What Happens to Mohs Surgery Scar when Healed by Itself?

Depending on the size and location of the surgical defect, second intention healing can give a better cosmetic result than having reconstructive surgery.  However, it is not appropriate in all cases.  

If matching the adjacent skin is a concern, a flap or complex closure depending on the size and location of the nasal defect will give a better match to the adjacent nasal skin. The level of care required will be greater with the flap, but the aesthetic results after it has completely healed will be worth it.  

If you decide to let the wound heal on it's own and you are not satisfied with the final outcome, a revision procedure can be planned with your reconstructive surgeon.

 

It's amazing how well the skin can heal on its own (called healing by secondary intent).  It may possibly be depressed after healing or heal over too much (become a raised bump).  If it heals too much, that can easily be repaired.  A depression is more difficult to repair but can be done possibly be dermal implant or filler.  If you're not happy with how it looks you can always opt to have more surgery later.
