I have a lump of hard scar tissue on the inside of my lip from an injury 15 years ago. It causes me to have the appearance of a slight fat lip. I am not as concerned about the appearance of it, but it is bothersome having this in my lip. One plastic surgeon who saw an image of it wants to inject a steroid into it but I am skeptical this will work. What would be the best course of action?
Excise it!
While a steroid injection is rather unlikely to resolve the scar, it is also unlikely to have any untoward consequences. If you were hesitant to have it excised, you could try the steroid and when it failed, you might be less reluctant to move on to excision. In sum, scars like this are best treated by excision.
Surgial removal is best. It is a common out-patient procedure that is performed under local anesthesia and with use of absorbable sutures. Practically Zero down time and low cost drcaloca@drcaloca.com
Since the injury was 15 years ago, a steroid most likely will not work. This is most likely scar tissue. An excision can be performed in the office to help this. The scar can be hidden nicely inside the lip. It is my practice that any specimen that is removed should be sent to the lab for pathological examination.
Best wishes
My advice to you would be to just leave it alone. It can only be seen by you or if just looking for it. If you must have something done then surgical removal would possibly help but could end up just as bad or even worse and you would have to accept that risk.
