A statistical study was done on the sensorineural component in hearing loss, using 595 patients suffering from Chronic Otitis Media (COM); of these, 195 with monolateral COM were taken into consideration. They presented criteria of valuation which excluded other possible causes of sensorineural hearing loss, such as exposure to acoustic trauma, ototoxic drugs, cardiovascular disease, past head injury and hereditary causes. The contralateral (healthy) ear served as a control. We determined the average sensorineural component in the hearing losses in relation to the age of onset and duration of the disease, examining it in relation to other eventual aural complications such as cholesteatoma. On the basis of the data obtained, we believe that the sensorineural component in hearing loss does not change with respect to the age of onset of COM, but the duration of COM does exert a significant influence.
对595例慢性中耳炎（COM）患者的听力损失中的感音神经性成分进行了一项统计研究；其中，195例单侧COM患者被纳入研究。他们提出了评估标准，排除了感音神经性听力损失的其他可能原因，如接触声学创伤、耳毒性药物、心血管疾病、既往头部损伤和遗传原因。对侧（健康）耳作为对照。我们确定了听力损失中感音神经性成分与发病年龄和疾病持续时间的关系，并将其与其他可能的耳部并发症（如胆脂瘤）进行了比较。根据获得的数据，我们认为听力损失中的感音神经性成分不会随着COM的发病年龄而变化，但COM的持续时间确实会产生显著影响。
