Imagine playing a violin while undergoing brain surgery. Sounds incredible, right? This is exactly what happened to a musician during her brain operation. This unique procedure is known as an awake craniotomy.
In an awake craniotomy, the patient is initially sedated as the surgeon makes an incision in the scalp and removes a section of the skull. Once this is done, the patient is awakened to be conscious during the surgery. Interestingly, the brain itself doesn’t feel pain because it lacks nociceptors, which are the nerve endings responsible for detecting pain.
Being awake allows the surgeon to interact with the patient, asking questions or having them perform simple tasks. This ensures that critical functions like speech and motor skills remain unaffected during the operation.
Craniotomies have a long history, with evidence of skull perforations dating back to the Neolithic period. The first written record of a craniotomy comes from Hippocrates in the 5th century BCE, who described its use in treating epilepsy. This practice continued for nearly 2,000 years.
The modern version of awake craniotomy became popular in the 1920s, thanks to advancements in anesthesia that allow patients to be sedated at the beginning and end of the procedure.
Meet Dagmar Turner, a violinist diagnosed with a brain tumor in her right frontal lobe, an area crucial for coordinating her left arm and hand movements. To ensure her motor functions were preserved, she played the violin while the surgeon operated.
While this method might seem basic, it has significantly evolved. Surgeons now use functional MRIs (fMRIs) to map brain activity before surgery, providing detailed information about the patient’s brain. However, fMRIs have limitations, as they may not always provide a clear picture, and the brain can shift during surgery.
The next big step in brain surgery is intraoperative MRIs, which allow doctors to take real-time images during the procedure. This helps them distinguish between tumor and healthy tissue, ensuring they remove all problematic areas.
Some doctors are exploring even more advanced techniques, such as placing sensors directly on the brain to measure electrical signals. Robotics are also becoming an integral part of neurosurgery, assisting surgeons in performing delicate operations within MRI machines.
Awake craniotomy has been a reliable technique for thousands of years, ensuring smoother surgeries. Surgeons are continually seeking to improve this method and its associated technologies to enhance treatments for conditions like epilepsy and Parkinson’s disease.
In a positive outcome, doctors successfully removed over 90% of Dagmar Turner’s tumor, including the most aggressive areas, and she retains full function of her left hand. She will continue to play the violin for years to come.

This is the sound a violin makes when it’s being played by someone who’s undergoing brain surgery. This musician is awake and playing her violin during her own brain operation. But why? This procedure is called an awake craniotomy.
In an awake craniotomy, a patient is initially sedated while the surgeon makes an incision in the scalp and drills into the skull to remove a section of bone. After this, the patient is brought out of sedation so they can be conscious during the surgery. Interestingly, the brain itself doesn’t feel pain because it lacks nociceptors, the nerve endings that detect pain.
So, why does the patient need to be awake? The surgeon can ask the patient questions or have them perform basic movements to ensure that the surgery isn’t affecting critical functions, such as speech or motor skills.
Craniotomies have been performed since ancient times. The first archaeological evidence of intentional skull perforations dates back to the Neolithic period. The earliest written record of a craniotomy is attributed to Hippocrates in the 5th century BCE, who provided guidelines for its use in treating epilepsy. This practice continued for about 2,000 years.
The modern practice of awake craniotomy gained popularity in the 1920s, thanks to advancements in anesthesia that allow patients to be sedated at the beginning and end of the procedure.
Now, let’s talk about the violinist, Dagmar Turner, who was diagnosed with a brain tumor located in her right frontal lobe, an area that controls coordination in her left arm and hand—the very parts she uses to play the violin. To ensure her motor functions were preserved, the surgeon asked her to play while he operated.
While this method may seem primitive, it has evolved significantly. Surgeons now use functional MRIs to map brain activity before surgery, providing specific information about the patient’s brain. However, fMRIs have limitations, as they may not provide the clearest picture, and the brain can shift during surgery.
The next advancement in brain surgery is intraoperative MRIs, which allow doctors to take real-time images during the procedure. This helps them differentiate between tumor and healthy tissue and ensures they remove all problematic areas.
Some doctors are exploring even more advanced brain mapping techniques, including placing sensors directly on the brain to measure electrical signals. Additionally, robotics are becoming integral to neurosurgery, with robots assisting surgeons in performing delicate operations within MRI machines.
Awake craniotomy has been a reliable technique for thousands of years, ensuring smoother surgeries. Surgeons are continually looking to improve this method and its associated technologies to enhance treatments for conditions like epilepsy and Parkinson’s disease.
In good news, doctors successfully removed over 90% of Dagmar Turner’s tumor, including the most aggressive areas, and she retains full function of her left hand. She will continue to play the violin for years to come.
