Improvements in sleepiness, quality of life, and respiratory outcomes are observed with 5 years of UAS. Serious adverse events are uncommon. UAS is a nonanatomic surgical treatment with long-term benefit for individuals with moderate to severe OSA who have failed nasal continuous positive airway pressure.
Post-Approval Upper Airway Stimulation Predictors of Treatment Efficacy in the ADHERE Registry

European Respiratory Journal 2018; DOI: 10.1183/13993003.01405-2018
Conclusion: In a large multicenter international registry, UAS is an effective treatment option with high patient satisfaction and low adverse events. Increasing age and reduced BMI are predictors of treatment response.

AHI reduction and therapy usage were found to be somewhat higher among patients aged ≥65 years who were treated with UAS. Surgical complications were low, in contrast to traditional sleep surgery.

While both traditional surgery and HNS are effective treatments for patients with moderate to severe OSA with CPAP intolerance, our study demonstrates that HNS is “curative” in normalizing the AHI to <5 in the majority of patients. For select patients, HNS therapy provides excellent objective improvement in outcome measures.
