Abstract

Backgound: The positioning of the reconstructed ear in ear reconstruction is a crucial step that directly affects the surgical outcome.This study employs the residual ear tissue as a reference, in conjunction with three-dimensional(3D)printing model of the normal ear's mirror image corresponding to the microtia ear, to facilitate precise positioning during the reconstruction of the ear.

Methods: This study established a 3D model group and a control group. The 3D model group utilized 3D printed models of residual ear tissue alongside the mirror image of the normal ear for positioning, while the control group relied on the surgeon's subjective observation.The symmetry of the reconstructed ear post-operation was evaluated by two independent physicians who were not involved in the surgical procedure for the patients.The patient was asked to use the Visual Analog Scale (VAS) to assess their satisfaction with ear symmetry and ear shape preoperative and postoperative 12 months.

Results: A total of 84 patients who met the inclusion criteria were enrolled in this study.In the 3D model group, no statistically significant differences were observed between the average distances from the highest and lowest points of the normal ear to the nasal axis and those of the reconstructed ear(P=0.688, P=0.916). Conversely, a statistically significant difference was noted in the control group (P=0.041; P=0.028).The 3D model group exhibited higher total scores on the VAS for patients' objective satisfaction CONCLUSION: The reconstructed ear can be accurately positioned by utilizing the residual ear tissue as a reference and employing 3D printing model with mirror technology.

小耳廓重建中重建耳廓的三维打印定位技术。

背景：耳部再造术中重建耳的定位是直接影响手术效果的关键步骤。本研究以残余耳组织为参照，结合正常耳与小耳对应的镜像三维（3D）打印模型，方便耳重建过程中的精确定位。方法：建立三维模型组和对照组。3D模型组利用3D打印的耳残组织模型和正常耳的镜像进行定位，而对照组则依靠外科医生的主观观察。术后重建耳的对称性由两名独立的医生评估，他们没有参与患者的手术过程。采用视觉模拟量表（VAS）评估患者术前和术后12个月对耳廓对称性和耳形的满意度。结果：84例符合纳入标准的患者被纳入本研究。3D模型组正常耳最高点、最低点至鼻轴的平均距离与重建耳最高点、最低点至鼻轴的平均距离差异无统计学意义（P=0.688， P=0.916）。相反，对照组差异有统计学意义(P=0.041；P = 0.028)。结论：以残耳组织为参照，采用3D打印模型结合镜像技术，可以准确定位重建耳。
