Outcome and Prognosis
In conclusion, many variations and modifications of transposition flaps exist. Similar to other flaps, transposition flaps may be further modified and adjusted to accommodate individual situations. They may be lengthened or shortened, and their angles may be altered depending upon the availability and laxity of surrounding skin.
Future and Controversies
No single flap can be used to reconstruct all defects. Each patient must be treated with a unique strategy. A 2-dimensional picture of a given defect may seem to indicate a certain type of repair. This may or may not be the optimal repair for that given patient. Only by feeling the skin in the area around the defect may the best option for repair be determined.
Transposition flaps dissipate tension away from the flap apex and distribute it proximally, thus redirecting the tension lines and reducing the likelihood of anatomic distortion in the reconstructed area; this is a major advantage offered by the use of these types of flaps. Flaps designed in this manner allow improved contour by avoiding webbing, tenting across concavities, and bunching of skin laterally.
A significant degree of artistic ability and individual modification is required to consistently obtain optimal aesthetic and functional result.
