Objectives: We recorded and compared the vestibular evoked myogenic potentials (VEMPs) before use of an endolymphatic mastoid shunt (EMS) and 1, 12, and 48 months after placement of the shunt.
Methods: Air-conducted VEMPs were recorded in 28 patients affected by intractable Meniere's disease and treated with placement of an EMS.
Results: One month and 12 months after the surgery, VEMPs were not detectable in the operated ear in 100% and 86% of the patients, respectively. Forty-eight months after the surgery, they were elicited in 79% of the patients.
Conclusions: We conclude that VEMPs are a clinically useful tool in the postoperative follow-up of patients with an EMS.
