Auditory neuropathy spectrum disorder (ANSD) is a spectrum of conditions marked by diminished auditory function and believed to be caused by the impaired neural transmission of auditory stimulation in the setting of functional outer hair cells (Rance1). There are reports of "spontaneously resolving" or "transient" ANSD (TAN) in the literature. In this case report of TAN, we demonstrate the resurgence of the ABR waveform morphology over a 3-year period to reveal electrophysiologic testing consistent with the subject's functional hearing level by age 3 years.
