Abstract

Skeletal Class III malocclusions are frequently associated with craniosynostosis syndromes, resulting in distinctive facial and dental anomalies. Among these, Crouzon syndrome is characterised by mutations in the FGFR2 gene, leading to premature fusion of the cranial vault, cranial base, orbital and maxillary sutures. The phenotypic expression of this congenital condition varies according to the timing and pattern of sutural fusion. This report details the clinical features and management of a 16-year-old male patient presenting with moderate skeletal Class III malocclusion as a manifestation of Crouzon syndrome. The present case fell within the spectrum of conventional non-surgical management. Adjunctive chin cup therapy initiated after rapid maxillary expansion aided in controlling residual mandibular growth, contributing to a favourable outcome in a hypodivergent pattern. Functional and aesthetic outcomes were markedly enhanced, and the results remained stable at the one-year follow-up assessment. Excellent compliance over 36 months contributed to treatment success and stability.
