Can someone say what happens when you simply cut the mucocele "bubble"...

from my own experience there's more chance of the mucocele reforming again almost within a few hours that it not reforming. I've had six in the last 10 years. Two have been surgically removed (and one came back after surgery), the other went after surgery. Three have simply come and gone without treatment, they lasted no more than three months. One I did pierce and drain stayed for about five months and then it vanished never to return. I currently have another inside my mouth, which luckily is not too bothersome but I'm due to have it removed via surgery. It's been there for about four months now and goes up and down in size, so some days are better than others. I'm very tempted to pierce its quite deep inside the cheek tissue (and like I say the chances of it recurring (from my experience) at not great) so I'll let the professionals take a look at it first!

The defect is in the skin/tissue that covers the mucocele. Becuase the duct that is meant to let the secretions leak through to the mouth is blocked/traumatised the secretions pool underneath and create the blister-like appearance. So the problem isn't in the blister, but in the skin that overlies it. So, cutting this overlying tissue will not 'heal' the problem, it will merely release the built up secretions. When the tissues heals again, there is still a large possibility that the duct will not be able to empty out the secretions.

This is why the most reliable surgical treatment for mucoceles is cryotherapy (freezing) as it kills the glands that are supplying the secretions and allows the tissue to heal.
