Additional treatment options

Audiological Surveillance Program

Regular hearing evaluations with audiological monitoring to track hearing thresholds, identify fluctuations, and adjust intervention strategies accordingly.

monitoring

Endolymphatic Sac Surgery

Surgical intervention targeting the endolymphatic sac in cases of associated vestibular dysfunction or progressive hearing loss, with the goal of reducing inner ear pressure.
