Brief Summary
Hypothesis:Pharyngeal surgery (UPPP) reduces significantly the nightly respiratory breathing pauses (apnoeas-hypopnoeas) and improves the daytime symptoms compared to expectancy for 6 months in patients with OSAS. Background: Obstructive sleep apnea syndrome (OSAS) is associated with an increased risk of poor sleep quality, excessive daytime sleepiness and prolonged reaction time, which can elevate the risk for traffic accidents. Increased morbidity and three to four times increased mortality in these patients are well documented, mainly in the cardiovascular field. Pharyngeal surgery, i.e. uvulopalatopharyngoplasty (UPPP) opens up the airway and was the predominant treatment for OSAS worldwide before continuous positive airway pressure (CPAP) devices became widely available in the 1990s. Since then, the main treatment for OSAS has been CPAP, but an increasing number of patients are also treated with mandibular retaining device (MRD). UPPP as treatment for OSAS has been performed for 30 years. The evidence-grade for the efficacy has so far been very low, and the side-effects and complication rate has raised the question whether there is a place for surgical treatment of OSAS. However, the compliance for CPAP and dental devices are quite low (50-60%), leaving a lot of patients untreated if surgery is not offered. RCT UPPP is still missing and called for.

Outcome Measures
Primary Outcomes (1)
Changes in apnea-hypopnea index
Apnea-hypopnea index (AHI) is the number of apneas or hypopneas per sleep hour. Polysomnography (PSG) is the Golden standard to use when measuring the AHI. PSG is the method we are using
6 months and 2 years
Secondary Outcomes (1)
Changes in Epworth sleepiness scale
6 months and 2 years
Other Outcomes (21)
Changes in Oxygen desaturation index
6 months and 2 years
changes in blood samples
6 months 2 years
changes in score of SF 36 quality of life questionnaire
6 months and 2 years
- +18 more other outcomes
Study Arms (2)
Uvulopalatopharyngoplasty
ACTIVE COMPARATOROne arm is Uvulopalatopharyngoplasty(intervention group of 32 patients), one arm is expectancy (control group of 33 patients). After six months the controls have delayed surgery and then both groups are followed for two years
Control
ACTIVE COMPARATORAfter six months the controls have delayed surgery then are followed for 2 year
Interventions
Uvulopalatopharyngoplasty: Resection of the soft palate 3 mm and tonsillectomy, amputation of the uvula to approx 1 cm, single sutures of the posterior pillar to the anterior pillar and of the soft palate.
