Many inner ear disorders may be caused by alterations in cochlear blood flow (CBF). However, each measurement technique used to monitor CBF has limitations in examining the relationship between otopathologic states and blood flow. This study investigates laser Doppler flowmetry (LDF) and its fundamental drawback: the unknown relationship of LDF output to(More)
In a companion paper, we reported that electrical stimulation increased cochlear blood flow (CBF). This response was found to be an increasing function of current intensity and was frequency-selective, with the best response at approximately 500 Hz continuous sinusoidal current. The present investigation seeks to discover the mechanism of this effect.(More)
Whereas the anatomy of the vasculature supplying the intratemporal facial nerve is well known, little is known of the dynamics of blood flow within the nerve. The present study was performed to ascertain whether laser Doppler flowmetry (LDF) could detect changes in blood flow within the tympanic segment of the rabbit facial nerve. Compression of the facial(More)
