Background and Objectives: Post-craniotomy infection is a real risk for patient recuperation, increasing morbity and mortality and for the health system. It has a high incidence of complications, reaching the mark of 11%, because of that it is important to know the risk factors to improve quality on treatment and patient recuperation. The main purpose of this article is to define the risks of this procedure; indicate surgical site infection and meningitis incidence; aim the main risk factors; and calculate the lethality of craniotomy. Methods: This is a retrospective cohort on six hospitals located in the city of Belo Horizonte. Data was gathered and analyzed to obtain post craniotomy incidences and risk factors. Results: Global infection incidence is 8.8%, surgical site infection incidence is 5.1% and meningitis is 2.3%. Lethality rate is 8.3%. Conclusion: The main risk factors observed is American Society of Anesthesiologists (ASA)
score > 2 and prosthesis; general anesthesia appeared as protector factor for the infection.
