Penetrating neck injuries: analysis of experience from a Canadian trauma centre.
OBJECTIVE
To study the demographics and treatment outcome of penetrating neck injuries presenting to a major trauma centre in order to develop a treatment protocol.


METHODS
A case review.


METHODS
A trauma centre at a tertiary care institution.


METHODS
One hundred and thirty consecutive patients who had 134 neck wounds penetrating the platysma and presented to the trauma service between 1979 and 1997.


METHODS
Surgical exploration or observation alone.


METHODS
The location of injury, patient management, number of significant injuries, duration of hospital stay and outcome.


RESULTS
Injuries were caused by stab wounds in 124 patients (95%) and gunshot wounds in 6 (5%). The location of injury was zone I (lower neck) in 20 cases (15%), zone II (midportion of the neck) in 108 (81%) and zone III (upper neck) in 5 (4%). The location was not recorded in 1 case. Fifty patients were managed by observation alone and 80 were managed surgically. Neck exploration in 48 asymptomatic patients was negative in 32 (67%). Significant injuries, including major vascular (12), nerve (13) and aerodigestive tract (19) injuries, were identified in 34 patients. Two of the 130 patients (1.5%) died of major vascular injuries. Seventy-six percent of significant injuries, including all zone II major vascular injuries, were symptomatic on presentation. The mean (and standard deviation) hospital stay for asymptomatic patients treated with observation alone and surgical exploration was similar (3.5 [6.02] versus 4.3 [5.46] days respectively, p = 0.575). Long-term disability, all neurologic in nature, was documented in 3 patients managed by observation alone and 6 patients managed by surgical exploration.


CONCLUSIONS
Penetrating neck trauma, in particular stab wounds to zone II in asymptomatic patients, is associated with low morbidity and mortality. A selective management protocol with investigations directed by symptoms is the most appropriate approach for the patient population and resource base in this setting.
