Patel J, et al. - Researchers conducted this retrospective chart review to assess treatment outcomes of upper airway stimulation (UAS) in obstructive sleep apnea (OSA) individuals based on patient age, gender, and preoperative disease severity. Participants in the study were patients undergoing UAS from 2014 to 2018 at a tertiary care center. One hundred forty-five patients underwent UAS at the institution with a mean age of 61.7 ± 11.5 years, mean BMI of 29.1 ± 3.9 kg/m², and mean preoperative AHI of 34.1 ± 18.2 events/hour. While the overall OSA population showed substantial postoperative reduction in AHI with UAS, patients aged ≥ 65 years were less likely than their younger counterparts to have an initial response to treatment. After UAS, a higher proportion of elderly individuals and those with profound OSA had residual moderate disease (AHI > 15).
