On physicalexamination, the dogs showed difficulty breathing and open-mouth breathing and large masses were found on the hardpalate and soft palate. Cardiac arrest happened in case 2 and the dog was stabilized with cardiopulmonary resuscitationand oxygen therapy. Computed tomography demonstrated that the mass occupied the oropharynx, intrapharyngealostium, and laryngopharynx including the hard palate and soft palate in case 1. Palliative surgery was decided to improveswallowing and breathing with owner’s consent in two dogs. Buccal mucosal flaps were performed for reconstructionof defects using rotational and single-pedicle advancement flaps and bilateral 90 degree transposition flaps in cases1 and 2, respectively. Histopathology results described the oral masses as amelanotic melanoma in two dogs. Theowners reported that there was normal swallowing and breathing at 7 days postoperatively in two dogs.
