Thank you for writing in. I can totally understand the agony you are going through with this. I have had the privilege of treating many patients with oral sub mucous fibrosis and of various grades.
In my experience I have seen lesions that are highly advanced with absolutely no effect on mouth opening (some thing that you describe for yourself), and lesions that are still advanced with severe restrictions in mouth opening. Mouth opening is not an important criteria when assessing the severity of the lesion. It's the cellular level changes that have already taken place in the lesion that gives us an information about its potential to turn malignant or not. (I hope a biopsy has been performed from the most relevant part of the lesion). The histopathological results from the biopsy help to determine if there are any malignant changes. If there are no malignant changes and you have completely and absolutely stopped your tobacco consumption, then chances of turning malignant are low. But not zero. The ulcers you are taking about now, are purely due to nutritional deficiency of the oral tissues. Since fibrosis has taken place, blood supply to the oral mucous layer is compromised. And hence the ulcers. Are the ulcers at the same place and do not heal
? Or they occur at different areas at different times? You will have to take care of ulcers symptomatically. If the ulcers are persistent at the same place for a long time and you see it growing. Then it's a cause to worry. A new biopsy of the ulcer
would be required. My advise. If you have truly quit tobacco. Then the healing process has already started. But it will take time. The same time it took to get here will be taken to get back to normalcy. All you can do is to help it heal. Good oral hygiene, vitamin supplements regularly, steroid ointment on the lesion, avoid any kind or harsh stimuli on the area. Hot, spicy etc etc. Once there are considerable signs of healing then adjunctive procedures like intra lesional injections and LASER therapy
can be done. I hope this will help you! Any more questions I'll be only glad to answer!
