I Had Mohs Surgery Above my Right Eyebrow (On the Forehead) - Itching/Healing?

The itching from normal wound healing is usually not so bothersome as the itching that can be caused by an allergic reaction to the polysporin.  Ask your doctor if they agree that a dilute distilled white vinegar solution can be used as a compress to keep the wound clean and minimize itching. Furthermore, stop the polysporin and ask the doctor for a prescription antibiotic ointment that rarely causes itching. Make sure you are seen regularly through the healing process by your doctor.

I agree that neosporin can result in allergy and inflammation of the forehead tissues. Vaseline, aquaphor can also be used and will minimize some of the irritation. Most importantly, these defects heal quite well on their own (secondary intention healing) but require patience. It sounds like you're caring for this wound very well. Keep up the good work!Stephen Weber MD, FACS

Itching is a sign of wound healing due to release of chemicals in the skin called histamines.  Antihistamines (ie: Benadryl, Allegra, Zyrtec, etc.) and topical steroids might help you with the itching.  You should talk to your doctor to get a prescription for the topical steroids.  Intense redness or rash accompanied by itching could be due to an allergic reaction to either the antibiotic ointment polysporin or material in the bandage or dressing.  As mentioned in the other responses, you should try switching to Aquaphor or vaseline to see if that helps.  Also, stop using adhesive to see if that helps.  

Second intention healing (allowing the wound to heal on its own) may be a very good option in your case.  The wound typically gets smaller with time.  If the final scar  is not satisfactory, often a revision may be considered if you're up for it and the scar is bothersome enough - (you need to wait up to a year to decide on what it will look like). Results can actually be quite excellent in some/many cases depending on the defect and your healing.

Severe itching is unusual and raises the question of allergy (e.g. to polysporing) - this would be a reason to revisit your doctor.

It sounds like you are going through a lot. If handled well, a wound "healing by secondary intention" or granulation can look decent in this area, but two months is a long time for you to have to deal with it. I agree with the above answers, that polysporin is a likely culprit for causing itching. Itching and irritation caused by an allergic reaction can also slow down wound healing, so do not feel like you should suffer through this just for the "right" treatment. Vaseline or generic petroleum jelly is a very good would healing ointment that also prevents the growth of bacteria on the wound. You should check with your surgeon and see if it is all right to switch.

Secondarily, the forehead has a lot of nerves of sensation that run through it, so as your skin is realizing it was traumatized, the small nerve fibers that were cut in the surgery are waking up and starting to figure out how to regenerate. This can cause itching, numbness, and funny sensations.

Keep in touch with your surgeon if you are uncomfortable. It is his job to make sure nothing is wrong.
