoring reduction is often noticeable immediately to partners.
Adjustment Phase
Similar to contact lens adaptation, discomfort diminishes significantly. Your body begins accepting the device as normal. Finding your correct size during this period is crucial.
Natural Integration
Most users report forgetting the stent is present. Sleep quality improvements become apparent: less morning grogginess, improved daytime alertness, reduced dry mouth.
Full Benefit
Optimal results achieved. Partners confirm sustained snoring elimination. Many users report not wanting to sleep without it. Time to transition to regular monthly supplies of your confirmed size.
Pro Tip from Long-Term Users
The Starter Kit includes four sizes (S, M, L, XL) specifically because finding the right fit is essential. Start with the size that feels comfortable during insertion—if snoring persists, move to the next length. Proper sizing balances effectiveness against comfort.

Choosing Your Treatment: A Decision Framework
The optimal sleep apnea treatment depends on individual factors including OSA severity, anatomy, lifestyle, travel frequency, partner considerations, and personal preferences. Use this framework to guide your decision:
Choose CPAP If...
You have moderate-to-severe OSA (AHI >15), tolerate masks well, rarely travel, and prioritize maximum AHI reduction over convenience. Insurance often covers devices.
Choose MAD If...
You have mild-to-moderate OSA, adequate dental health, prefer silent/portable solutions, and can invest in custom fitting from a qualified sleep dentist.
Choose Surgery If...
You have identified anatomical obstruction, failed conservative treatments, meet candidacy criteria, and prefer a potentially permanent (though not guaranteed) solution.
Choose Nasal Stent If...
You have mild-to-moderate OSA, travel frequently, value simplicity, want to try treatment before larger investments, or need CPAP alternative for trips.
💡 Combination Approaches
Many patients successfully combine treatments: using CPAP at home while traveling with a nasal stent, or combining positional therapy with an oral appliance. Discuss multi-modal approaches with your sleep specialist to find the optimal strategy for your specific situation.
