Psammomatoid juvenile ossifying fibroma (PJOF) is a benign fibro-osseous lesion that mainly affects the paranasal sinuses and periorbital bones. It may cause significant esthetic and functional impairment. Herein, we describe the diagnosis and surgical approach of an extensive PJOF arising in the frontal sinus of a young male. After complete lesion removal and histopathological confirmation, the bone defect was repaired with a customized polymethylmethacrylate implant. PJOF may present aggressive clinical behavior. The excision of extensive PJOF in the orbitofrontal area can result in significant esthetic defects. Polymethacrylate implants restore functionally and esthetically the involved area.
砂粒样幼年性骨化性纤维瘤（PJOF）是一种主要累及鼻窦和眶周骨骼的良性纤维骨性病变。它可能导致明显的美观和功能损害。在此，我们描述一名年轻男性额窦发生的广泛性PJOF的诊断和手术方法。在完全切除病变并经组织病理学证实后，用定制的聚甲基丙烯酸甲酯植入物修复骨缺损。PJOF可能表现出侵袭性临床行为。眼眶额叶区域广泛性PJOF的切除可导致明显的美观缺陷。聚甲基丙烯酸甲酯植入物可在功能和美观上恢复受累区域。
