Fibro-osseous lesions (FOL) are a poorly defined group of lesions affecting the jaws and
craniofacial bones. All are characterized by the replacement of bone by cellular fibrous tissue
containing foci of mineralization that vary in amount and appearance. Diagnosis of these lesions
based on histological appearance alone has considerable limitations. So proper categorization
requires good correlation of the history, clinical findings, radiographic characteristics, operative
findings, and histological appearance.
Here we report a 20-year-old woman with large fibro-osseous lesion measuring 7x5x4 cm which
was located in the premolar and molar region of mandibula who treated via submandibular
approach as the inferior alveolar nerve was protected carefully. Mandibular resection was
performed under general anesthesia and reconstruction plate was placed. Postoperative healing
was uneventful. Patient was followed up monthly and lower lip paresthesia still remains for 6
As aggressive behavior and recurrence is a frequent finding in few patients with FOL, clinicians
must be aware of radiologic and clinical findings to detect the lesions as early as possible.
Despite small lesions can be treated with conservative surgical procedures, in larger lesions,
reconstruction after resection may be necessary as in our case.
