Master of Science / Strangles is an extremely infectious disease of horses that has negative financial and health consequences. After infection, some horses form balls of concrete-like pus in a structure in an air-filled sac of the ear canal called guttural pouches (GPs). These concretions, called chondroids, allow affected horses to continue to pass on infection to other horses. Removal of chondroids is needed to stop disease transmission but current non-surgical and surgical removal techniques have limitations. Surgical laser passed through an endoscope (medical camera) allows minimally invasive surgery of the guttural pouches. We performed laser surgery on cadaver horse heads to create access to the GP, then evaluated our ability to remove chondroid-like beads from the GP using a custom-made 3D-printed instrument. Our results showed efficient and complete removal of the beads compared to lavage without the 3D-printed instrument, with little damage to the heads. These findings are an initial step to development of a new chondroid-removal technique and may allow surgeons to more efficiently remove chondroids without the need for invasive surgery.
