Non-organic hearing loss in United Kingdom military personnel.

Non-organic hearing loss (NOHL) is a condition in which there is audiometric discrepancy between the real hearing threshold and the measured threshold of the patient, in the absence of any organic disease. It can, rarely, be the manifestation of a somatoform disorder when it is known as conversion deafness. We present a case of conversion deafness diagnosed following a five-year period of apparent fluctuating unilateral hearing loss, and discuss the diagnosis, clinical and occupational considerations of managing this condition in a military environment.
