Current management of penetrating injuries of the soft palate

Abstract

Children present to emergency departments with soft palate impalement injuries on an infrequent though periodic basis. Although these usually heal without treatment, internal carotid artery thrombosis occurs on rare occasions due to vessel compression causing intimal disruption. Thirty-two cases have been reported in the English literature. Hospital observation for up to 72 hours had been recommended previously for all of these injuries because of a "lucid interval," usually present before onset of neurologic symptoms. Subsequent studies have shown a very low occurrence of carotid injury and support outpatient observation similar to that after minor head injury. This is further justified by the lack of evidence that any diagnostic study or therapeutic measure alters the ultimate prognosis and outcome. Laceration repair is suggested for retained foreign bodies, through and through injury, or if a large hanging flap is present. Antibiotic indications are not well defined but should be considered for lacerations over 1 to 2 cm in length.
