Tumor eradication and esthetic and functional recovery of upper jaw defects are two of the greatest challenges in the treatment of an extensive maxillary tumor affecting the paranasal sinus. Here, we report a case of successful treatment of an advanced maxillary ameloblastoma extending to the maxillary and ethmoid sinuses and affecting the orbital floor. A 45-year-old man, who presented with a large mass in the left maxilla and a marked swelling of the cheek was referred to our department. He had a medical history of being given a diagnosis of ameloblastoma in the maxilla 13 years ago, but he had not undergone any treatment. Pre-operative radiographic examinations, CT, and MRI revealed a large tumor destroying the maxillary bone and extending into maxillary and ethmoid sinuses. The left nasal cavity was completely obstructed, and the bone of the orbital floor was lifted and deformed. After confirming the tumor as ameloblastoma, excision of the total left maxilla, palate, and orbital floor bone including the tumor extending to the nasal cavity and ethmoid sinus was carried out in joint surgery with an otolaryngologist. The surgical wound of the orbital floor and in the buccal area was covered by a forearm flap and skin graft in order to maintain a direct view of possible tumor recurrence near the skull base. Two years after the operation, there was no recurrence of the tumor. Disturbance of eyeball movement was not detected. Occlusal and speech functions were recovered using a maxillofacial prosthesis made by a prosthodontist. [ABSTRACT FROM AUTHOR] |
