[Analysis of therapeutic effect of tympanoplasty type Ⅰ in elderly patients with chronic suppurative otitis media].

To summarize the clinical characteristics of elderly patients with chronic suppurative otitis media who underwent type Ⅰ tympanoplasty, and to analyze for the first time the efficacy of type Ⅰtympanoplasty in elderly patients from multiple perspectives of medical data and patient evaluation, so as to provide reference for doctors and patients to make rational decisions on treatment methods. Forty-four elderly patients（45 ears） who underwent type Ⅰtympanoplasty from May 2016 to February 2022 were retrospectively analyzed, and were followed up for 6 months to 3 years. To analyze the clinical characteristics of patients, summarize the success rate of graft, and compare the hearing level of patients before and after surgery. The patients' quality of life before and after operation was evaluated by Chronic Ear Survey, and the scores obtained were statistically analyzed. Of the 44 patients（45 ears）, 22.22%（10/45） of the ears had predisposing factors. The percentage of hearing loss, ear pus and tinnitus were 91.11%（41/45）, 88.89%（40/45） and 42.22%（19/45）, respectively. Mixed deafness accounted for 55.56%（25/45）. 66.67%（30/45） patients were diagnosed as tympanosclerosis by operation. The graft success rate was 97.78%. There was no significant difference in bone conduction hearing threshold before and after surgery, but there was significant difference in air conduction hearing threshold and air bone conduction difference. The scores of "activity restriction", "symptom", "medical resource utilization" and their total scores of the preoperative and postoperative were statistically different. Hypertension or diabetes had no significant effect on the efficacy of type Ⅰ tympanoplasty in elderly patients. Type Ⅰtympanoplasty is safe and effective in elderly patients, and the quality of life of patients after surgery is significantly improved. It is necessary to increase the awareness of elderly patients to seek medical advice and use surgical methods reasonably to treat chronic suppurative otitis media.
