Abstract
After a single or modified radical mastoidectomy the hearing of the contralateral ear was followed by pure tone audiometry in 55 patients. In 12 patients a sensorineural--mostly high tone--hearing loss of at least 20 dB was found in the contralateral ear. In six cases this was persistent. The number of patients with hearing loss increased with increasing operation time. The cause of this hearing loss must be the noise of the bone-cutting burr.
摘要
在55例患者接受单次或改良根治性乳突切除术后，通过纯音听力测定法对其对侧耳的听力进行了跟踪监测。在12例患者中，发现对侧耳存在感音神经性听力损失，多数为高音调损失，至少20分贝。其中6例为持续性损失。听力损失患者的数量随着手术时间的增加而增多。这种听力损失的原因必定是骨钻的噪音。
