Plain-English summary
This study looked at 277 horses with sinonasal disease, which affects the nasal passages and sinuses. The most common problems included primary sinusitis (inflammation of the sinuses), dental sinusitis (related to teeth), and sinus cysts. Many horses showed similar signs, such as nasal discharge and facial swelling, and most had been showing symptoms for a long time, averaging about 12 weeks before they were referred for help. While various tests like endoscopy and X-rays were performed, they were not always helpful in making a clear diagnosis. Overall, the study highlights the complexity of diagnosing sinonasal issues in horses, and treatment effectiveness varied depending on the specific condition.
Abstract
The clinical and ancillary diagnostic findings in equine sinnasal disease were studied. The diagnoses in 277 referred (1984-1996) cases of equine sinonasal disease included the following (% all cases): 67 cases (24.2%) primary sinusitis, 61 (22.0%) dental sinusitis, 37 (13.4%) sinus cysts, 22 (7.9%) sinonasal neoplasia, 21 (7.6%) progressive ethmoid haematoma, 17 (6.1%) sinonasal trauma, 13 (4.7%) sinonasal mycosis, 11 (4.0%) rostral maxillary cheek tooth infection, 7 (2.5%) sinonasal polyps, 7 (2.5%) cases of nasal epidermal inclusion cysts and 14 (5.1%) miscellaneous sinonasal disorders. Many disorders showed similar clinical signs including nasal discharge (present in 88% of all cases) and facial swelling (46%). Most disorders were chronic, with a median duration of signs of 12 weeks (range 3 days- 6 years) prior to referral. Sinus cysts and sinonasal neoplasia were significantly (P<0.05) more frequently associated with gross distortion of the nasal passages and facial bones than the other sinonasal disorders. Endoscopic changes were detected per nasum in 91% of cases, but contributed to the exact diagnosis in only 20%. Radiography revealed abnormalities in 81% of cases but was diagnostically useful in only 36%. Sinoscopy was diagnostically useful in 70% of the 61 cases where used.
