Abstract
Summary: This case report describes the diagnosis and removal of a metallic foreign body embedded within the left nasopharyngeal wall of a symptomatic pony. The object was initially detected with radiographic imaging, with more detailed information regarding the location obtained using standing computed tomography (CT). A transnasal, laser‐assisted endoscopic removal of the object was successfully performed as a standing procedure, and the pony was discharged 24 h postoperatively. Follow‐up endoscopic examination performed at 4 weeks revealed good healing of the surgical site, with a small focal area of raised granulation tissue present. Repeat endoscopic examination at 10 weeks revealed resolution of the granulation tissue and complete healing of the surgical site. The pony had already returned to normal management and exercise. In summary, this case report highlights the benefits of standing CT evaluation in pre‐surgical planning of foreign body removal involving the head and upper cervical region. The surgical technique adopted in this report may assist similar procedures where traditional approaches are limited.
