Chin implant, did it slide or do I have a more serious issue? (Photos)

The ct scan shows: 22 mm lesion off outer table of left mandible? I can feel it on the left side of my jaw but not the right at all. Since it was 2007 and in another state I have no access to my former doctor's info to get specific details. Revision rhino: Had a septoplasty in which the following was done: Turbinate reduction and nasal valve repair 2018, shaved dorsal hump 2007 How do I discuss revision/wants/best outcome?
