Aims and Objectives: Basal skull fracture (BSF) is rare in head injury (HI) patients and occasionally goes unnoticed which may lead to cerebrospinal fluid (CSF) fistula. With changing trends in HI, there is a need to reassess incidence and pattern of BSF pattern, CSF leak, meningitis, and management protocol, especially in this part of the world where detailed literature is lacking. Subjects and Methods: We closely followed adult patients admitted with BSF in our institute between January 2013 and December 2014. Associated clinical features were recorded. In case of CSF leak, detailed CSF study was done and patients were managed accordingly. Patients with persistent CSF leak were managed surgically. Results: During the study period, 194 of 5041 HI patients had evidence of BSF (3.85%). BSF was most commonly associated with moderate-to-severe HI (73.19%). About 81.44% patients were male and 29.9% were <30 years. Most common cause was road traffic accident (84.54%). Isolated anterior cranial fossa (ACF) fracture was most common (50%). About 63.92% patients had raccoon eyes. Forty-three patients had CSF leak with CSF rhinorrhea being more common. Culture of only 5 patients suggested bacterial meningitis. CSF leak lasted for more than 10 days in 8 patients, of which 4 patients required surgical repair. Conclusions: BSF is rare in victims of HI. It is more common in young adult males. ACF fractures are most common in our setup. Clinical signs of BSF are supportive but not definitive; high resolution computed tomography head is gold standard to detect BSF. CSF leak is rare and most of the cases can be managed conservatively. Leak persisting more than 7–10 days has high risk of developing meningitis and likely to need surgical intervention.
