Quantitative Anatomic Comparison of Microsurgical Transcranial, Endoscopic Endonasal, and Transorbital Approaches to the Spheno-Orbital Region.
[BACKGROUND] The spheno-orbital region (SOR) is a complex anatomic area that can be accessed with different surgical approaches. [OBJECTIVE] To quantitatively compare, in a preclinical setting, microsurgical transcranial approaches (MTAs),…

Quantitative anatomical comparison of transnasal and transcranial approaches to the clivus.
[BACKGROUND AND OBJECTIVE] The clivus was defined as "no man's land" in the early 1990s, but since then, multiple approaches have been described to access it. This study is aimed at quantitatively comparing endoscopic transnasal and microsu…

Circulating endothelial progenitor cells, microvascular density and fibrosis in obesity before and after bariatric surgery.
It is not known whether, in obesity, the capillary density or the number of circulating endothelial progenitor cells (EPCs) are reduced, or whether fibrosis of small vessels is also present. In addition, possible effects of weight reduction…
