My son just had surgery for his sleep apnea. Is it normal for him to still snore after?

Wouldn't you like to know? says:

How “just’ is just? If he has some swelling in his throat, that may be obstructing his airway a bit, causing the snoring. I would assume that after it has gone down you should see a reduction. If it’s been a while, then you need to call the surgeon.
