Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There are two interventions (CPAP and surgery).
CPAP: Brad of ResMed-- S8 autoset Spirit in automatic positive airway pressure model. The participants put on the facial mask when sleeping, open the power of machine and the machine will start to work and automatically give the postitive pressure. Duration: 4 to 8 hours a day for 3 months
Surgery: Uvulopalatopharyngoplasty, occur once. Approximate duration of uvulopalatopharyngoplasty: 1 hour
All participants undergo only one intervention. Either CPAP or surgery treatment will be chosen by each participant.
Intervention code [1] 286212 0
Treatment: Surgery
Intervention code [2] 286213 0
Treatment: Devices
Comparator / control treatment
The control group means we plan to recruite subjects who have snore but no obstructive sleep apnea during sleep. We would like to know the differences between thes two groups, snore without obstructive sleep apnea and snore with obstructive sleep apnea. There is no control group for treatment.
