Materials used in cranioplasty: a history and analysis.
Cranioplasty, one of the oldest surgical procedures used to repair cranial defects, has undergone many revolutions over time to find the ideal material to improve patient prognosis. Cranioplasty offers cosmetic and protective benefits for patients with cranial defects. The first primitive cranioplasty procedures date back to 7000 bc and used metal and gourds to repair cranial defects. ⋯ Research now has shifted toward molecular biology to improve the ability of the patient to regenerate bone using bone growth factors. This paper reviews the evolution of materials used over time in addition to the various advantages and pitfalls associated with each change. It is important for neurosurgeons to be mindful of how these techniques have evolved in order to gain a better understanding of this procedure and how it has been adapted.

Craniosynostosis surgery: the legacy of Paul Tessier.
Paul Louis Tessier is recognized as the father of craniofacial surgery. While his story and pivotal contributions to the development of the multidisciplinary practice of craniofacial surgery are much highlighted in plastic surgery literature, they are seldom directly discussed in the context of neurosurgeons. His life and legacy to craniosynostosis and neurosurgery are explored in the present paper.

Craniotomies are among the oldest neurosurgical procedures, as evidenced by early human skulls discovered with holes in the calvaria. Though devices change, the principles to safely transgress the skull are identical. Modern neurosurgeons regularly use electric power drills in the operating theater; however, nonelectric trephining instruments remain trusted by professionals in certain emergent settings in the rare instance that an electric drill is unavailable. ⋯ This drill permitted surgeons to stock multiple bits, perform the craniotomy faster, and decrease equipment costs during a period of increased incidence of cranial fractures, and thus the need for craniotomies, which was attributable to the introduction of gunpowder. The inspiration stemmed from a school of thought growing within a population of physicians trained as mathematicians, engineers, and astrologers prior to entering the medical profession. Berengario may have been the first to record the use of such a unique drill, but whether he invented this instrument or merely adapted its use for the craniotomy remains clouded.
