Use of Magnetic Resonance Neurography for Sensory Nerve Injuries of the Head and Neck.
Plast Reconstr Surg Glob Open
January 2025
From the Department of Plastic and Reconstructive Surgery, Weill Cornell Medicine, New York, NY.
Background: Identification of peripheral nerve injuries of the head and neck can be challenging due to a broad spectrum of symptoms from neuropathic pain to headaches and migraine. This article aimed to present the clinical features and diagnostic workup of patients with acute and chronic peripheral nerve injuries of the head and neck using magnetic resonance neurography (MRN), to demonstrate potential advantages compared with conventional magnetic resonance imaging (MRI).
Methods: Patients who presented with suspected peripheral nerve injury were either referred for a conventional MRI or MRN.

Axonal fusion represents an efficient way to recover function after nerve injury. However, how axonal fusion is induced and regulated remains largely unknown. We discover that ferroptosis signaling can promote axonal fusion and functional recovery in C.

Background: Following transection, nerve repair using the polylactic acid (PLA) conduit is an effective option. In addition, inosine treatment has shown potential to promote nerve regeneration. Therefore, this study aimed to investigate the regenerative potential of inosine after nerve transection and polylactic acid conduit repair.

Wallerian degeneration (WD) was first discovered by Augustus Waller in 1850 in a transection of the glossopharyngeal and hypoglossal nerves in frogs. Initial studies suggested that the formation mechanism of WD is related to the nutrition of neuronal cell bodies to axons. However, with the wide application of transgenic mice in experiments, the latest studies have found that the mechanism of WD is related to axonal degeneration, myelin clearance and extracellular matrix.

Background: Loss of key-pinch sensation after median nerve injury poses significant functional detriment. Nerve transfers are utilized to improve function after nerve injury and size matching of donor and recipient nerves is important to optimize success. This anthropometric study investigates the anatomy of the superficial branch of the radial nerve (SBRN) to the thumb and index finger and explores radial to median sensory nerve transfers, a necessary but not heavily discussed facet of nerve transfers for the hand.
