BackgroundOpen wounds to the head with skull bone depression pose the potential for serious injuries to the brain parenchyma and an increased risk of infection. The treatment of these injuries aims to repair the breached dura as well as remove any nidus for infection. Open wounds to the head due to bullets pose special problems and have a high fatality rate.AimTo review the presentation, management and outcome of depressed and penetrating open fractures of the skull in Port Moresby.MethodAll cases seen from 2003 to 2005 were included. All were managed without a CT (computed tomography) scan. Their Glasgow Outcome Scale (GOS) was documented on discharge.ResultsThere were 340 traumatic brain injury (TBI) cases over a period of 3 years between 2003 and 2005 managed by the Neurosurgery Unit of Port Moresby General Hospital. The open depressed and penetrating skull fractures seen in these cases numbered 46 (14%), of which 42 were males and 4 females. The weapons most commonly used were blunt objects (16), knives (11), guns (6) and axes (4). Gunshots contributed to 4 of the 7 deaths. 4 out of the 7 deaths were due to primary brain injury and 3 were due to infection.ConclusionOpen depressed fractures and penetrating injuries form a small but significant group in the management of head injuries. The use of blunt objects, firearms and arrows coupled with increasing urban violence is responsible for most of these injuries. The outcome of patients admitted who are fully conscious is expected to be good. They can be managed by prompt debridement of the wound, elevation of the fracture and removal of fragments as appropriate. However, the mortality rate is high in those with a Glasgow Coma Score of 8 or less on admission, a finding indicative of the severity of brain injury beneath the wound.
