The thoracodorsal artery perforator flap is reliable and safe for breast reconstruction, but stacking bilateral thoracodorsal artery perforator flaps for unilateral reconstruction to achieve greater volumes has not been reported. To create a stacked thoracodorsal artery perforator flap, the ipsilateral flap is transferred as an island, and the contralateral flap is transferred as a microvascular free flap. In this article, the authors present their 8-year 14- patient experience with stacked thoracodorsal artery perforator flaps for unilateral breast reconstruction. Patients' ages ranged from 33 to 72 years (mean, 52.6 years). Mean follow-up time was 48.1 months (range, 1 to 98 months). Flaps measured between 22 × 6 cm and 32 × 8 cm and weighed between 110 and 550 g. Two of the island flaps had steatofibrosis of the distal 3 cm, which was resected and closed directly. The rest of the island flaps and all 14 free flaps healed uneventfully. At the time of follow-up, all flaps appeared healthy, and the reconstructed breast had a similar appearance and volume as the contralateral side. The donor areas had almost no functional deficit, and the final scar was aesthetically acceptable, especially when the ascending oblique design was used. This represents the first description of stacked thoracodorsal artery perforator flaps for unilateral breast reconstruction. This novel addition to the reconstructive surgeon's selection of methods is a safe and reliable option for large-volume unilateral breast reconstruction. It allows for symmetry without requiring prostheses or reduction of the contralateral side.

Background: It has been established that patients with burn sequelae of the anterior neck and chest have a significant degree of flap descent and deficit in neck extension when resurfaced with a single free flap. A protocol was developed to avoid flap descent in these patients by resurfacing the neck with multiple free flaps. The purpose of this article is to present our protocol for treatment and long-term results of this technique. Methods: Twenty-five 25 patients with burn sequelae of the anterior neck and anterior thorax were retrospectively identified. Ten patients were treated with a single free flap (group 1), and 15 patients were treated with multiple free flaps (group 2). Patients were followed up for an average of 7 years after their definitive reconstructive procedure at which time measurements including flap descent from sternal notch, deficit of neck extension, and subjective reports of discomfort were obtained. Results: Patients in group 1 demonstrated 8 cm (interquartile range [IQR], 1.75 cm) of flap descent, whereas patients in group 2 demonstrated 0.5 cm (IQR, 0 cm) of flap descent. Patients in group 1 demonstrated 12.5 degrees (IQR, 10 degrees) of deficit in neck extension, whereas patients in group 2 demonstrated 0 degrees (IQR, 0 degrees) of deficit in neck extension. Analysis demonstrated significantly greater descent and deficit in neck extension in group 1 compared with group 2. Conclusions: Patients with burn sequelae of the neck and anterior chest experience less flap descent and deficits in neck extension when resurfaced with multiple free flaps.
