With the exception of cases where a lesion creates a clearly identifiable and surgically removable anatomical obstacle on the upper air duct (tumors, cysts, hypertrophic tonsils, vegetations,...), currently the continuous positive air pressure is the treatment of choice.

Another promising way is prevention through specific mouth breathing treatment from the earliest age on.
