[Stimulation in the treatment of hard palate cleft]. / La stimulation dans le traitement de la fente du palais dur.

It is rare to observe a cleft of the hard palate after operation for secondary cleft palate. Four such cases were treated using a plate developed by the author and corrector-stimulatory apparatuses. Total recovery was obtained in one case, and marked pre-operative reduction in the palatal cleft in two patients. Treatment was ineffective in the fourth case, a patient who had previously undergone five operations. Treatment by stimulation was given for periods between 14 months to 4 years.

[Mandible magnitude in Crouzon syndrome]. / Wielkosc zuchwy w zespole Crouzona.

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.
