How do I remove this bump on my lip?

It is a mucocele or a scar. Either way, a removal of the lesion is appropriate at 2 years since injury. I do lip lips and lip reductions all the time and this is just another type of targeted lip reduction. It is performed under local anesthesia in the office.Gary Linkov, MD

this likely needs to be fully excised and sutured closed. that may leave a scar that can then be lasered however, you can try co2 laser excision or needle excision and if that doesnt work alway go to doing the surgery.  Please see an expert, we are in NY every few months and can accomidate. In mean time use lip plumper and enzymatic exfoliation to minimize its look (see link).  Best, Dr. Emer.

I think you probably have developed a bite fibroma, which is a type of scar tissue.  It just needs to be excised completely, which will require a few stitches.

Dear Mj131313,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would get the best results from excision. It can be done under local anesthesia. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

I think the bump on your lower lip just needs to be excised, so that it is removed completely.  This would be a relatively minor procedure that could be done in the office.  

Thanks for sharing your case with us. There are this treatments called enzymes who can try to dissolve that. It takes sessions and time to achieve the results and make it dissapear. Go with an expert and set the best plan suited for you. Best luck.

Hi there,If the lesion has been shaved twice then that tells you that there is a deeper component.This needs to completely excised ; but will leave you with a scar likely that can be helped with laser afterwards.See a good plastic surgeon.Best of luck...
