Trepanning , also known as trepanation , trephination , trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon , literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull . The intentional perforation of the cranium exposes the dura mater to treat health problems related to intracranial diseases or release pressured blood buildup from an injury. It may also refer to any " burr " hole created through other body surfaces, including nail beds. A trephine is an instrument used for cutting out a round piece of skull bone to relieve pressure beneath a surface.

140-435: A Competency to Stand Trial evaluation . In modern times, labeling someone as insane often carries little or no medical meaning and is rather used as an insult or as a reaction to behavior perceived to be outside the bounds of accepted norms. For instance, the definition of insanity is sometimes colloquially purported to be "doing the same thing over and over again and expecting a different result." However, this does not match
210-425: A personality disorder for the purposes of an insanity defense. The second question is whether the mental illness interfered with the defendant's ability to distinguish right from wrong. That is, did the defendant know that the alleged behavior was against the law at the time the offense was committed. Additionally, some jurisdictions add the question of whether or not the defendant was in control of their behavior at
280-537: A trephine -like tool. Additionally, bone regeneration and smooth edges suggest that the subject recovered from the surgery and lived a relatively long time afterward. The 3,600-year-old perforated skull of a mummified female dating to 1615 BCE was found in the Xiaohe tomb in China's Xinjiang Uygur Autonomous Region . The only known female with a trepanned skull, it showed signs of bone spurs growth and retraction of
350-513: A charm to keep evil spirits away. Evidence also suggests that trepanation was primitive emergency surgery after head wounds to remove shattered bits of bone from a fractured skull and clean out the blood that often pools under the skull after a blow to the head. Hunting accidents, falls, wild animals, and weapons such as clubs or spears could have caused such injuries. Trepanations appear to have been most common in areas where weapons that could produce skull fractures were used. The primary theories for

It is unclear if this was performed as a veterinary procedure , medical experimentation or for other unknown reasons. However, It could be the earliest archaeological example of veterinary surgery or animal medical experimentation. In the more recent times of postclassical pre-Columbian Mesoamerica , evidence for
490-454: A hole in the skull will let out the evil spirits that caused pain and illness. It can be explained as most head injuries and diseases, such as migraine, felt like pounding, so cutting a hole in head may help to relieve the pain and pressure. In Africa and Europe, not only this procedure was performed for spiritual reasons, but also the discs made of cranial bones were commonly used as shield from demons and evils. In China, twelve shaman corpses in
560-610: A license after they performed a trepanation on an English woman to treat her chronic fatigue syndrome and depression . In 2023, Michael Raduga, a Russian lucid dreaming researcher, performed self-neurosurgery that included trepanation, electrode implantation, and electrical stimulation of the motor cortex. The goal was to stimulate the brain during REM sleep, sleep paralysis, and lucid dreams. Modern forensic and medical research on trepanned skulls demonstrates advanced surgical skills in prehistoric societies and highlights how trepanation influenced later developments in neurosurgery and
630-412: A manner similar to cerebral vasodilators such as ginkgo biloba . These claims are unsubstantiated by research. Huges and his girlfriend also made several comic books in the 1970s, which promoted trepanation. In a chapter of his book Eccentric Lives & Peculiar Notions , esotericist John Michell cites Huges as pioneering the idea of trepanning in his 1962 monograph, Homo Sapiens Correctus , which
700-445: A person or persons becoming a danger to themselves or to other people. Conceptually, mental insanity also is associated with the biological phenomenon of contagion (that mental illness is infectious) as in the case of copycat suicides . In contemporary usage, the term insanity is an informal, un-scientific term denoting "mental instability"; thus, the term insanity defense is the legal definition of mental instability. In medicine,
770-407: A physician or surgeon to relieve the pain associated with a subungual hematoma (blood under the nail); a small amount of blood is expressed through the hole and the pain associated with the pressure is partially alleviated. Similarly, in abdominal surgery, a trephine incision is when a small disc of abdominal skin is excised to accommodate a stoma . Although the abdominal wall does not contain bone,

