Evaluation of the auditory system: an update.
The purpose of this paper is to describe the audiologic techniques currently used at the Otologic Medical Group, Inc. Auditory threshold in children is determined by a combination of behavioral and objective audiometric techniques. When behavioral techniques fail, auditory brainstem response audiometry combined with impedance audiometry gives a good estimate of hearing thresholds. Impedance audiometry is a valuable addition to the diagnosis of cochlear otosclerosis. This technique is also of benefit in the neurotologic evaluation. Auditory brainstem response audiometry is the most accurate method of detecting an acoustic tumor. We no longer use SISI, tone decay, or Bekesy tests. The newer audiometric studies have greatly improved our evaluation of the auditory system.
