[Stimulation in the treatment of hard palate cleft].

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.
