Objectives Learn about possible differences of results by 4 different stapes prostheses. Methods In this retrospective study, all 126 contiguous patients undergoing stapes surgery for otosclerosis are included. All surgeries were performed by 2 surgeons. 4 different types of stapes prostheses were used in separate time intervals. Starting with teflon-platinum wire prosthesis, to gold piston, to titanium piston, to the self-retaining titanium Clip-piston. Results Pre- and postoperative pure tone and speech audiograms are compared. The best results were achieved by the Clip-Piston. Improvement in PTA over other pistons was 4 dB with p= 0,027 (Mann-Whitney). Bone conduction levels were better by 2 dB. In speech audiometry intellegibility was better by 3 dB with p=0,024 (Mann-Whitney). Conclusions The tight self-fixation of the Clip-Piston to the long process of the incus achieved the best results in pure tone and even more so in speech audiometry. The reason might be due to reduced slippage of the stapes prosthesis at the attachment to the incus. As other studies have shown, tight fixation of a stapes prosthesis provides the best results. The Clip-Piston achieves this by its spring action and without the danger of heat and strangulation as by other stapes pistons.

Objective To systematically review the current literature regarding the operative outcomes of stapes surgery for stapes fixation via the endoscopic and microscopic approaches. Data Sources PubMed, Embase, and Web of Science. Review Methods An electronic search was conducted with the keywords “endoscop* or microscop*” and “stapes surgery or stapedectomy or stapedotomy or otosclerosis or stapes fixation.” Studies were included if they compared endoscopy with microscopy for stapes surgery performed for stapes fixation and evaluated hearing outcomes and postoperative complications. Articles focusing on stapes surgery other than for stapes fixation were excluded. Results The database search yielded 1317 studies; 12 remained after dual-investigator screening for quantitative analysis. The mean MINORS score was 18 of 24, indicating a low risk of bias. A meta-analysis demonstrated no statistically significant difference between the groups with regard to operative time, chorda tympani nerve manipulation or sacrifice, or postoperative vertigo. There was a 2.6-dB mean improvement in the change in air-bone gap in favor of endoscopic stapes surgery and a 15.2% increased incidence in postoperative dysgeusia in the microscopic group, but the studies are heterogeneous. Conclusions Endoscopic stapes surgery appears to be a reasonable alternative to microscopic stapes surgery, with similar operative times, complications, and hearing outcomes. Superior visibility with the endoscope was consistently reported in all the studies. Future studies should have standardized methods of reporting visibility, hearing outcomes, and postoperative complications to truly establish if endoscopic stapes surgery is equivalent or superior to microscopic stapes surgery.
