Popis: Purpose To compare hearing results and complication rates between two groups of patients operated on by endoscopic stapes surgery (ESS) for otosclerosis, either with CO2 fiber laser or microdrill. Methods A case–control study was performed. All consecutive cases of CO2 fiber laser ESS operated at a single center during the period 2017–2020 (case group) were matched to a control group of patients operated by traditional technique, according to year of surgery, preoperative mean air–bone gap, sex and age. Audiological data from preoperative and postoperative examinations and complication rates were compared. Results 46 cases were included. Mean operative time was significantly longer in the laser cohort (65 min) than in the drill one (45 min) (p = 0.003). Similar results were found in the two groups regarding the mean postoperative BC-PTA. The high-frequency bone conduction resulted significantly higher in the laser group (p = 0.002), suggesting an overclosure effect in the laser group. Consistently, a significant improvement of the BC-PTA threshold at 2000 Hz postoperatively was found in the laser group (p = 0.034). The postoperative AC-PTA significantly improved in both groups at all frequencies (p Conclusion This study is the first to compare hearing results and complications between CO2 fiber laser and microdrill in ESS. Our results demonstrated similar functional outcomes between the two groups, confirming ESS as safe and effective, regardless of the technique used.
