Abstract: Introduction/Aims: To study cranial nerves injuries (CNIs) incidence in patients with mild traumatic brain injury (TBI) in a tertiary healthcare Centre. Methods: In this study, 181 patients with mild TBI were included during a period from December 2019 to June 2021. The incidence of CNIs was immediately performed on the patients and they were examined daily until the day of discharge. TBI severity was evaluated using Glasgow Coma Scale (GCS) score. The incidence of CNIs and their correlation to the mode of injury, the type and severity of head injury, and radiological findings were investigated. Results: The incidence of CNIs in patients with mild TBI was 55.8%. The incidence of single CNI resulted 30.9%, whereas multiple CNIs was reported in 24.9% of patients with mild TBI. The most common cranial nerve injured was the olfactory nerve (28.2%), followed by the seventh cranial nerve (23.28%). Cranial nerve injury associated with skull fracture had a relatively poor outcome. In mild head injury, the involvement of 5th and lower cranial nerve (nine, ten, eleven and twelve) injuries is quite rare. Discussion: The main cause of CNIs is motor vehicle accidents and middle - aged males are disproportionately affected. This study also emphasizes the significance of a thorough clinical examination for cranial nerve injury in head injury patients and the urgency of prompt medical intervention.
