Comparison of Bone Cement Fixation for Stapes Prostheses with Different Materials in Endoscopic Primary Stapedectomy

Otosclerosis is a complex skeletal condition that originates from both hereditary and environmental factors. Gradual conductive hearing loss is the main character. Aim to contrast and assess the postoperative results, such as hearing improvement, following the use of bone cement to fix the Titanium versus Teflon stapes piston. 50 patients who had endoscopic stapedotomy with different prostheses insertions were included in this prospective, randomized research. They were splitted into two groups in the: group A consisted of 25 ears in which titanium prostheses with bone cement were applied, while group B consisted of 25 ears Teflon prostheses with bone cement were used. A statistically significant difference was observed in average air conduction (better hearing) between groups A and B at 3, 6, and 12 months postoperatively based on audiometric results. When comparing groups B and A after 3, 6, and 12 months after surgery, the average air bone gap (ABG) was greater in group B, and this difference was statistically significant. Between the two groups, there was no discernible variation in any of the preoperative metrics. 96% of groups A and B were successful. Using bone cement in primary stapedotomy may help fix the procedure and reduce the chance of persistent hearing loss in patients with otosclerosis. This is especially true when titanium is used, as titanium has the ideal mass and stiffness to support acoustic transmission with a low rate of adverse effects and better average ABG.
