Abstract

Patients with penetrating wounds to the neck present with overt symptoms and/or signs or are asymptomatic or modestly/moderately symptomatic. With overt symptoms and/or signs, immediate resuscitation and an emergency operation are appropriate. Asymptomatic patients or those with modest or moderate symptoms and/or signs undergo observation or a diagnostic evaluation to avoid the 45% "negative" exploration rate documented in the past (denominator = all patients). Asymptomatic patients with penetration of the platysma muscle, but no signs of a visceral or vascular injury, should undergo serial physical examinations every 6-8 for 24-36 h before discharge. Noncontrast CT does not add to the accuracy of serial physical examinations. In stable patients with a variety of modest/moderate symptoms or signs possibly related to an injury to the carotid artery, CT-arteriography has become the diagnostic modality of choice. Patients with possible injuries to the cervical esophagus are often still evaluated with a Gastrografin swallow and, if needed, a "thin" barium swallow prior to fiberoptic esophagoscopy. CT-esophagograms are likely to replace these time-honored studies in the near future. Over 85% of patients with injuries to the trachea present with overt symptoms or signs, while the remainder have historically been evaluated with laryngoscopy and fiberoptic bronchoscopy. Again, cervical multislice CT is likely to replace these studies. Operative repair of the carotid artery with 6-0 polypropylene sutures requires heparinization and shunting on rare occasions. Both the trachea and esophagus are repaired with 3-0 absorbable sutures, and tracheostomy and esophageal diversion are used in only large and/or complex injuries. Sternal head or sternocleiodomastoid interposition flaps are used when combined visceral and vascular injuries are present.
