Total aesthetic reconstruction of postburn bilateral breast loss using transverse myocutaneous gracilis free flaps: A case report and literature review

Reconstruction of breast burns are challenging, as it includes both functional and aesthetic components. Transverse myocutaneous gracilis (TMG) flap has been used for postmastectomy breast reconstruction in the absence of abdominal donor site availability. Use of this flap for the breast burns is limited. A 32‐year‐old female sustained 54% second and third degree burns resulting with bilateral total breast loss. Anterior and posterior thorax, upper and mid abdomen, neck, shoulders, and bilateral upper extremities were also involved. Inner medial thighs had an ample amount of tissue and had never been used as donor sites. The left TMG (28 × 12 cm, 1,413 g) was used for right, and the right TMG (30 × 14 cm, 1,635 g) was used for the left breast, 3 months apart. The contracture on the chest wall was completely excised. Venous anastomosis to the venae commitantes was performed using a 2.5 mm coupler, followed by an end‐to‐end arterial anastomosis to the internal mammary artery. Flaps were inset in a fashion so that the inferior part became the inframammary fold, and the anterior and posterior wings were joined in the upper pole, creating a conical shape. Minimal wound dehiscence in the postoperative course healed with dressing changes and both flaps survived completely. Nipple reconstruction and areolar tattooing was performed. The patient was very happy with the outcome at seventh year follow‐up. TMG may be a valuable option even in bilateral cases of microsurgical autologous free tissue transfer for total aesthetic reconstruction of postburn breast loss.
