Yes, this is possible. Typically we recommend waiting at least 12 months for the scar to mature on its own prior to considering a revision. If a revision is necessary, either the entire scar can be removed (along with the standing cones of skin) or two small excision of the cones can be performed. I hope this information is helpful.

It can take 6-12 months for a scar to heal, so I would wait a longer amount of time to see the results of the surgery on your cheek. Normally, any dog ears at the end of a scar do flatten out more over time. If they do not, it is fairly simple to make a small incision over each to improve them.
