Abstract:
Background: This paper evaluates endoscopic stapedotomy from the perspectives of a group of 3 surgeons, each of whose experience in endoscopic and microscopic stapedotomy is 3 years and more than 12 years, respectively.Methods: Thirty-four patients clinically diagnosed with stapedial otosclerosis were alternately assigned for unilateral, microscope- and endoscope-assisted stapedotomy following the selection criteria given. Results were evaluated with predetermined epidemiologic, preoperative, perioperative, and postoperative outcome parameters.Results: The microscope group had 12 ears with otosclerosis and the endoscope-assisted group 14. Ears found to have conditions other than otosclerosis at surgery, and patients lost to follow-up were excluded. Apart from the operative time, the difference in the results of none of the parameters was statistically significant in the two groups. The average operative times for microscope- and endoscope-assisted stapedotomy were 63 minutes and 86.5 minutes, respectively, the difference being statistically significant (P < .001).Conclusions: From the perspectives of otologists in differential positions in the learning curve for microscope- and endoscope-assisted stapedotomy, there were no statistically significant differences between the two procedures in the execution of the steps to achieve "adequate surgical exposure" and in postoperative outcomes, except for operative time.
