Overall, VEMP response parameters were found to have fair to good test-retest reliability. The intraclass correlation coefficient value for amplitude was found to be more reliable than latency, with the latency of n23 more reliable than the latency of p13. Clinicians should consider these findings when interpreting VEMP responses. Maintenance of symmetric head rotation with and without EMG monitoring produced reliably reproducible results, the VEMP amplitude being the best criteria.

The cartilage cap occlusion technique of dehiscent superior semicircular canals via a transmastoid and tegmen mini-craniotomy approach is a good option for managing symptomatic patients with a dehiscent superior semicircular canal.
