To report the surgical technique and outcome of the use of a pinna composite flap for reconstruction of a wound defect following wide surgical resection of a mast cell tumor.
A 4-year-old female spayed golden doodle.
Clinical case report.
A dog with a histologically confirmed cutaneous mast-cell tumor at the base of the ear was treated with a wide surgical resection, including total ear canal ablation and lateral bulla osteotomy. The defect could not be closed primarily and, as a result, the defect was reconstructed with a composite pinna flap.
Partial avascular necrosis of the distal aspect of the composite flap required debridement and closure 13 days after the initial surgery. The flap was fully healed at 27 days postoperatively. The dog had facial nerve paralysis, which had not resolved by 45 weeks postoperatively.
The surgical technique described in this report is novel. The use of the pinna as a composite flap is a novel reconstructive option for dorsal and dorsolateral head wounds.
报告使用耳廓复合瓣修复犬耳郭基底大面积切除术后缺损的手术技术和结果。
一只 4 岁已绝育的雌性金贵狗。
临床病例报告。
一只患有组织学证实的皮肤肥大细胞瘤的犬接受了广泛的手术切除，包括全耳道消融和外侧鼓骨切开术。缺损无法直接一期闭合，因此使用复合耳廓瓣进行了重建。
术后 13 天，复合瓣远端部分出现血管性坏死，需要清创和闭合。术后 27 天，皮瓣完全愈合。术后 45 周时，患犬仍存在面神经瘫痪，未恢复。
本报告中描述的手术技术是新颖的。将耳廓用作复合瓣是一种用于头背部和背侧头部伤口的新型重建选择。
