[Clinical application of expanded flap based on the cutaneous branch of transverse cervical artery]
Objective:
To investigate the clinical application of expanded flap based on cutaneous branch of transverse cervical artery for reconstruction of cervical cicatricial contracture.
Methods:
Based on the clinical anatomy of cutaneous branch of transverse cervical artery flap, we design the corresponding subclavicular area for expansion. The incision was usually located at the anterior axillary fold, 5-8 cm in length. The expander was implanted under the deep fascial layer, without injury of the vascular pedicle. Fixation sutures were put about 1 cm apart from the incision to prevent the expander from transposition and exposure. After expansion, the cervical cicatricial contracture was excised and released. According to the defect, the expanded flap based on the cutaneous branch of transverse cervical artery was designed, with the pedicle located at the posterior margin of sternocleidomastoid and 1. 8 cm above median point of clavicle. "S" shape incision was made at the location of vascular pedicle. Subcutaneous dissection was performed 1.5 cm in width along the incision on both sides. Then the flap was harvested under the deep fascial layer and rotated to cover defect without tension. It was not necessary to dissect the vascular pedicle further. The defect at donor site was closed directly.
Results:
17 cases were treated with the island flap. The contracture of the cervical scar was corrected completely with aesthetic appearance.
Conclusions:
Expanded flap based on cutaneous branch of transverse cervical artery has reliable blood supply. It' s an ideal flap for the treatment of cervical cicatricial contracture.
