Objective. The aim of this study was to describe the indications and results of exploratory burr hole performed at the Departmental Teaching Hospital of Borgou (Benin). Methods. It was a retrospective study performed from January 2008 to February 2011. It concerned patients with a closed traumatic brain injury (TBI) in which an exploratory burr hole was performed. The selection criteria were unilateral mydriasis associated with neurological deficits on the opposite side or the occurrence of a decreased consciousness associated with the appearance of a motor deficit after a lucid interval. Results. Amongst the 74 patients operated, 23 (31%) underwent an exploratory burr hole for which the average age was 24.8 ± 17.3 years. Sex ratio male/female was 3.6. TBI was due to road traffic accident (56.5%), a fall (26.1%), and an assault (17.4%). It was severe (47.8%), moderate (39.1%), and mild (13.1%). Mydriasis was observed in 69.6% of cases as well as neurological deficit in all patients. A lesion was observed in 15 (65.2%) cases. Conclusion. The exploratory burr hole seemed as an old practice, still no longer performed in full practice in Benin, and is a diagnosis and therapeutic approach. Better technical conditions would allow more relevant therapeutic options.
