Monofocal maxillary fibrous dysplasia with orbital, nasal and oral obstruction.

Abstract

Fibrous dysplasia is a condition characterised by excessive proliferation of bone-forming mesenchymal cells. Although a variety of causative factors are described, the exact aetiology is yet to be fully known. The maxilla is the most commonly affected facial bone, with facial asymmetry being the usual complaint. Surgery is the treatment of choice with two available options, namely, conservative bone shaving and radical excision and reconstruction. We describe the case of a 25-year-old male who presented with a giant monofocal fibrous dysplasia of the left maxilla with facial asymmetry, including obstruction of the left orbit, nasal and left half of the oral cavities and was treated with conservative surgery.
