Case report Complications associated with surgical reconstruction of hard palate defects with a buccal mucosal flap based on the angularis oris artery and vein in two dogs are described. Distal flap necrosis occurred in both cases, but the flaps were successfully salvaged by division of the original flap pedicle and rotation of the flap material into the remaining defect. Postoperative dysphagia was observed in both dogs until flap revision. Salvage of the intact distal portion of the flap following division of the direct artery and vein 14 days postoperatively is discussed. Conclusion The angularis oris axial pattern buccal flap is an option for reconstruction of large defects of the hard palate. Survival of the flap can be improved by removal of teeth likely to cause occlusal trauma to the flap's pedicle. In the event of distal flap necrosis, the repair may be salvaged by rotation of the remaining flap into the defect, following establishment of vascular supply from adjacent tissue.
