Will septal mucosa regrow? I do not have a hole in my septum yet, and am hoping the mucosa will regrow and I can avoid surgery.

Hello, I have been using cocaine daily for about the past 9 months. I have recently stopped completely. As of now I do not have a hole in my septum, however when looking in to my nasal cavity I do see that there is a circular white spot on my septum. I am assuming this is damaged or dead nasal mucosa tissue. My questions is if this will heal on it's own? If so, what is the best way to encourage the healing so that the cartilage in the septum does not erode? Thanks!
