OBJECTIVE: Aim: To compare the severity of early postoperative vestibular disorders after stapedotomy using two techniques of stapes footplate fenestration: the Skeeter microdrill and the manual perforator.
PATIENTS AND METHODS: Materials and Methods: Sixty patients with otosclerosis who underwent stapedotomy in 2024-2025 were included in the study. The patients were randomly divided into two equal groups: Group A-stapedotomy performed using a Skeeter microdrill; Group B-stapedotomy performed using a manual perforator. Audiological assessment included pure-tone audiometry (air conduction, bone conduction, air-bone gap) and speech perception tests. Vestibular function was evaluated preoperatively and on postoperative day 7 using electronystagmography, as well as positional and static-coordination tests. An integrated clinicalinstrumental vestibular scale (0-3 points), combining clinical symptoms, Romberg and Fukuda tests, and objective ENG parameters, was applied.
RESULTS: Results: Spontaneous nystagmus on postoperative day 7 was detected in 26.7% of patients in Group A and in 40% of patients in Group B (p=0.59). The mean postoperative increase in the vestibular score was significantly lower in Group A (0.73 vs 1.23; p=0.02). Both groups demonstrated significant improvement in air-conduction thresholds and reduction of the air-bone gap, with no statistically significant intergroup differences in audiological outcomes.
CONCLUSION: Conclusions: Both stapedotomy techniques effectively restore hearing in patients with otosclerosis. However, stapedotomy performed with a Skeeter microdrill is associated with less pronounced early postoperative vestibular disturbances compared with the manual perforator. The proposed integrated vestibular scale enables objective assessment of vestibular dysfunction in the early postoperative period and is suitable for routine clinical practice.
