Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The regular opening of the eustachian tube plays an important role in maintaining normal pressure in middle ear cavity, hearing function and preventing the occurrence of middle ear inflammation. The current evaluation of Eustachian tube function mainly depends on the patient's history of auricular distention, occlusion, physical examination (Valsalva), acoustic impedance test. However, these tests can not accurately assess the eustachian tube function, the lack of quantitative analysis of eustachian tube function. Currently, surgical treatment of patients with chronic otitis media is one of the most important treatment methods. However, the current results show that some patients can not reconstruct the gas-containing structure of the middle ear after operation, which brings about the treatment of diseases and the recovery of auditory function Difficulties. Although domestic and foreign scholars believe that eustachian tube function in tympanoplasty in the reconstruction of the middle ear with air cavity plays an important role, but due to the lack of a reliable quantitative evaluation of eustachian tube function, eustachian tube function in the occurrence of chronic otitis media , There is a lack of reliable evidence-based medicine in the assessment of the value of development and prognosis. In recent years, a new eustachian tube function evaluation method - Eustachian tube manometry technique, began a quantitative objective assessment of Eustachian tube function, combined with physical examination and subjective symptom scales to conduct a comprehensive assessment of eustachian tube function . This study wants to evaluate the eustachian tube function preoperatively and postoperatively in patients with chronic otitis media who underwent surgery. Regular postoperative follow-ups were used to understand the importance of eustachian tube function in the prognosis of chronic otitis media surgery , In order to further improve the eustachian tube function and improve the surgical curative effect of chronic otitis media.
