Short hard palate
HP:0010290
What it means
Distance between the labial point of the incisive papilla to the midline junction of the hard and soft palate more than 2 SD below the mean (objective) or apparently decreased length of the hard palate (subjective).
Objective measurement of the hard palate requires special instrumentation [Hall JG, Froster-Iskenius UG, Allanson JE, Gripp K, Slavotinek A. 2006. Handbook of Normal Physical Measurements. 2nd edition. Oxford Medical, publishers]. A short hard palate may be associated with velopharyngeal incompetence.
