Objective: To summarize the curative effect of eustachian tube in the treatment of chronic catarrhal otitis media. Methods: 39 cases of chronic otitis media with otitis media were treated with Eustachian catheter, 56 ears. Results: The average hearing loss (HL) before treatment was 52.4 ± 7.2 d B, and the average after treatment was 37.0 ± 7.2 d B, the difference was highly significant (P <0.01). Increased hearing by 10 d HLB was effective, 51 ears, the effective rate was 91.1%. Tympanic function curve before treatment of type B 33 ears, C type 18 ears, after treatment, the two types of reduction, there are more As type. Conclusion: This method can improve eustachian tube function and improve hearing in patients with chronic otitis media.
