Abstract

BACKGROUND

Successfully restoring facial contours continues to pose a significant challenge for surgeons. This study aims to utilize head-mounted display-based augmented reality (AR) navigation technology for facial soft tissue defect reconstruction and to evaluate its accuracy and effectiveness, exploring its feasibility in craniofacial surgery.

METHODS

Hololens 2 was utilized to construct the AR guidance system for facial fat grafting. Twenty artificial cases with facial soft tissue defects were randomly assigned to Group A and Group B, undergoing filling surgeries with the AR guidance system and conventional methods, respectively. All postoperative three-dimensional models were superimposed onto virtual plans to evaluate the accuracy of the system versus conventional filling methods. Additionally, procedure completion time was recorded to assess system efficiency relative to conventional methods.

RESULTS

The error in facial soft tissue defect reconstruction assisted by the system in Group A was 2.09 ± 0.56 mm, significantly lower than the 3.23 ± 1.15 mm observed with conventional methods in Group B (p < 0.05). Additionally, the time required for facial defect filling reconstruction using the system in Group A was 25.45 ± 2.58 min, markedly shorter than the 37.05 ± 3.34 min needed with conventional methods in Group B (p < 0.05).

CONCLUSION

The visual navigation offered by the fat grafting AR guidance system presents obvious advantages in facial soft tissue defect reconstruction, facilitating enhanced precision and efficiency in these filling procedures.

摘要

背景

成功恢复面部轮廓仍然是外科医生面临的重大挑战。本研究旨在利用基于头戴式显示器的增强现实（AR）导航技术进行面部软组织缺损重建，并评估其准确性和有效性，探索其在颅面外科中的可行性。

方法

使用 Hololens 2 构建面部脂肪移植的 AR 引导系统。将 20 例具有面部软组织缺损的人工病例随机分为 A 组和 B 组，分别采用 AR 引导系统和传统方法进行填充手术。将所有术后三维模型叠加到虚拟计划上，以评估系统相对于传统填充方法的准确性。此外，还记录了手术完成时间，以评估系统相对于传统方法的效率。

结果

A 组中系统辅助的面部软组织缺损重建误差为 2.09±0.56mm，明显低于 B 组中传统方法的 3.23±1.15mm（p<0.05）。此外，A 组中使用系统进行面部缺陷填充重建所需的时间为 25.45±2.58min，明显短于 B 组中传统方法的 37.05±3.34min（p<0.05）。

结论

脂肪移植 AR 引导系统提供的视觉导航在面部软组织缺损重建中具有明显优势，有助于提高这些填充手术的精度和效率。
