慢性化脓性中耳炎是一个严重的世界性健康问题。一般认为，听力损失随着穿孔的大小而增加，如果穿孔位于后下象限，则更是如此。本研究旨在检验上述概念的有效性。经机构伦理委员会批准，在斋浦尔SMS医学院进行了一项观察性研究。共研究90例。根据鼓膜穿孔大小将15-50岁的干性鼓膜穿孔患者分为3组：Ⅰ组（0- 9mm）2例，Ⅱ组（9-30 mm）2例，Ⅲ组（>30 mm）2例，每组30例。听力损失计算为500、1000、2000 Hz时听力损失的平均值。将穿孔部位分为前象限穿孔A组、后象限穿孔B组、多象限穿孔C组。在研究结束时，系统地整理数据，并使用事后检验进行分析。年龄组在15至50岁之间，平均年龄为25.6岁。我们的研究发现听力损失与穿孔大小成正比。（p = 0.000，非常显著）。我们还观察到，听力损失更多的后方和多个穿孔比前方穿孔。（p = 0.000，非常显著）。总的来说，这项研究表明穿孔的大小和部位与听力损失的程度之间存在显着的相关性。
Chronic suppurative otitis media is a serious health problem worldwide. It has been a general view that the hearing loss increases with the size of the perforation, more so if it is in the postero- inferior quadrant. The present study is an effort to test the validity of above concepts. With Institutional ethical committee clearance, an observational study was carried at SMS medical college, Jaipur. A total of 90 cases were studied. All cases between the age group 15-50 years with dry tympanic membrane perforations were divided into 3 groups Group I (0-9 mm(2)), Group II (9-30 mm(2)), Group III (>30 mm(2)) with 30 in each group based on size of perforation. Hearing loss was calculated as average of hearing loss at 500, 1000, 2000 Hz. Similarly the site of perforation was grouped as perforation involving anterior quadrant, posterior quadrant and multiple quadrant as Group A, Group B, Group C respectively. At the end of study, data was compiled systematically and analyzed using Post Hoc test. The age group ranges between 15 and 50 years with mean age of 25.6 years. Hearing loss was found to be directly proportional to the size of perforation in our study. (p = 0.000, highly significant). We also observed that hearing loss was more in posterior and multiple perforations than in anterior perforations. (p = 0.000, highly significant). Overall this study has shown significant correlation between the size and the site of the perforation to the degree of hearing loss.
