To find out the prevalence and etiologies of middle ear disease among deaf children in a school for the deaf.
A total of 162 students with hearing impairment attending a school for the deaf during the school year of 2001-2002 were admitted to this study. The range of age was from 6 to 20 years. The examination consisted of inspection of the auricle and external auditory canal, and otoscopic, audiometric and tympanometric evaluation. School performance was assessed using the results of end-of-year school examination and continuous assessments obtained from the school administration.
The demographic properties of the study group revealed that 81 (60.9%) of children were male and 52 (39.09%) were female. Most of the children (45%) were in the group of 9-13 years of age. On pure tone audiometric evaluation, sensorineural hearing loss (HL) was found in 99 (85.3%) and mixed type HL in 17 (14.6%) of 116 cases. Impacted wax was the most common pathology and was seen in 15 (39.4%) of children. Middle ear diseases were detected in 38 (28.5%) of children with otoscopic examination.
This study shows that hearing impairment and preventable ear diseases are important health problems among the school children for the deaf. It is essential to start the school education early in time and to start using hearing aid before 2.5 year of age.
了解一所聋校中聋儿中耳疾病的患病率及病因。
本研究纳入了2001 - 2002学年在一所聋校就读的162名听力障碍学生。年龄范围为6至20岁。检查包括耳廓和外耳道检查，以及耳镜、听力测定和鼓室图评估。学校表现通过年终学校考试结果和从学校管理部门获得的连续评估进行评估。
研究组的人口统计学特征显示，81名（60.9%）儿童为男性，52名（39.09%）为女性。大多数儿童（45%）年龄在9至13岁组。在116例纯音听力测定评估中，99例（85.3%）为感音神经性听力损失（HL），17例（14.6%）为混合型HL。耵聍栓塞是最常见的病变，在15名（39.4%）儿童中可见。耳镜检查发现38名（28.5%）儿童患有中耳疾病。
本研究表明，听力障碍和可预防的耳部疾病是聋校学童中的重要健康问题。及时尽早开始学校教育并在2.5岁之前开始使用助听器至关重要。
