Archeological findings dating back to 6,500 bc suggest the first attempt to offer care for those suffering from mental illness took the form of trepanning.
A surgical procedure called trepanning involves drilling or scraping a hole into the human skull. It is also referred to as trepanation, trephination, trephining, or producing a burr hole. Pressure beneath the skull bone is relieved by the operation. The buildup of fluid, such as pus, blood, or even air, may be the cause of the pressure. A tiny aperture is made in the frontal sinus floor through a surgical technique called trepanation.
Trepanation is still used by neurosurgeons today, albeit for quite different purposes. The method is mostly employed to treat epidural and subdural hematomas.
