Podcast 885: Penetrating Neck Injuries

Contributor: Ricky Dhaliwal MD

Educational Pearls:

  • Three zones of the neck with different structures and risks for injuries:

    • Zone 1 is the most caudal region from the clavicle to the cricoid cartilage

    • Zone 2 is from the cricoid cartilage to the angle of the mandible

    • Zone 3 is superior to the angle of the mandible

  • Zone 1 contains the thoracic outlet vasculature (subclavian arteries and veins, internal jugular veins), carotid arteries, vertebral artery, apices of the lungs, trachea, esophagus, spinal cord, thoracic duct, thyroid gland, jugular veins, and the vagus nerve.

  • Zone 2 contains the common carotid arteries, internal and external branches of carotid arteries, vertebral arteries, jugular veins, trachea, esophagus, larynx, pharynx, spinal cord, and vagus and recurrent laryngeal nerves

    • Lower risk than Zone 1 or Zone 3

  • Zone 3 contains the distal carotid arteries, vertebral arteries, jugular veins, pharynx, spinal cord, cranial nerves IX, X, XI, XII, the sympathetic chain, and the salivary and parotid glands

  • Hard signs that indicate direct transfer to OR:

    • Airway compromise

    • Active, brisk bleeding

    • Pulsatile hematomas

    • Hematemesis

    • Massive subcutaneous emphysema

  • Soft signs that may obtain imaging to determine further interventions:

    • Hemoptysis

    • Oropharyngeal bleeding

    • Dysphagia

    • Dysphonia

    • Expanding hematomas

  • Soft sign management includes ABCs, type & screen, and airway interventions followed by imaging of the head & neck area

  • Patients with dysphonia or dysphagia with subsequent negative CTAs may get further work-up via swallow studies
