Fibrous dysplasia is a developmental anomaly of the skeletal system where an anomaly of the bone-forming mesenchyme manifests as defects in osteoblastic differentiation and maturation. It is termed as craniofacial fibrous dysplasia, when it involves, though rarely, adjacent craniofacial bones. Fibrous dysplasia is a developmental tumor like condition in which normal bone is replaced by excessive proliferation of cellu-lar fibrous connective tissue intermixed with irregular bony trabeculae. Written informed consent was obtained from the patient. It is seen in 2 main forms of presentation, monoostotic and the polyostotic form with caf au lait spots and precocious puberty (McCune-Albright syndrome). Involvement of frontal, sphenoid, Monostotic (involve one bone) naso-ethmoid & maxillary bone may lead to nasal obstruction, si- nus obstruction & sinusitis [1]. The mutation results in constitutive activation of Gs and ligand-independent signaling of the Gs-coupled protein receptor that induces the production of cyclic adenosine monophosphate and causes hyperactivity of affected cells. 8.Conclusion: Our case is a monostotic type of fibrous dysplasia involving left maxilla, managed by surgery in which the fibrous dysplas- tic bone was removed by osteotomy.
