Treatment of the ameloblastoma: a controversy.
Treatment of the ameloblastoma should be re-evaluated based on microscopic behavior. We suggest that conservative therapy is the initial treatment of choice. Although medullary bone is invaded by tumor cells, compact bone only is eroded. Therefore, treatment should be directed at removal of involved medullary bone, leaving as much medial and lateral cortical plates and inferior mandibular border as possible. Four patients with ameloblastoma treated conservatively are presented. Evaluation from 21 months to seven years after initial therapy revealed marked bone regeneration. Three of the four had smaller lesions remaining, requiring less radical surgery than would normally have been performed initially. No tumor was evident on rebiopsy of the fourth patient. Conservative treatment and proper follow-up were acceptable methods of initial treatment in our cases.
