Abstract Purpose To report the predictability of ossicular chain (OC) fixation on preoperative temporal bone computed tomography (TBCT) in chronic otitis media (COM) with tympanosclerosis (TS). Methods Fifty-six patients who had surgery for COM in our ear, nose and throat clinic between 2015 and 2017 were included in this retrospective case–control study. The patients were equally divided into two groups as those with TS and without TS. The complaint of preoperative otorrhea, values of incudostapedial joint (ISJ) angulation on preoperative TBCT scans, postoperative long-term hearing results, and postoperative complications were compared between the two groups. Results There was a statistically significant difference between the ISJ angulations of the operated and healthy sides in the COM group with TS (102.27 ± 7.92 and 91.90 ± 5.59 degrees, respectively, p 0.05). In addition, when the ISJ angulations of the operated sides of the two groups were compared, it was statistically significantly higher for the TS group compared to the non-TS group (102.27 ± 7.92 and 95.04 ± 4.86 degrees, respectively, p
