Localization of Maxillary Artery for Cerebral Revascularization: L-Shaped Perpendicular Two-Step Drilling Technique Stretching from the Foramen Ovale to Rotundum.

Background: The use of the maxillary artery (MA) as a donor has increasingly become an alternative method for cerebral revascularization. Localization difficulties emerge due to rich infratemporal anatomical variations and the complicated relationships of the MA with neuromuscular structures. We propose an alternative localization method via the interforaminal route along the middle fossa floor.

Tissue Expressions of Regulatory Enzymes of the Krebs Cycle in Low- and High-grade Gliomas.

Aim: To compare tissue levels of the regulatory enzymes related to the Krebs cycle between low, and high-grade supratentorial gliomas.

Material And Methods: Forty patients who underwent surgery for supratentorial gliomas (19 with low-grade and 21 with high-grade gliomas) were evaluated. The regulatory enzymes directly involved in the Krebs cycle, namely pyruvate dehydrogenase, citrate synthase, ?-ketoglutarate dehydrogenase, and isocitrate dehydrogenase, and two enzymes that indirectly regulate the Krebs cycle, namely glutamate dehydrogenase and glutaminase, were quantitatively studied in tumor tissues using ELISA.

Endoscopic Endonasal Optic Nerve Decompression in Idiopathic Intracranial Hypertension: When to Implement Optic Nerve Sheath Fenestration.

Background And Objective: Idiopathic intracranial hypertension (IIH) is a syndrome characterized with increased intracranial pressure and normal cerebrospinal fluid (CSF) composition. Treatment is mainly conservative, whereas CSF diversion surgery is the most frequently used surgical intervention. Endoscopic endonasal optic nerve decompression (EOND) is a newer surgical treatment of this patient group.

Factors Affecting Seizure Outcomes After Surgery for Cavernoma Related Epilepsy.

Aim: To present one of the largest retrospective cavernoma related epilepsy (CRE) studies which include divergent supratentorial locations operated and followed up at least 2 years. We also investigated the factors affecting the seizure outcome.

Material And Methods: This study includes a total of 56 patients with drug-responsive (n=40) and drug-resistant (n=16) CRE who underwent resective surgery.

Evaluation of Ideal Extent of Corpus Callosotomy Based on the Location of Intracallosal Motor Fibers.

Background: The corpus callosotomy (CCT) has been reported as an effective procedure to alleviate drop attacks. However, the extent of CCT remains debatable. Classical studies suggest that motor fibers traverse mainly through the anterior half of the corpus callosum (CC), although recent diffusion tensor imaging studies described that motor fibers crossed the CC in a more posterior location, emphasizing the posterior midbody and the isthmus.

Zucker diabetic fatty rat: a new model of impaired cutaneous wound repair with type II diabetes mellitus and obesity.

Impaired diabetic wound healing is an important current medical issue, mainly concerning patients recovering from complicated operations or patients with ulcers on their feet. The obese Zucker diabetic fatty rat, with a mutation in leptin receptors, may be a good choice for studying impaired wound healing. Male and female rats were fed a diabetogenic high-fat diet.
