Procedure to Fix Uneven Top Lip Due to Accident?

Lip scar revision or lip fillers can help realign and improve the upper and lower lips after an accident or laceration. Our office specializes in lip repair. Raffy Karamanoukian MD FACSLos Angeles

If your lip is "notched upward" after trauma, this may be correctable with an injectable filler treatment. By putting volume in the notched area, you might gain improvement in your appearance. Feel free to post / email me a photo, and I'll be happy to give you my thoughts.
I hope this helps, and best regards.

The face and lips are a very unforgiving area when dealing with injuries and sutures. It sounds like your lip shape has changed based on the way it was injured and healed. Without seeing you (or seeing photos) I can't tell what treatment would be best for you. If you have extensive scar tissue, it may be an injection of a steroid. If it is a scar of some sort, you could benefit from a laser. If it's unevenness, a filler might be a good option for creating symmetry. I recommend either posting photos or seeing a doctor in your area. Best of luck! 

Sounds like the wound contraction may have lifted your upper lip. There is a scar revision technique called the Z-plasty that can lengthen the tissue of the upper lip to lower that particular area that has contracted. I would consult with a head & neck or facial plastic surgeon to discuss your options.
Good luck.
