The Therapy for Chest Keloid Based on Skin Soft Tissue Expansion under Keloid

Objective:To study the therapy effect on chest keloid based on skin soft tissue expansion under keloid.Method:29 chest keloid patients were randomly divided into two groups,the skin expander was buried under the keloid in group A,while under the normal skin around the keloid in group B.Then both of the groups received regular water injection treatment to expansion.After reoperation to remove the dilator and to resect the keloid,radiotherapy continued for 5 days.The total length of the operation scar was measured,and the cases of complication and recurrence followed up for 6 months-2 years were counted,and the difference between the both groups was compared.Result:The total length of operation scar was(7.68±1.30)cm in group A while the length was(10.25±2.05)cm in group B,which had significant difference(P0.05),but complications and recurrence rate of two groups had no statistical difference(P0.05).Conclusion:Tissue expansion under the cicatrix has the advantages of safer,less trauma and less operation scar for chest keloid.
