Preoperative exposure of sigmoid sinus trajectory in posterolateral cranial base approaches using a new landmark through a neurosurgical perspective

For venous anatomy preservation and anatomic skullbase fossa orientation during posterolateral cranial base approaches, upward extension of the mandibula-mastoid line can be a proper landmark for surgical planning in this region. The authors’ proposed superficial anatomical line and intersection point over the skull could be used as a reliable indicator for the external projection of the sigmoid sinus and an appropriate initial burr-hole location.

Low-Cost Stereoscopic Recordings of Neurological Surgery Operative Microscopy for Anatomical Laboratory Training

Stereoscopic video recordings of operative microscopy during neuroanatomic dissections are an important component of surgical training and research in well-financed medical schools and teaching hospitals. However, the high cost of the latest operative microscopes with integrated video recording equipment can be a limiting factor in their worldwide use. The aim of the present work is to provide a simple low-cost 3-dimensional (3D) stereoscopic operative microscope recording system that can be used even in economically and resource-limited locations. This is achieved by using readily available smartphones, smartphone accessories, and computer software.

Is a Unilateral Surgical Approach Effective in Patients with Bilateral Leg Pain with Unilateral Lumbar Disc Herniation? A Prospective Nonrandomized Clinical and Surgical Study.

The goal of this study is to examine the surgical results of unilateral lumbar discectomy in patients with bilateral leg pain and discuss short- and long-term outcomes within the limits of lumbar decompression. As a result, conventional lumbar disc surgery alone is sufficient for the ipsilateral side of radiologically demonstrated disc herniation in patients with bilateral leg pain.

Lateral transorbital approach: an alternative microsurgical route for supratentorial cerebral aneurysms

Lateral transorbital approach: an alternative microsurgical route for supratentorial cerebral aneurysms: Transorbital approaches for neurosurgery have recently attracted attention and several anatomical studies have aimed to improve these techniques, but significant deficiencies in clinical practice remain, especially for aneurysm surgery. The authors present an alternative microsurgical route and the results of an analysis of patients with intracranial aneurysms who underwent a lateral transorbital approach (LTOA) using lateral orbito-zygoma-sphenotomy (LOZYGS).
