Tympanic membrane perforation is one of the most common causes of hearing impairment. In this study, we aim to evaluate the effect of duration and size of perforation and its correlation with hearing loss in patients of chronic suppurative otitis media.
This is a prospective study of 100 patients with mild-to-moderate hearing loss up to 60 dB. A complete medical history was taken each time before a thorough examination and test evaluation. Depending on the size, location, and length of the perforation, all patients with dry tympanic membrane perforation who did not have active middle ear disease at the time of presentation were evaluated for hearing loss.
A higher proportion of hearing loss was found in the lower age groups. A significant relationship was found between hearing loss and perforation diameter ( P = 0.023). A higher proportion of hearing loss was observed at higher perforation diameters. Duration of perforation showed a significant positive correlation between air conduction and duration of perforation ( r = 0.205, P = 0.041). Subjects were more likely to have air conduction falling into the 25-40 category compared to <25 at lower age, higher duration, and smaller size.
Hearing loss showed that most subjects had air conduction in the range of 25-40 (66%). If the perforation occurs at a lower age, hearing loss is more likely. Hearing loss was significantly associated with the diameter of the perforation ( P = 0.023).
鼓膜穿孔是听力障碍最常见的原因之一。在本研究中，我们旨在评估慢性化脓性中耳炎患者穿孔的持续时间和大小及其与听力损失的相关性。
这是一项针对100例听力损失轻度至中度（高达60分贝）患者的前瞻性研究。每次在进行全面检查和测试评估之前都要采集完整的病史。根据穿孔的大小、位置和长度，对所有鼓膜干性穿孔且就诊时无中耳活动性疾病的患者进行听力损失评估。
在较低年龄组中发现听力损失的比例较高。发现听力损失与穿孔直径之间存在显著关系（P = 0.023）。在穿孔直径较大时观察到听力损失的比例较高。气导与穿孔持续时间之间存在显著正相关（r = 0.205，P = 0.041）。与年龄较小、穿孔持续时间较长和穿孔尺寸较小且气导<25的受试者相比，受试者的气导更有可能落在25 - 40范围内。
听力损失表明大多数受试者的气导在25 - 40范围内（66%）。如果穿孔发生在较低年龄，则听力损失的可能性更大。听力损失与穿孔直径显著相关（P = 0.023）。
