Technique for guttural pouch bead removal using a novel three-dimensional (3D)-printed instrument. The aim of the present study was to determine if a three-dimensional (3D)-printed instrument technique would improve lavage removal of plastic beads (guttural pouch [GP] chondroid mimics) through a dorsal pharyngeal recess (DPR) fenestration. We hypothesized that using a 3D-printed instrument placed through the DPR fenestration would remove more beads, reduce lavage time and incur less soft tissue damage than using a lavage tube control or instrument placement through the salpingopharyngeal ostium (SPO). Methods: Experimental cadaveric study. Methods: A total of 30 cadaveric equine heads. Meth...
An Explorative Anatomical Study on Inter-Individual Variation of the Tibial Nerve and Landmarks for Perineural Anesthesia in Horses. Perineural anesthesia of the tibial nerve can be performed ultrasound-guided or blindly, with the latter still being commonly used in equine practice due to practical constraints, despite its lower accuracy and hence, common failure to achieve desensitization. This may be associated with anatomical variations or inadequate landmarks for injection. To examine the course of the tibial nerve, document potential anatomical variations, and determine optimal landmarks for perineural injection, dissection was conducted along the medial aspect of the tibia in 10 paired cadaver hindlimbs. No anatomical...
