Osteoradionecrosis (ORN) is not always a disfiguring surgery. This type of intricate surgery is very individualized. Every patient is different and ORN is a prime example of this. Ive known several people who have had this done and its barely noticeable. Ive also known others who havent turned out as well and sadly yet others who have passed away due to not being treated. The longer the delay, the more difficult it is to treat the ORN.

If the surgery would result in disfigurement, reconstruction surgeries can be always be done later. If this would happen in your husbands situation, dont be surprised to hear he must wait a minimum of one year before he can have corrective surgery. So if your husband isnt satisfied with how he looks afterwards, it can get corrected down the road. After this type of surgery, swelling takes weeks to subside, healing even longer. He may need hyperbaric oxygen treatments (HBO) prior to and after surgery. Dont be surprised if he isnt on antibiotics afterwards for a short time too.

Hopefully this helps, heres more info too...
