title: Recovery of crossed acoustic reflexes in brain stem auditory disorder.
abstract: Crossed acoustic reflexes were serially monitored in a patient receiving radiotherapy for an intra-axial brain stem tumor. Analysis revealed a pattern of systematic recovery as the brain stem lesion responded to therapy. Crossed reflexes were observed at more and more test frequencies, until responses were present on both ears for all test signals. Pure-tone sensitivity and speech intelligibility remained within the normal range throughout the observation period.
