Plain-English summary

Five horses were diagnosed with a type of sinus infection called primary paranasal sinusitis, which was made worse by thick, sticky fluid in a specific sinus. They showed signs like a bad-smelling, gooey discharge from one nostril that lasted between two to seven months, and two of the horses had some difficulty breathing through their nose due to swelling. X-rays of their skulls revealed a mass near their upper cheek teeth. The treatment involved a surgical procedure to open the sinus and remove the thick fluid. All five horses fully recovered from their sinus infections after the treatment.

Abstract

Primary paranasal sinusitis complicated by inspissated exudate within the ventral conchal sinus was diagnosed in five horses. Clinical signs included a unilateral, foul-smelling, mucopurulent nasal exudate of 2 to 7 months' duration. Two of the horses had partial nasal obstruction from distortion of the ventral concha. Radiographs of the skull showed a mass of soft tissue density dorsal to the roots of the superior third and fourth or fourth and fifth cheek teeth. Treatment included bone flap maxillary sinusotomy with exposure of the ventral nasal concha and removal of inspissated exudate. Resolution of the sinusitis occurred in all five horses.
