Objective To explore the early application of adjustable support protector in penis reconstruction.Methods From January 2015 to July 2017,30 cases received penis reconstruction were selected and divided into the experimental group(n=15)and the control group(n=15).The control group was given the thick cotton pads after operation,and the experimental group was given the adjustable support protector to replace the heavy cotton pad.The survival rate of the penis flap,the accuracy of the fixed angle of the penis and the sensory function improvement were compared between the 2 groups after operation.Results The survival rate of the penis flap,the accuracy of the fixed angle of the penis,the infection rate and the sensory function improvement in the experimental group were significantly better than those in the control group after operation(P<0.05).Conclusion The adjustable brace can effectively protect the skin flap in early stage after penis reconstruction.The effect is better than heavy cotton pad,which is more conducive to early rehabilitation after operation.