Even so, some evidence of genuine trepanation in Mesoamerica (i.e., where the subject was living) has survived. The earliest archaeological survey published of trepanned crania was a late 19th-century study of several specimens recovered from the Tarahumara mountains by
910-501: A tomb were found with trephined bodies because they also had duties of doctors. This tells about connection of cranial surgery to religion; there was conception that open hole in head contributes to communication with god and souls of dead people. Trepanation was also associated in Chinese medicine with the balance of vital energy, or qi. They understand trepanation as a way to balance the body and energy, spiritual and physical health. On

This was a widespread tradition, illustrated in pre-Columbian art that occasionally depicts rulers adorned with or carrying the modified skulls of their defeated enemies, or of the ritualistic display of sacrificial victims. Several Mesoamerican cultures used

The disorders formerly encompassed by the term covered a wide range of mental disorders now diagnosed as bipolar disorder , organic brain syndromes , schizophrenia , and other psychotic disorders. In United States criminal law , insanity may serve as an affirmative defense to criminal acts and thus does not need to negate an element of
1120-437: Is not caught and treated immediately, it can be fatal or lead to significant and permanent brain damage. After surgery, neither the surrounding bone nor the trepanned bone piece ever show any osseous healing like other bones. Osteoclastic and osteoblastic activity occurs after the first week; hyperemia and osteoclastic activity are seen on the necrotic bone surrounding the trepanation site, due to loss of blood supply. Since
1190-534: Is not consistent. One of the reasons of distinction in variations of healing process is difference of surgical methods such as “scraping” or “grooving” that might alter the angle of the edge. The first smoothening of bone begins in 5 months, but total healing or closure never happens. By the 20th century, the ancient practice of trepanning evolved into procedure of bone marrow biopsy, which became vital for identifying illnesses including anemia, leukomia, lymphoma, and tuberculosis. This change happened as doctors realized
1260-534: Is now known as Ica, located south of Lima. Trepanation has also been found in the Muisca Confederation (in modern-day Colombia) and the Inca Empire . In both, even cranioplasty existed. The prevalence of trepanation among Mesoamerican civilizations is much lower, at least judging from the comparatively few trepanned crania that have been uncovered. The archaeological record in Mesoamerica
1330-430: Is often cited by advocates of self-trepanation. Among other arguments, Huges contends that children have a higher state of consciousness and since children's skulls are not fully closed, one can return to an earlier, childlike state of consciousness by self-trepanation. Further, by allowing the brain to freely pulsate Huges argues that a number of benefits will accrue. Michell quotes Joey Mellen's book, Bore Hole . At

A small area near (modern) Rostov-on-Don , in southern Russia, may have been a centre for ritual trepanning, around 6000 years ago, according to archeologists who discovered remains of eight recipients of the practice, within a small area, all with the incision in the unusual obelion position, high on the back of the head. During the 16th and 17th centuries, around 80% of people survived

#17327802568651540-718: The Yucatán Peninsula show no evidence of the drilling or cutting techniques found in central and highland Mexico. Instead, the pre-Columbian Maya apparently used an abrasive technique that ground away at the back of the skull, thinning the bone and sometimes perforating it, similar to the examples from Cholula. Many skulls from the Maya region date from the Postclassic period ( c. 950–1400 CE ), and include specimens found at Palenque in Chiapas , and recovered from
1610-540: The occipital bones. In most cases, trepanation was a one-off operation, with only a small percentage of the trepanned skulls having undergone more than one surgery. In those with multiple openings, the extent of bone remodelling helps identify whether the opening was done at around the same time or at different times during the individual's life. A neurosurgeon can perform the procedure safely, although it comes with severe repercussions such as direct or indirect perioperative complications, which include increased damage to
1680-576: The 20th century, patient survival rate was seen to be approximately 90%. After the retrieval of some skulls from the Neolithic era that showed signs of trepanation, in the nineteenth century, the false belief that these holes were drilled for the treatment of headaches or other neurological disorders started spreading. During the 1870s, the French anthropologist and physician Paul Broca found several European and South American children's skulls dating to
1750-496: The Neolithic age that were perforated surgically. Since no signs of fractures that could justify this complex procedure to relieve trauma were found, a debate emerged around why these children were subjected to trepanation while they were still alive. Broca theorized that this operation had a ritual or religious purpose, probably to remove "confined demons" inside the head of the patient, or to create healing or fortune talismans with
1820-672: The Norwegian ethnographer Carl Lumholtz . Later studies documented cases identified from a range of sites in Oaxaca and central Mexico , such as Tilantongo , Oaxaca and the major Zapotec site of Monte Albán . Two specimens from the Tlatilco civilization's homelands (which flourished around 1400 BCE) indicate the practice has a lengthy tradition. Specimens identified from the Maya civilization region of southern Mexico, Guatemala and

