Oronasal fistula

Canine ONF

Feline ONF

A communication between the oral cavity and the nasal cavity or respiratory tract may be present in any species and adjacent to any tooth. The most common fistula, which be present prior to extraction due to advanced periodontal disease, or occur during extraction, is at the level of the maxillary canine tooth. This is a common site in the Dachshund breed dog. It is not uncommon to observe epistaxis from the side of the fistula during extraction. The goal of treatment is to repair the fistula using sound surgical technique: ensuring there is no tension on the flap, harvesting a large vascular flap, taking large bites of tissue when suturing, confirming knots are secure, not suturing over a void. Either a single or double flap technique may be employed.
