Objective
To evaluate the efficacy and safety of awake stapedectomy under hypnoanalgesia (HA) compared to general anesthesia (GA) and local anesthesia (LA) in patients with otosclerosis.
Methods
A single-center retrospective study included 131 adult patients (mean age: 49 years; 78% female) who underwent laser stapedectomy between 2020 and 2022: 58 GA, 23 LA, 50 HA. Primary outcome measures comprised operative room occupancy time, anesthetic consumption, and postoperative audiometric results.
Results
HA significantly reduced operative room occupancy time (73.5 ± 18.6 min vs 103.7 ± 24.6 min in GA, P < 0.001; vs 81.8 ± 20.5 min in LA, P = 0.092), stapedectomy duration (39.9 ± 12.4 min vs 48.9 ± 21.5 min in GA, P = 0.0252; vs 38.9 ± 13.2 min in LA, P = 0.4601), preoperative time (30.2 ± 9.5 min vs 45.7 ± 9.5 min in GA, P < 0.001; vs 38.6 ± 12.2 min in LA, P = 0.0022), and recovery room time (26 ± 15.1 min vs 67.5 ± 20.7 min in GA, P < 0.001; vs 47.4 ± 20.7 min in LA, P < 0.001). HA also significantly reduced remifentanil consumption (169.8 ± 101.6 μg vs 848.6 ± 308.8 μg in GA, P < 0.001; vs 323.9 ± 94.4 μg in LA, P < 0.001). Postoperative audiometric outcomes showed no significant differences between groups.
Conclusion
Hypnoanalgesia for awake stapedectomy provided significantly greater efficacy compared to general anesthesia, reducing operative time and anesthetic consumption, with comparable audiometric outcomes.
