Plain-English summary

Cysts can form in the sinuses of horses, and while this is likely a condition they are born with, symptoms might not show up until years later. In four horses, signs appeared when fluid built up in the cysts, causing nasal discharge or swelling in the face, or when an infection developed. The treatment involved surgery to remove the cysts and any affected tissue. After surgery, the horses received care that included flushing the sinuses and antibiotics to prevent infection. The treatment was successful in addressing the issues caused by the cysts.

Abstract

Development of cysts in the equine paranasal sinuses is probably a congenital disease; however, signs may not appear for several years. In 4 cases, clinical signs were observed when fluid accumulation within the cysts resulted in nasal discharge or facial swelling, or when secondary infection occurred. Treatment required surgical removal of the lining membrane and other involved tissues. Postoperative care included lavage of the sinuses and systemic antibiotic therapy.
