For facial scars after burns (trauma), elastic fabric masks were often used in the past for pressure therapy, which had a certain therapeutic effect, but the effect was poor, especially for depressed scars, such as around the eyes, dorsum of the nose, next to the nose, under the lower lip, due to the reduction of pressure after the opening of the pressure is uneven or no pressure, the efficacy of the treatment was affected. In addition, the patient’s appearance is poor when wearing an elastic mask, and the pressure applied inside the mask cannot be directly observed. Application of rigid transparent mask for facial scar treatment, the mask is based on the patient’s facial contour to take the mold copied from the three-dimensional model, and the shape of the face match better, after the repair of the mold to wear, the first pressure is the raised scar, will not be affected by the shape of the face; the material is transparent and easy to observe, and can be better pressure and play a role in fixing the face, to prevent the scar from pulling the face to deformity. In addition, the mask can be trimmed repeatedly, always keeping the scar in the best pressure state. The mask made of SC-699 Silcon-sts high temperature thermoplastic sheet also has the dual function of pressure and silicone gel for scar treatment, and the transparent mask can also be used with silicone gel diaphragm for joint treatment. Already proliferated facial scar, the application of mask treatment can make it soften and inhibit its continued proliferation, so that the patient to maintain a certain shape of the face, for some contractural scar, can limit its contracture and be corrected. When wearing the transparent mask at an early stage after wound healing, the scar hyperplasia is not obvious and the effect is especially good; even if the scar hyperplasia occurs to varying degrees at a later stage, the effect is also better than that of the previously observed elastic mask treatment, especially for the depressed scar. Another advantage of this mask is that for localized hypertrophy and severe hyperplasia of keloid scars, without affecting the overall treatment effect of the face, the special mask can be used for localized key pressure treatment.
