I have only heard of a few things that work with varying levels of invasiveness.

1: is if you are obese losing weight can reduce obstructive apnea.

2: if it is just the shape of your jaw, there are mouth pieces that you can wear at night that keep your jaw from falling, causing obstruction.

3: central positive air pressure or "CPAP" devices can push air into your lungs at night.

4: if your neck and throat area is just too muscular or fatty, there are surgeries to sculpt this. This is generally only in extreme scenarios.
