Objective:
To study the clinic presentation, radiology, pathology of recurrent ameloblastoma (RAB).
Methods:
All RAB cases accepted treatment in School of Stomatology of Nanjing University during 1996.1-2008.3 were retrospected. The clinic presentation, the radiological classification and pathological classification were summarized and analyzed.
Results:
There were 23 RAB patients during 1996.1-2008.3. 3 patients recurred twice, 20 patients recurred once, and 26 cases were found together. 19 patients were performed conservative surgery while 4 patients were performed radical surgery in the primary treatment; 4 patients were performed conservative surgery and 19 patients were performed radical surgery in the recurrence. The radiological classification included 12 cases multicystic, 6 cases unicystic, and 8 cases extraosseous. The pathological classification included 21 cases follicular ameloblastoma, and 5 cases plexiform ameloblastoma. The multicystic after conservative surgery (11 cases) and extraosseous ameloblastoma after radical treatment (8 cases) were more than others according the radiological classification and treatment.
Conclusion:
Conservative surgery has apparent higher recurrences rate than radical surgery. The follicular ameloblastoma has more aggressive biological behave and is more liable to recurred.
