Laryngeal foreign body causing bronchial spasm.

Foreign bodies (FB) in the larynx and trachea usually lead to alarming circumstances, with death by complete obstruction of the respiratory tract as its utter consequence. Incidence rates are not high (2-11% of respiratory tract foreign bodies). Children from 6 months to 4 years of age are the most frequently affected, as expected due to their yet immature swallowing neuromuscular mechanism and the oral stage. In general terms, inhaling FB produces intense coughing and suffocation, and possibly cyanosis, asphyxia, sweating, vomiting, and dysphonia. Larynx papillomatosis must be ruled out as it may present similar findings .
