IntroductionIn Nordic countries penetrating neck injuries (PNIs) are infrequent and management has traditionally been guided by surgeons' preferences. Some form of selective non-operative approach is currently practised in most urban trauma centres.ObjectiveTo examine demographic features and treatment outcome of non-ballistic penetrating neck injuries in southern Finland and provide management guidelines for centres with low volume of penetrating neck trauma.Materials And MethodsRetrospective analysis of 85 platysma penetrating neck injuries in two southern Finland hospitals (Helsinki University Central Hospital, HUCH and Tampere University Hospital, TaUH) was carried out using the ICD-10 based hospital databases to identify PNI-patients.ResultsThe incidence of admitted patients with penetrating neck injuries was 1.3/100000/year. Fifty-two (61%) injuries were caused by random acts of violence, 28 (38%) were self-inflicted and 5 (6%) were accidents. Of all 85 patients, 52 (61%) underwent operative exploration with a negative exploration rate of 65%. Hard signs for vascular or aerodigestive trauma were present in 23 (27%) patients and all of these were operated with a negative exploration rate of 30%. Two patients had no hard signs on physical examination but were operatively explored and significant injuries were found in both patients. The hospital mortality rate was 0% and the overall complication rate for operated patients was 7.7%.ConclusionsTrauma centres managing PNIs infrequently should have an individually tailored management protocol for penetrating neck injury patients. If mandatory exploration is not practised, a systematic physical examination should be the mainstay of diagnostic work up but the threshold for adjunctive studies should be low. Although not evident by the current data, protocol-based management could be useful in decreasing treatment variation and enhancing residency training.
