目的观察慢性化脓性中耳炎对感音神经性聋的影响。方法对80例慢性化脓性中耳炎患者进行回顾性分析骨导阈值改变。结果单纯型慢性化脓性中耳炎33例,77.27%的鼓膜穿孔为大于紧张部总面积25%的穿孔,22.73%的鼓膜穿孔为小于或等于紧张部总面积25%的穿孔,双侧和单侧单纯型慢性化脓性中耳炎患者鼓膜穿孔大小相比较,双耳患者中大穿孔占41.4%,单耳患者中大穿孔占6.7%,两组患者鼓膜穿孔大小构成经两独立样本非参数检验有统计学意义。结论慢性化脓性中耳炎可引起感音神经性聋,且中耳病变越重,病程越长,听力下降越明显。
Objective To observe the effect of chronic suppurative otitis media on sensorineural deafness. Methods Eighty patients with chronic suppurative otitis media were retrospectively analyzed for bone conduction threshold changes. Results Thirty-three cases of simple chronic suppurative otitis media, 77.27% of tympanic membrane perforation was larger than 25% of the total area of perforation perforation, 22.73% of tympanic membrane perforation less than or equal to 25% of the total area of perforation perforation, bilateral and unilateral simple Type of chronic suppurative otitis media in patients with tympanic membrane perforation size compared to the large perforation of the ears of patients accounted for 41.4%, large ears perforation accounted for 6.7% of the two groups of patients with tympanic membrane perforation size by two independent samples of non-parametric test was statistically significant . Conclusion Chronic suppurative otitis media can cause sensorineural deafness, and the more severe the middle ear lesions, the longer the duration, the more obvious the hearing loss.
