Factors specific to sub-Saharan Africa could have an impact on tympanic membrane perforation characteristics. Obtaining precise information on these characteristics and determinants of hearing loss severity would enable better management.
To determine the relationship between characteristics of tympanic membrane perforation and subsequent hearing impairment.
A cross-sectional study of consenting patients presenting with tympanic membrane perforation was conducted. They were examined using otoendoscopy with a digital camera to obtain precise measurements, followed by pure tone audiometry.
Eighty-six cases of tympanic membrane perforation were included. Mean tympanic membrane perforation proportion was 34.1 ± 18.4 per cent. Medium-sized tympanic membrane perforations were predominant (47.7 per cent). Median tympanic membrane perforation duration was 20 years. Tympanic membrane perforation size was found to be a predictor of hearing loss severity (odds ratio = 2.5, 95 per cent confidence interval = 1.02-6.13, p = 0.04).
Tympanic membrane perforation size was a predictor of hearing loss severity in our setting. Site, duration and aetiology seem to have no impact on hearing loss severity.
撒哈拉以南非洲地区的特定因素可能会对鼓膜穿孔特征产生影响。获取有关这些特征以及听力损失严重程度的决定因素的精确信息将有助于更好地进行管理。
确定鼓膜穿孔特征与随后听力损害之间的关系。
对同意参与的鼓膜穿孔患者进行了一项横断面研究。使用带有数码相机的耳内镜对他们进行检查以获得精确测量结果,随后进行纯音听力测定。
纳入了86例鼓膜穿孔病例。鼓膜穿孔的平均比例为34.1±18.4%。中等大小的鼓膜穿孔最为常见(47.7%)。鼓膜穿孔的中位持续时间为20年。发现鼓膜穿孔大小是听力损失严重程度的一个预测指标(优势比=2.5,95%置信区间=1.02 - 6.13,p = 0.04)。
在我们的研究环境中,鼓膜穿孔大小是听力损失严重程度的一个预测指标。部位、持续时间和病因似乎对听力损失严重程度没有影响。
