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 SaO₂ 90% (pT90) was used to characterize oxygenation status. Wilcoxon signed-rank test compared changes in sleep metrics from preoperatively to postoperatively. Linear regression was performed to assess whether changes in pT90 were correlated with changes in AHI and Epworth Sleepiness Scale (ESS), respectively.

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 SpO₂ nadir (79.9 → 81.2, P = .03) improved significantly following surgery. On linear regression, changes in pT90 were significantly correlated with changes in AHI (β = 0.31, 95% confidence interval [CI] 0.18-0.45, P < .001) and ESS (β = .05, 95% CI 0.00, 0.09, P = .038), respectively.

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.

期刊介绍： Otolaryngology–Head and Neck Surgery (OTO-HNS) is the official peer-reviewed publication of the American Academy of Otolaryngology–Head and Neck Surgery Foundation. The mission of Otolaryngology–Head and Neck Surgery is to publish contemporary, ethical, clinically relevant information in otolaryngology, head and neck surgery (ear, nose, throat, head, and neck disorders) that can be used by otolaryngologists, clinicians, scientists, and specialists to improve patient care and public health.
