Surgery of the human cerebrum--a collective modernity

Beneath the surface: A historical exploration of trepanation practices across cultures and eras

This research article explores the ancient origins of trepanation, unravelling its early instances and the associated cultural beliefs that have shaped cranial surgery. It scrutinises the medieval and Renaissance periods, elucidating the evolution of trepanation techniques within the context of advancements in medical knowledge and societal changes. In addition, the research investigates the diverse practices of trepanation across cultures, offering insights into the unique approaches, beliefs and rituals associated with this ancient surgical procedure. Examining the decline of trepanation in mainstream medicine, the article assesses the factors contributing to its diminishing prevalence and the emergence of alternative surgical methods. The study also delves into sporadic resurgences of trepanation in unconventional contexts, providing a nuanced understanding of its enduring fascination. In exploring trepanation's impact on modern medicine, the article sheds light on its contributions to the study of cranial anatomy, the evolution of surgical tools and the broader narrative of medical progress. Ultimately, this historical investigation contributes to a comprehensive understanding of trepanation, revealing the intricate interplay between medicine, culture and the human quest for knowledge and healing.

The brainstem and its neurosurgical history

Brainstem is one of the most complex structures of the human body, and has the most complex intracranial anatomy, which makes surgery at this level the most difficult. Due to its hidden position, the brainstem became known later by anatomists, and moreover, brainstem surgery cannot be understood without knowing the evolution of ideas in neuroanatomy, neuropathology, and neuroscience. Starting from the first attempts at identifying brainstem anatomy in prehistory and antiquity, the history of brainstem discoveries and approach may be divided into four periods: macroscopic anatomy, microscopic anatomy and neurophysiology, posterior fossa surgery, and brainstem surgery. From the first trepanning of the posterior fossa and later finger surgery, to the occurrence of safe entry zones, this paper aims to review how neuroanatomy and brainstem surgery were understood historically, and how the surgical technique evolved from Galen of Pergamon up to the twenty-first century.

Protecting the blossoming brain - Neurocritical care in children

This special issue of the Biomedical Journal is entirely dedicated to the latest updates regarding the medical efforts to preserve the fragile young brain after injury. Thereby, we learn about symptoms and diseases such as different forms of epilepsy, acute encephalopathy, increased intracranial pressure, and posthaemorrhagic hydrocephalus, as well as about their origins, such as infection, autoimmune diseases, preterm birth, or abusive head trauma. Moreover, diagnosis and surveillance techniques are discussed, including ultrasound of the optic nerve sheath diameter and multimodal monitoring. Finally, we discover various established and emerging therapeutic approaches, comprising target temperature management, ketogenic diet, and immunomodulation.

Prehistoric skull trepanation in China

The term trepanation describes the removal of sections of bone from the cranium. Although others may have made earlier reference to trepanation, in 1995, Chinese archeologists discovered a skull at the Neolithic site Fujia from approximately 3000 bc (the Dawenkou Cultural Period), Guangrao, Dongying, Shandong, China, and after careful examination of the specimen, the archeologists suggested that the procedure had been performed on a living patient who subsequently survived. Archeological evidence supports that the practice of trepanation was widespread.

A Bosphorus submarine passage and the reinvention of neurosurgery

One of the major themes characterizing the emergence of modern neurosurgery has been the concept of technology transfer and the application of a broad spectrum of revolutionary elements of technology from both physical and biological science. These transference applications are now apparent in modern neurosurgery as it is practiced on all continents of the globe. More than 3 decades ago, these ideas that now have come to fruition were in states of formulation. This article describes and further documents one such fertile cauldron of ideas and practical realities--the United States Navy Nuclear Submarine Service and its role and affect on the life and professional career of an academic neurosurgeon who was active in areas of progress as modernity was established for the early 21st century.
