title: [Mandible magnitude in Crouzon syndrome].
abstract: The authors describe Crouzon syndrome in 5 patients aged 9, 10, 13, 40 and 43 years. Typical image of Crouzon syndrome has been found in the woman and three children and its abortive form--in the man. The authors present their own studies on branch height, length of the body of the mandible and the angle value of the mandible according to the Costaras-Volarich and Pruzancky method in their paper. The ratio of the branch to the body is 1:1 in all patients under examination and it is not equal to the normal ratio of 2:3. The angle of the mandible is also greater than the normal value. The authors put forward a hypothesis that pseudomesioclusion in the sick with Crouzon syndrome can be conditioned not only by maxilla dysplasia but also by excessive height of the branch and increased angle value of the mandible basing on their own observations. This hypothesis, however, exact further radiocephalometric studies and close cooperation of obstetricians, paediatricians and orthodontists.
