Fibroma ossificante complicado com piocele de seios paranasais: um relato de caso

Abstract

Objectives: To present an unusual case of recurrent ossifying fibroma complicated with osteomyelitis and frontal sinus piocele. Case report: A 50-year-old patient with a previous diagnosis of ossifying fibroma who underwent a surgical procedure for tumor excision in the face 23 years ago. He evolved, about 1 year ago, with the appearance of facial fistulous orifices, with drainage of purulent discharge. The patient underwent paranasal sinuses computed tomography, which showed the presence of cutaneous fistulous pathways in the left frontal and right frontotemporal region, where a small abscessulized collection adjacent to the meningeal plane was notted. The treatment included an external face access, for the drainage of the purulent collection, and prolonged antibiotic therapy. Conclusion: Paranasal sinus ossifying fibroma is a rare disease. Its surgical treatment is very often challenging for the surgeon due to its proximity to noble structures such as the brain and orbit. The involvement of a multidisciplinary team is necessary for proper patient follow-up and management of postoperative complications.
