Crouzon syndrome is an autosomal dominant genetic disorder known as a branchial arch syndrome. Specifically, this syndrome affects the first branchial (or pharyngeal) arch, which is the precursor of the maxilla and mandible. Because the branchial arches are important developmental features in a growing embryo, disturbances in their development ...
Literature has suggested that persons with Crouzon syndrome typically have conductive hearing loss caused by middle ear effusion (or fluid in the middle ear) and perforation to ossicular fixation ( ossicles ), intratympanic bony masses ( tympanic membrane ), ossicular anomalies and closure of the oval window.
Crouzonodermoskeletal syndrome is a disorder characterized by the premature joining of certain bones of the skull (craniosynostosis) during development and a skin condition called acanthosis nigricans. Some of the signs and symptoms of Crouzonodermoskeletal syndrome are similar to those seen with Crouzon syndrome.
Currently, Noack syndrome (ACPS type I) is now classified as Pfeiffer syndrome (ACS type V); Goodman syndrome (ACPS type IV) is classified as a variation of Carpenter syndrome (ACPS type II); and different researchers have combined Apert (ASC type I), Crouzon (ASC type II), and Pfeiffer (ASC type V) syndrome into Apert-Crouzon and Crouzon ...
Apert syndrome is a form of acrocephalosyndactyly, a congenital disorder characterized by malformations of the skull, face, hands and feet. It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch , the precursor of the maxilla and mandible .

Maxillofacial surgery. Maxillary hypoplasia, or maxillary deficiency, is an underdevelopment of the bones of the upper jaw. It is associated with Crouzon syndrome, Angelman syndrome, as well as Fetal alcohol syndrome. It can also be associated with Cleft lip and cleft palate.
Crouzon was the first to describe a condition he called "craniofacial dysostosis", defined as a genetic branchial arch disorder that results in abnormal facial features. Today this condition is known as Crouzon's syndrome .
View/Edit Mouse. Fibroblast growth factor receptor 2 ( FGFR2) also known as CD332 ( cluster of differentiation 332) is a protein that in humans is encoded by the FGFR2 gene residing on chromosome 10. [5] [6] FGFR2 is a receptor for fibroblast growth factor . The protein encoded by this gene is a member of the fibroblast growth factor receptor ...
There are some genetic syndromes, in which hearing loss is one of the known characteristics. Some examples are Down syndrome (aneuploidy), Usher syndrome (autosomal recessive), Treacher Collins syndrome (autosomal dominant), Crouzon syndrome (autosomal dominant), and Alport syndrome (X-linked).
