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).
The term laser thermotherapy is an acronym for Light Amplification by Stimulated Emission of Radiation, which first appeared as a term in 1959. Laser thermal therapy was clinically used for tissue ablation in 1966, based on the theory that the energy produced by laser light could achieve a high peak power through a ruby tip and could be absorbed by the surrounding tissue as heat 3).
Steroid myopathy is usually an insidious disease process that causes weakness mainly to the proximal muscles of the upper and lower limbs and to the neck flexors. Cushing originally described it in 1932, and Muller and Kugelberg first studied it systemically in 1959.