A more informal use of the term insanity is to denote something or someone considered highly unique, passionate or extreme, including in a positive sense. The term may also be used as an attempt to discredit or criticize particular ideas, beliefs, principles, desires, personal feelings, attitudes, or their proponents, such as in politics and religion. Madness,

Over time, the skin will reform over the puncture site, but the hole in the skull will remain. The location of the trepanation on the skull varies by geographical region and period, common locations are the frontal and
2030-409: The basis of today's theory of psychosomatic illness. The Romans also supported humane treatment of the mentally ill, and in so doing, codified into law the principle of insanity as a mitigation of responsibility for criminal acts, although the criterion for insanity was sharply set as the defendant had to be found " non compos mentis ", a term meaning "not sound of mind". The Middle Ages witnessed
2100-407: The brain, infection, blood loss, hemorrhage, and potentially death due to the trauma as the skull's protective covering is compromised. The operation leaves very minimal space for error and a high incidence of mortality if the dura mater is penetrated. Additionally, there is a high risk of infection if the operation is conducted with contaminated tools or improper sanitary wound care. If the infection

Additionally, the specially designed drills come with a safety feature that prevents the drill from penetrating into the brain tissue (through the dura mater). Along with antisepsis and prophylaxis of infection, modern neurosurgery is a common procedure for many reasons other than head trauma.

By the Renaissance period, when trepanation was routinely performed, a range of instruments were developed to accommodate the demand. As many as five main methods were found for trephination: The scraping method was found to be the most common in prehistoric times. The differences in method vary in
2310-597: The early 1960s, voluntary trepanation has been performed by people interested in "enhancing mental power and well-being". The practice of trepanning also continues today due to belief in various pseudoscientific medical benefits. For example, some have tried trepanation as a means of emulating the " third eye ", in order to achieve clairvoyance or as a means of maintaining a "permanent state of euphoria ". Other proponents claim that trepanning results in increased blood flow. Individuals have practiced non-emergency trepanning for psychological purposes. A prominent proponent of

During the 18th century, the French and the British introduced humane treatment of the clinically insane, though the criteria for diagnosis and placement in an asylum were considerably looser than today, often including such conditions as speech disorder , speech impediments, epilepsy , and depression or being pregnant out of wedlock. Europe's oldest asylum

Other modern practitioners of trepanation claim that it holds other medical benefits, such as relief from depression and from other psychological ailments. In 2000, two men from Cedar City, Utah , were prosecuted for practicing medicine without
2590-411: The final decision regarding the defendant's status regarding an insanity defense . In most jurisdictions within the United States, if the insanity plea is accepted, the defendant is committed to a psychiatric institution for at least 60 days for further evaluation, and then reevaluated at least yearly after that. Insanity is generally no defense in a civil lawsuit, but an insane plaintiff can toll
2660-510: The general term psychosis is used to include the presence of delusions and/or hallucinations in a patient; and psychiatric illness is " psychopathology ", not mental insanity . In English, the word "sane" derives from the Latin adjective sanus , meaning "healthy". Juvenal 's phrase mens sana in corpore sano is often translated to mean a "healthy mind in a healthy body". From this perspective, insanity can be considered as poor health of
2730-442: The history of medicine. With the advancement of technology, it became possible to examine and interpret the trepanned skull with CT scans and new techniques of bioarchaeology. A recent study provided new perspective of the healing process of skull after cranial trepanation: even though there are many examples of prehistoric cranial lesions that have been classified as "healed trepanations", the research shows that definition of “healing”
2800-429: The infection rate was low. In the graveyards of pre-Christian ( Pagan ) Magyars , archeologists found a surprisingly high frequency (12.5%) of skulls with trepanation, although more than 90% only partial (these served probably ritual purposes). The trepanation was performed on adults only, with similar frequencies for males and females, but increasing frequency with age and wealth. This custom suddenly disappeared with

