Author's Abstract A considerable difference of opinions exists in regard to the maldevelopment of the palate after surgery of cleft palate. In order to solve these problems 20 young growing dogs were used. Five of them were growing dogs were used. Five of them were unoperated on as control, and the remaining ani- mals on which unilateral surgical procedure was performed on their left palate. Ten months after operation, these animals were sacrificed, and a comparison was made between the hard palate of the operated and the unoperated, and the fol- lowing results were obtained. 1) There was no remarkable asymmetry on the palatal bone in the cases which had surgery in the form of raising mucoperiosteal flap and partial removal of the bony palate. 2) In addition to the above surgical procedu. res, a small strip of tissue was removed from the median edge of the flap and this flap was displa. ced medially to cover the bone defect. In this case, maldevelopment of the palatal bone was ob- served on the operated side. 3) For the prevention of such a maldevelop- ment of the palatal bone, autograft of the cartilage was used on the bone cleft, and it proved to be very effective. But application of heterografting (using silicon rubber) to the same case was not fruitful.
