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

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.
