Experimental animals used was two young dog and two adult dog with normal palate. After midpalatal suture was seperated with rapid palatal expansion device, experimental animals were sacrificed to observe the surrounding maxillary sutures. The following results were obtained. 1. In adult dog, nasoincisive suture was not expanded, while in young dog it was expanded. 2. In adult dog, pterygopalatine suture was hardly expanded, while in young dog it was expanded definitely. 3.
