The effect of a conductive hearing loss secondary to serous otitis media in children with sensorineural hearing loss was seen to be an increase in threshold and in one case a decrease in speech discrimination. The diagnosis of the conductive component can be made by means of measurement of impedance, middle ear pressure, the recording of a tympanogram and otoscopy. It is likely that a conductive component can lead to delay in the diagnosis of an underlying sensorineural hearing loss in some children which could result in exacerbation of speech and language deficits. Correction of the conductive component can convert a profound hearing loss to a severe hearing loss, or a severe hearing loss to a moderate hearing loss, and it may also increase speech discrimination.
浆液性中耳炎继发的传导性听力损失对患有感音神经性听力损失的儿童的影响表现为阈值升高，在一个病例中言语辨别力下降。传导性成分的诊断可通过测量阻抗、中耳压力、记录鼓室图和耳镜检查来进行。在一些儿童中，传导性成分可能导致潜在的感音神经性听力损失诊断延迟，进而可能导致言语和语言缺陷加剧。纠正传导性成分可将极重度听力损失转变为重度听力损失，或将重度听力损失转变为中度听力损失，还可能提高言语辨别力。
