The best treatment for OSAS is nasal continuous positive airway pressure (nCPAP).
nCPAP
For nCPAP therapy, a machine supplies a stream of air via a mask which fits over the nose and the air pressure keeps the throat open during the night.
Oral
appliances
Oral appliances can be used to help enlarge the airways.
These devices are less effective than nCPAP but can be better accepted by patients.
