Abstract

Ameloblastoma is a rare odontogenic tumor with characteristics of epithelial tissue that produces enamel for the developing tooth. This lesion is generally considered benign, but has malignant forms that invade locally and metastasize. We present a 60-year-old man with maxillary ameloblastoma that after multiple recurrences developed intracranial extension with dural involvement of the middle cranial fossa and was treated by endoscopic transnasal resection followed by radiation therapy. Our technique and intraoperative findings are described with a review of the literature on intracranial ameloblastoma. This patient represents a unique account of endoscopic transnasal resection being utilized in the treatment of intracranial extension of ameloblastoma and demonstrates potential for application in similar cases.
