A 9-year-old, male North African leopard (Panhtera pardus) presented with mandibular brachygnathism and lingually displaced mandibular canine teeth causing a large left oronasal fistula, rhinitis and nasal discharge, and a right orocutaneous fistula. Surgical closure of the left oronasal defect, bilateral mandibular canine tooth crown reduction, and root canal therapy resulted in a positive clinical outcome. A small recurrent left oronasal fistula and the right orocutaneous fistula healed spontaneously after alleviating the occlusal contact with the mandibular canine teeth. At 12-months postoperatively, clinical signs of oral and dental disease had resolved.

An acquired palatal defect in dogs is a pathologic condition in which there is communication between the oral cavity and nasal cavities, maxillary recesses, or orbits. Many different causes exist and must be considered. Two dogs were presented for severe palatal defects secondary to a foreign body trapped between maxillary dental arches. Numerous techniques have been previously described to repair palatal defects, and the most appropriate choice is based on the clinical features of the defect and information obtained from advanced diagnostic imaging. Acquired palatal defects are not predictable in shape, size, and location; therefore, although the literature contains many different surgical techniques, these are not always reliable. The aim of this article is to describe an innovative surgical approach to repair severe acquired caudal palatal defects in two different dogs.
