Study of Traumatic Head Injuries Using Computed Tomography

Abstract

The aim of this retrospective research was to study traumatic head injury (THI) using CT scan and to classify the types of head trauma fractures and types of hemorrhages. Methods and Results: The current study included 53 THI patients (43/81.1%) males and 10/18.9% females) with positive and negative CT scan findings. A complete clinical history and patients’ data were taken from CT reports, which included age, gender, type of trauma, associated injury, and CT findings with their percentages. The study was carried out in Taif city in King Abdelaziz Hospital and King Faisal Hospital. The distribution of various etiologies of THI has shown that the most common etiology was road traffic accident (RTA) (45.3%). The typical age for THI was between 21 to 30 years old (26.4%). The distribution of the traumatic causes for each age group is shown in Table 1. The typical age for RTA was the age group of 11-20 years (33.3%), for falls – the age groups of 0-10 years (33.3%) and over 60 years of age (33.3%). The frequency of various CT findings of THI was as follows: intracranial hemorrhage (56.6%), fracture (39.6%), pneumocephalus (22.6%), contusion (22.6%), foreign body (11.3%), and proptosis (3.8%). The distribution of fracture cases, according to their types, was as follows: a linear fracture (76.2%), comminuted fracture (23.8%), basilar fracture (14.3%), and depressed fracture (9.5%). The frontal bone was the most affected site with fractures (30.7%). Conclusion: CT is an appropriate clinical modality used in the management of THI patients in the emergency department. CT has the advantage of being fast, safe, available, sensitive to most acute post-traumatic injuries, accurate in identifying the head abnormalities such as fractures and hemorrhage during the first 24 hours after injury, which is beneficial in the early assessment, therapy planning, monitoring, and long-term patient care.
