Cleft chins are common among people originating from Europe, the Middle East and South Asia. [21] There is a possible genetic cause for cleft chins, a genetic marker called rs11684042, which is located in chromosome 2. [22] In Persian literature, the chin dimple is considered a factor of beauty and is metaphorically referred to as "the chin pit ...
Cleft chin: Smooth chin [13] Freckles: No freckles [7] [14] Wet-type earwax: Dry-type earwax [10] [15] Roman nose: No prominent bridge [16] Marfan syndrome: Average body proportions and connective tissue [17] Huntington's disease: No nerve damage [18] Normal mucous lining Cystic fibrosis [19] Photic sneeze reflex: No light-induced sneeze reflex ...
A bifid nose (also known as cleft nose) is an uncommon congenital malformation which is characterized by the presence of a cleft between the two nostrils of the nose. [1] It is the result of a disturbance during embryological nose development. [2] It is part of the Tessier classification for craniofacial clefts. [3]
Pierre Robin sequence [a] (/ p j ɛər r ɔː ˈ b æ̃ /; [3] abbreviated PRS) is a congenital defect observed in humans which is characterized by facial abnormalities.The three main features are micrognathia (abnormally small mandible), which causes glossoptosis (downwardly displaced or retracted tongue), which in turn causes breathing problems due to obstruction of the upper airway.
Tessier number 1, 2, 12 and 13 are the paramedian clefts. These clefts are quite similar to the midline clefts, but they are further away from the midline of the face. Tessier number 1 and 2 both come through the maxilla and the nose, in which Tessier number 2 is further from the midline than number 1. Tessier number 12 is in extent of number 2 ...
The following list comprises the most common symptoms people with this disorder exhibit: [2] Severe micrognathia; Thorax in the shape of a bell; Cleft palate; Neonatal respiratory difficulties; Rib gaps; Common (but not the most) symptoms include: External auditory canal atresia; Hearing loss; Failure to thrive; Glossoptosis; Intellectual ...
Treacher Collins syndrome (TCS) is a genetic disorder characterized by deformities of the ears, eyes, cheekbones, and chin. [5] The degree to which a person is affected, however, may vary from mild to severe. [5] Complications may include breathing problems, problems seeing, cleft palate, and hearing loss. [5]
