Hypothesis
The study aims to explore the relationship between preoperative imaging and intraoperative findings of semicircular canal obstruction and to develop surgical strategies for dealing with these obstructions.
Conclusion
Preoperative imaging can indicate locations of obstructions in the semicircular canals, and various surgical procedures can be applied to enable appropriate electrode positioning.
Supporting Evidence
- Preoperative imaging suggested obstructions by soft tissue in the semicircular canals.
- Different surgical procedures were employed to facilitate proper electrode insertion.
- All patients had successful electrode implantation in the semicircular canal ampullae.
Takeaway
Doctors can use special pictures of the inner ear to find blockages before surgery, and they have different ways to fix these blockages so they can put in a device that helps with balance.
Methodology
Patients undergoing vestibulocochlear implantation were included based on preoperative imaging indicating obstruction in the semicircular canal, and various surgical strategies were developed and evaluated.
Limitations
The study only included a small number of patients, and those with obstructions in the ampullary end of the canal were excluded.
Participant Demographics
Three patients with bilateral vestibulopathy and hearing loss due to DFNA9.
