In this enlightening piece, UpSurgeOn delves into the historical evolution of cranial surgery techniques, tracing the path from trepanation to the cutting-edge methods of today. Prepare to be amazed as we explore the remarkable advancements that have revolutionized patient care and safety.
Cranial neurosurgery during Ancient times
Throughout history, cranial surgery techniques have undergone significant evolution. Surprisingly, even ancient civilizations like the Incas, Mayans, and Egyptians practiced various forms of cranial surgery. The oldest known surgical technique, trephination, involved creating a hole in the skull to access the brain. Remarkably, studies on ancient trephined skulls have shown that many patients survived the procedure, indicating a level of knowledge in anatomy and proper surgical procedures [1 – 4]. Other surgical techniques, such as transnasal excerebration and cranioplasty, were also developed in ancient times  . These ancient practices laid the foundation for modern cranial surgery techniques.

Cranial neurosurgery during Renaissance and Advancements in the 19th Century
During the Renaissance, the art of cranial surgery continued to progress, with surgeons constantly refining their techniques. In the 16th and 17th centuries, even the smallest cranial lesions were treated through surgical procedures. However, it’s worth mentioning that these early surgeries were far from sophisticated. They were often performed without any form of anesthesia, and the instruments used were not properly sterilized . It wasn’t until the 19th century that significant breakthroughs in anesthesia, antisepsis, radiography, hemostasis, and new surgical tools truly revolutionized our understanding of the brain and its functions .
Yet, it’s important to note that the evolution of cranial surgery techniques was not solely dependent on medical advancements. The development of more precise cutting instruments, such as scalpels and saws, played a crucial role during this period. Additionally, specialized tools like trephines, which were used to create burr holes in the skull, were introduced. These innovative instruments allowed surgeons to perform cranial surgeries with greater accuracy and control, ultimately leading to improved outcomes for patients .
It is fascinating to see how both medical advancements and the development of surgical instruments worked hand in hand to shape the field of cranial surgery during this transformative period.
Cranial Neurosurgery during World Wars
During World Wars I and II, there were significant advancements in cranial surgery techniques due to the high number of cranial injuries sustained by soldiers. The experiences of wartime neurosurgeons played a crucial role in shaping the evolution of modern cranial surgery techniques  . During World War I, Harvey Cushing developed and implemented several specific surgical techniques for the treatment of brain wounds. These techniques included en bloc bone resection, primary closure, and the use of suction debridement. Cushing also standardized intracranial injuries into nine categories with separate mortality rates . He emphasized the importance of early, definitive intracranial surgery and the use of antiseptic techniques to decrease infection rates . Cushing’s contributions significantly reduced mortality rates and established him as a pioneer in the field of neurosurgery .
During World War II, several specific surgical techniques were developed to address the high number of cranial injuries sustained by soldiers . One significant advancement was the development of cranioplasty techniques using tantalum as the preferred material for cranial defect repair . Tantalum’s malleability facilitated a single-stage cosmetic repair of cranial defects. Additionally, there was a rapid evolution in prosthesis implantation and fixation techniques during this time . These advancements in cranial surgery techniques have shaped the way cranial surgeries are performed today [9 – 17].
Cranial neurosurgery in Modern times
In the past few years, cranial surgery techniques have undergone a remarkable transformation, thanks to the progress in technology, better comprehension of cranial anatomy and physiology, and the desire to enhance patient outcomes while minimizing invasiveness. Here are some of the significant breakthroughs:
- Endoscopic skull base surgery: Endoscopic techniques have revolutionized the field of skull base surgery, allowing for less invasive approaches and improved visualization of deep structures .
- Minimally invasive approaches: Surgeons are increasingly using minimally invasive techniques, such as keyhole craniotomy and neuroendoscopy, to reduce trauma to the surrounding tissues and promote faster recovery .
- Advanced imaging and navigation: The use of advanced imaging techniques, such as MRI and CT scans, combined with intraoperative navigation systems, allows surgeons to precisely plan and execute surgical procedures .
- Improved materials and implants: The development of new materials, such as bioabsorbable plates and polyetheretherketone (PEEK) implants, has improved the outcomes of cranial surgery by providing better stability and reducing the risk of complications .
- Multidisciplinary collaboration: The field of cranial surgery has seen increased collaboration between neurosurgeons, otolaryngologists, and other specialists, leading to a more comprehensive and coordinated approach to patient care .
