Occult craniocerebral injuries from dog bites in young children

Although dog bite injuries to the head and scalp of children occur frequent ly, penetrating dog bite wounds to the cranial vault occur only occasionall y and may go unnoticed on initial examination. Substantial morbidity and mo rtality can ensue if these penetrating injuries are not detected and treate d. The authors detail the evaluation of dog bites of the scalp in young chi ldren. They highlight the ease with which puncture wounds of the calvarium may be missed during physical examination as a result of scalp displacement at the time of puncture. The cranial puncture may not be large and may lat er be covered by scalp that returns to its native position. Well-scrutinize d skull films and a careful, methodical physical examination are advocated. Recognized craniocerebral injuries should be explored. Depressed cranial f ractures should be irrigated, debrided, and elevated. Dural tears should be repaired. Expedient management is necessary to prevent meningitis and its associated sequelae.
