Mohs Skin Graft on my Nose Appears to Be Healing with a Significant Indentation/depression - Will It Improve?

A thick split thickness skin-graft contracts better than a full thickness skin graft.  The graft is sutured with a running suture biting the deep skin edge to hold the graft down on the bottom of the wound.  A small puncture is made in the graft to allow drainage.  The graft is now in a deep hole.  A cotton ball the size of the hole is soaked in clindamycin/gentamycin solution and pushed into the hole over a small patch of xeroform gauze to keep the graft down.  The nose is wiped clear of  oils and a steri-strip is glued over the cotton stent.  At first the graft is depressed.  Then, over a few weeks and months it contracts and the hole fills.  For some unknown reason, the wound levels off flat with the surrounding tissue in most cases.  This is not the case in other parts of the face and body.  The nose is special.  We have high success with this technique and every time it happens I am still amazed after 30 years of using this technique.  Best wishes. Knowledge is power.  Luis F. Villar MD FACS

Thank you for your question. It can take months for a fully mature scar to form after surgery, and many times early depressions are improved with time. Typically, it is advised to not fully judge a scar as a permanent result until it has time to evolve into a mature scar (typically after 6-12 mo. of healing). In cases that do result in an unwanted scar or a depression, scar revision surgery may be considered. I hope this helps.

Thanks for your question. 

Skin grafting is one of many options on the reconstructive ladder to fix defects of the nose. The best areas of the nose that heal with skin grafts are the areas with thin and less sebaceous skin. Sometimes, it is ideal to wait a 2-3 weeks for the wound to fill in from bottom up (by granulation) and then place a skin graft. This allows for better contour matches of the skin graft 

 

It is still very early to make a decision about the final result of your skin graft. I tell most of my patients to hold out on making any decisions about revision surgery until 9-12 months have passed. There are times when the tissue can fill in under the skin graft to give it a better contour match. 

 

Best of luck,

Skin grafts are a good option for repairing skin removed due to cancer on the nose. In general, however, they are not the best match possible for color, texture, pore size, and tissue thickness. In almost every case, local flap repair of the nose yields a better result.

Since you have already had the skin graft, continue to follow your doctor's advice and see how the final result is at 9-12 months. If you are still not satisfied, consult with a facial plastic surgeon very experienced with flap repair to consider cutting out the skin graft and replacing it with a flap. 

Full thickness skin grafts are a common method of repairing surgical defects after Mohs surgery. They definitely improve aeshetically with time, with most grafts continuing to mature for 6-24 months. However, at our center, we treat many of these grafts (and other surgical scars) with fractional resurfacing lasers. This greatly improves both the color and texture of the graft scar. Laser treatment can be initiated wihtin a month after the surgical procedure.
