AbstractObjective: To explore the clinical effects of scapular region flaps pedicled with circumflex scapular artery in the reconstruction of axillary burn scar contractures. Methods: From December 2008 to December 2018, 21 patients with axillary burn scar contractures were admitted to our department. There were 12 male patients and 9 female patients, aged 2-48 years, with an average of 17.4 years. According to the characteristics of axillary scar contractures, the patients were divided into type Ⅰ of 5 patients, type Ⅱ of 2 patients, type Ⅲ of 5 patients, and type Ⅳ of 9 patients. The preoperative abduction ranges of shoulder joint were 20-150°, with an average of 68.33°. The wound areas after resection and release of scar contractures ranged from 12 cm×4 cm to 33 cm×11 cm, with an average of 18.13 cm×5.41 cm, and the wounds were repaired with scapular region flaps pedicled with circumflex scapular artery in the areas of 14 cm×5 cm-35 cm×14 cm, with an average of 20.19 cm×7.71 cm. The donor sites of 5 patients were expanded prior to flap repair operation, and the other 16 patients were repaired by direct transfer of flaps. The donor sites were closed directly. The type, number, and transfer way of scapular region flaps were calculated, and the improvement of abduction angle of shoulder joint and condition of the flaps were observed during follow-up after operation. Results: There were 5 ascending scapular flaps, 13 scapular flaps, and 3 parascapular flaps. The flaps were transferred through open wounds in 18 cases, subcutaneous tunnel in 1 case, and trilateral foramia in the remaining 2 cases. All the flaps survived after operation. During follow-up of 3 months to 5 years, with an average of 19.4 months, the abduction angles of shoulder joints were 90-180°, with an average of 137.62°, which showed that the abduction function of shoulder joint improved obviously. The texture of flap was soft, and the color of the flap was close to the surrounding skin. The patients and/or their family members were satisfied with the operation results. Conclusions: The scapular region flap pedicled with circumflex scapular artery has a lot of advantages, including a long vascular pedicle, simple technique for flap harvest, a hidden donor site, and flexible and diverse transfer mode of flap. It is an effective option for clinical reconstruction of severe axillary burn scar contracture.
