A long‐term study of 277 cases of equine sinonasal disease. Part 2: Treatments and results of treatments

Abstract

Summary The treatments of 277 horses with equine sinonasal disease (1984–1996), described by Tremaine and Dixon (2001), are reported here. Long‐term (median duration 24 months) outcomes of treatment of the more common disorders were good, with 92% of horses with sinonasal mycosis, 84% with primary sinusitis, 82% with sinus cysts, 78% with dental sinusitis and 75% with sinonasal trauma reported to have complete remission of clinical signs. However, only 33% of horses with progressive ethmoidal haematoma (PEH) and 12% with sinonasal neoplasia reported long term remission of clinical signs.
