Head and Neck ImagingTrauma, laryngeal
Adequate treatment of laryngeal
trauma is necessary to avoid
stenosis or aspiration, and to restore an acceptable voice quality. Delay in the treatment may lead to a less good result. Mucosal tears, false passages and tracheal rupture can be identified by laryngoscopy, but extensive soft tissue swelling and injury may limit its diagnostic yield.
CT has proven its value in the evaluation of the traumatized larynx, showing fractures of the laryngeal skeleton and their displacement (
Fig.1), and outlining soft tissue
haematoma and disruption (
Fig.2). Surgery can be avoided when
CT depicts nondisplaced fractures or normal laryngeal cartilages in the presence of soft tissue
haematoma.
