Seven oronasal fistula lesions secondary to extraction of maxillary canine teeth were treated in 5 dogs using a cartilage graft harvested from the ipsilateral auricular pinna. All dogs had undergone previous, unsuccessful surgeries in attempt to repair the defects. The technique is described in a step-by-step fashion for easy reproduction. The authors found the technique to be straightforward, relatively quick, and successful in all 7 lesions.
