The objective of this study was to describe the manual fabrication of a transparent facial pressure mask for treating facial deformities. The mask combines the use of a silicone inner liner and mechanical pressure in the facial region.
A negative mold is formed by covering the face with plaster. Manipulation of soft tissue is a crucial part in this process. After hardening and removal of the negative mold, the positive mold is formed and dried. Next a rolled silicone sheet is placed over the positive mold in a vacuum environment. Subsequently, the silicones are vulcanized. Then the rigid outside of the mask is created. The silicone inner liner and outside shell are then affixed.
This described technique results in accurate facemasks with precise fitting. During therapy, the mask is adjusted multiple times to keep excellent fit, as remodeling of scars and deformities takes place.
Facemasks are a reputable therapeutic modality to reduce excessive facial scarring. They require excellent fitting to give pleasing results. To provide a better understanding of facemask therapy, this study describes the manual fabrication technique.
本研究的目的是描述一种用于治疗面部畸形的透明面部压力面罩的手工制作方法。该面罩结合了硅树脂内衬的使用和面部区域的机械压力。
通过用石膏覆盖面部形成阴模。软组织的操作是这个过程中的关键部分。阴模硬化并移除后，形成阳模并干燥。接下来，在真空环境中将一卷硅树脂片放置在阳模上。随后，硅树脂硫化。然后制作面罩的刚性外部。接着将硅树脂内衬和外壳固定。
所描述的技术可制作出贴合精确的面罩。在治疗过程中，随着疤痕和畸形的重塑，面罩需多次调整以保持良好的贴合度。
面罩是减少面部过度疤痕形成的一种公认的治疗方式。它们需要良好的贴合度才能取得满意的效果。为了更好地理解面罩治疗，本研究描述了手工制作技术。
