Abstract:
Objective:To explore the clinical effects of pre-expanded anterior perforator flap of transverse cervical artery in extensive facial and cervical scar reconstruction and contralateral pre-expanded thoracic random flap in relay in donor site repair.Methods:A retrospective cohort study was conducted. From May 2008 to December 2018, 10 patients with extensive facial and cervical scar after burns were treated in the Fourth Medical Center of PLA General Hospital, including 8 males and 2 females, aged 10-55 years. In the first stage of operation, two skin and soft tissue expanders of the same volume (with rated capacity of 250-600 mL) were respectively placed in the right side and left side of the chest according to the size of scar, and then the skin was expanded. The total amount of normal saline injected was 2 to 4 times of the rated capacity of the expander. In the second stage, the defect with area of 12 cm×8 cm-23 cm×15 cm caused by scar resection and release was repaired with unilateral pre-expanded anterior perforator flap of transverse cervical artery with area of 12 cm×9 cm-24 cm×16 cm. The contralateral pre-expanded thoracic random flap with the same area as that of the above-mentioned perforator flap was extended to repair the secondary defect with area of 8 cm×6 cm-17 cm×14 cm formed after transfer of the above-mentioned perforator flap. The exploration of perforating branch of transverse cervical artery, flap transfer and survival, injury repair, and complications were observed. The appearance and related function of donor and recipient sites and satisfaction of patients were followed up.Results:The perforating branches of transverse cervical artery appeared stably in the 10 patients. All the flaps were transferred to the recipient area without tension and survived. Both facial and cervical injuries were repaired successfully with no common complications. During the follow-up of 6 months-8 years, the color and texture of the pre-expanded anterior perforator flap of transverse cervical artery matched with the surrounding tissue, the functions of head raising and neck rotation of patients were significantly improved compared with those before operation, the color and texture of the flap transplanted in the first donor site matched with the original skin, linear scar left at the surgical incision, and 9 patients were satisfied with the restoration of the appearance and function of donor and recipient sites.Conclusions:The color and texture of the pre-expanded anterior perforator flap of transverse cervical artery match well with the face and neck, and the repairable area is large. After the perforator flap is removed, the secondary wound can be repaired with the pre-expanded thoracic random flap at the same time, and the injury of the chest donor site is alleviated. This relay repair method is a good choice for reconstructing extensive facial and cervical scar.
