[Application of photodynamic therapy combined with compound betamethasone in treatment of hypertrophic scar].

OBJECTIVE

To investigate the effect of photodynamic therapy combined with compound betamethasone in the treatment of hypertrophic scar.

METHODS

37 cases of keloid were divided into two groups, 19 cases in the treatment group, 18 cases in the control group. The patients in treatment group were treated with photodynamic therapy combined with compound betamethasone injection therapy. The patients in the control group were treated by compound betamethasone injection. The effect and recurrence rate were compared before and after treatment.

RESULTS

The effective rate was 89.5% in the treatment group, 55. 6% in the control group, showing significant difference between the two groups (P = 0.029) The relapse rate in treatment group was significantly lower than that in the control group (P = 0.047)

CONCLUSIONS

Photodynamic therapy combined with compound betamethasone has good effect and safety for the treatment of hypertrophic scar. The combined treatment can reduce the treatment period and side effects
