Juvenile ossifying fibroma of the jaw: a retrospective study of 15 cases.

The management of patients with juvenile ossifying fibroma (JOF) remains controversial. To explore the correlations between different treatments and the patient prognosis, 15 cases of JOF of the jaw were reviewed. Five patients were male and 10 were female. Patient age at the time of disease onset ranged from 7 to 18 years (mean 10.9 years). Nine tumours were located in mandible and six in the maxilla. These cases typically manifested clinically as painless swelling of the jaw (9/15, 60%); 40% (6/15) of the cases were associated with pain, diplopia, stuffy nose, and/or rapid growth. Images of JOF can show a radiolucent, mixed, or ground glass-like appearance. Pathological examinations revealed 10 cases of juvenile trabecular ossifying fibroma (JTOF) and five cases of juvenile psammomatoid ossifying fibroma (JPOF). In terms of the treatment plan, six patients initially received radical surgery; nine patients underwent conservative treatment, among whom six (6/9, 66.7%) had one or more recurrence. At the end of the follow-up period, 12 patients had no evidence of tumour recurrence and three cases were alive with a tumour. In summary, surgeons should develop the surgical plan according to the extent of the lesion, relapse status, growth rate, and family choice, and these patients should be followed up closely.
