Abstract
BACKGROUND: Ameloblastoma represents the most common epithelial odontogenic tumor. Because of the proximity of the maxillary tumors to the orbit and skull base, it should be managed as radically as possible. Maxillectomy mainly via the transfacial or transoral approach represents the most common type of surgical procedure. Drawback of these approaches is limited control of the superiomedial extent of the tumour in the paranasal area. We report the use of a combined endoscopic endonasal and transoral approach to manage maxillary plexiform ameloblastoma in a 48 year old male patient. A combined endoscopic endonasal and transoral approach enabled the radical removal of tumour with a 1.5cm margin of radiographically intact bone with good control from both intrasinusal and intraoral aspects. Adequate visualization of the extent of the lesion (e.g. orbit, infratemporal fossa, anterior cranial base) had been achieved. Non-complicated healing was achieved. This technique of partial maxillectomy led to very good aesthetic and functional results. No recurrence had been noted during review appointments.
CONCLUSION: The combination of endoscopic endonasal and transoral approach for a partial maxillectomy allows sufficient reduction of the defect thus eliminating the necessity for reconstruction and reducing the morbidity associated with it.
