Some patients, who have been treated repeatedly for otitis media for many years but have not recovered, or even those whose ears are still flowing after surgery, should not lose their confidence in treatment, as chronic otitis media is now much better treated than before. Chronic otitis media is a common clinical disease, but due to the lack of knowledge of this disease in the past and the limited treatment means, the efficacy has been poor for a long time, so that some patients have lost their confidence in treatment after a long journey of seeking medical help! Now, with the improvement of medical standards, the treatment of otitis media has undergone significant changes in the past 10 years: 1. The use of high-resolution CT has led to a tremendous improvement in clinicians’ diagnosis and understanding of chronic otitis media; 2. The use and popularity of microscopes have made fine otologic surgery possible; 3. The use of electric drills has made otologic surgery more detailed and able to clean out more lesions; 4. 5. The use of artificial hearing bone materials has made hearing improvement more convenient and efficient. At the same time, theories related to otitis media continue to develop, and new breakthroughs have been made in the following areas, bringing benefits to patients: 1. The function of the eustachian tube is no longer a contraindication to surgery for otitis media; 2. Surgery can be performed with or without pus in the middle ear; 3. The theory of ventilation and drainage in the middle ear has further deepened our understanding of otitis media, and a number of new surgical and therapeutic modalities are progressing. The current view is that most chronic otitis media require surgical treatment, and that surgical treatment is very effective. At our institution, the vast majority of patients with chronic otitis media can obtain dry ears and improved hearing with reasonable treatment. The approximate rates are 90% for dry ear and 60-70% for hearing improvement after surgery. For patients who do not improve their hearing with dry ear, they can also get good results with hearing aids.
