Question
I understand that middle ear pathologies may negate a VEMP response. However, will hyper-compliant tympanic membranes also negate a VEMP response?
Answer
The reason air-conduction VEMP responses are diminished in patients with middle ear pathologies is that the sound intensity delivered to the labyrinth is reduced in these patients. Because the sound transmission is not affected by hyper-compliant tympanic membranes, VEMP responses should not be affected. Incidentally, bone-conduction VEMPs that bypass the middle ear can be used in patients with middle ear pathologies.
