Exploding microwaved eggs—revisited

Different types of injuries are described as caused by the use of microwave ovens. Four of 41 burns from microwave ovens, presented by an international survey in 1986, were due to exploding microwave-heated eggs. Careful review of the English language literature through a Medline search from 1966 to 2000 was performed, in search of burns caused by exploding eggs. Clinical information from the published articles was reviewed and missing information was completed by e-mail correspondence with authors. Our own case was added to the collected data, and a total of 13 cases were analyzed. The average age of patients was 24.3 years (range, 7–49 years). All patients suffered from superficial burns of the mid and upper face, namely the forehead, periorbital region, dorsum of nose and malar areas. All patients with information available complained of ocular disturbances, and three suffered long-term decrease in visual acuity. Long-term skin complications were not reported. In summary, the clinical presentation of a facial injury from an exploding microwave-heated egg is relatively constant and mild. Favorable outcome can be expected but a meticulous ophthalmologic evaluation and a close follow-up are mandatory for prevention of long-term sequelae.
