Reconstruction of axillary scar contractures--retrospective study of 124 cases over 25 years

We present a retrospective study of 134 axillae treated in 124 cases of axillary scar contractures with the use of skin grafts and various flaps over the last 25 years in our department. Free skin grafts were performed in 25 axillae, and local flap transfers including skin elongation procedures such as z-plasty were performed in 76 regions. As regional flap transfers, i.e. pedicled axial local flap transfers, latissimus dorsi flaps, para-scapular flaps, superficial cervical artery flaps (SCA flap) and bilateral combined scapular flaps were used for the reconstruction of 23 severe axillary scar contractures. Free flaps and scarring flaps were also used for five severe contracture cases. The results were generally satisfactory, but five problematic cases and seven cases of recurrence were encountered. In this report, we classify axillary contractures into five types and present our conclusions on the criteria for selecting appropriate surgical methods according to contracture type. Our results suggest there are four key scar features to be considered in the selection of surgical methods for axillary reconstruction: (1) size; (2) depth; (3) location and (4) shape. We also discuss and evaluate the various methods of reconstruction.
