The authors applied the thoracic free flaps to two cases of head and neck cancer surgery. An example of a giant squamous carcinoma of the left submandibular gland with a palpable palpable mass of 10 cm in diameter at the bottom of the mouth, cervical lymph node dissection, partial sublantotomy and submandibular skin resection, Of the free flap (with 10 cm long thoracodorsal artery and venous pedicle) to the wound. Another case of the right basal forehead and transferred to the parotid glandular basal cell carcinoma, about 14 × 12 cm size, made head and face primary tumor resection, total parotid gland resection and partial removal of the ear after the left lateral chest to take 14 × 18 cm of free flap (with a 9 cm thoracodorsal and venous pedicle and a part of the latissimus dorsi) to repair the soft tissue defect. The range of free flaps available on the thoracic wall is included in a rhomboid area with the upper axillary artery and the anterior border as the outer edge of the pectoralis major muscle.The posterior bound is the medial margin of the latissimus dorsi and the lower bound is between the 6th and 8th ribs between.
