DELAY BETWEEN EXPANSION AND EXPANDER IMPLANT EXCHANGE IN BREAST RECONSTRUCTION - A PROSPECTIVE-STUDY

It has been suggested that delay between expansion and insertion of the definitive prosthesis in breast reconstruction reduces the incidence of adverse capsular contracture. We have carried out a prospective trial to examine this hypothesis. 65 patients were randomly allocated into two groups; in one, insertion of the definitive prosthesis was 2 weeks following expansion ("immediate") and in the other, 6 months ("delayed"). The incidence of adverse capsular contracture assessed both by the Baker Scale and a linear analogue scale showed no difference between the two groups. A new objective method for measuring ptosis using a specially designed template is described. The degree of ptosis was not affected by the delay.
