Abstract

Objective To analyse the clinical efficacy of combined therapy of super-pulsed CO2 laser and traditional Chinese medicine on the prevention and treatment of post-traumatic hypertrophic scar, and to discuss effective comprehensive therapy for hypertrophic scars. Methods 108 cases of early post-traumatic hypertrophic scar were divided randomly into three groups with 36 cases each: combined treatment group of super-pulsed CO2 laser and traditional Chinese medicine (combined group), Chinese medicine treatment group (Chinese medicine group) and simple laser-treated group (laser group). They were regularly treated for 6 months and followed up for longer than 1 year. Clinical effects were evaluated according to scar property and subjective symptoms in patients. Results The total effective rate was 97.2 % and 86.1% in combined group and Chinese medicine group that were higher than 61.1 % in laser group. Obviously effective rate of the three methods were 55. 6 %, 27.8 % and 11. 1 %, respectively, and the difference of obviously effective rate between combined group and other two groups was significally different. Conclusion The method combined with super-pulsed CO2 laser and traditional Chinese medicine for prevention and treatment of post-traumatic hypertrophic scar has advantages of high obviously effective rate, long-term and stable effects, less complication, and it can achieve satisfactory cosmetic effects.
