Abnormal Passageway Between the Mouth and Nasal Cavity in Dogs




Surgical removal of the tooth, and closure of the passageway is the treatment of choice. A skin flap will be placed in both the mouth and in the nasal cavity during closure.


Living and Management


Since a flap to repair an oronasal fistula undergoes constant tension each time the dog breathes, oronasal fistulae tend to reopen. Additional surgeries with advanced tissue flaps can be performed if this occurs.
