许多人的研究发现颅骨的变形性骨炎患者常有听力下降,有的相当严重,并逐渐加重。变形性骨炎好发于年龄较大者。为澄清本病患者的听力下降是疾病本身原因,还是单独由年龄增长所造成,作者由100例病人中选出4例资料完整者(具有4～5年定期听力检查资料)与同性别、同年龄正常人听力下降速度进行了对比。结果表明:正常人年龄因素造成听力下降每年0.5dB,而变形性骨炎患者健侧耳听力下降速度与正常人相同,患侧耳下降速度每年大于2dB。因此作者
Many people’s study found that patients with degenerative osteitis of skull often hearing loss, and some very serious, and gradually increased. Deformative osteitis occurs in older people. In order to clarify the patient’s hearing loss is the cause of the disease itself, or alone caused by age, the author selected from 100 patients in 4 patients with complete data (with 4 to 5 years of regular hearing test data) with the same sex, with Normal hearing rate of hearing loss compared.
