AbstractThirty patients with external laryngeal trauma were analysed retrospectively. Injuries were mostly caused by motor vehicle accidents (car = 36.7 per cent; motorcycle = 23.3 per cent). The main presenting symptoms and signs were hoarseness, neck tenderness, dysphagia, and neck emphysema. Sites of laryngeal injury included arytenoid swelling, vocal fold injury, soft tissue contusion or superficial mucosal laceration, cricoarytenoid dislocation, thyroid fracture, epiglottic fracture and mixed injuries. Treatment was varied depending on the severity of the injuries. Sixteen cases were managed conservatively by medical treatment; two cases received intubation; four cases were treated initially by tracheostomy; eight cases received surgical repair and/or reconstruction; cases made a full recovery of the voice and 18 cases fair voice recovery due to either sustained vocal fold swelling or limitation of vocal fold movement. One case was graded as poor. Twenty-eight cases had good airway patency and two cases fair airway patency. A delay in the early detection of laryngeal trauma may precipitate into life-threatening airway problems, therefore prompt and accurate diagnosis should be followed immediately by skillful airway management.
