Face, neck, and eye protection: adapting body armour to counter the changing patterns of injuries on the battlefield.

Recent international papers have suggested an urgent need for new methods of protecting the face, neck, and eyes in battle. We made a systematic analysis to identify all papers that reported the incidence and mortality of combat wounds to the face, eyes, or neck in the 21st century, and any papers that described methods of protecting the face, neck, or eyes. Neck wounds were found in 2-11% of injuries in battle, and associated with high mortality, but no new methods of protecting the neck were identified. Facial wounds were found in 6-30% of injuries in battle, but despite the psychological effects of this type of injury only one paper suggested methods for protection. If soldiers wore existing eye protection they potentially reduced the mean incidence of eye injuries in combat from the 4.5% found in this analysis to 0.5%. Given the need to balance protection with the functional requirements of the individual soldier, a multidisciplinary approach is required. Military surgeons are well placed to work with material scientists and biomechanical engineers to suggest modifications to the design of both personal and vehicle-mounted protection. Further research needs is needed to find out how effective current methods of protecting the neck are, and to develop innovative methods of protecting the vulnerable regions of the neck and face.
