Shell-shock blindness, mutism, deafness: Blindness spontaneously vanished, 24 hours. Mutism, 2-3 months. Deafness cured by “small operation.”
Case 514. (Hurst, September, 1917.)
A lance corporal, 26, became blind, deaf and dumb, though without losing consciousness, when blown up by a shell, August 29, 1916. His sight returned next day. On reaching England he talked in his sleep. Encouragement, electricity, etherization failed to effect improvement. One night in November he woke up and asked the sister for a drink; thereafter he talked normally.
Seven months after the shell explosion he was transferred to the neurological section at Netley, March 21, 1917. Deaf to air and bone conduction, a loud noise behind him caused a slight tremor of hands, with blinking and dilatation of pupils; but further stimuli of the same sort failed to produce such reactions. Normal nystagmus and giddiness on functional tests of vestibular nerve and canals. The internal ear was then probably free from organic changes. Since shell-shock mutism is always hysterical, it was probable that the deafness was hysterical. Under hypnosis (staring at lines for fifteen seconds) he showed no change. During natural sleep, also, a shout of “Fire” and metallic noises failed to wake the patient or to produce contraction of eyelids. Electric suggestion (despite the patient’s belief in electricity) and reëducation failed.
April 16, he was told that a small operation would have to be done April 20. To this he readily consented. Two small incisions were made behind the ear under light ether and suture was inserted. A loud noise was made during the “operation”; he heard this noise and jumped from the table. To his intense delight normal hearing returned in a few minutes. Next day hearing was tested and found normal to air and bone conduction. He was discharged to duty three weeks later and on his way to France, June 29, demonstrated his normal hearing to the physicians.
