Abstract
Background: Conductive hearing loss is one of the com-monest diseases that result from a multitude of causes. VEMP is one of the tools used to test the vestibular system. Sound elicited VEMP require an intact conductive system. To over-come the conductive element, stimulation could be performed by bone conduction.
Aim: This study tries to clarify the effect of bone conduc-tion stimulation on VEMP response.
Method: Twenty patients with chronic suppurative otitis media and conductive hearing loss were examined as well as 10 healthy individuals as a control group. All of them had pure tone audiometry for air conduction and bone conduction as well as VEMP by air conduction and bone conduction.
Results: It was found that 75% had VEMP to bone con-duction stimulation while 25% had VEMP to air conduction stimulation.
Conclusion: VEMP can be used to test the presence of a conductive hearing loss as bone conduction VEMP can be elicited with higher degree of accuracy.
