The treatment and prognosis of benign fibro-osseous lesions of jaw

다국어 초록 (Multilingual Abstract)

The benign fibro-osseous lesions (BFO) of the jaw are well known for their good prognosis and their clinical entities defferentiated with fibrous dysplasia.
Our objectives of this study are to review these lesions, and confirm their clinical-radiologic-histologic characteristics.
We have analyzed the eighty patients who visited in the Dept. of oral and maxillofacial surgery, Seoul National University Hospital, from January 1, 1984 to March 31, 1994 as being diagnosed with benign fibro-osseous lesions. We have compared their clinical features, radiologic findings and treatment methods, and have investigated their individual prognosis.
The results were as follows ;
1. The benign fibro-osseous lesions occured frequently in the 3rd to 4th decades, and the ratio of male to female was 1 : 2.2.
2. The subjective duration of lesions more than one year was 53.75%. The chief complaint was swelling in 80% and pain was uncommon.
3. In the case of an ossifying fibroma, the peripheral type was frequent, but in the case of a cementifying fibroma and cemento-ossifying fibroma, the more frequent type was the central.
4. Conservative treatement was used in 82.50% and the recurred cases were 5%.
In conclusion, the prognosis of BFO was god after complete enucleation. Recurrence was unusual and malignant change was none. BFO is a more mild lesion than fibrous dysplasia and we suspected that the mesenchymal stem cell is a major contrubuting factor in the development of the lesion.
