Of those with obstructive sleep apnea, unique clinical and demographic characteristics were identified in those who underwent soft tissue and orthognathic sleep surgery. Trends in palate-related surgery, as well as the proportion that was female, were examined over time.
Objective
To identify clinical and demographic characteristics of adults with obstructive sleep apnea (OSA) undergoing soft tissue and orthognathic sleep surgery, assess temporal trends in surgery type and proportion of women undergoing surgery, and provide clinical perspective before wide-spread implementation of hypoglossal nerve stimulation (HGNS).
Methods
In a retrospective cohort study, adults diagnosed with OSA from 2009 to 2016 were identified in a large integrated healthcare system. Characteristics between cohort members who did and did not undergo sleep surgeries were compared. Multivariable logistic regression models examined associations of different characteristics with whether surgery was performed.
Results
Of 172,216 adults with OSA, 2,262 (1.3%) underwent sleep surgery during 2009–2017. The most common sleep surgery was palate surgery (56.9%), which decreased proportionately over time. In multivariable analysis, older age and obesity were associated with lower odds of undergoing surgery. Those who underwent tonsillectomy and adenoidectomy were more likely to have larger tonsils and not require additional surgery, whereas tongue reduction recipients were more likely to have severe OSA and require multiple surgery types. The proportion of women undergoing surgery increased over time (p < 0.001 from trend test).
Conclusion
Clinical and demographic characteristics associated with soft tissue and orthognathic sleep surgery were identified in a large adult cohort prior to widespread implementation of HGNS. An increase in sleep surgery among women and a decrease in palate surgery over time were observed. The findings provide clinical perspective on sleep surgery performed prior to implementation of HGNS and may inform future studies examining its associations with patient characteristics.
