  • Title: [Response latency characteristics for ENT medical assessment of auditory brain stem evoked response].
    Author: Janssen T, Steinhoff HJ, Böhnke F.
    Journal: HNO; 1988 Aug; 36(8):318-23. PubMed ID: 3049476.
    Abstract:
    A schematic description of the correlation between the various types of hearing disorders and the behaviour of auditory brain stem responses (ABR) is presented. Conductive pathology and high-frequency cochlear hearing loss prolong wave component latency due to energy loss and hair cell dysfunction. Latency is not affected in flat cochlear hearing loss. Prolonged interwave latencies between wave I and wave V indicate eighth nerve and brain stem disorders. An algorithm in the form of a flow chart was developed for location of the malfunction. Families of characteristics of wave V intensity-latency functions were designed for faster detection and more precise evaluation of conductive and cochlear hearing losses.
