A high-arched palate (also termed high-vaulted palate) is where the palate is unusually high and narrow. It is usually a congenital developmental feature that results from the failure of the palatal shelves to fuse correctly in development, the same phenomenon that leads to cleft palate . [ 1 ]
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Facial deformities with Smith-Fineman-Myers syndrome. SFMS affects the skeletal and nervous system. This syndrome's external signs would be an unusual facial appearance with their heads being slightly smaller than average, a narrow face (clinically known as dolichocephaly), a large mouth with a drooping lower lip that is held open, protruding upper jaw, widely spaced upper front teeth, an ...
Other features frequently associated with VWS include hypodontia in 10-81% of cases, narrow arched palate, congenital heart disease, heart murmur and cerebral abnormalities, syndactyly of the hands, polythelia, ankyloglossia, and adhesions between the upper and lower gum pads. [3]
Narrow face is a dysmorphic feature in which its width is abnormally reduced (upper and lower face width less than 2 SD below the mean subjectively, or apparent reduction of the width of the upper and lower face objectively).
Individuals affected by Fryns-Aftimos syndrome may also present with a broad nose that has a large tip and prominent root, a ridged metopic suture, arched eyebrows, a shoulder girdle muscle bulk and progressive joint stiffness, a cleft lip or palate, hallux duplex (a toe deformation), [6] microcephaly, heart and renal tract abnormalities; all ...
Other physical abnormalities associated with Carpenter syndrome include extra digits. Extra toes are more commonly seen than fingers. Often both the toes and fingers are webbed, a process that occurs before the sixth week gestational period. Often their digits will be abnormally short, and the fingers are commonly missing an interphalangeal joint.
Cranial sutures. A defining characteristic of Crouzon syndrome is craniosynostosis, which results in an abnormal head shape.This is present in combinations of: frontal bossing, trigonocephaly (fusion of the metopic suture), brachycephaly (fusion of the coronal suture), dolichocephaly (fusion of the sagittal suture), plagiocephaly (unilateral premature closure of lambdoid and coronal sutures ...
