Brief Summary:
The goal of this research is to improve our understanding of the effectiveness of surgical OSA treatment by evaluating its impact on these health-related and functional outcomes and comparing these effects to the changes in respiratory physiology achieved after surgery. To achieve this goal, we will examine key health-related (C-reactive protein, homocysteine, leptin, the homeostasis model of insulin resistance, and heart rate variability) and functional (sleep-related quality of life and vigilance) measures among a surgical group of OSA patients who do not tolerate non-surgical treatment (positive airway pressure, PAP) and a comparison group of matched OSA patients who tolerate PAP.

The goal of this research is to improve our understanding of the effectiveness of surgical OSA treatment by evaluating its impact on these health-related and functional outcomes and comparing these effects to the changes in respiratory physiology achieved after surgery. To achieve this goal, we will examine key health-related (C-reactive protein, homocysteine, leptin, the homeostasis model of insulin resistance, and heart rate variability) and functional (sleep-related quality of life and vigilance) measures among a surgical group of OSA patients who do not tolerate non-surgical treatment (positive airway pressure, PAP) and a comparison group of matched OSA patients who tolerate PAP. We propose to measure the impact of surgical OSA treatment on these health-related and functional outcomes measures with the following three analyses: (1) to assess the changes seen with surgical treatment; (2) to compare changes seen with surgical and PAP treatment; and (3) to evaluate the association between changes in respiratory patterns during sleep and changes in health-related and functional outcomes measures for both surgical and PAP treatment.
