Patient: The gum on the left side of the mouth is wide and the CT shows a tumor on the mandible. The doctor suggested three options: 1. Conservative treatment, only removing the tumor and preserving the mandible, but it is easy to recur. 2.Excision of the tumor and the associated mandible, and implantation of titanium plate for support. 3. Remove the tumor and the related jawbone, implant your own ribs, and then grow and heal. I would like to ask the expert: which method should I take better, or is there another better way? If I have surgery, will it be dangerous and will it leave any other after-effects? If I implant a titanium plate or my own ribs, will it recur in the future? Bu Rongfa, Department of Stomatology, Beijing 301 Hospital: The CT diagnosis of enamel-forming cell tumor (i.e. enamel-forming cell tumor) is for reference only, not for confirmation. If it is indeed an enameloblastoma, conservative treatment and titanium plate support are not suitable, and autologous bone reconstruction is still needed. Any surgery will have some risk and may leave some sequelae. The surgical treatment of this disease is probabilistically very unlikely to be life threatening. The elimination of recurrence depends on the removal of the tumor, which is not completely solved by visual and imaging means, but only by bone grafting, which means that the removal is more complete. Of course, the clinical experience of the doctor is also important.
