A retrospective cohort study evaluated a clinical staging system to predict response to hypoglossal nerve stimulation (HGNS) in obstructive sleep apnea patients using neck circumference, BMI, apnea-hypopnea index (AHI), and comorbidity burden. Involving 119 patients from Washington University, the cohort displayed a 69.7% response rate to HGNS, with specific baseline factors linking to improved outcomes. The findings emphasize the need for further validation due to inherent limitations and underscore the potential to better inform patients regarding treatment expectations.
