In 1775, cranial osteomyelitis was first explained by surgeon Percival Pott as a collection of pus under the pericranium. Dr. Pott reported cranial osteomyelitis as a consequence of forehead trauma (bone contusion) and extradural hemorrhage 1) Later, it became known that the cause of such an infection was not an injury but the spread of infection from neighbouring structures, for example, paranasal sinuses. Meltzer and Kelemen first described skull base osteomyelitis (SBO) in 1959 in patients with a burn injury and osteomyelitis of the external auditory canal 2).
