Abstract:
Injuries to the larynx may have extracorporeal (external), or endolaryngeal (internal), causes and are here classified on the basis of traumatic mechanisms. External trauma may be due to the action of blunt force or sharp objects--also including ruptures. Internal injuries may occur as a result of endotracheal intubation (also for anesthesia), long-term intubation and mechanical ventilation, ingestion of foreign bodies, surgical or nonsurgical interventions. In some cases, laryngeal injuries may be difficult to diagnose and evaluate. If the patient survives the primary traumatic event and his vital functions are preserved and stable, a careful laryngoscopic exploration--where indicated also such imaging procedure as high-resolution CT, direct microlaryngoscopy and laryngometry--should be applied to establish the diagnosis and decide on appropriate treatment.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
