• Clinical stapedius reflex determinations presently include only threshold and decay measurements. Recent observations indicate that reflex latency, amplitude, and rise and relaxation times are sensitive to cochlear and brain stem disorders. Our investigations using a chronic animal model of an experimental acoustic tumor show that reflex amplitude, latency, and rise time are exquisitely sensitive to extrinsic pressure on the auditory nerve. Because of our observations and those of others, we suggest that further quantification of the reflex test will increase its sensitivity and reliability. Quantification can be achieved by an interface between an impedance bridge and a small computer to provide on-line averaged values for each reflex parameter.
