文摘

In this study, the association between the middle ear mucosal condition and post-tympanoplasty audiologic outcome was investigated in patients with chronic otitis media without cholesteatoma. One hundred and forty-three patients with chronic otitis media were collected in the Department of Otorhinolaryngology-Head and Neck Surgery at Asan Medical Center between January, 2009 and December, 2011. In the course of tympanoplasty, the status of the middle ear mucosa was divided into normal or abnormal by one surgeon. Pure tone audiometry was performed preoperatively and postoperatively, and post-tympanoplasty tympanogram was also conducted to estimate the condition of middle ear cavity. Of the 143 patients, there were 73 patients with normal middle ear mucosa and 70 patients with abnormal middle ear mucosa around Eustachian tube opening. The mean ABG of subjects with normal middle ear mucosa was 20.1 dB preoperatively, and 9.7 dB postoperatively (p < 0.001). Preoperative mean ABG was 22.4 dB and postoperative mean ABG was 16.4 dB in abnormal middle ear mucosa group (p = 0.137). Postoperative ABGs for 500 and 1000 Hz (7.1, 7.7 dB) in normal middle ear mucosa patients were significantly lower than those (17.2, 19.4 dB) in abnormal middle ear mucosa patients (p < 0.001). There was statistically significant correlation between middle ear mucosa status and post-tympanoplasty audiologic outcomes. The better condition of middle ear ventilation, the better postoperative hearing thresholds revealed after tympanoplasty.
