The necessity of mandatory exploration of penetrating zone II neck injuries.
To reevaluate the validity of our policy of mandatory surgical exploration of penetrating zone II neck injuries, the charts of 110 patients who underwent surgical exploration for such injuries were reviewed. Fifty-three percent of the patients had normal findings at exploration, whereas 33% had injuries involving vascular structures of the neck and 14% had nonvascular injuries. Injuries were not suspected on clinical grounds preoperatively in 23% of the patients in whom surgical exploration revealed injury. The injuries most likely to escape preoperative diagnosis were isolated venous injuries and isolated pharyngoesophageal injuries. Arteriography yielded false-negative results in two arterial injuries. No deaths and only a 5% incidence of minor complications occurred in the group with no injuries detected at exploration. We conclude that surgical exploration of penetrating zone II neck injuries is safe and appropriate.
