Oral PathologyCrouzon syndrome is characterized by early synostosis of cranial sutures (craniosynostosis), maxillary hypoplasia, and a prominent nose resembling a "parrot beak." This syndrome is caused by mutations in FGFR2 gene leading to premature fusion of skull sutures, resulting in characteristic facial features including proptosis, hypertelorism, and midface retrusion. Treacher Collins affects mandibulofacial development, Pierre-Robin involves micrognathia, and Marie-Sainton is cleidocranial dysplasia.
