Objective: The purpose of this study is to examine what demographic factors correlate with greater rates of upper airway stimulation adherence and efficacy.

Study Design: Case control study


Upper airway stimulation (UAS) is emerging as an effective procedure for select patients with obstructive sleep apnea. As initially studied, this procedure is reserved for those exhibiting body mass index (BMI)


We queried a single surgeon’s database of UAS cases, totaling 97 at the time of study. The electronic medical record (EMR) was queried for each patient and pertinent demographics were recorded. We began by defining cohorts: super-adherers were those with greater than 6 hours of nightly device use; non-adherers less than 4. Super-responders had a post-operative AHI and ESS less than 10, and greater than 80% decrease in AHI. Non-responders had an AHI greater than 20 and less than 50% decrease. Super-performers met both super-adherer responder criteria, while non-performers similarly met both negative criteria.


Overall, 97 patients underwent hypoglossal nerve stimulation with an average AHI reduction of 67.1%, and 6.2 hours of nightly adherence. 11 patients were defined as super-performers, and 3 as non-performers. 20 patients were super responders vs 11 non-responders. 49 were super adherers vs 34 non-adherers. P-values for various categories will be displayed in Table 1, no difference was found between the groups as age, BMI, sex, pre-op AHI, and pre-op VOTE score were examined.


Upper airway stimulation is an effective treatment for patients intolerant of CPAP. In this review there were no statistically significant differences found between the best and lowers performing patients in terms of baseline characteristics.
