Craniofacial-deafness-hand syndrome (CDHS) is an autosomal dominant disorder, described in one family to date, characterized by characteristic facial features (flat facial profile with normal calvarium, hypertelorism, small downslanting palpebral fissures, hypoplastic nose with button tip and slitlike nares, small ''pursed'' mouth), profound sensorineural deafness, and ulnar deviations and contractures of the hand. CDHS is thought to be an allelic variant of Waardenburg syndrome (see this term) that can be distinguished from the latter by its imaging findings and distinct facial features.

Abnormally small dimension of the Maxilla. Usually creating a malocclusion or malalignment between the upper and lower teeth or resulting in a deficient amount of projection of the base of the nose and lower midface region.
