Thoraco dorsal artery perforator flap for trismus release in a young girl.

Trismus is a frequent complication occurring after treatment of tumors of the pterygomaxillary fossa. Local flaps and full-thickness skin grafts fail to release it because they usually lead to scar contracture in previously irradiated tissues. We propose to release it with a thoracodorsal artery perforator flap, which is feasible in children like other perforator flaps. It is interesting because it is thinner than the anterolateral thigh flap and its scar may be less disgraceful and easier to hide.
