Pseudohypacusis is a condition in which a hearing loss is exhibited in the absence of any organic disease. The mainstay of diagnosis is a lack of consistency in audiological testing. It is usually easier to diagnose in children than in adults, as children are less able to produce consistently erroneous results on repeated testing. In spite of this, the diagnosis is often missed in children, probably due to a lack of awareness of the condition. We present the findings in ten children seen in the past year. Initially they had average pure tone thresholds of 51.3 db in the right ear and 51.4 db in the left ear. All of the children underwent repeat pure tone audiometry and speech audiometry. In nine cases the speech audiograms confirmed the diagnosis. In one child the speech audiogram was consistent with a mild hearing loss subsequently confirmed as a 30-40 db low frequency sensorineural hearing loss. Following a programme of close follow up and support, the pure tone thresholds returned to within normal limits in nine children and to a level consistent with the clinical impression in the child with a sensorineural loss. None of the children required brain stem evoked response audiograms to confirm the diagnosis.
伪听力减退是一种在没有任何器质性疾病的情况下出现听力损失的病症。诊断的主要依据是听力测试结果缺乏一致性。通常在儿童中比在成人中更容易诊断,因为儿童在重复测试中不太可能持续产生错误结果。尽管如此,儿童中这种病症的诊断常常被漏诊,可能是由于对该病症缺乏认识。我们展示了过去一年中诊治的10名儿童的情况。最初,他们右耳的平均纯音听阈为51.3分贝,左耳为51.4分贝。所有儿童都接受了重复纯音听力测定和言语听力测定。9例中言语听力图证实了诊断。1名儿童的言语听力图与轻度听力损失相符,随后被确认为30 - 40分贝的低频感音神经性听力损失。经过密切随访和支持治疗方案后,9名儿童的纯音听阈恢复到正常范围内,而患有感音神经性听力损失的儿童的听阈恢复到与临床印象一致的水平。没有儿童需要脑干诱发反应听力图来确诊。
