“…Other authors found a balanced distribution between both sexes. 5,6 Only a few cases are reported, [7][8][9][10][11][12][13][14][15] and only some grow aggressive and involve the orbit, the nasal cavity, and even the sinuses. 3,[16][17][18] Nevertheless, some cases of intracranial extension of ameloblastomas are also reported in the literature.…”

Ameloblastomas are a rare tumor entity accounting for only 10% of all odontogenic tumors. They mostly originate from the mandible. Only a few cases are known to grow aggressively and to invade the orbit, nasal cavity, or even the brain. We present the case of a 57-year-old patient who was admitted with a huge tumor involving the nasal cavity, the left maxilla, and the anterior fossa. Histologic diagnosis was made by biopsy. A combined two-stage neurosurgical maxillofacial approach was planned. First the intracranial tumor mass was removed using bifrontal trepanation. A duraplasty was sewn in to cover the brain. In the second procedure, a combined bifrontal and midfacial approach was used by craniofacial plastic surgeons and neurosurgeons. A perisinusoidal tumor mass and retropharyngeal tumor mass was removed up to the skull base. The left orbit was completely exenterated, and a fibular bone-muscle graft was used for palatal, orbital, and facial reconstruction. The facial vein and artery were carefully prepared to feed the bone-muscle graft by end-to-end anastomoses. Ameloblastomas are very rare slow-growing tumors that show a tendency to recur. They are responsible for only 1% of all oral tumors. Their growth can be enormous, and they can extend into sinusoidal cavities, the orbit, and the brain. Complex and extensive palliative surgery can ease the concerns of these patients and prolong their survival.

“…This search found that ameloblastoma affecting the sinonasal cavities is most commonly due to extension of a maxillary tumour. (8,9) There are case reports of extremely rare primary sinonasal ameloblastomas but no previous reports were found of extension of a benign maxillary ameloblastoma into the frontal sinuses, as in this case. (10)…”

“…[1] Although, there are extra-gnathic ameloblastomas that have been shown to arise from misplaced odontogenic rests. [19] When considering the possible histogenesis of sinonasal tract tumors, parallels can be made with peripheral ameloblastomas, which also were believed to originate outside the boundaries of odontogenic epithelium.…”

Ameloblastoma is a benign but locally aggressive odontogenic tumor. Worldwide, maxillary ameloblastoma is rare, but its late detection renders adequate treatment difficult. Majority occur in the mandible with about 5-20% occurring in the maxillary bone. Here we report a case of plexiform ameloblastoma of the left maxilla in a 30-year-old male. The tumor was presented as a radiographically solid mass filling the left maxillary sinus and clinically as a maxillary swelling. The radio-pathological features of this tumor and the possibility of its sinonasal epithelium origin are discussed.
