Management of subglottic foreign bodies.

Foreign body aspiration is not an infrequent encounter in the practice of otolaryngology and requires immediate attention. The vast majority of foreign body aspirations occur in children less than 3 years of age, and the actual event of aspiration is frequently not witnessed. Although inhaled foreign bodies most often lodge in the bronchi, laryngotracheal foreign bodies also occur and are potentially more dangerous. Specifically, subglottic foreign bodies present unique clinical challenges. The diagnosis of subglottic foreign bodies is often difficult and they are commonly confused with other causes of upper airway obstruction. We present our experience with the diagnosis and management of seven patients with subglottic foreign bodies, who presented with an abnormal airway and whose problems were initially misdiagnosed. The radiographic and clinical features are discussed with a review of our surgical management.
