Children with secretory otitis who, during the period from 1970 through 1975, had been treated with adenoidectomy and insertion of ventilating tubes were reexamined three to eight years after treatment and, again, ten to 16 years after treatment. The changes of the tympanic membranes were analyzed with regard to the occurrence of attic retractions and changes of the pars tensa of the membranae tympani. At the first follow-up examination, varying degrees of attic retractions were found in 37% of ears and, at the second follow-up examination, in 27% of ears. This general improvement was mainly due to normalization of the slight retractions, whereas the frequency of severe retractions increased. Pathology of the pars tensa of the membranae tympani was found in 57% of ears at the first examination and comprised the following: tympanosclerosis (19%), tympanosclerosis and atrophy (10%), atrophy (22%), atrophy and pexi (3%), and adhesive otitis (3%). At the second follow-up examination, pathology of the pars tensa of the membranae tympani occurred in 58.05% of ears and was distributed as follows: tympanosclerosis (26%), atrophy and tympanosclerosis (11%), atrophy (14%), atrophy and pexi (5%), adhesive otitis (2%), and sinus cholesteatoma (0.5%).
对1970年至1975年期间接受腺样体切除术和插入通气管治疗的分泌性中耳炎患儿，在治疗后三至八年以及再次在治疗后十至十六年进行复查。分析鼓膜的变化，观察上鼓室回缩的发生情况以及鼓膜紧张部的变化。在第一次随访检查中，37%的耳发现有不同程度的上鼓室回缩，在第二次随访检查中，27%的耳出现上鼓室回缩。这种总体改善主要是由于轻度回缩恢复正常，而重度回缩的频率增加。在第一次检查时，57%的耳发现鼓膜紧张部有病变，包括以下情况：鼓室硬化（19%）、鼓室硬化和萎缩（10%）、萎缩（22%）、萎缩和粘连（3%）以及粘连性中耳炎（3%）。在第二次随访检查时，58.05%的耳出现鼓膜紧张部病变，分布如下：鼓室硬化（26%）、萎缩和鼓室硬化（11%）、萎缩（14%）、萎缩和粘连（5%）、粘连性中耳炎（2%）以及胆脂瘤型中耳炎（0.5%）。
