对642例慢性化脓性中耳炎（COM）或中耳瘤（CHL）患者进行了年龄因素对鼓室成形术前后听力的影响的研究。分析的重点是听力结果和年龄之间的相关性，为每种疾病和类型的鼓室成形术。通过计算回归线评价数据，主要使用二阶多项式回归分析。与老年人的生理性听力损伤（老年性耳聋）相比，年轻患者的平均空气和骨导阈值（PTA）明显较差，并随年龄增长而增加。患者的空气和骨传导PTA和正常数据（空气传导）的回归线在30岁后彼此分离，听力损害随着年龄的增长逐渐加速。然而，尽管个体患者的听阈分布广泛，但各年龄组的气传听力差均值几乎相同。这在接受III型或IV型鼓室成形术的患者中比I型鼓室成形术的患者更占主导地位，并且在COM患者中比CHL患者更占主导地位。因此，在慢性炎性耳部疾病患者中，唇腭裂功能似乎随着年龄的增长而逐渐恶化。因此，慢性中耳炎患者应建议在早期接受鼓室成形术。
The effects of aging on the preoperative and postoperative hearing results of tympanoplasty were assessed in 642 patients with chronic suppurative otitis media (COM) or cholesteatoma (CHL). Analysis focused on the correlation between hearing results and age for each disease and type of tympanoplasty. Data were evaluated by calculating the regression line, mainly using second order polynomial regression analysis. Averaged air and bone conduction thresholds (PTA) in patients were appreciably poorer in younger patients and increased with age, compared with physiological hearing impairment in old age (presbyacusis). Regression lines for PTA of air and bone conduction in patients and for normal data (air conduction) separated from each other after the age of 30 and hearing impairment gradually accelerated with age. Means of air-borne gap, however, were almost the same in each age group, though hearing thresholds in individual patients were distributed widely. This was more dominant in patients who had undergone type III or IV tympanoplasty than those with type I tympanoplasty, and in patients with COM than with CHL. Labyrinthine function thus appears to be gradually aggravated with age in patients with chronic inflammatory ear disease. Patients with chronic otitis media should be thus recommended to undergo tympanoplasty at an early age.
