Abstract

Abstract: A number of studies have already examined gluteal reconstruction with free flaps. Thus, the aim of this study was to investigate the reliability of free flap reconstruction for oncologic gluteal defects. This retrospective cohort study included 23 patients who underwent immediate soft tissue reconstruction for an oncologic gluteal defect. Fifteen patients underwent reconstruction with a free flap and 8 with a regional flap. The postoperative results were compared between the free and regional flaps. In the free flap group, the latissimus dorsi musculocutaneous flap was used in 12 patients, the thoracodorsal artery perforator flap in 2 patients, and the anterolateral thigh flap in 1 patient. Recipient vessels were the inferior gluteal vessels or their branches in 8 patients and the superior gluteal vessels or their branches in 7 patients. All flaps have fully survived in both groups without vascular compromise. Dehiscence of the gluteal wound tended to be more common in the regional flap group; however, the difference between the groups was not statistically significant. The use of free flap reconstruction for large oncologic defects in the gluteal region is a feasible and reliable option. Tension-free wound closure and simplified suture lines can provide reliable wound coverage irrespective of the postoperative patient's position or movement. Because of the risk of postoperative compression on the vascular pedicle, selecting the appropriate recipient vessel and type of microvascular anastomosis is key for the success of free flap transfer in this region.
