We aimed to investigate the effect of stapes fixation on hearing results in patients who underwent mobilization surgery due to tympanosclerosis (TS). Seventy-nine patients were retrospectively analyzed and divided into two groups. Forty-four (55.7 %) patients with mobile stapes were classified as group 1, and 35 (44.3 %) patients with fixed stapes were classified as group 2. Improvement of the air-bone gap (ABG) to become less than 20 dB and the pure-tone average (PTA) by at least 10 dB postoperatively were accepted as success criteria. The PTA and ABG levels were significantly improved in both groups. The pre- and post-operative PTAs were 46.57 +/- A 15.55 and 25.84 +/- A 15.47 dB, respectively, in group 1 (p = 0.001). The pre- and post-operative PTAs were 55.64 +/- A 12.69 and 36.20 +/- A 14.47 dB, respectively, in group 2 (p = 0.001). The pre- and post-operative ABG levels were 35.36 +/- A 10.53 and 16.91 +/- A 8.54 dB, respectively, in group 1 (p = 0.001). The pre- and post-operative ABG levels were 41.68 +/- A 8.78 and 22.20 +/- A 10.03 dB, respectively, in group 2 (p = 0.001). A gain a parts per thousand yen10-dB in the PTA in groups 1 and 2 was found in 34 (77.2 %) and 23 (65.7 %) patients, respectively, and the difference between the groups was not significant (p = 0.684). The post-operative AGB in groups 1 and 2 was less than 20 dB in 32 (72.7 %) and 21 (60 %) patients, respectively, and the difference between the groups was not significant (p = 0.733). No significant negative effect of stapes fixation on post-operative hearing results in TS was detected. Successful results can be obtained with a mobilization procedure, even if the stapes is fixed.
