Abstract

OBJECTIVE: The apnea-hypopnea index (AHI) quantifies obstructive sleep apnea (OSA) severity but has limited correlation with subjective symptoms and cardiovascular risk. Sleep parameters related to oxygenation status and hypoxic burden may offer utility as additional predictors of cardiovascular risk and the physiologic consequences of OSA. This study aims to assess the change in measures of oxygenation status following sleep surgery for OSA.

STUDY DESIGN: A retrospective cohort study.

SETTING: A single-institution tertiary care center.

METHODS: Patients who underwent hypoglossal nerve stimulator (HGNS) placement, expansion sphincter pharyngoplasty (ESP), or maxillomandibular advancement (MMA) for continuous positive airway pressure-intolerant OSA were included. The percentage of sleep time below SaO

RESULTS: A total of 219 patients were included (65% HGNS, 24% ESP, 11% MMA). The average decline in AHI and ESS was 11.9 events/h (standard deviation [SD] = 19.9, P <  .001) and 3.2 points (SD = 4.7, P <  .001), respectively. Among measures of sleep oxygenation, pT90 (11.5 → 8.9, P <  .001), oxygen desaturation index (27.1 → 15.1, P <  .001), and SpO

CONCLUSION: Upper airway surgery improves metrics of oxygen status in addition to the AHI. Changes in pT90 correlate with subjective symptoms of OSA per ESS, suggesting utility in capturing disease burden.
