A prospective study on the dynamics of tympanic membrane atelectasis during the treatment for glue ear was performed in a sample of 115 ears of 83 children aged between one and 11 years. The progression in the degree of pars tensa atelectasis was analysed in relation to six potentially relevant factors. Multivariate analysis showed that the factor with the most predictive value on the progression of the pars tensa retraction was the grade of atelectasis at initial detection (p < 0.0001). The use of grommets did not have any significant influence on the outcome grade of atelectasis. There was an association between previous grommet insertion and localized retractions in the inferior segment of the pars tensa (p < 0.0001). However, localized retractions in the postero-superior quadrant were not associated with previous grommet insertion (p < 0.02). Although the hearing thresholds of atelectatic ears were significantly worse than normal ears especially at 4 kHz (p < 0.006), the difference was less than 5 dB.
对83名年龄在1至11岁儿童的115只耳朵进行了一项关于胶耳治疗期间鼓膜萎缩动态变化的前瞻性研究。分析了紧张部萎缩程度的进展与六个潜在相关因素的关系。多变量分析表明，对紧张部回缩进展预测价值最高的因素是初次检测时的萎缩程度（p<0.0001）。鼓膜切开置管术的使用对萎缩的最终程度没有任何显著影响。既往鼓膜切开置管术与紧张部下段局限性回缩之间存在关联（p<0.0001）。然而，后上象限的局限性回缩与既往鼓膜切开置管术无关（p<0.02）。尽管萎缩耳的听力阈值明显比正常耳差，尤其是在4kHz时（p<0.006），但差异小于5dB。
