Introduction:
Recurrent ameloblastomas rarely present in the anterior skull base but are, common following inadequate excision.
Patients And Methods:
Three patients are presented with ameloblastoma in the anterior skull base including frontotemporal fossa and pterygomaxillary fossa recurring following multiple enucleations, segmental mandibulectomy, or partial maxillectomy. The recurrences were found 3-4 years following the primary operations. All 3 patients were treated by radical dissection.
Results:
Microscopically one case was a mixed follicular and plexiform, two cases were of a follicular type. All patients healed without serious complications.
Conclusion:
Ameloblastomas in these regions have a greater recurrence potential even when treated by radical dissection.
