盖来氏试验(Gelle’s test)是试验镫骨活动情况的重要方法,通常用音叉试验,但音叉音衰减迅速,改用听力计的骨导耳机做此试验,不但效果较为理想,而且通过不同的操作方法能了解镫骨固定的程度。通常使用的方法有两种,定压测试骨导阈法和骨导阈音消失所需压力法。但临床上尚需正常听骨链及镫骨活动的参考数值,为此我们对20人40只正常耳做了此
The Gelle’s test is an important method to test the movement of the sacrum. The tuning fork is usually used, but the tuning fork attenuates rapidly. To use bone-conduction headphones with an audiometer for this test, not only is the effect satisfactory, but also it is different. The method of operation can understand the degree of fixation of the sacrum. There are two commonly used methods, constant pressure test bone conduction threshold method and bone pressure threshold sound disappeared pressure method. However, we still need a reference value for the normal ossicular chain and zygomatic movement. For this reason, we did this for 40 normal ears of 20 people.
