Rationale: Ossifying fibroma (OF) is a benign fibro-osseous lesion that can develop in the oral and maxillofacial region. OF is more common in females and has a marked predilection for the mandible, occurring rarely in the maxilla. Lesions grow slowly and are usually asymptomatic until growth produces an obvious swelling, pain, paresthesia, and facial deformity. With low rates of recurrence, treatment is usually curettage or resection. Very large lesions that invade other organs and that cannot be completely removed should be excised conservatively. Patient concerns: We present a case of a 46-year-old female with a very large fibro-osseous lesion arising from the maxilla who was more concerned about the facial appearance and requested conservative treatment for economic reasons. Diagnoses: The pathological results based on conservative excision of the lesion confirmed the diagnosis of OF. Interventions: We chose conservative excision via the Weber-Ferguson approach and followed up every 6 months. Facial deformity correction was performed 2 years postoperatively and right lower eyelid ectropion correction 3 years after the primary excision. Outcomes: The ectropion deformity in the right lower eyelid improved dramatically with a better facial appearance and no obvious swelling. Lessons: Treatment programs for OF should be individualized based on the size, growth rate, invasion, and interference with facial function and esthetics. If lesions grow slowly, we suppose that it is feasible to excise conservatively when reconstruction cannot be performed due to esthetic and functional problems. Also regular postoperative follow-up is necessary to detect recurrence, and to improve facial appearance as required.
