Dlx5 regulates regional development of the branchial arches and sensory capsules

Development, 1999
Abstract We report the generation and analysis of mice homozygous for a targeted deletion of the Dlx5 homeobox gene. Dlx5 mutant mice have multiple defects in craniofacial structures, including their ears, noses, mandibles and calvaria, and die shortly after birth. A subset (28%) exhibit exencephaly.

Branchial arch defects and 19p13.12 microdeletion: Defining the critical region into a 0.8 M base interval

American Journal of Medical Genetics Part A, 2011
AbstractWe present a patient with preauricular tags, preauricular and branchial pits, stenosis of the external auditory canals, mild hearing loss, and mild developmental delay who had a de novo 19p13.12 submicroscopic deletion. The size of the deletion was 760‐kb, extending from 15,300,338 to 16,064,271 (hg18; NCBI Build 36.1). Our finding supports the

Hox Genes and the Development of the Branchial Region

1992
One of the key events in early development is positional specification, the process by which initially equivalent parts of a developing structure become different from one another. Once such differences are established the localised production of the substances can occur which eventually causes morphological differences to become apparent in a ...

Endoscope-Assisted Excision of Second Branchial Cleft Cysts Using a Hairline Approach in the Posterior Occipital Region

Journal of Oral and Maxillofacial Surgery, 2014
Second branchial cleft cysts have usually been resected through a prominent incision over the entire protruding zone. The resultant scar can be esthetically displeasing. We report on the endoscope-assisted excision of second branchial cleft cysts by way of a posterior occipital approach.

Embryonic development of the head and neck: Part 2, the branchial region

Head & Neck Surgery, 1979
AbstractThe embryology of the branchial (pharyngeal) region is reviewed in terms of the embryonic pharynx, branchial apparatus and derivatives, tongue, larynx, and trachea. Derivatives of the branchial pouches, grooves (clefts), and arches are analyzed in relation to each other and to the first arch syndrome.

Hox genes and pattern formation in the branchial region of the vertebrate head

Trends in Genetics, 1993
The conservation of molecular mechanisms in evolution has stimulated interest in comparative embryology, and the Hox/HOM-C homeobox complexes are among the best examples of the remarkable conservation between species. An important region associated with Hox patterning is the head, where the evolutionary and molecular studies have reawakened interest in

Branchial Arch Syndromes Relating to the Craniofacial Region And Its Importance in Dentistry

2022
Many syndromes affect the craniofacial region. In most syndromes, there are numerous symptoms in the mouth, head, and neck regions. Individuals with syndromes, who visit the dentist less frequently than healthy individuals who routinely visit the dentist, have features that are unique to their particular conditions.

[The branchial region and its proper role in the morphogenesis of the neck].

Acta oto-rhino-laryngologica Belgica, 1990
The branchial apparatus is a keystone in the embryonic arrangement of the neck region. However the developing cervical region is also under the influence of the fundamental metamerism of the body--the formation of sonites-, which gives origin to the cervical spine, the prechordal space and the anterior cervical area.