One of the most prominent advocates of trepanning was Dutch librarian Bart Huges . In 1965, Huges drilled a hole in his own head with a dentist drill as a publicity stunt. Huges claimed that trepanning increases "brain blood volume" and thereby enhances cerebral metabolism in

The typical techniques as outlined in these works are the background for Dr. Neil S. Kaye's widely recognized guidelines that indicate an attempt to feign insanity. One famous example of someone feigning insanity is Mafia boss Vincent Gigante , who pretended for years to be suffering from dementia, and
3290-425: The myth persists. The motivations behind trepanation varied significantly across cultures, often tied to beliefs about health, spirituality, and the treatment of ailments. Early instances of the practice may have been influenced by a combination of supernatural beliefs and early understandings of physical ailments, leading to its acceptance in various medical traditions. In many cultures, it was believed that drilling

Some traditional cultures have turned to witch doctors or shamans to apply magic, herbal mixtures, or folk medicine to rid deranged persons of evil spirits or bizarre behavior, for example. Archaeologists have unearthed skulls (at least 7000 years old) that have small, round holes bored in them using flint tools. It has been conjectured that

Trepanation would have been done in order to allow spirit to return back into body. In these cases, the patient may have suffered from paralysis, cerebral palsy, severe depression, or mental retardation. In ancient times, trepanation instruments were less complex, and were commonly made out of flint, obsidian, or harder material such as stone knives, and later with metal such as bronze and copper. Additionally,
3500-535: The practice of trepanation and an assortment of other cranial deformation techniques comes from a variety of sources, including physical cranial remains of burials, allusions in iconographic artworks and reports from the post-colonial period. Among New World societies, trepanning is most commonly found in the Andean civilizations, such as pre- Incan cultures. For example, the Paracas culture Ica , situated in what

#17327802568653640-553: The procedure of trepanation. The prefrontal leucotomy, a precursor to lobotomy , was performed by cutting a trephine hole into the skull, inserting an instrument, and destroying parts of the brain. This was later made unnecessary by the development of the orbital transit lobotomy where a spike was inserted through the eye-sockets. Trepanation is a treatment used for epidural and subdural hematomas , and surgical access for certain other neurosurgical procedures, such as intracranial pressure monitoring. Modern surgeons generally use
3710-408: The procedure was done by practitioners utilizing tumi (ceremonial knife in early Peru), sharpened seashells (South Pacific), a trephine drill, bronze knife, etc. The Greeks and Romans were the first to design medical instruments that were used to penetrate the skull. Such instruments includes the terebra serrata , made to perforate the cranium by positioning the instrument's pointed end against

However, he also suggested that the operation may have been performed to treat some infantile conditions such as febrile seizures to explain why it was performed only on children. Broca never mentioned headaches, though, and the association was established only several decades later by the world-famous Canadian physician William Osler in 1913. Osler misinterpreted Broca's words, and added other conditions such as "infantile convulsions, headache and various cerebral diseases believed to be caused by confined demons." Osler's theory
3990-639: The site of the operation. Trepanning at the Kisii people in Kenya was filmed in 1958. Trepanation was known to prehistoric Europeans, with some populations having impressive success rates of 78% in the Iron Age. Trepanation was also practised in the classical and Renaissance periods. Hippocrates gave specific directions on the procedure from its evolution through the Greek age, and Galen also elaborates on

Amongst other purposes, insanity is feigned in order to avoid or lessen the consequences of a confrontation or conviction for an alleged crime. A number of treatises on medical jurisprudence were written during the nineteenth century,

More recent research on the historical practice of trepanning supports the hypothesis that this procedure was medical in nature and intended as means of treating cranial trauma. The Greeks appeared to share something of the modern Western world's secular and holistic view, believing that afflictions of

Trepanation dates back to 7,000–10,000 years ago, is perhaps the oldest surgical procedure for which there is archaeological evidence, and in some areas may have been quite widespread. The main pieces of archaeological evidence are in the forms of cave paintings and human remains.
