Many studies have attempted to correlate chronic otorrhea in children and in adults with the sensorineural hearing loss in the affected ear, with contradictory results. This loss might be the result of the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All studies evaluated to date compared the affected ear with the normal contralateral ear. From the digitized archive of otologic surgery files of the Department of Otorhinolaryngology at Santa Casa de São Paulo School of Medical Sciences, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears. Ears with otorrhea were also compared with ears of other patients with dry tympanic perforation. Ears with suppuration were evaluated for cholesteatoma. The duration of otorrhea was considered. The sensorineural hearing threshold was evaluated for the frequencies of 500, 1,000, 2,000, and 4,000 Hz. A total of 98 patients with chronic otorrhea and 60 with dry tympanic membrane perforation were evaluated. A correlation between sensorineural hearing loss and chronic otorrhea was observed when compared with both contralateral normal ears and dry perforated ears of other patients. No relationship between hearing loss and the duration of suppuration or cholesteatoma was found. Sensorineural hearing loss occurs in ears with chronic otorrhea. The duration of otorrhea and the etiology of suppuration did not influence the hearing loss.
许多研究试图将儿童和成人的慢性耳漏与患耳的感音神经性听力损失联系起来，但结果相互矛盾。这种听力损失可能是所涉及细菌的潜在毒性、炎性细胞因子的作用或耳毒性抗生素的持续使用所致。迄今为止所有评估的研究都是将患耳与对侧正常耳进行比较。从圣保罗医学院圣卡塔琳娜医院耳鼻喉科耳科手术档案的数字化存档中，对慢性耳漏患者的耳朵进行了视觉评估，并与对侧正常耳进行比较。耳漏的耳朵也与其他鼓膜干性穿孔患者的耳朵进行了比较。对化脓性耳朵评估是否存在胆脂瘤。考虑了耳漏的持续时间。评估了500、1000、2000和4000赫兹频率下的感音神经性听力阈值。共评估了98例慢性耳漏患者和60例鼓膜干性穿孔患者。与对侧正常耳和其他患者的干性穿孔耳相比，观察到感音神经性听力损失与慢性耳漏之间存在相关性。未发现听力损失与化脓持续时间或胆脂瘤之间存在关联。慢性耳漏的耳朵会出现感音神经性听力损失。耳漏的持续时间和化脓的病因并未影响听力损失。
