Abstract: Objective To search a new way of designing prosthesis for breast reconstruction.MethodsIn accordance with the contralateral uninjured breast,four dimensions including volume,transverse diameter,length wise and height were measured.The size of breast prosthesis was calculated according to the formula,and then the personalized breast prosthesis was selected from the inventory.Meanwhile,a volume of 20～25ml was added to or reduced from the breast prosthesis according to patient’s height and obesity.ResultThe four-dimension method for breast prosthetic reconstruction was adopted on 30 cases of breast cancer in postoperative phase I.The effect of the operation was satisfactory and the shape of the restructured breasts was fine.ConclusionsThe four-dimension method is exact,simple and useful for designing breast prosthesis.
