EXTENSIVE studies of the blood supply to the ear have been made and are contained in standard texts of anatomy. Histological studies of the microvascular system of the chochlea have been reviewed,1 but I can find no reference to physiological studies of the recordable arterial pulse from the external auditory canal except those reported by me.2
Studies of the vascular system of the ear and the recordable arterial pulse present many difficulties because of the inaccessibility of the internal structures of this organ.
This report is presented in the hope that readers may have suggestions on the origin of the two types of recordable arterial pulses, the mechanism by which the eardrum functions in the presence of these pulses, the physiological and pathological significance of these pulses, and to illustrate refinements of technique for making these studies.
