Comparative analysis of repeated skin dilation in the treatment of scarring baldness

Abstract

Objective To investigate the clinical effect of repeated skin expansion technique on scarring alopecia. Methods Twenty-eight cases of scarring alopecia underwent repeated relay skin expansion technique were chosen,and 21 cases of scarring alopecia underwent repeated delay skin expansion technique were chose. The times of operations,length of hospital stay,expenses and times of anesthesia were compared between the two methods. Results Relay dilatation was used to repair scarring alopecia in 28 cases,26 patients had good repairment,the average length of hospital stay was（24 ± 6）d, the average hospitalization expenses were（26 ± 3）thousand yuan. Delay skin expansion was used to repair scarring alopecia in 21 cases,20 cases of had good reparrment,the average length of hospital stay was（32 ± 4）d,the average hospitalization expenses were（38 ± 4）thousand yuan. There were significant differences in the average length of hospital stay and the average hospitalization expenses between the two methods（ P〈0 . 01 ）. Conclusions Delayed skin expansion and relayed expansion both can better repair scarring alopecia,but relayed expansion is feasible,and has fewer operation times,shorter length of hospital stay,little costs and pain.
