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 ...
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.
Turricephaly. Turricephaly is a type of cephalic disorder where the head appears tall with a small length and width. [3] [4] It is due to premature closure of the coronal suture plus any other suture, like the lambdoid, [5] or it may be used to describe the premature fusion of all sutures. [2] It should be differentiated from Crouzon syndrome.
Acrocephalosyndactyly. Acrocephalosyndactyly is a group of congenital conditions characterized by irregular features of the face and skull ( craniosynostosis) and hands and feet ( syndactyly ). [1] Craniosynostosis occurs when the cranial sutures, the fibrous tissue connecting the skull bones, fuse the cranial bones early in development.
Octave Crouzon. Louis Édouard Octave Crouzon (1874–1938) was a French neurologist born in Paris. He received his doctorate from the University of Paris, where he studied under Paul Georges Dieulafoy (1839–1911), Joseph Babinski (1857–1932) and Pierre Marie (1853–1940). During his medical career, he was associated with the Hôtel-Dieu ...
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. Some people could develop it due to poor dental extractions. [1]
Choanal atresia is a congenital disorder where the back of the nasal passage ( choana) is blocked, usually by abnormal bony or soft tissue (membranous) due to failed hole development of the nasal fossae during prenatal development. It causes persistent rhinorrhea, and with bilateral choanal atresia and obstructed airway that can cause cyanosis ...
Dolichocephaly (derived from the Ancient Greek δολιχός 'long' and κεφαλή 'head') is a term used to describe a head that is longer than average relative to its width. In humans, scaphocephaly is a form of dolichocephaly. Dolichocephalic dogs (such as the Lurcher or German Shepherd) have elongated noses. This makes them vulnerable to ...
