Abstract

|
In order to study on the pneumatization of the temporal bone, 114 cases of healthy young adults were chosen and roentgenograms of temporal bone on Law´s and Stenvers´ view were taken. Surveys were made statistically on the distribution of types of pneumatization(classified in 6 grades) and cell structures.
Following results were obtained.
1. The over-all distribution of types of pneumatization is 89.03 ± 2.06%o for the we11-developed type and 10.96:t2.06% for the underdeveloped type. Attention must be directed to the fact that the well-developed cases were seen in high per centage and that not a single case of the highly underdeveloped grade could be seen in this study.
2. When the pneumatization of the right and left temporal bones were compared, 90.35 ± 2. 76 % of the cases revealed same types and 59.64 ±4.59 % of the cases revealed same grades between the two. Among those having same. types on both -sides, 91.17 ±3.43 % of cases belonged to the well-developed type.
3. The cell structures of the pneumatization of the temporal bone were regular in 60.08±3.24% and irregular in 39.91±3.24%.
4. When the cell structures of the right and left temporal bones -were compared 78.06±3.87%o of cases were of same structures.
5. Analytical study of the components of the cell structures revealed the presence of the medium-sized cells, the presence of medium degree iii cell-arrangement, and the presence of the thin , cell wall in high per centages respectively.
