Cochlear implantation is the most effective method of hearing rehabilitation in a group method in group of patients with severe and profound sensorineural hearing loss. Furthermore, tinnitus is a frequent symptom related to hearing impairment. The aim of this study was to assess severity of tinnitus before and after cochlear implantation.

Material and Methods:
This study included 70 patients (35 women and 35 men), who were implanted. Tinnitus severity was evaluated three times: preoperatively, at activation and one month after implantation. Tinnitus and Hearing Survey (THS), Tinnitus Handicap Inventory (THI) and Tinnitus Functional Index (TFI) were used to assess tinnitus severity. THS and THI adaptation were conducted in the World Hearing Center of the Institute of Physiology and Pathology of Hearing.

The results showed that tinnitus was experienced in 65.7% of patients who were qualified to cochlear implantation. One-sided tinnitus (in the operated ear) was experienced in 54.4% cases and bilateral tinnitus in 45.6%. Hearing impairment was the primary complaint of 93.5% cases. Preoperatively, severity of tinnitus was assessed as moderate (THI M=39.9; SD=23.4; TFI M=38.4; SD=21). Results after one monthly observation suggested mild tinnitus severity (M=25.6; SD=21.9; TFI M=29.2; SD=20.6).

Monthly observation showed that severity of tinnitus after cochlear implantation decreased
