Ameloblastoma is a benign tumor originating from residues of the dental lamina. Ameloblastoma constitute approximately 1% of all tumors of the jaw, and the occurrence in the mandible is four times higher than that in the maxilla, suggesting that maxillary ameloblastoma is a rare histopathological entity. Although these tumors grow slowly and demonstrate a histologically benign appearance, ameloblastomas are notorious for local invasiveness and a high incidence of local recurrence. We experienced a case of ameloblastoma arising from the left maxilla in a 70-year-old male who complained of left nasal obstruction. The ameloblastoma was completely removed via the endoscopic endonasal approach combined with the Caldwell-Luc approach. At a 29-month follow-up, there was no evidence of recurrence.
