背景与目的：利用肌皮瓣切开或闭合眼面缺损主要取决于颌面外科手术的考虑。对于那些出现闭合缺陷的病例，作者旨在评估一种使用磁共振成像数据集的眼球定位的创新方法。技术：在癌症切除和整形重建手术后，使用医学数字成像和通信格式磁共振成像数据集来确定左眼球的体积和位置。假体球的确切位置是通过镜像患处的位置来确定的。采用计算机辅助设计/计算机辅助制造（CAD/CAM）技术，将眼镜的图像导入虚拟环境，并投影子结构和面部假体的设计。讨论：本文提出的更新方法可以使用面部假体进行修复，即使使用肌皮瓣关闭缺损，从而解决了眼球定位问题，并且可以快速轻松地设计与眼镜相连的保留系统。该方案旨在开发和描述一种可行的方法来构建面部假体，用于使用肌皮游离皮瓣重建面部的患者。
Background and aim: Leaving open or closing the oculo-facial defect by means of a myocutaneous flap mainly depends on maxillofacial surgical considerations. For those cases that present a closed defect, the authors aim to evaluate an innovative method of ocular bulb positioning using a magnetic resonance imaging dataset.Technique: Following cancer removal and plastic reconstructive surgery, a Digital Imaging and Communications in Medicine format magnetic resonance imaging dataset was used to determine the volume and position of the left ocular bulb. The exact location of the prosthetic bulb was determined by mirroring this position on the affected side. Images of the eyeglasses were imported into the virtual environment, and the designs of the substructure and facial prosthesis were projected using computer-aided design/computer-aided manufacture (CAD/CAM) technology.Discussion: The updated method presented here enables restoration with a facial prosthesis, even when a myocutaneous flap is used to close the defect, thereby resolving the problem of ocular bulb positioning and enabling the rapid and easy design of a retention system connected to eyeglasses.Clinical relevance The proposed protocol aims to develop and describe a viable method for the construction of a facial prosthesis for a patient whose face had been reconstructed using a myocutaneous free flap.
