Abstract
OSAS(obstructive sleep apnea syndrome) is becoming more and more of importance nowadays. Therefore the study concerning OSAS is very important. Most of the studies which have been reported were comparison of upper airway size and change of skeletal class Ⅰ group and skeletal class Ⅲ group respectively. But, most of the showing OSAS have pharyngeal narrowing combined with more or less distinct maxillary and mandibular deficiency. Therefore the aim of this study is to see posterior airway space and hyoid bone position in patients affected by class Ⅱ malocclusion and treated with orthognathic surgery. we measured the lines between selected upper air way landmarks on lateral cephalometric x-ray films of skeletal class Ⅱ 30 persons who had not been operated yet, were within 2 weeks after operation, were 6 months after operation. And we compared them respectively and analyzed them with pairing t-test, pearson correlation coefficient and multiple regression analysis. The results were as follows. First of all, skeletal class Ⅱ group was increased in all the level of PAS, especially PAS(MK) and PAS related to hyoid bone(H-phW, H-PhW(Me-H)) was significantly decreased within 6 months after operation but that was larger than preoperation. And then the PAS was increased after mandibular advancement surgery. While there was no significant correlation between PAS and surgical methods, there was statistical significance between PAS and a number of surgical movement. At last, the hyoid bone was advanced within 2 weeks after operation but relapsed within the follow up period. In the end of the study, it was turned out that PAS was always wider without distinction of the region after the operation and that there was significant correlation between the moving volume of hard tissues and the changing quantity of PAS( ; how much PAS was changed according to the moving degree of hard tissues). After this, to be based on the study, I consider that OSAS demands further study and that it is necessary to do more practical applications to the patients.
