CorrespondenceSurgical Freedom: A Challenging Topic in Endoscopic Endonasal Approaches
Section snippets
Letter:
We read with the great interest the article by Little et al., “Endoscopic Endonasal Transmaxillary Approach and Endoscopic Sublabial Transmaxillary Approach: Surgical Decision-Making and Implications of the Nasolacrimal Duct (3),” concerning the endoscopic transmaxillary approaches to the lateral skull base. We sincerely appreciate the efforts of these authors in analyzing “the nasolacrimal duct on preoperative axial imaging and drawing a line from the anterior nasal septum to the tumor through

The (R)evolution of Anatomy
2019, World NeurosurgeryCitation Excerpt :In theory, the optimal surgical exposure is a function of target location, anatomy, and surgical pathways. The quantitative perspective creates an algorithm within the reconstructed model that solves this complex problem to optimize visualization and the ability to perform surgical tasks within the target location.92-95 Although the question of how far it was possible to see through the endonasal endoscopic route was on the way to be answered, we believed another interrogative needed to be solved; that is, how far was it safe to work.
Surgical Freedom Evaluation During Optic Nerve Decompression: Laboratory Investigation
2017, World NeurosurgeryCitation Excerpt :Osirix MD software (OsiriX [Osirix Foundation, Geneva, Switzerland]) was used to quantitatively analyze the degree of bony optic canal decompression. Then, the surgical freedom was calculated as described by de Notaris and Prats-Galino23 and Dallan et al.26 using the midpoint of the intracanalicular optic nerve as the base for the stereotactic pointer. For each approach, points for calculating surgical freedom were acquired as follows: p1, the point of maximal cranial extension in the direction of the nasion; p2, the point of maximal caudal extension in the cephalad direction to the vertex; p3, the point of maximal lateral extension toward the external acoustic meatus; and p4, the point of maximal medial extension toward the nasal septum.
