作者应用多轨迹断层X线照相法对45名正常成年人90只耳进行了鼓窦入口和鼓窦大小的测量。照相取前后方向和侧面方向进行,断层的间隔为2mm。在前后方向的前庭面上,做了鼓窦入口的上下径和左右径的测量。在前后方向和侧面方向的鼓窦面上,测量了鼓窦的上下径、左右径和前后径。测量结果:鼓窦入口的上下径为7.2mm(±1.37),而左右径为6.7mm(±1.27)。男性
The authors used multichannel tomography to measure the size of the drum sinus entrance and the size of the sinuses in 90 ears of 45 normal adults. Photograph taken before and after the direction and side direction, the fault interval of 2mm. On the vestibular surface in the anteroposterior direction, measurements of the upper and lower diameter and the diameter of the right and left of the entrance to the drum were made. The anteroposterior diameter, right and left diameter and anteroposterior diameter of the sinuses were measured on the surface of the sinuses in the anteroposterior and lateral directions. Measurement results: The diameter of the drum sinus entrance was 7.2 mm (± 1.37) while the diameter of the left and right was 6.7 mm (± 1.27). male
