Therapeutic Effect of Tympanoplasty on Patients with Chronic Otitis Media with Tinnitus and Influencing Factors.

Objective • This research was conducted to investigate the therapeutic effects of tympanoplasty on patients with chronic otitis media with tinnitus and analyze the possible influencing factors for patient prognosis. Methods • This is a pre-post control group study, 86 patients with chronic otitis media were included as the subjects and enrolled into tinnitus group (n = 46) and the non-tinnitus group (n = 40). All patients underwent tympanoplasty under microscope or ear endoscopy. A tinnitus severity and efficacy assessment scale was employed for the evaluation of the severity of tinnitus among the subjects. In addition, tinnitus handicap inventory (THI) was utilized to evaluate disease alleviation. Results • Before treatment, the proportions of the patients with tinnitus at grades I, II, III, IV, and V amounted to 15.22%, 32.61%, 21.74%, 17.39%, and 13.04%, respectively, while they were 30.43%, 45.65%, 13.04%, 8.71%, and 2.17%, respectively 3 months after treatment (P < .05). THI scores for the patients in the tinnitus group before and 3 months after treatment amounted to 17.96 ± 3.66 and 16.21 ± 3.29, respectively (P < .05). After treatment, the air conduction (AC) and bone conduction (BC) thresholds and air-bone gap (ABG) of the two groups apparently declined (P < .05). No statistical significance was detected in the differences in disease classification, disease courses, and whether an electric drill was used among the patients between effective and invalid groups (P > .05). Conclusion • To some extent, tympanoplasty alleviated tinnitus among patients with chronic otitis media and promoted the restoration of hearing. Hence, it is worthy of application in clinical treatment. [ABSTRACT FROM AUTHOR]
