Hi, I was diagnosed by Ameloblastoma (calcifying odontogenic cyst) in my mandible at 2005. The surgeon removed the cyst in a tough operation with general anesthesia, but unfortunately recurrence has been identified in 2014! The second surgery was done (this time a local anesthesia) and my doctor told me you need to follow up your situation carefully. So, I went for panoramic dental X-ray (OPG) once in a year until 2016. Then it was every two years until now and happily it was not appeared again by now. However, since the first surgery, I had no problem in my face, neither any pain, etc. The surgeon told me if we see it comes again we do the resection operation but don't worry. The possibility is very low based on my age (I am 38 now).
