Mohs Surgery Scar on Nose

Before anyone discusses revision of a scar for cosmetic reasons, please note that your photograph preoperatively shows a whitish flat spot.  This type of basal cell skin cancer is usually an infiltrative type of pattern of growth so it doesn't look clinically typical and may spread for a wide area. It grows with little strands in different directions underneath the epidermis. In your current photograph, there again, is a white area which may represent scar from some tissue scabbing that you might have had in the acute postoperative period years ago, or this might indicate that there is persistent disease of that basal cell carcinoma.  This must be thoroughly explored prior to embarking an revision of the scar.  You may need a biopsy, taken appropriately of the right depth to show a pathologist the dermis so as not to get a false negative result if there is not enough tissue to see it.  This will leave another scar present on the nose!

If a biopsy is done and the skin cancer specialist is confident that there is no tumor present clincially and histologically (under the microscope) then a precise scar excision and resuturing may improve the slight groove and mismatch of skin that often occurs in the thick oil-gland rich skin of the nose.  This may result however, in a worse scar.  Dermabrasion or Fraxel Restore laser done in a series of multiple treatments may improve the texture of the scar significantly.

As your skin came together from both sides of the nose it made the skin quite tight. Despite some stretching of the skin that develops over time after these closures, the pressure caused the cartilage of the lower nose to bow. You may benefit from a rhinoplasty to build up this profile and support the nasal tip better, especially if a scar revision is done by excision and reclosure that would make this even tighter. 

Thank you for the question. You have a depressed wide scar on the nasal bridge. Dermabrasion may help level off the step off, but it will not improve the widen scar. If simpler techniques fail to give you the improvement you wish, I would suggest a scar irregularisation technique, 1- to the make the scar thin and 2- to break up the long linear scar on the nose. The exact technique used would depend upon how much skin laxity you have on the nose. I hope this helps. If you wish for more information I would direct you to this book chapter - Chapter 34 Scar revision, Book Title - Facial surgery : plastic and reconstructive - Authors - Faris, Vuyk. I hope this helps.

After the wound has healed in the first few weeks, the best methods to treat scars are massage and silicone ointments (such as Biocorneum or ScarAway).  the scar is not stable until about 8-12 months after surgery.  I recommend these treatments for at least this long. If there is a contour deformity after a year, a surgical "touch-up" can be performed.  Lasers can help as well.
