Gerard Guiot (1912–1998) was one of the most renowned and innovative [[neurosurgeon]]s 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

[[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

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
