Abstract
- Objectives: Evoked tympanic membrane displacement (TMD) measurements, quantified by Vm, record small volume changes in the ear canal following stimulation of the acoustic reflex. Vm shows a correlation with intracranial pressure (ICP) and has been proposed as an option to non-invasively measure ICP. The spontaneous pulsing of the tympanic membrane, driven by the cardiovascular pulse, may contaminate the recordings and contribute to high measurement variability in some subjects. This study hypothesised that the larger the spontaneous vascular pulse, the larger the variability in Vm.
