Hallermann-Streiff syndrome: a review.

The Hallermann-Streiff syndrome is characterized by dyscephaly, hypotrichosis, microphthalmia, cataracts, beaked nose, micrognathia, and proportionate short stature. Cause is unknown; sporadic occurrence is the rule. Data presented in this review include the characteristics of pregnancy, growth and development, principal manifestations, radiographic and ophthalmological characteristics, and the results of cephalometric study. Potential complications in the syndrome are related to the narrow upper airway associated with the craniofacial configuration. Severe complications may include early pulmonary infection, respiratory embarrassment, obstructive sleep apnea, and anesthetic risk. Topics for future study are suggested.
