Purpose: We reviewed the outcome of treatment of ossifying fibroma involving long bones. Materials and methods: Eight patients who enrolled at our hospital for ossifying fibroma from 1994 to 1999 were selected for this study. Mean age was 7.9 years old. Five were male and three female. Seven involved tibia and one fibula. All cases were diagnosed by biopsy. The initial treatment was conservative and the followings were operative indications; (1) repeated fracture, (2) suddenly growing mass, (3) severe bowing deformity, (4) pseudoarthrosis. We assessed the recurrence by x-ray follow-up. Results: As initial treatment, curettage was performed in 2 patients, observation in 2 subperiosteal resection in one and extraperiosteal resection in 3 patients. Two patients who were observed and 3 patients who received extraperiosteal resection did not suffer recurrence. Two patients who received curettage and one patient who received subperiosteal resection had recurrence. The second treatment was performed in 3 patients. The one case of curettage received extraperiosteal resection. The other was in observation. The case of subperiosteal resection was in observation, too. There were no recurrence and aggravation at follow-up. Conclusion: Ossiying fibroma should to be treated by conservative method. If operation is indicated, extraperiosteal resection could reduce the recurrence.

Ossifying fibroma is one of a group of fibro-osseous lesions which arises typically within the jaw bones and only rarely affects the long bones. Ossifying fibroma of the long bones almost involve exclusively the tibia but may also involve the fibula. Ossifying fibroma of the long bones is distinct from fibrous dysplasia, adamantinoma and nonossifying fibroma with regard to age of the patient, site, radiographic appearance, histological features, and clinical course. We are reporting the cases of seven patients with a tumor-like lesion that named osteofibrous dysplasia. It is most commonly found in the tibia and fibula of a child ten years of age or younger. Of the seven cases reported in this study, only one patient was younger than ten years. In all cases, the lesions were usually located in the tibial diaphysis. The average duration of clinical manifestation was 5.2 years. The clinical symptoms were anterior bowing of the tibia in 2 cases, buldging of the tibia in 2 cases, and mass overlying the tibia in 3 cases. On the roentgenography, it shows multiple radiolucent lesion with intervening sclerotic rim of the tibial diaphysis. In seven patients, 6 cases were confirmed with biopsy. We had done curettage and bone graft in three cases, VFG was done in one case. The other three cases underwent conservative management.

Ossifying fibroma is a relatively slow growing tumor, and likely to have presented for some years before its clinical diognosis. The usually well circumscribed nature of ossifying fibroma in jaws lends itself to relative ease of excision and hence the favorable therapeutic results. On occasion, however, particulary in juvenile patient, if maxilla the tumor assumes an aggressive behavior. In that case, because the tumor grows invasively, resection with a margin of healthy tissue is indicated. The case presented is 34 - year old female. The patient had noticed a gradual swelling of the right side of the face approximately 2 months in duration correlation with a intermittent pain on the right maxillary molar area. Palpation disclosed firm swelling on the right anterior and lateral walls of the maxillary sinus extended to the maxillary tuberosity area. The radiographic examination revealed soft tissue mass with multiple dense round calcifications with destruction of anterior and posterolateral wall of the right maxillary sinus and right alveolar process, and hard palate. The mass totally obliterated maxillary sinus and extended to the pterygopalatine fossa. The histologic diagnosis from the biopsied specimen revealed ossifying fibroma. The tumor mass was resected by subtotal maxillectomy procedure due to a recent rapid infiltrative growth. In 5 months of postoperative follow - up period, the patient has favorable prognosis.
