Management of the carotid artery following penetrating injuries of the soft palate

Abstract

Penetrating injuries of the soft palate are not uncommon in the pediatric population. The majority are minor, requiring only conservative treatment. Despite the close proximity of the carotid artery to lateral soft palate and tonsillar fossa, the incidence of carotid injury is low. When carotid injury does occur, it is usually secondary to blunt trauma to the carotid with a resultant thrombosis. A concomitant neurologic deterioration often follows occurring from 3 h to 3 days after the initial injury (Hengerer et al. (1984). Laryngoscope 94, 1571-1575). The potential neurologic sequelae of such an injury make these seemingly innocuous wounds a diagnostic and management dilemma for the clinician. We present an unusual case of an internal carotid artery pseudoaneurysm in a neurologically intact child following soft palate impalement. We review the diagnostic evaluation including angiography and magnetic resonance angiography, the surgical approach, and postoperative issues including anticoagulation. The literature is reviewed and a discussion regarding the approach to penetrating injuries of the soft palate is presented.
