Jo Ann Hopkins and her 12-year-old Appendix-bred gelding, Blazer, were placed third in points in their local 1D barrel racing circuit. However, three months earlier, Blazer underwent surgery at Palm Beach Equine Clinic for a growing cyst in his sinus. On August 1, 2015, Dr. Weston Davis, DACVS, performed the surgical procedure on Blazer for an expansile paranasal sinus cyst of the left paranasal sinuses, extending to the right concho-frontal sinus.
Hopkins noticed that Blazer, who she calls “George” for his laid-back attitude, had a raised knot on his head this spring and consulted with her local vet, Dr. Kelly Alderman. The area was monitored closely and remained in a similar condition until June, when Hopkins noticed Blazer wheezing while running barrels and the knot increasing in size.
Diagnosing the Paranasal Sinus Cyst
Dr. Alderman performed radiographs on the site and aspirated the swelling where a substantial amount of fluid was removed. She confirmed that the bump was a suspected paranasal sinus cyst. At that point, Blazer was referred to Dr. Weston Davis of Palm Beach Equine Clinic, who advised Hopkins that the cyst was likely growing slowly within the sinus for a considerable amount of time with no clinical signs. The diagnosis was an expansile paranasal sinus cyst of the left paranasal sinuses, extending to the right frontal sinus.
Paranasal Sinus Cyst Surgery
For surgery, Blazer was placed under standing sedation and local analgesia (painkiller) and his head was aseptically prepared before Dr. Davis performed a frontonasal sinusotomy (incision into the sinus). He made an opening from the middle of Blazer’s head to the corner of his eye. Once the skin flap was elevated and the bone fractured, a large amount of fluid was evacuated, which is consistent with the contents of a paranasal sinus cyst. Dr. Davis also observed that the sinus cavity was extremely distorted and expanded. The cyst lining was debrided and removed, then the sinus was lavaged and a tube was advanced into the sinus cavity to facilitate drainage. The sinus was packed with gauze tied together and soaked in a dilute betadine. Finally, the bone flap was replaced and the skin was closed and covered with a sterile bandage.
The gauze packing was removed 48 hours after surgery and upon release from Palm Beach Equine Clinic, Hopkins was instructed to monitor the incision for heat, swelling and discharge. Bute, in the amount of 2g, was administered orally once a day for five days and Dr. Alderman removed the sutures after 10 days.
Hopkins characterizes Blazer as a sweet gelding with heart to spare, and is happy to report that his recovery has been fantastic. After six weeks of stall rest and rehab time to get back in shape, Blazer recently won his first barrel race after surgery. According to Hopkins, Blazer is running better than ever thanks to Dr. Davis and the staff at Palm Beach Equine Clinic.
