Greater palatine island axial pattern flap for repair of oronasal fistula related to eosinophilic granuloma.

A Greyhound presented with eosinophilic granuloma lesions of the soft palate and oronasal fistula. Since other siblings had been known to also have oral eosinophilic granuloma, it was suspected that the dog reported here had a familial predisposition to develop the disease. Preoperative medical management consisting of anti-inflammatory and immunosuppressive therapy was required before surgical repair of the oronasal fistula. Multiple surgical techniques, including a greater palatine island axial pattern flap, were used to repair the oronasal fistula.
