Palinacousis.
Palinacousis is derived from the Greek words palin, which means again or anew, and acousis, meaning hearing. It was first described by Jacobs et al. (1971), who defined the phenomenon as "an auditory illusion of perseveration or persistence of sound impressions for seconds, minutes, or hours after the cessation of auditory stimulation." The auditory perseveration does not occur spontaneously but is triggered by something in the environment. A limited number of cases have been described in the literature. This chapter describes the anatomic abnormalities that may cause this phenomenon, the clinical characteristics that define palinacousis, differential diagnosis and potential etiologies.
