Presurgical correction of severe nasal deformities before cheiloplasty is often recommended for infants with cleft lip and palate. This article describes an approach for the computer-aided design and fabrication of a nasal molding stent. A 3-dimensional photogrammetric system was used to obtain the shape information of the nosewing that was then built as the nostril support for the nasal molding stent. The stent was fabricated automatically with a rapid prototyping machine. This technique may be an alternative approach to presurgical nasal molding in the clinic. Moreover, the patient's nasal morphology can be saved as clinical data for future study.
唇腭裂婴儿在唇裂修复术前，通常建议对严重鼻畸形进行术前矫正。本文描述了一种鼻成型支架的计算机辅助设计与制造方法。使用三维摄影测量系统获取鼻翼的形状信息，然后将其构建为鼻成型支架的鼻孔支撑。该支架由快速成型机自动制造。这项技术可能是临床上术前鼻成型的一种替代方法。此外，患者的鼻形态可以作为临床数据保存以供未来研究。
