Diagnosis and primary management of laryngeal trauma.

Four cases of laryngeal trauma are presented and the literature is reviewed. Diagnostic techniques and controversial primary treatment of airway obstruction are discussed. Recommendations include the use of indirect laryngoscopy on initial examination and the performance of a tracheostomy in cases of airway obstruction, in lieu of endotracheal intubation. The cases illustrate these points and demonstrate the variability in time intervals between injury and onset of symptoms.
