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.
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.
描述了两只犬使用基于口角动静脉的颊黏膜瓣修复硬腭缺损手术重建相关的并发症。两例均发生远端皮瓣坏死，但通过切断原皮瓣蒂并将皮瓣材料旋转至剩余缺损处，成功挽救了皮瓣。两只犬在皮瓣修复前均观察到术后吞咽困难。讨论了术后14天切断直接动静脉后挽救皮瓣完整远端部分的情况。
口角轴型颊瓣是修复硬腭大缺损的一种选择。通过拔除可能对口瓣蒂造成咬合创伤的牙齿，可提高皮瓣存活率。若发生远端皮瓣坏死，在建立来自相邻组织的血供后，可通过将剩余皮瓣旋转至缺损处挽救修复。
