Abstract

Objective: To evaluate the effect of CO2 laser stapedotomy and analyze the influence of audiometric
factors on the evolution of tinnitus.
Study design: Retrospective case series.
Setting: Tertiary referral center.
Patients: 151 ears (139 patients, 17 years to 74 years) underwent Laser-assisted stapedotomy for
otosclerosis between May 2009 and October 2018.
Intervention: CO2 laser stapedotomy procedure for otosclerosis.
Results: The incidence of preoperative tinnitus in patients with otosclerosis in our cohort is 51.7%,
with a complete disappearance in 61% of the cases. We haven’t found any statistically significant
results between the resolution of tinnitus after surgery and the hearing result pre and postoperatively
(BC, AC, ABG, SRT, and WRS). On the other hand, we haven’t found any audiometric predictive
factors of the effects of surgery on tinnitus. We have seen a tendency to have more tinnitus regarding
the number of laser shots, but the results aren’t statistically significant.
Conclusion: Stapedotomy may also improve tinnitus in most of the patients with a diagnostic of
otosclerosis. The tinnitus status does not appear to be related to the preoperative or postoperative
audiometric results.
