Welcome to HCM.
You can consult an ophthalmologist trained particularly in Oculoplasty (oculoplastic surgeon)near your area.He / she can help you by assessing the amount of scar and the reconstruction area required to give you the best possible eyebrow and the surrounding structures. They will remove the excess scar and do a transplant if needed.
This procedure is more like a cosmetic plastic surgery
so ,to be very frank, choose the best Oculoplastic surgeon in your region for the best post operative picture of yourself. Take care.
