Pre\u2010referral surgical treatments included maxillary cheek tooth extraction (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009234 teeth) in 201 horses (12.6%), sinoscopy (11.8%), nasofrontal sinus osteotomy (5.2%) and maxillary sinus osteotomy (3.6%). Nasal airflow was obstructed in 14.9%, and facial swelling was present in 26.9% of cases. Nasal endoscopy showed exudate at the sinonasal ostium in 65.8% of cases, and middle meatus abnormalities, including inspissated exudate, sequestra and sinonasal fistulae, were present in 44.6%. A multivariable model was built with data from 650 cases. Age at presentation greater than 12\u2009years (odds ratio [OR] 0.53, 95% confidence interval [CI] 0.36\u20130.79), sinonasal disease of over 8\u2009weeks duration (OR 0.63, 95% CI 0.42\u20130.94), nasofrontal sinusotomy prior to referral (OR 0.36, 95% CI 0.16\u20130.81) and presence of facial swelling or bilateral nasal discharge at presentation to a referral centre (OR 0.33, 95% CI
