Introduction: Fibro-osseous lesion is a broad term for a diverse group of jaw and craniofacial disorders that are often painless, but grow progressively, if uncontrolled. They are characterized by the replacement of normal bone by fibrous connective tissue matrix displaying varying degrees of mineralization in the form of woven bone or cementum-like structures.
Methods: Retrospective survey of the records of all patients seen between 2000 and 2013 at the department of Oral and Maxillofacial Surgery Clinic, Ahmadu Bello University Teaching Hospital, Zaria, Nigeria was undertaken.
Results: A total of 104 patients were seen over the period of study. Of these, males comprised 40 and females comprised 64 giving a male to female ratio of 1:1.6. The age ranged from 4 years to 66 years and mean was 25.8 (13.21) years. There was no gender difference in terms of age (t = 1.78; p = 0.078). Fibrous dysplasia was the most common lesion and accounted for 60 (57.7%) of the cases and this was followed by ossifying fibroma (n = 39; 37.5%).
Conclusion: Due to late presentation, the size of the lesion, the outcome is usually not good aesthetically, especially for maxillary lesions.
