Malignant hyperthermia is a seemingly rare genetic myopathy. Hypermetabolic crisis accompanied by a rise in body temperature to as high as 44 degrees C is its hallmark. Malignant hyperthermia is usually triggered by potent inhalational anesthetics and/or depolarizing muscle relaxants. ⋯ The contracture study was positive in six of the seven patients studied. No anesthetic or surgical complications were encountered. This study demonstrates that patients at risk of developing malignant hyperthermia crisis can have otologic surgical procedures performed safely while undergoing appropriately selected general anesthesia.
