Supraglottitis: An airway emergency

Abstract

Supraglottitis is a life-threatening condition and refers to inflammation of the epiglottis and the surrounding supraglottic structures. Children usually present with only a swollen epiglottis, termed epiglottitis. Fortunately, the incidence of epiglottitis in children has declined following routine Haemophilus influenzae type B vaccination, but the incidence in adults has increased. Supraglottitis has a high morbidity and mortality from the associated risk of airway obstruction. Therefore, early recognition and urgent secondary care referral is paramount. However, the presentation of this condition can be subtle and differs between children and adults; this can lead to difficulties in diagnosis. This article will review the clinical presentation and management of supraglottitis, an important differential for acute sore throat and hoarse voice.
