A Single Caudally Based Frontonasal Bone Flap for Treatment of Bilateral Mucocele in the Paranasal Sinuses of an American Miniature Horse

Abstract

To describe successful surgical treatment of bilateral mucocele in an American Miniature horse using a single bone flap to approach right and left paranasal sinuses simultaneously. Clinical report. A castrated 6-year-old American Miniature Horse with a bilateral mucocele of the paranasal sinuses. A single bilateral frontonasal sinus flap was used in a standing procedure to access the left and right conchofrontal sinuses simultaneously to remove the mucous contents and to establish permanent drainage into the nasal cavities. The novel procedure used in this horse allowed excellent access to right and left paranasal sinuses simultaneously and completely resolved nasal discharge and difficulty breathing. A single, bilateral frontonasal sinus flap can be used successfully as a standing procedure to treat bilateral sinonasal disease in horses.
