Abstract

Brain abscesses caused by dental infections are rare but potentially fatal infections with a high mortality rate. Early diag nosis and treatment are crucial, but diagnosing them is not straightforward. Various mechanisms exist through which oral bacteria can spread to the central nervous system, with hematogenous dissemination being considered the most important pathophysiological mechanism. In this report, two cases of brain abscess originating from maxillofacial fascial space infec tion will be presented. In the first case, the infection originating from the right side secondary to the left brain abscess, and in the second case, the infection originating from the left side led to a secondary infection in the left brain abscess. In both cases, the source of the infection was traced back to dental issues. The patients showed improvement through long-term high dose antibiotic therapy and surgical treatment by oral & maxillofacial surgeon and neurosurgeon.
