Abstract

On the basis of the comparative studies the authors have found a
reduced lower jaw in persons with Down syndrome. This reduction as
compared to the lower jaw in normal persons is greater with respect to the ramus height than with respect to the length and width of the lower jaw. The angle of the lower jaw is greater in mongoloids, i.e. more obtuse, while the vertical possition and its inclination are unchanged. The authors maintain that in persons with Down syndrome a low position of the ear and most probably macroglossity result from the retarded development of the lower jaw, or that a low position and macroglossity are relative with respect to the reduced volume of the oral cavity.
