Patient: In April 2010, I found a small blister on the lower lip of my mouth, and at first I didn’t pay attention to it and thought it was an ordinary bubble. I did a surgery, half a month after the surgery and found another bubble in the surgical site. Can I do it again only half a month after the surgery, or wait for the bubble to grow a little to do, how to treat it to eradicate it Doctor: your situation is currently common in the country, but in our Nanjing Oral Hospital maxillofacial surgery has almost never happen. First of all, there are many glandular vesicles distributed under the mucosa of our lower lip, which secrete mucus to the oral cavity through their respective tubules to keep our oral mucosa moist, and they cluster in clusters. When the lower lip is bitten, the scar-like tissue formed during the repair process will block the secretion of the tubules, resulting in the retention of mucus to form mucus gland cysts. We remove the cyst and the glandular vesicles below during surgery, but the glandular vesicles at the edge of the incision are also vulnerable to injury at the same time, including stitches, so often translucent blisters come out of the surgical area about half a month after surgery, which is called recurrence of the surgical area. In our hospital, we take the glandular vesicles at the edge of the incision and remove them completely, because as I mentioned earlier, the vesicles are clustered together, not singly, and although it takes a few days to swell after surgery, we do not see a recurrence in the area soon after surgery. In addition, the good area can often see the misaligned teeth, easy to bite again to the glandular vesicles outside the surgical area, in order to avoid the reappearance (not the short-term recurrence of the surgical area), we will explain the patient attention. Large dental hospitals do more than rarely pay careful attention to major surgery, including your Sichuan Huaxi oral cavity, as for small hospitals textbooks do not speak of, so cause you a lifetime of surgical doubts is not enough to blame, you do not go to blame for anything. Finally, it is recommended that you can now operate again, but according to our method.
