Many studies have been trying to correlate chronic otorrhea, both in children and in adults, with the sensorineural hearing loss in the affected ear, but have been obtaining contradictory results. This loss might be due to the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All the studies evaluated up to the present date compared the affected ear with the normal contralateral ear. From the digitized archive of otological surgery files of the Department of Otorhinolaryngology, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears. Ears with otorrhea were also compared to ears with dry tympanic perforation of other patients. Ears with suppuration were evaluated for cholesteatoma. The duration of otorrhea was taken into account. The sensorineural hearing threshold was evaluated for the frequencies of 500, 1000, 2000, and 4000 Hz. A total of 98 patients with chronic otorrhea and 60 with dry tympanic membrane perforation were evaluated. From a statistical study, a correlation between sensorineural hearing loss and the chronic otorrhea was observed, in comparison both with contralateral normal ears and with dry perforated ears of other patients. There was no relationship with the duration of suppuration or with whether this was due to cholesteatoma. Sensorineural hearing loss occurs in ears with chronic otorrhea. The duration of otorrhea and the etiology of suppuration did not influence the hearing loss. The great majority of otorrhea cases begin during childhood. |
