Before you do surgery (non-reversible) you should consider this. There really is a better way to deal with sleep apnea than CPAP or surgery.  I spent 4 years studying sleep apnea and I believe that the root cause is due to the attenuation of the signal from the brain to the diaphragm muscles when the sleeper enters stage II sleep.  This un-intended side-effect of the "reduction of muscle tonus" that occurs during this transition causes breathing to stop.  Then, when the CO2 level gets too high, the sleeper makes a rapid inhalation DRAGGING the soft tissue into the airway, obstructing it and waking them up.  The reduction of the signal from the brain is causing the problem.
So... I found this herbal combination product that INCREASES the signal and keeps the breathing going.  This addresses the root cause so you don’t make a rapid inhalation and drag the sagging tissues into the airway.  The stuff is called Sleep Apnea Relief and I buy it from Nature's Rite.  I've been using it for 4 years and it is really great.  So you don't have to use CPAP.  I just wanted to let you know.
