Elective craneal trepanation

Cranial trepanation, also known as trepanning, is one of the oldest known surgical procedures in human history. It involves drilling or scraping a hole into the skull to expose the dura mater (the outer membrane covering the brain). Historically, this procedure was performed for various reasons, including medical, spiritual, and cultural purposes. Today, cranial trepanation is largely obsolete in modern medicine, except for certain highly controlled neurosurgical procedures. It is not considered a treatment for autism or any other neurological developmental disorder. Trepanation for autism, however, is not a recognized or legitimate treatment within the medical community and is considered extremely dangerous and unethical.
