Free Tensor Fascia Lata Perforator Flap as a Backup Procedure for Head and Neck Reconstruction

Abstract

Free tissue transfer is an essential part of the head and neck reconstruction. Despite several flap options, free perforator flaps have become very popular for head and neck. Anterolateral thigh perforator flap has multiple advantages among other options and is preferred by most of the reconstructive microsurgeons. Besides its advantages, sometimes it is impossible to harvest an anterolateral thigh perforator flap, and the surgeon has to shift to another option. Between January 2002 and June 2005, 5 tensor fascia lata perforator flaps were used for head and neck reconstruction because anterolateral thigh perforator flap could not be elevated due to absence or insufficient musculocutaneous perforators. Only 1 flap was reexplored and salvaged by redoing the venous anastomosis. All flaps survived without any other problem. Donor sites were covered by split-thickness skin grafts in 4 patients and closed directly in 1 of them. Doppler examination is important in planning of anterolateral thigh perforator; if the signals of the perforators are absent or very weak, the surgeon can shift to another flap. This decision may also be made during the operation when insufficient perforators are seen. Based on our experience, tensor fascia lata perforator flap is a safe alternative when anterolateral thigh perforator harvest is not possible. Tensor fascia lata perforator flap can be harvested from the same anatomic region with almost same morbidity.
