Qian Y, Zou J, Xu H, et al. - In the present study, the researchers sought to explore the correlation between upper airway surgery and changes of cardiological metabolic biomarkers and the overall cardiovascular risk in obstructive sleep apnea (OSA) and to define factors related to better cardiovascular outcomes. The sample consisted of 161 individuals with newly diagnosed OSA who had classical or modified uvulopalatopharyngoplasty with or without genioglossus advancement and hyoid suspension. OSA-related upper airway surgery was linked to improvements in cardiological metabolic biomarker levels and the overall cardiovascular risk, particularly in patients with both OSA and metabolic disorders. After surgery, the changes in biomarker levels can be related to improved oxygen saturation.
