The contribution of Davide Giordano (1864-1954) to pituitary surgery: the transglabellar-nasal approach.
This report describes the fundamental contribution made by Davide Giordano, proposing the transglabellar surgical approach in a period in which transfacial and transbasal operative approaches to the pituitary gland were considered inadvisable because of their risk. His idea was to gain access through bilateral paranasal and frontal skin incisions, allowing removal of the ethmoid bone and the anterior wall of the sphenoidal cube. ⋯ The importance of his contribution was confirmed by Cushing, who reported his first use of the approach of Giordano in 1909 in a patient with a pituitary adenoma. The efforts of Giordano clearly inspired surgeons of his era to perform this operation clinically, giving impetus to the further development of neurosurgery.

Some adult patients with moyamoya disease have been treated successfully by indirect revascularization alone, although surgical indications and hemodynamic changes for these patients have not been fully explored. To examine surgical indications for this procedure, we studied the regional cerebral blood flow (rCBF) and angiographic findings in adult patients with moyamoya disease preoperatively and postoperatively. ⋯ We conclude that for the surgical treatment of adult patients with moyamoya disease, indirect procedures, mainly encephaloduroarteriosynangiosis, are recommended for patients with lower rCBF and no or negative vascular reactivity in the noninfarcted cortices, as well as for those who have no indication for the direct procedure. It is possible to determine these indications by a xenon-133 inhalation single photon emission computed tomographic study including an acetazolamide challenge test.
