High palate
Elevated palate
HP:0000218
What it means
Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective).
The measuring device for this assessment is described in (Hall JG, Froster-Iskenius UG, Allanson JE, Gripp K, Slavotinek A. 2006. Handbook of Normal Physical Measurements. 2nd edition. Oxford Medical, publishers). A high palate is often associated with a narrow palate. However, a narrow palate can easily give a false appearance of a high palate. Height and width of the palate should be assessed and coded separately. We do not recommend the subjective determination because this term can be overused and applied inaccurately.

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
