A survey of 1,109 native Indian children in five communities in British Columbia was conducted to determine incidence of middle ear pathologic features and to compare impedance and pure-tone audiometry as hearing screening methods. Survey teams included a public health nurse, two otologists, and two audiologists. On ear, nose, and throat (ENT) otoscopic examination, the incidence of middle ear disease requiring treatment was 12%. Disease was most prevalent in the preschool- and primary school-aged children. Pure-tone audiometry yielded 62% normal and 19% abnormal results. Nineteen percent of the children could not be tested by this method. Impedance audiometry yielded 54% normal and 38% abnormal results on the stringent criteria used to define the parameters of normality. Eight percent of the children could not be tested. Since there was a high incidence of middle ear pathologic features in the preschool group of children who could not be successfully evaluated by pure-tone audiometry, it is suggested that further investigation of impedance audiometry be undertaken in order to define parameters that will provide the most reliable referral criteria.
对不列颠哥伦比亚省五个社区的1109名印度原住民儿童进行了一项调查，以确定中耳病理特征的发生率，并比较阻抗测听法和纯音听力测定法作为听力筛查方法的效果。调查团队包括一名公共卫生护士、两名耳科医生和两名听力学家。在耳、鼻、喉（ENT）耳镜检查中，需要治疗的中耳疾病发生率为12%。该疾病在学龄前和小学年龄段的儿童中最为普遍。纯音听力测定法得出62%的结果正常，19%的结果异常。19%的儿童无法通过这种方法进行测试。在用于定义正常参数的严格标准下，阻抗测听法得出54%的结果正常，38%的结果异常。8%的儿童无法进行测试。由于在无法通过纯音听力测定法成功评估的学龄前儿童组中，中耳病理特征的发生率较高，因此建议对阻抗测听法进行进一步研究，以确定能提供最可靠转诊标准的参数。
