支具面罩治疗面部增生性瘢痕疗效的短期研究.

Objective: To investigate the effects of brace masks on controlling facial hypertrophic scars. Method: Totally 63 patients with 286 post-burn facial hypertrophic scars samples were recruited for the study. And they were divided into the brace mask group with 28 cases(152 scars), cloth mask group with 26 cases (100 scars), and control group with 9 cases (34 scars). Patients in the brace mask group and cloth mask group received eight weeks of pressure therapy, while the control group did not receive pressure therapy intervention. Pre- and post-treatment, chromatography was used to evaluate the scar color(lightness, redness and yellowness). An ultrasonic measuring instrument was used to evaluate the scar thickness. The Vancouver scar scale (VSS) was used. Patient satisfaction with eight weeks of treatment was evaluated with satisfaction scale. Result: ① Pre- and post- treatment comparison: The brightness decreased in control group and increased in mask group(P<0.001). The redness increased in control group and decreased in mask group(P<0.001). The thickness and VSS score increased in three groups bu more in control group(P=0.001). There was no change in yellowness for all the three groups(P=0.981). ②compared the two mask groups, there was no significant difference for all parameters(P>0.05). ③satisfaction: the overall satisfaction of the brace mask group and the cloth mask group are 75% and 69.2% respectively. The comfort and appearance satisfaction of the brace mask group is better than the cloth mask group. The price satisfaction of the mask group is lower. Conclusion: For the facial hypertrophic scars, this short-term efficacy study showed that the brace mask and cloth mask could improve the lightness and redness and inhibit the thickness of it. The overall satisfaction of patients is high after using brace masks and cloth masks. [ABSTRACT FROM AUTHOR]
