成人头颅外伤后的听力损失已有很多报道,而儿童的报道较少,且外伤后是否会发生蜗后病变已引起不少作者的重视。本文目的是观察儿童头颅外伤后耳部和听力损伤的情况。观察对象分为四组:A组为1977～1978年因急性钝性头颅外伤住院治疗的16岁以下61例病儿,平均年龄9.7岁。只要患儿情况许可且合作,均于伤后即刻进行临床检查,包括听力检查,其中59例伤后随访6～12个月。B组为1971～1975年因头颅钝性外伤住院治疗的16岁以下190例中进行随访观察的138例患儿,受伤时平均年龄为8.1岁,伤后平均随访时间是4.7年。59名16岁以下无头颅外伤的健康儿童作A组对照组,平均年龄10.7岁。29名16～19岁的健康人加上A组对照组中的59名儿童组成B组对照组,平均年龄13岁。
There have been many reports of hearing loss after head injury in adults, and the reports of children are few, and whether or not post-traumatic lesions will occur after trauma have aroused the attention of many authors. The purpose of this paper is to observe the situation of ear and hearing impairment in children with head trauma. Subjects were divided into four groups: Group A was hospitalized in 1977 to 1978 due to acute blunt traumatic head injury in children aged 16 and below 61 cases, with an average age of 9.7 years. As long as the circumstances of the children permission and cooperation, were immediately after the injury clinical examination, including hearing tests, of which 59 cases were followed up for 6 to 12 months. In Group B, 138 children were followed up for 190 years under the age of 19 from hospitalized patients with head traumatic blunt trauma from 1971 to 1975. The mean age at injury was 8.1 years. The average follow-up time after injury was 4.7 years. Fifty-nine healthy children under 16 years of age without craniocerebral injury were selected as control group A with the mean age of 10.7 years. Thirty-nine healthy children aged 16-19 years plus 59 children in control group A comprised group B control group with a mean age of 13 years.
