Objective:

To review the shift from traditional zonal management to selective, imaging-based management of penetrating neck injuries, highlighting its significance in reducing unnecessary surgeries.

Key Findings:

CTA has 90% to 100% sensitivity and 98.6% to 100% specificity for vascular injuries.
Sensitivity for aerodigestive injuries is 100% with 93.5% to 97.5% specificity.
Vascular injury occurs in up to 25% of cases, primarily affecting carotid arteries.
Aerodigestive injuries occur in 23% to 30% of cases, with mortality rates of 11% to 17%.
Overall mortality for penetrating neck injury is estimated at 3% to 6%, with half of deaths due to hemorrhage.

Interpretation:

The shift towards imaging-based management allows for safer observation of patients without detected injuries, thereby reducing unnecessary surgical interventions and improving patient outcomes.

Limitations:

Sensitivity for detecting pharyngoesophageal injuries may decrease to 53% near missile tracts, necessitating confirmatory studies like contrast esophagram and esophagoscopy, which can impact clinical decision-making.
