Sonometric data on the Eustachian tube opening response to swallowing and to pressing the mandible down were evaluated in 51 normal ears and 62 ears with chronic disease. Testing with a narrow-band noise which was centered on 7 and 8 kHz gave the best results. The limit for a positive response was set at 3 dB, and of the normal ears, 80% showed a positive response in a short routine test. The data correlated reasonably well with surgical results. If test results point to tubal insufficiency, measures should be taken to prevent the formation of retraction pockets.
对51只正常耳朵和62只患有慢性疾病的耳朵进行了声测数据评估，以了解咽鼓管开口对吞咽和下颌下压的反应。使用以7千赫和8千赫为中心的窄带噪声进行测试，效果最佳。阳性反应的阈值设定为3分贝，在常规短时间测试中，80%的正常耳朵显示出阳性反应。这些数据与手术结果有较好的相关性。如果测试结果表明咽鼓管功能不全，应采取措施防止形成内陷袋。
