Listed below are some general risks associated with skin surgery. Your dermatologist will discuss these risks and any additional potential problems associated with your case.
If you experience numbness, sensation will usually, but not always, return. In most circumstances, nerve function will return over a prolonged period of time, up to 24 months. In some cases, numbness may be permanent.
If a motor nerve is involved, you may be unable to move the muscle. For example, you may be unable to wrinkle your forehead. Prior to your surgery, your dermatologist will discuss any major nerves that may be near the skin cancer.

Every technique that results in the destruction of skin cancer can result in the formation of a scar. Scarring is part of the process of healing. Scarring evolves and matures over 6 months to 2 years, depending on the location of the treated area. Some locations scar better than others. The face heals better than the back, chest, or shoulder. In addition, different biopsies, surgical techniques, and treatment options will result in different shapes of scarring.
Sometimes scarring can be improved. Raised scars can be surgically leveled with dermabrasion or the use of a laser, or they can be flattened with corticosteroid injections.
Any surgery will result in some scar formation; however, your dermatologist will place the cut so that the resulting scar will be within the skin line. During the healing and maturation process of the scar, it is important to protect the area from the sun since sun exposure can result in a brownish discoloration of the scar, making it difficult to treat and fade over several years.
Rarely, soft tissue augmentation in the form of injectable collagen is used to improve depressed scars. A laser is also sometimes used to treat broken blood vessels and redness associated with the scar. Use of multiple over-the-counter products, including silicone patches and gels, as well as daily massage can help improve and speed the maturation process.
Your dermatologist will discuss with you the most appropriate products to treat your scar.
