Acquired Oronasal Fistula in a Domestic Ferret (Mustela Putorius Furo)

Acquired oronasal fistula is a rare cause of chronic nasal disease in ferrets (Mustela putorius furo) and other species. An adult male ferret presented with an acute unilateral swelling on the head and a 1-year history of sneezing. Physical examination and diagnostic procedures revealed an oronasal fistula of dental origin with concurrent abscess formation. Treatment included drainage of the abscess, treatment of the infection, extraction of the teeth involved in the oronasal fistula, debriding of the fistula edges, and placement of a medicated gauze. To the authors’ knowledge, this is the first report of an acquired oronasal fistula in a domestic ferret.
