老年慢性化脓性中耳炎患者听力学分析

目的 探讨老年慢性化脓性中耳炎患者的听力学特点。方法 回顾性分析68例≥60岁单侧慢性化脓性中耳炎患者的语频（0.5、1.0、2.0、4.0kHz）纯音测听结果、术中所见中耳病变组织特点和听骨链病变情况、病变组织病理检查结果。结果 语频范围内，患耳气导、除4kHz外的骨导阈值均高于对侧耳；胆脂瘤患者与非胆脂瘤患者的气、骨导阈无明显差异；听骨链完好者与破坏者（中断或固定）的气导、2kHz骨导阈值差异具有统计学意义，0.5、1.0、4.0kHz骨导阈值差异不显著。结论 老年慢性化脓性中耳炎患者的听力改变有其独特性，掌握老年慢性化脓性中耳炎患者的听力学特征有助于疾病的诊治。

Audiological analysis of aged patients with chronic suppurative otitis media

Objective To study audiological characteristic of aged patients with chronic suppurative otitis media. Methods The data of 68 aged patients(>60 years old) with unilateral chronic suppurative otitis media were reviewed. Speech frequencies(0.5,1.0,2.0,4.0kHz), air conduction threshold and bone conduction threshold were analyzed. The affected tissue in the middle ear and the damages of the ossicular chain were observed in the operation. Pathological examination was performed on the affected tissue. Results The air conduction threshold and bone conduction threshold at all frequencies but 4kHz of the ears with otitis media were higher than the opposite side .There was no obvious difference of the air or bone conduction threshold between patients with cholesteatoma and without . There were significant divergences in the air conduction threshold between patients with a normal ossicular chain and without, however, no divergences in the bone conduction threshold at 0.5,1.0,4.0kHz were found between the two groups. Conclusions There are individualized audiological changes in aged patients with chronic suppurative otitis media. It is helpful for the treatment of aged patients with chronic suppurative otitis media when the corresponding audiological characteristics are fully understood.
