PAP is the "gold standard" and the most effective therapy for obstructive sleep apnea (OSA), . . . A good sleep center will . . . improve the long term compliance to CPAP. . . . Surgical procedures for OSA are unpredictable and generally less effective than PAP. . . . Nasal reconstruction targets extra or distorted tissue in the nose that blocks the flow of air. The advantage of the nasal reconstructive surgery is that, even though it does little for treating sleep apnea itself, it might make a person better able to tolerate PAP treatment with a nasal mask.

Surgery for obstructive sleep apnea (OSA) is usually not done unless other treatments have failed or you are unable or choose not to use other treatments. . . . Experts generally suggest trying continuous positive airway pressure (CPAP) before considering surgery. . . . In adults, uvulopalatopharyngoplasty (UPPP) is the most common surgery used to treat sleep apnea. There is no clear research on how well UPPP works for sleep apnea. UPPP may stop snoring, but apnea episodes may continue.
So, after UPPP, you may not be able to use an APAP that uses snores to adjust therapy.
WebMD continues:
Limited research indicates that about 40% to 60% of people who have UPPP see an improvement in their symptoms.
Those are pretty lousy odds, in my book.
WebMD contiues:
You may still need other forms of treatment, including continuous positive airway pressure (CPAP), after surgery. You will need sleep studies after surgery to make sure periods of apnea do not continue or return.
My summary of the above is that nasal surgeries may help PAP therapy go better. Palate surgery may make it go worse and may make using an APAP impossible. Either way, you are still likely to need to keep using PAP therapy, depending on the results of the sleep studies that follow.

"If one were to select only young, otherwise healthy, nonobese, mildly apneic snorers with identifiable, correctable abnormalities (large tonsils, drooping palate, long uvula), success with UPPP and tonsillectomy, by any measure, might exceed 90% of patients. Contrarily, if one selected obese, severly apneic snorers with a bulky tounge, receding chin, and flabby narrowed hypopharngeal air passages, success with UPPP would be unlikely. Somewhere in between those two extremes falls the majority of snoring and sleep apneic patients. For them the probablility of success versus failure of UPPP is often unpredictable."--Snoring and Obstructive Sleep Apnea By David N. F. Fairbanks, Samuel A.
