악안면 골격 유형에 따른 인두크기에 관한 연구

A STUDY OF THE PHARYNGEAL SIZE IN THE SKELETAL PATTERNS(A CEPHALOMETRIC EVALUATION)

This study was performed to compare the size of pharynx, the soft palate, the hyoid bone according to the horizontal and vertical classification of the jaws. The samples of this study were 68 malocclusion patients(l9 men and 49 women) over 18 years old. The lat. cephalometric radiographs were taken and the distance and angle of the craniofacial skeleton, soft palate and upper airway were measured and evaluated statistically. The results were as follows. 1. In the horizontal classification of the jaws according to ANB to angle, 1) The size of orpharynx of class II malocclusion was smaller than that of the Class III groups. 2) There was difference in the size of nasopharynx between the Class I, Class II, Class III groups. 3) The position of hyoid bone in Class III malocclusion was more anterior and superior position than that of the Class I and Class II groups. 4) There was no difference m the size of soft palate between the Class I, Class II, Class III, groups. 2. There was no difference in the size of pharynx, the soft palate, the hyoid bone according to vertical classification of the jaws.
