Chronic otitis media (COM) is characterized by conductive hearing loss, possible perforation of the tympanic membran and periodic or permanent otorrhea. The aim of the study is to analyze the results of hearing tests in patients operated on for COM. The least beneficial effect of the performed reconstruction was observed in patients with damage to the stapes suprastructure. It was found that the mean bone conduction before surgery was 31.8 dB, it did not differ 6 months after surgery but it got worse in long-term follow-up at 43.4 dB. The air-bone gap before surgery averaged 26.4 dB, and it decreased significantly in the postoperative period at 17.6 dB. The air-bone gap level remained at a similar level in remote control. In groups I and II of the proposed division of speech audiometry, the difference in maximum speech comprehension in remote control did not differ significantly between the healthy and operated ear. Only in group III the difference was significant: 77.1% vs. 47.1% in the healthy and treated ears, p=0.02. The performed surgery best improved the speech comprehension in group II, where the best attained percentage of speech comprehension increased from 72.9% (pre-operative) to 95.2% at the end of the follow-up, p=0.011. The passage of time in chronic otitis media with damage to the ossicular chain has a negative impact on sensorineural hearing loss. Reoperati ; on worsens long-term hearing test results compared to surgery performed for the first time. Middle ear reconstructive surgery offers the maximum improvement in speech comprehension
