Medial Pontine Area: A Safe Entry to the Brainstem as a Cut Above the Rest.

Aim: To examine the fiber-based anatomy of the medial pontine area (MPA), one of the most commonly used brainstem (BS) safe entry zones in neurosurgery.

Material And Methods: According to the protocol of Klingler and Ludwig, six BSs were kept in 10% formalin solution for at least 2 months. After removing the arachnoid mater, pia mater, and vascular structures, the samples were frozen at -16°C for at least 2 weeks.

Classification of Osteophytes Occurring in the Lumbar Intervertebral Foramen.

Background: Surgeons have limited knowledge of the lumbar intervertebral foramina. This study aimed to classify osteophytes in the lumbar intervertebral foramen and to determine their pathoanatomical characteristics, discuss their potential biomechanical effects, and contribute to developing surgical methods.

Methods: We conducted a retrospective, non-randomized, single-center study involving 1224 patients.

Improving the Visualization of Superior Longitudinal Fascicule-2 and Superior Longitudinal Fascicule -3 Using Photoshop Filters.

Background And Objectives: Several studies are currently exploring the anatomical origins of superior longitudinal fascicule (SLF) 2 and SLF-3, which are components of the frontoparietal network. This study aimed to achieve optimum visualization of the anatomical corridors of these fibers using Photoshop filters.

Methods: Four postmortem brain hemispheres were dissected in accordance with the method proposed by Klingler and Ludwig.

Dentate Nucleus: Connectivity-Based Anatomic Parcellation Based on Superior Cerebellar Peduncle Projections.

Objective: Projections from the dentate nucleus (DN) follow a certain organized course to upper levels. Crossing and noncrossing fibers of the dentatorubrothalamic (DRT) tract terminate in the red nucleus and thalamus and have various connections throughout the cerebral cortex. We aimed to establish the microsurgical anatomy of the DN in relation to its efferent connections to complement the increased recognition of its surgical importance and also to provide an insight into the network-associated symptoms related to lesions and microsurgery in and around the region.

Surgical outcomes of decompressive laminectomy by transspinous approach for degenerative lumbar spinal stenosis.

Objective: To assess clinical and radiographical outcomes of transspinous decompression technique for the treatment of degenerative central lumbar spinal stenosis.

Methods: The single-centre, non-randomised interventional, prospective, observational study was conducted Neurosurgery Clinic of Mazhar Osman Research and Training Hospital for Psychiatry and Neurology, Istanbul, Turkey from May 2013 and May 2016 and comprised adult patients with refractory symptoms from degenerative central lumbar spinal stenosis who underwent lumbar spinous processsplitting laminectomy. Pre- and post-operative Oswestry Disability Index score, visual analogue scale for overall pain, maximum walking distance and anteroposterior diameter of the spinal canal on magnetic resonance imaging were assessed on follow up examination.
