Clinically, discrepancies between behavior hearing thresholds and objective electrophysiologic examinations, such as impedance audiometry, otoacoustic emissions (OAE), and auditory brainstem response (ABR), will raise the suspicion of this disorder. It is judged to be due to psychological factors and that patients do not intentionally produce the symptom. Conversion deafness is sometimes reported in children but is extremely rare among adults. Two young adults with this disease are presented. These 2 patients were both under enormous stress from the national entrance examinations for universities. Pure tone audiometry showed bilateral hearing deterioration, but OAE and ABR were normal. The hearing of both patients recovered after treatment. The diagnosis, prognosis and treatment of this disorder are also discussed. It is important to discover the psychological stress in patients with conversion deafness. This report aims to increase awareness of this condition and avoid unnecessary steroid use in its treatment. © 2006 by Lippincott Williams & Wilkins, Inc.
