Objective:To observe and compare the wound healing effects

the time and costs of hospitalization of the two drainage ways in the breast polyacrylamide hydrogel removing operations by a prospective randomized controlled approach.Methods:From December 2004 to December 2009

a total of 54 breast-side of 40 patients

whose incision were not healing after breast polyacrylamide hydrogel removing operations

were divided into two groups.Both gorups’skin incision were on the areola or inframammary crease.In the case of removing the polyacrylamide hydrogel during the operation as much as possible

a new incision

approximately 1.5cm

was produced below the inframammary crease approximately 5cm

the negative drainage tube was inserted into the new incision in the A group(distal drainage way)

While the negative drainage tube was inserted into the original incision in B group(In-situ drainage way).Results:The breast appearance was flat and thin

the texture was soft and there was no mass or sclerosis.There were significant differences between the two methods in primary healing

the time and costs of hospitalization.Conclusion:The clinical effect of the distal drainage way is better than the clinical effect of the In-situ drainage way

and it deserves to apply in clinical practice.
