title: Radiographic appearance of maxillary sinus feed impaction in a horse.
abstract: A 15-year-old Belgian gelding presented in respiratory distress, with bilateral mucopurulent nasal discharge, and right-sided epistaxis. The horse had a 5-year history of dental disease and had been recently losing weight. Radiographs indicated tooth root abscessation of the right maxillary third molar tooth and probable maxillary sinus feed impaction. These findings were confirmed at surgery and necropsy. The stippled, granular radiographic appearance described here is highly characteristic of sinus feed impaction.
