Psammomatoid juvenile ossifying fibroma (PJOF) is a rare benign tumor that usually affects the paranasal sinuses, orbit, and skull. In most cases, extensive incisions are necessary for full access to the tumor site. The aim of this paper is to report a case of extensive PJOF in which an intraoral surgical approach was performed with complete excision of the tumor. A female patient, 18-year old had a deforming volume increase in the region of the left facial middle third with an approximate evolution time of 2 years. She complained of headache, epiphora in the left eye, and total obstruction of the left nostril. Extraoral examination showed facial asymmetry with dystopia, ocular proptosis, and considerable sclera exposition of the left eye. Tomography examination showed a mixed aspect lesion on the left side of the face, well delimited. The intraoral surgical approach was chosen for the excision of the lesion. Under general anesthesia and nasotracheal intubation, total resection was performed, followed by exodontia of the directly involved teeth. In the definitive histopathological examination, the diagnosis was confirmed. The patient is currently with 2 years and 6 months of postoperative follow-up and has good healing of intraoral surgical wounds and stable occlusion. Extraoral examination showed harmonic projection of the facial middle third, but still with excessive exposure of the sclera of the left eye due to the defect in the orbital floor. The surgical treatment of PJOF was possible by intraoral approach, even taking into account the limitations of the access and the complexity of the anatomy of the facial bones involved.
