Embryology of the Branchial Arches

2019
The pharyngeal or branchial arches are six curved cylindrical mesodermal thickenings on each side of the primitive pharynx. Each arch forms a swelling on the outer surface of the embryo and a swelling on the wall of the primitive pharynx internally. They are produced by the proliferation of the mesoderm of the lateral wall of the pharynx forming six ...

The branchial arch syndromes.

Transactions of the ophthalmological societies of the United Kingdom, 1984
Malformation of those structures derived from the first and second branchial arches are frequently accompanied by ocular and adnexal abnormalities. Ophthalmologists should recognize the various syndromes involved so as to ensure appropriate multi-system evaluation of their patients, and the avoidance of potentially life threatening complications.

Branchial cleft and arch anomalies in children

Seminars in Pediatric Surgery, 2006
Branchial anomalies are important lesions to consider in the differential diagnosis of head and neck masses in children. These anomalies are composed of a heterogeneous group of congenital malformations that arise from incomplete obliteration of pharyngeal clefts and pouches during embryogenesis.

[Persistence of the third branchial arch].

Acta otorrinolaringologica espanola, 2006
The third branquial arch anomalies represent less than 1% of this deformites. The clinical manifestation can be varied althouth the formation of cysts is the commonest one and may appear at any time in life. We report the clinical case of a 7 year old boy with an neck mass. This mass was diagnosed as a branquial cyst.

COT DEATH AND THE THIRD BRANCHIAL ARCH

The Lancet, 1976
Congenital anomalies of the parathyroids in cases of cot death have been reported by several workers. Carotid-body hypoplasia also has been noted in typical cases of cot death. Neurally conditioned airway occlusion at the oropharyngeal level has been postulated as a precipitating factor of cot death.

Biological Basis of Branchial Arch Diseases

2021
Craniofacial malformations account for approximately one-third of all congenital birth defects. This high percentage of malformation occurrence is based on the complexity of the spatial and time-dependent orchestration of head and facial development. In contrast to other craniofacial malformations like clefts or craniosynostoses, branchial arch disease

Branchial arch anomalies in trisomy 18.

Annales de genetique, 1991
The authors report two newborns and one fetus with trisomy 18, who have severe anomalies of the first branchial arch: extreme microtia with imperforate external meatus in two cases, and hemifacial microsomia in a third one. Those cases point to the huge phenotypic variability of the trisomy 18.

Branchial Arch and Oral-Acral Disorders

2001
Abstract Oculo-auriculo-vertebral spectrum (hemifacial microsomia, Goldenhar syndrome) In the 1960s, hemifacial microsomia was defined as a condition affecting primarily aural, oral, and mandibular development. The disorder varies from mild to severe, and involvement is limited to one side in many cases, but bilateral involvement is also
