Acute angioedema during maxillomandibular fixation: a possible life-threatening situation

Anaphylaxis due to head injury

Both anaphylaxis and head injury are often seen in the emergency department, but they are rarely seen in combination. We present a case of a 30-year-old woman who presented with anaphylaxis with urticaria and angioedema following a minor head injury. The patient responded well to intramuscular epinephrine without further complications or airway compromise. Prior case reports have reported angioedema from hereditary angioedema during dental procedures and maxillofacial surgery, but there have not been any cases of first-time angioedema or anaphylaxis due to head injury.

Hereditary angioedema: report of case

Hereditary angioedema (HAE) is a life-threatening disorder triggered by trauma or stress, which causes various organ systems to become edematous. Most mortality is observed secondary to laryngeal edema, caused by dental manipulation. This disorder requires special medical management before dental treatment. Some drugs also exacerbate the disorder. Current methods of treating patients with HAE are presented.
