Correction: An anatomical study of the subarachnoid space surrounding the trigeminal ganglion in horses-in preparation for a controlled glycerol rhizotomy in equids.

Summary

# Editorial Summary Controlled glycerol rhizotomy represents a promising intervention for trigeminal-mediated pain conditions in horses, yet its safe application requires precise anatomical knowledge of the structures surrounding the trigeminal ganglion and its subarachnoid space. Becker and colleagues undertook detailed anatomical dissection and imaging of equine trigeminal anatomy to establish the spatial relationships and dimensions critical for procedural planning, providing practitioners with evidence-based guidance on critical anatomical landmarks and the safe injection parameters necessary to target the ganglion whilst avoiding adjacent neurovascular structures. Their anatomical findings establish a foundation for standardising this minimally invasive technique and reducing procedural complications, which is particularly relevant given the growing recognition of trigeminal neuralgia and neuropathic pain conditions affecting the equine head and face. For farriers and veterinary surgeons managing horses with chronic headshaking, idiopathic facial pain, or post-traumatic trigeminal dysfunction, this work offers the anatomical rationale supporting controlled glycerol rhizotomy as a viable therapeutic option where conventional management has failed. The correction notation suggests refinements to the original 2024 publication, making this the definitive reference for practitioners considering this technique in clinical practice.
