Skin Graft Fell off 2 Weeks After Mohs Surgery

Always a good idea to discuss your situation with the surgeon who treated you. You may find that underneath the scab, there is fully epithelialized and vibrant skin.  Skin grafts can sometimes result in concavities, but these often fill in to some degree. Raffy Karamanoukian, Los Angeles

There is no real way to ascertain what has happened to the skin graft without an examination, and this should be done by your Surgeon sooner rather than later.  Skin grafts heal in phases, because they autogenous material without a blood supply.  Skin grafts (both full and split thickness) take weeks and usually months to look cosmetically acceptable.  For this reason, I very rarely use a skin graft on the nose unless there is a very specific reason to do so.  The initial and long term healing from a local flap (bilobe) yields a better color and texture match in the near and long term than the vast majority of skin grafts.  The biggest concern is the color of the graft, which very rarely matches the tone of nasal skin.

Skin grafts may form a scab on the surface and the deeper part of the graft may be living when the surface comes off. Some grafts lose the dead skin cell layer in sheets without it being a dead graft, but the dead cells that normally flake off every day, and can't be seen, can accumulate under the dressing and peel off after a graft without injury to the graft.  If the whole graft forms a hard scab, it's rare to fall out unless it is traumatically pulled. Cover the wound with a bandaid and call your doctor to be seen and determine how they want you to take care of the wound. Some of these wounds heal fine without additional surgery and sometimes a new graft is done several weeks later after healing allows the wound to fill in as much as possible.
