IPSHL是近年来才从流行病学和听力学角度命名的病,可分为与年龄有关的二型,即婴幼儿型和成年型,前者的特征迄今甚少报道,该作者对42名患儿进行了临床、听力学特征、血液化学改变及其与肝、肾、甲状腺功能和贫血的联系进行观察,患儿中已除外先天遗传性和其它已知病因聋,按公认标准确诊(双耳受累的进行性聋、病因不明),根据患儿发病年龄分为:1组为6岁以下,27例;2组7～14岁,15例,两组中无明显性别差异,全部患儿均接受纯音听阈、鼓室压、镫骨肌声反射、重振、适应和Bekesy听力计扫描。为了解听力减退的发展速度,几乎每2月复查一次听阈,至少随访5年。根据耳聋进展速度,分为快(1年内听
IPSHL is an epidemiological and audiological nomenclature in recent years. It can be divided into age-related type II, infants and adolescents. The characteristics of the former are seldom reported so far. The authors evaluated 42 children Clinical, audiological features, blood chemistry changes and their association with liver, kidney, thyroid function, and anemia were observed. Children with congenital hereditary and other known causes of deafness were diagnosed according to accepted criteria (binocular involvement Of the deaf, the cause is unknown), according to the age of onset of children are divided into: 1 group of 6 years of age, 27 cases; 2 groups of 7 to 14 years old, 15 cases, no significant gender differences between the two groups, all children were accepted Pure tone threshold, tympanic pressure, tarsal muscle acoustic reflex, revitalization, adaptation and Bekesy audiometer scanning. To understand the rate of hearing loss, the hearing threshold is reviewed almost every February for at least 5 years. According to the speed of deafness, divided into fast (1 year to listen
