Background: McCune-Albright Syndrome (MAS) is a genetic disorder with a triad of endocrine diseases, caféau-lait macules and fibrous dysplasias. Craniofacial fibrous dysplasia is a term that is used to describe the fibrous dysplasia which were localized at the craniofacial skeleton and it is common in MAS patients.

Objective: The objective of this review is to determine the involvement frequency of cranial and facial bones in the patients with MAS and CFD.

Methods: Articles in PubMed was searched with the following details “(mccune[Title/Abstract] OR albright[Title/Abstract]) OR ("craniofacial fibrous dysplasia"[MeSH Terms] OR ("craniofacial"[All Fields] AND "fibrous"[All Fields] AND "dysplasia"[All Fields]) OR "craniofacial fibrous dysplasia"[All Fields])”. The articles in which the authors did not stated the involved bones or did not add any radiographic images were excluded from the study.

Results: 26 cases in 25 articles which met the inclusion criteria was found. Among the 26 cases and our case, sphenoid and frontal bones were involved in 17 cases, parietal and occipital bones were involved in 15 cases, mandible and ethmoid bone was involved in 14 cases, maxilla-zygoma-temporal and palate was involved in 13, 11, 6 and 3 cases, respectively. Palate was involved in cases where maxilla was also involved. Our case was the only case which was evaluated with CBCT.

Conclusion: Routine follow ups are important since new CFDs can occur in different cranial or facial bones. 2D imaging techniques may not be able to demonstrate early CFDs; thus, an advanced imaging technique should be used after MAS diagnosis.

Keywords: Craniofacial fibrous dysplasia, polyostotic fibrous dysplasia, cafe-au-Lait spots, cone-beam computed tomography, panoramic radiography.
