Abstract

Midline partial maxillectomy involving anterior nasal spine and septum in patients with maxillary carcinoma can result in postoperative depression of the nasal column and apex, even when a maxillary prosthesis is used. We encountered patients who developed significant nasal column and tip depression following surgery. To address this issue, we performed nasal septum reconstruction using auricular cartilage. Auricular cartilage was harvested bilaterally, and two grafts were stacked and transplanted into the nasal septal defect. After surgery, the transplanted cartilage became covered with mucosa, and the nasal column and apex were maintained without any signs of depression. This reconstruction technique represents a useful method for preventing nasal deformity in patients undergoing midline partial maxillectomy.

上颌中线部分切除术后用耳廓软骨重建鼻尖防止凹陷：附2例报告。

上颌癌患者的上颌中线部分切除术累及鼻前棘和鼻中隔，即使使用上颌假体，术后也会导致鼻柱和鼻尖凹陷。我们遇到的患者在手术后出现明显的鼻梁和鼻尖凹陷。为了解决这个问题，我们使用耳软骨进行鼻中隔重建。双侧摘取耳廓软骨，将2块移植物堆叠，移植到鼻中隔缺损处。术后移植软骨被黏膜覆盖，鼻柱和鼻尖保持良好，无凹陷迹象。这种重建技术是预防上颌中线部分切除术患者鼻畸形的有效方法。
