Abstract

This chapter discusses laryngotracheal trauma, where the commonest cause of laryngotracheal trauma is due to road traffic accidents, which cause high velocity blunt injuries. Bullet and knife wounds cause penetrating injuries. Other causes of laryngotracheal trauma are such as burns and scalds, intubation injuries or following radiotherapy reactions. Haemorrhage and oedema of supraglottic or subglottic region will be present. Subcutaneous emphysema due to tears in laryngeal mucosa may be seen. Besides disruption of cricoid cartilage and trachea from each other, there may be injuries to tracheal rings also. Symptoms of laryngotracheal trauma include respiratory distress, hoarseness of voice, dysphagia, pain in the neck and haemoptysis. High-velocity blunt injuries will fracture the skeleton of the larynx. Mirror examination may show the mucosal tears, oedematous arytenoids and dislocated or subluxated arytenoids and vocal cords. Direct laryngoscopy should be done in all cases. In case of disruption of larynx and trachea end-to-end anastomosis is indicated.
