Measuring Effectiveness in Sleep Apnea Surgery - Full Text View

Sponsor:	University of California, San Francisco
Information provided by:	University of California, San Francisco
ClinicalTrials.gov Identifier:	NCT00518128

Purpose

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.

Arms	Assigned Interventions
Active Comparator: 1 Surgical OSA Treatment Group: Moderate to Severe OSA patients who are unable to tolerate PAP (Positive Airway Pressure) and elect to proceed with surgical treatment (surgical cohort).	Procedure: Surgical OSA treatment uvulopalatopharyngoplasty +/-tonsillectomy, genioglossus advancement, and hyoid suspension Other Name: UPPP, GA hyoid myotomy and suspension
Active Comparator: 2 Positive Airway Pressure Therapy Comparison Group: Moderate to Severe OSA patients who tolerate PAP (Positive Airway Pressure).	Procedure: Positive Airway Pressure Therapy Continuous positive airway pressure for treatment of obstructive sleep apnea Other Name: CPAP

Detailed Description:

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.
