Objective To analyze CT findings of blunt laryngeal trauma (BLT) and evaluate the value of CT in the diagnosis of BLT. Methods CT diagnosis and treatment of 16 patients with BLT were reviewed. Results Soft tissue injuries were detected in five cases including swelling of the aryepiglottic folds, the false or true vocal cords and airway narrowing in four, and left cricoarytenoid dislocation and card paralysis in one. Supraglottic injuries in two cases including c fractures of the epiglottis in 2 and associated with a laceration of the aryepiglottic folds and the hypopharynx. Glottic injuries in four cases including ventricle fracture of the right thyroid ala in one and midline ventricle or comminute fractures of the thyroid cartilage in three, a square segment of cartilage was depressed into the larynx, and the true vocal cords and the anterior commissure were disrupted in one of this series. Subglottic injuries in five cases including cricoid ring fracture on the opposite side following a lateral force in one, with the fragment depressed into the larynx. Two showed marked comminution of the cricoid ring. Midline vertical fracture of the posterior cricoid plate associated with the laceration of the first tracheal ring in one, and one presented marked disruption of the right cricothyiod joint. Conclusion CT clearly shows the extent of cartilaginous injury and displacement, related soft tissue changes and the degree of resulting airway encroachment, and it may be successfully used to determine the need for open exploration and repair in selected cases of blunt trauma to the larynx.
