Gerard Guiot

Gerard Guiot (1912–1998) was one of the most renowned and innovative neurosurgeons of the 20th century. His pivotal and revolutionary role in advancing transsphenoidal surgery has been recorded in many historical vignettes, yet his outstanding contributions to the advancement of neurosurgery outside the confines of the sella have not been described in a detailed fashion.

In a article, Krisht et al., discuss the life and achievements of Professor Guiot and present a comprehensive description of his contributions to the field of neurosurgery, including cerebrovascular, spine, craniofacial, stereotactic functional, and endoscopic surgery ¹⁾.

Gerard Guiot, inspired by Norman McOmish Dott, adopted his technique and used intraoperative radiofluoroscopic technique for image guidance. Jules Hardy, a fellow of Guiot, from Montreal, Canada, revolutionized transsphenoidal microsurgery with the introduction of the binocular microscope and selective adenomectomy ²⁾.

Gerard Guiot is recognized as the first neurosurgeon to use the endoscope in the transsphenoidal approach, although he abandoned the procedure because of inadequate visualization ^{3) 4)}
