Brandon L. Miner, DO

Usually I request a minimum of 2 weeks prior to the procedure.   It takes some time for the effects of smoking to reverse.   Once you stop just stay a non-smoker.   There is no need to fix your face just so you can get lung cancer. 

As a fellowship-trained Mohs surgeon I rarely give oral antibiotics for standard cases.   There are however times when it is necessary. It was likely prescribed by the doctor that closed the wound and you should call him/her to see if it is necessary. 

Mohs micrographic surgery is not your only option but it is probably your best.   With a cure rate over 98% and being tissue sparing it will give you the smallest defect and usually scar.  Excision, electrodessication and curretage, are some other options but have lower cure rates.

This can be a normal side effect,  just give it time to normalize.   If after a month or two or it is still flaking call your surgeon. 

If you get too much granulation tissue it can make a full thickness skin graft not match up well.   Were you offered other closure options?  A defect like yours would take a paramedian forehead flap really well.  Consult with your surgeon, only he/she can determine if the granulation is appropriate for grafting.
