Abnormal electromyographical trigeminal activation through stimulation of the offending artery (Z-L response): An intraoperative tool during microvascular decompression for trigeminal neuralgia.
Cephalalgia
November 2024
Department of Neuroscience, Catholic University School of Medicine, Rome, Italy.
Background: There are currently no intraoperative neurophysiological tools to assess the effectiveness of trigeminal nerve decompression during microvascular decompression surgery for drug-resistant trigeminal neuralgia. In microvascular decompression surgery for hemifacial spasm, an abnormal electromyographic activation of facial muscles after stimulation of the offending vessel was identified and named 'Z-L response'.
Methods: We adapted a neurophysiological protocol to elicit a Z-L response during microvascular decompression surgery for trigeminal neuralgia and applied it to a prospective series of 18 surgical patients.
A machine learning approach for age prediction based on trigeminal landmarks.

Department of Orthodontics and Dentofacial Orthopedics, Faculty of Dental Medicine- Lebanese University, Beirut, Lebanon. Electronic address:
Objective: The aim of this study was to estimate the chronological age (CA) of a growing individual using a new machine learning approach on Cone Beam Computed Tomography (CBCT).
Materials And Methods: The dataset included 48 CBCT and hand-wrist radiographs of growing individuals. 12 landmarks related to trigeminal trajectories were plotted on each CBCT and principal component analysis was applied for dimensionality reduction.
Successful true cavity pathfinding with balloon assisted CTO with bifurcation lesions: Two case reports.
Medicine (Baltimore)
March 2024
Department of Cardiology, Cardiovascular and Cerebrovascular Disease Hospital of General Hospital of Ningxia Medical University, Yinchuan, Ningxia, China.
Background: Coronary artery disease is a prevalent global cardiovascular ailment, with percutaneous coronary intervention (PCI) standing out as a crucial method for relieving symptoms and enhancing the quality of life in patients with coronary heart disease. However, the presence of concurrent chronic total occlusion (CTO) and bifurcation lesions within coronary arteries elevates the complexity and treatment risks, especially when the entry point of the CTO is ambiguous.
Objective: This study aims to present an innovative approach for treating CTO complicated with bifurcation lesions, focusing on true cavity pathfinding assisted by a balloon.
Hypothalamic Paraventricular Stimulation Inhibits Nociceptive Wide Dynamic Range Trigeminocervical Complex Cells via Oxytocinergic Transmission.

Oxytocinergic transmission blocks nociception at the peripheral, spinal, and supraspinal levels through the oxytocin receptor (OTR). Indeed, a neuronal pathway from the hypothalamic paraventricular nucleus (PVN) to the spinal cord and trigeminal nucleus caudalis (Sp5c) has been described. Hence, although the trigeminocervical complex (TCC), an anatomical area spanning the Sp5c, C1, and C2 regions, plays a role in some pain disorders associated with craniofacial structures (e.

Curr Med Imaging
February 2024
Department of Pediatrics, Liaocheng People's Hospital and Liaocheng Clinical School of Shandong First Medical University, Liaocheng, Shandong Province 252000, China.
Background: Persistent trigeminal artery (PTA) is the most common vascular anastomosis between the carotid artery and vertebrobasilar systems. We report a very rare case of dissecting aneurysm in the right internal carotid artery (ICA) with ipsilateral PTA and discuss its clinical importance.
Case Report: A 38-year-old male presented to the emergency department with paroxysmal dysphasia for 6h.
