Abstract
BackgroundSilicone-based facial prostheses have traditionally been considered difficult to make and require time-consuming fabrication due to their basic liquid characteristics.Methods and resultsA detailed procedure for creating an ideal silicone orbital prosthesis was developed, including dental implant-supported retention, three-dimensional (3D) orbital scanning with symmetric volume and size measurement based on matching the opposite side, master mold fabrication for convenient pouring of the liquid silicone elastomer, and easy and comfortable management of the prosthesis by the patient.ConclusionA silicone orbital prosthesis could be more easily and conveniently produced using updated surgical skills and modern 3D technology. The combination of 3D scanning with digital reconstruction and an innovative fabrication protocol using a reproducible major mold and multiple prototypes fitting resulted in an accuracy personalized facial prosthesis with accessible cost and short production period.

A metal plate was placed in the right frontal sinus area, and the patient was scheduled for a routine magnetic resonance imaging (MRI) appointment every 4 months during the first year postoperatively
Summary
Silicone-based facial prostheses have traditionally been considered difficult to make and require timeconsuming fabrication due to their basic liquid characteristics. The procedure was the combination of 3D facial scanning, digital reconstruction, and innovation of traditional silicone prosthesis production using the reproducible major mold and multiple prototypes. This is a promising protocol in the personalized fabrication of silicone facial prosthesis for diverse facial defect cases. A 71-year-old woman who had been diagnosed with squamous cell carcinoma of the right frontal sinus was referred to our facility for orbital reconstruction She had undergone craniofacial fronto-ethmoidectomy with eyeball exenteration by a neurosurgeon and otorhinolaryngologist 16 months previously and had received induction chemotherapy with docetaxel and cisplatin and a course of postoperative radiation therapy at a total dosage of 6300 cGy in 28 fractions 14 months previously.
