A laryngeal lesion may be large enough to cause airway obstruction, resulting in asphyxia and sudden death.
The laryngeal lesion is usually above the vocal cords.
Laryngeal lesions associated with sudden death:
(1) laryngeal cyst
(2) cavernous laryngeal hemangioma
(3) polyp (inflammatory laryngeal, other)
Rapid change in size due to edema or hemorrhage within the lesion can trigger the event.
The mass may make oral endotracheal intubation difficult.
