Background Reconstruction of recurrent head and neck malignancy especially in the presence of a frozen neck is challenging. The superficial temporal vessels would be ideal as recipient vessels because they lie out of the previous surgical and radiation field. Methods We conducted a retrospective case‐control study based on our database between January 2013 and June 2016. A total of 581 primary cases were selected as controls. The 60 test group patients had (a) recurrent head and neck reconstruction, (b) previous surgery and irradiation, (c) frozen neck, and (d) superficial temporal vessels as recipients. Results There was no significant difference between vascular compromise rates of superficial temporal vessels (anterograde and retrograde limbs) and controls (P > .05). Flap success rate of the test and control group is comparable, 95% vs 98% respectively. Conclusion Superficial temporal vessels, both anterograde and retrograde, should be the first consideration for recurrent intraoral, facial, and scalp reconstruction with frozen necks.

Theoretically, a flap can be supplied by any perforator based on the angiosome theory. In this study, the technique of free-style perforator flap dissection was used to harvest a pedicled or free skin flap from a previous free flap for a second difficult reconstruction. The authors call this a free-style puzzle flap. For the past 3 years, the authors treated 13 patients in whom 12 pedicled free-style puzzle flaps were harvested from previous redundant free flaps and recycled to reconstruct soft-tissue defects at various anatomical locations. One free-style free puzzle flap was harvested from a previous anterolateral thigh flap for buccal cancer to reconstruct a foot defect. Total flap survival was attained in 12 of 13 flaps. One transferred flap failed completely. This patient had received postoperative radiotherapy after the initial cancer ablation and free anterolateral thigh flap reconstruction. Another free flap was used to close and reconstruct the wound. All the donor sites could be closed primarily. The free-style puzzle flap, harvested from a previous redundant free flap and used as a perforator flap to reconstruct a new defect, has proven to be versatile and reliable. When indicated, it is an alternative donor site for further reconstruction of soft-tissue defects.
