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]
Craniofacial and other features of LFS include: maxillary hypoplasia (underdevelopment of the upper jaw bone), [9] a small mandible (lower jaw bone) and receding chin, [3] [17] a high-arched palate (the roof of the mouth), with crowding and misalignment of the upper teeth; [5] [7] macrocephaly (enlarged skull) with a prominent forehead, [3] [9 ...
Rare symptoms include microphthalmos (abnormally small eyes), tear ducts in the wrong location and a high-arched palate. [1] Type 1 BPES is distinguished by including premature ovarian insufficiency (POI) in females, which causes menopausal symptoms and infertility in patients as young as 15 years old. [1]
The most often cited MPA, high arched palate, is described in articles as a microform of a cleft palate. [3] Cleft palates are partly attributable to hypoxia. [4] The vaulted palate caused by nasal obstruction and consequent mouth breathing, without the lateralising effect of the tongue, can produce hypoxia at night. [citation needed]
Besides affecting height and limb proportions, people with Marfan syndrome may have abnormal lateral curvature of the spine scoliosis, thoracic lordosis, abnormal indentation (pectus excavatum) or protrusion (pectus carinatum) of the sternum, abnormal joint flexibility, a high-arched palate with crowded teeth and an overbite, flat feet, hammer ...
Common features are a narrow/high-arched palate, posterior bilateral crossbite, hypodontia (missing some teeth), and crowding of teeth. Due to maxillary hypoplasia, people with Crouzon syndrome generally have a considerable permanent underbite .
The palate may be arched excessively (a high palate), because the tongue does not form a suction that would normally shape the palate down further. The palate may have a groove (this may be partially due to intubation early on if it is for an extended period of time) or may be cleft (incompletely formed).
Other characteristics include a cleft or high-arched palate, a long, narrow nose, and dislocated joints. [2] Many infants with RAPADILINO suffer feeding difficulties, as well as diarrhea and vomiting. A combination of poor bone development and nutritional deficiencies can cause slow growth and short stature. [2]
