No sense; no sensibility--a tale of two adult hairdrier burns.

Hot air burns resulting from hairdriers held against the skin are rare. The largest published clinical series relates to burns in children injured by the use of hairdriers at home. Adults are assumed not to be at risk because the pain associated with thermal injury would normally stimulate acute action to prevent further skin damage. We present two adult patients in whom the normal protective mechanisms were inactive. There was loss of consciousness resulting from an epileptic fit in one case, and the local absence of sensation in a flap used to reconstruct a breast after mastectomy, in the other. The temperatures generated by hairdriers were experimentally assessed and the results are reviewed. We emphasize that hairdriers are a potentially dangerous source of hot air and can cause burns.
