An Uncommon Presentation of Ossifying Fibroma in the Maxilla

Abstract

Ossifying fibromas are rare, benign, nonaggressive fibro-osseous lesions that manifest in the craniofacial region. Ossifying fibromas are benign tumors of bone, commonly involving the posterior dentate mandible in middle-aged individuals with a female predilection. Clinical manifestations are an asymptomatic expansion of the dentate mandible, with infrequent maxillary lesions. Benign fibro-osseous lesions of the maxilla exhibit similar histopathological findings. Cone-beam computed tomography scan plays an important role in diagnosing and understanding the invasiveness of this lesion. This case report describes an uncommon presentation of ossifying fibroma in the posterior maxilla in an adult male patient. Treatment consisted of surgical excision, and wound healing was uneventful during the one-year postoperative follow-up period.

Ossifying Fibroma in the Maxilla and Mandible: A Case Report With a Brief Literature Review

“…The mandibular canal near the tumor is usually inferiorly displaced. OPG shows a well-defined unilocular mixed lesion with a ground-glass appearance internally surrounded by a thin radiopaque margin; root resorption may be present [19,20]. In our case, the OPG showed large well-encapsulated, well-demarcated, mixed radiolucent and radiopaque lesions with a peripheral radiolucent area in the maxilla and mandible.…”

“…Radical surgery is indicated to reduce the tendency of recurrence and the possibility of malignant transformation. A fibrous capsule allows for easy surgical excision and resection, as in our case with the massive tumors -a study of 25 OF patients by Liu et al [16,20]. The following methods were used: 36% (n=09) in the mandible had enucleation and curettage; 32% (n=03) had segmental mandibular resection and reconstruction with reconstruction plate; with 20% (n=05) reconstructed with microvascular fibula graft.…”

Management of ossifying fibroma of the bone of the maxilla: a case report and review of the literature

“…Our case report showed an uncommon presentation in the anterior part of the maxilla of a 26 year old male patient. Due to the great fraction of cancellous bone and the sinus existing in the maxilla, OFs of the maxilla can enlarge and grow to huge sizes [ 4 ]. In our case, the lesion was occupying most of the anterior maxilla left side, and the patient presented with considerable clinical symptoms that included moderately facial distortion.…”

“…An extension to the nasal septum, orbital floor, and infraorbital foramen can be seen in larger lesions [ 3 ]. Rarely, OF is associated with the destruction of extraosseous soft tissue components [ 4 ]. The tumor rarely recurs after adequate surgical treatment.…”

Cemento-Ossifying Fibroma of the Mandible: A Case Report

“…There are two types of COF: conventional COF and juvenile COF. Conventional COF presents as slow-growing, while juvenile COF grows quickly [ 3 ]. It is thought to originate from multipotent mesenchymal cells in the periodontal ligament area, which can create fibrous tissue, cementum, and lamellar bone [ 4 , 5 ].…”
