한국정상성인에 있어서의 상악동용적의 크기에 관한 연구

Abstract

To prepare the basic data for the investigation of the maxillary sinus, authors estimated the volume of the maxillary sinus in normal Korean adults (male 33, female 22) whose range of age was from 18 to 79. An regression equation, V=O. 4099·S·L- J. 45(r= 0.96, p<O.OO, was obtained from 10 dry skulls measuring their real volume with a use of Waters' view and PNS lateral view using a planimeter. The volume of the maxillary sinus was estimated after substituting the value of the surface area (S) and the length (L) measured for the equation of V=O. 4099·S·L-1. 45. The obtained results were as followed. 1. In Kcrean adults, the mean volume of the' maxillary sinus was 13. 45±4. 31cm3 in male and 11.89±4. 20em3 in female, and 12. 82±4. 20em3 in both sexes, But the difference between male and female was not statistically significant. 2. Among the obtained volumes of maxillary sinuses, the largest was 25. 41em3 and the smallest was. 6.24cm3•
