The aims of this study were to estimate the frequency of hearing loss in children with cerebral palsy (CP), to examine factors associated with hearing loss, and to describe aspects of hearing in a population sample of children with CP and hearing loss.
A systematic review of the international literature was undertaken, and data on the frequency of hearing loss or severe hearing loss were extracted from 14 data sets based on previously devised criteria. Six hundred and eight-five children with CP (406 males, 279 females) born in Victoria, Australia, between 1999 and 2004 were identified from the Victorian Cerebral Palsy Register. Children were included if they had an established post neonatal cause for their CP before the age of 2 years. Additional information was collected on 48 children with documented hearing loss based on a four-tone pure tone average in the better ear.
There was considerable variation in the definitions and proportions of hearing loss (range 4-13%) and severe hearing loss (range 2-12%) reported by CP registries in developed countries. In Victoria, 7% of individuals with CP had bilateral hearing loss of a moderate to profound degree, whereas the subgroup with a severe-profound degree of loss constituted 3% to 4% of the CP population.
These population-based data are likely to more accurately reflect the true frequency of defined hearing loss in children with CP than previous reviews.
本研究旨在评估脑性瘫痪（CP）儿童听力损失的频率，探讨与听力损失相关的因素，并描述听力损失儿童人群样本的听力状况。
对国际文献进行系统综述，根据先前制定的标准，从 14 个数据集提取有关听力损失或重度听力损失频率的数据。从澳大利亚维多利亚州脑瘫登记处中确定了 1999 年至 2004 年间出生的 608 名 CP 儿童（406 名男性，279 名女性）。如果儿童在 2 岁之前有明确的新生儿期 CP 病因，则将其纳入研究。根据较好耳的四个纯音平均值，对 48 名有记录听力损失的儿童进行了额外信息收集。
在发达国家，CP 登记处报告的听力损失（范围 4%-13%）和重度听力损失（范围 2%-12%）的定义和比例存在很大差异。在维多利亚州，7%的 CP 患者有双侧中度至重度听力损失，而重度至极重度听力损失的亚组占 CP 人群的 3%至 4%。
这些基于人群的数据可能比以前的综述更准确地反映 CP 儿童明确听力损失的真实频率。
