A study comparing otoscopy with tympanometry was carried out in 1702 ears in seven- and ten-year-old children. Pneumatic otoscopy in 917 ears showed an 88 per cent agreement with tympanometry. The agreement was better in ears considered normal by the otoscopist than in ears that were considered abnormal. Furthermore, the accuracy of otoscopy was better in the older children than in the younger ones. A procedure employing simple otoscopy in 785 ears gave an 83 per cent agreement, but in about 15 per cent of these ears the examiner felt unable to base his evaluation on certainty. It was found that a middle-ear pressure of -100 mm. H2O correlated with recognizable pathology when pneumatic otoscopy was performed.
一项针对7岁和10岁儿童的1702只耳朵进行的耳镜检查与鼓室导抗图对比研究。917只耳朵的气导耳镜检查结果与鼓室导抗图的一致性为88%。耳镜检查判定为正常的耳朵，其与鼓室导抗图的一致性优于判定为异常的耳朵。此外，年龄较大儿童的耳镜检查准确性优于年龄较小的儿童。对785只耳朵采用简单耳镜检查的方法，一致性为83%，但在其中约15%的耳朵中，检查者认为无法基于确定性进行评估。研究发现，进行气导耳镜检查时，中耳压力为-100毫米水柱与可识别的病变相关。
