Summary
Simultaneous bilateral stapes surgery offers satisfactory short-term hearing outcomes with comparable results between ears and no increased complication risk. Further research is needed for long-term validation.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Otosclerosis is a common cause of conductive hearing loss.
- Stapes surgery is a standard treatment for otosclerosis.
- Bilateral otosclerosis necessitates treatment in both ears.
Purpose of the Study:
- To evaluate the preliminary outcomes of simultaneous bilateral stapes surgery.
- To assess hearing improvement and complication risks associated with the procedure.
Main Methods:
- Prospective pilot study of nine patients (8 with otosclerosis, 1 with osteogenesis imperfecta).
- Both ears operated under general anesthesia by the same surgeon.
- Inclusion criteria: conductive hearing loss ≥15 dB (0.5-4.0 kHz), negative Rinne test; exclusion criteria: sensorineural hearing loss >40 dB, other otoneurological conditions.
Main Results:
- Significant reduction in air-bone gap: first ear from 28 dB to 10 dB, second ear from 24 dB to 8 dB.
- Four patients reported mild, temporary dizziness, which resolved completely.
- No significant sensorineural hearing loss occurred postoperatively.
Conclusions:
- Simultaneous bilateral stapes surgery demonstrates satisfactory short-term results.
- Hearing outcomes were comparable between the operated ears.
- The procedure appears safe with no increased complication risk for the second ear, though larger studies and longer follow-up are recommended.
