Sensorineural hearing loss was studied in 874 chronically infected ears and was found to occur more frequently in cases of cholesteatoma and in the presence of discharge. Sensorineural hearing loss is not dependent on the type of causative microorganism. Older patients exhibited sensorineural hearing loss more often than did younger patients, this disorder being more common in affected ears than in control ears (the contralateral ear in unilateral cases).
对874只慢性感染耳进行了感音神经性听力损失研究，发现其在胆脂瘤病例和有耳漏的情况下更频繁发生。感音神经性听力损失不取决于致病微生物的类型。老年患者比年轻患者更常出现感音神经性听力损失，这种疾病在患耳中比在对照耳（单侧病例中的对侧耳）中更常见。
