Magnitude of dural tear and its associated factors among patients with depressed skull fracture.

Abstract

Trauma is a huge problem seen in developed countries as well as developing countries. Head injury is a major factor responsible for mortality in young populations. Up to 6% of all head injuries and 11% of severe head traumas might result in a depressed skull fracture (DSF), a catastrophic injury. The aim of this study was to determine the prevalence of dural tear and to identify its predictors. A retrospective review of medical records of all patients operated on for DSFs at the University Comprehensive Specialized Hospital from 1 January 2021 to 1 January 2023 G.C. (Gregorian calendar) was conducted. A total of 163 patients were included in the study. A total of 163 patients [136 men (83.4%) and 27 women (16.6%)] had a mean age of 23.9 with a standard deviation of 14.8 (range from 3 to 65). Patients with penetrating injuries (missiles, axes) were excluded. The majority, 153 (93.9%) of the patients, were younger than 50 years of age. Physical assault accounted for 102 (62.5%) of the cases. Of the assaulted cases, 62 (38%) were assaulted by stone, 32 (19.6%) by stick, and 8 (5%) by other objects (beer bottle and shovel). Bleeding from the trauma site in 124 (76.1%), headache in 76 (46.6%), loss of consciousness in 75 (46%), and vomiting in 72 (44.2%) were the most common presentations. Based on the Glasgow Coma Scale (GCS), 123 (75%) patients had mild head injuries. Based on the site of fracture, frontal depressions are the most common (61, 37.4%), followed by parietal depressions (53, 32.5%). With regard to the associated injuries, brain contusion was seen in 52 (32%), epidural hematoma (EDH) in 26 (16%), subdural hematoma in 3 (1.8%), and intraventricular hemorrhage/subarachnoid hemorrhage (IVH/SAH) in 3 (1.8%). The median duration of presentation was 15h, with an interquartile range (IQR) of 8-24 (1-96h). From the multivariable logistic regression, brain contusion and EDH were significantly associated with dural tear. The rules of our culture are reflected in the higher incidence of accidents and fractures among men. Physical assault, particularly with stones, was the most common cause of DSFs. Frontal depressions were the most common site of fracture, followed by parietal fractures. Brain contusion and EDH were significantly associated with dural tears. School-aged children are more vulnerable to injuries from horse or donkey kicks and falls.
