Classification and surgical correction of postburn axillary contractures.

Postburn axillary contractures should be surgically corrected as soon as the diagnosis has been established in order to avoid deeper tissue involvement. We have classified axillary contractures based upon local anatomic conditions and present procedures for correction of each type that we find most suitable. Type I contractures are characterized by a linear web at either axillary fold with minimal adjacent scarring. A double Z-plasty with Y-V advancement is the procedure of choice. Type II contractures involve either axillary fold, with adjacent skin scarring. A double incisional release on both sides of the hair-bearing area is the procedure of choice. Type III contractures are characterized by linear webs at both axillary folds without involvement of the adjacent skin. The procedure of choice in these cases is a double incisional release. Type IV axillary contractures involve the hair-bearing area and the periaxillary region. This diffuse scar contracture is best treated by a single incisional release.
