Aim. Tinnitus represents a serious problem and it considerably influences the quality of life. In many afflicted patients, it leads to neurotisation or even to suicide.
Methods. At the Ear-Nose-Throat (ENT) Clinic of the 3rd Medical Faculty of the Charles University in Prague the intra-ear catheter (IEC) was implanted to 13 patients. This catheter was used in patients with chronic tinnitus whose previous therapyæmost often polypragmaticæwas unsuccessful. All the patients undertook a full ENT check, including the pure tone and speech audiometry. Following, also the intensity (in decibels, dB) and frequency (in Hertz, Hz) of the tinnitus was determined. Within this project, we worked only with the patients who suffered from the maskable, i.e. cochlear tinnitus. IEC was implanted during a short general anesthesia. Two remedies were used: 1) for patients with good hearing, we used corticoid; 2) for patients with bad hearing or for those who were even deaf, we used Gentamycin. Continuous treatment continued for 2 weeks.
Results. As the decisive criterion, the subjective evaluation by patient was taken. Furthermore, also the intensity and its decrease were measured. In 10 patients from the cured group, the decrease in tinnitus of 2 degrees or more was observed. The decrease in tinnitus of 20 dB and more was observed in 9 (70%) patients. In 2 (15%) more patients, it was <20 dB. In 2 (15%) patients, the tinnitus remained unchanged. Furthermore, the correspondence between the subjective and objective evaluation of tinnitus was evaluated. The correspondence was confirmed in 9 (70%) cases.
Conclusion. Our results were achieved within a small sample, however, their positive effect is convincing.. We can say that the targeted application of medicine directly into the inner ear takes up an important place in the treatment of inner ear illnesses.
