Numbness of the scalp is common for many weeks after surgery. It may take as long as 6 months for sensitivity to return.

My Scalp is Still Numb 4 Weeks After Mohs Surgery is This Normal?


I do a few 100 MOHs repairs every year. Many are in the scalp or forehead. My patients complain of numbness all the time. This is normal. There can be numbness in the scalp due to a sensory niece that runs in he forehead tissue. This nerve can be permanently injured due to the cancer removal or from the flap repair. Fortunately most of the time it is just a "bruised" nerve. It can take from 1-6 months to resolve. If it lasts beyond that some feeling may come back but most likely it will not. The scabs are normal as well.  These are areas either of delayed wound healing or scabs similar to when you skin your knee. They will fall off when the tissue beneath the scabs heal. You seem to progressing in a normal fashion.

Scalp numbness after Mohs


Your numbness is normal. In many instances depending upon the depth that the cancer was, some of the nerves may have been cut, which is causing the numbness. These nerves will regrow and rejoin, but it does take time. As for the scabs, if you can keep the area clean with 1/2 peroxide and water and keeping it free from scabs it would actually be better. I tell patients to keep any removal sites clean and free from scabs and to apply either Polysporin or Vaseline liberally to keep it moist. Scabs=scars, so keeping it moist and clean will actually help it heal faster and better.

Numbness after Mohs surgery


It is perfectly normal to have numbness on the skin after Mohs surgery, even at 1 month post-op. If your surgery was performed on the forehead, the scalp adjacent to the surgical site might feel numb as well. In general, when you cut through the skin during the Mohs procedure, you often cut through the nerves in the skin as well. These nerves regrow, but they regrow extremely slowly. In some patients, it can take up to a year for the nerves to regrow and for this sensation to subside.
