Surgical vaginoplasty is a highly successful treatment for congenital absence of the vagina. One key to long-term success is the use of an appropriate vaginal mold in the immediate postoperative period. We present the use of a three-dimensional (3D)-printed vaginal mold, customizable to the anatomy of individual patients.
Vaginal molds were designed using a 3D modeling software program. The design included narrowing around the urethra, holes for egress of secretions, and a knob for insertion and removal. Dental resin was 3D-printed into various-sized vaginal molds, and postprocessing was performed.
We present the use of the 3D-printed mold for a patient with a history of cloacal exstrophy and a unique pelvic shape. Two prior neovagina surgeries in this patient had been unsuccessful due to ineffective handheld dilator use; the patient experienced success with the 3D-printed intravaginal mold.
The use of the 3D-printed vaginal mold is an alternative to the limited commercially available models today and allows for customization to user anatomy. With 3D printers becoming more widely accessible, we believe this method could become universally accepted, with hopes of contributing to increased patient satisfaction and decreased complications.
外科阴道成形术是治疗先天性阴道缺失的一种非常成功的方法。长期成功的关键之一是在术后立即使用合适的阴道模具。我们介绍了一种可定制为个体患者解剖结构的三维（3D）打印阴道模具的使用。
使用 3D 建模软件程序设计阴道模具。设计包括围绕尿道变窄、分泌物出口孔和用于插入和取出的旋钮。牙用树脂被 3D 打印成各种尺寸的阴道模具，并进行后处理。
我们介绍了在一名患有先天性泄殖腔外翻和独特骨盆形状的患者中使用 3D 打印模具的情况。该患者此前进行了两次新阴道手术，但由于手持式扩张器使用效果不佳而失败；该患者成功使用了 3D 打印阴道内模具。
使用 3D 打印阴道模具是目前有限的商业可用模型的替代方法，并且可以根据用户解剖结构进行定制。随着 3D 打印机的普及，我们相信这种方法可能会被普遍接受，希望能提高患者满意度并减少并发症。
