Abstract:
Objective:To explore the clinical effects of flaps with cervical cutaneous branch of transverse cervical artery in repairing neck radiation ulcer.Methods:The retrospective observational research was conducted. From January 2016 to December 2019, 8 cases with neck radiation ulcer were admitted to Guangzhou Red Cross Hospital of Jinan University and repaired with flaps based on cervical cutaneous branch of transverse cervical artery. There were 6 males and 2 females, aged 52-75 years. The ulcers occurred 14.5 years after radiotherapy on average, with ulcer areas of 5.0 cm×3.0 cm-7.0 cm×6.0 cm on admission. The wound areas were ranged from 6.0 cm×5.0 cm to 13.0 cm×6.5 cm after ulcers and fibrotic tissue around were resected. Seven cases underwent resection of flaps and wound repair operation on the first stage, and the other 1 case underwent pre-expansion of flap donor area on the first stage and resection of flap and wound repair operation on the second stage, with flap sizes of 8.0 cm×7.0 cm-15.0 cm×8.5 cm. The wounds in the donor areas of flaps in 7 patients were sutured directly, and the wound in the donor area of flap in the other 1 patient was repaired with thin split-thickness skin graft from thigh after being sutured partially. The preoperative ulcer tissue was collected for pathological examination, and the postoperative survival of the flaps and healing of the flap donor areas were observed. The flaps, the recurrence of the neck ulcers and neck function, and the scar hyperplasia in the donor areas of flaps were observed during follow-up.Results:Preoperative pathological examination of ulcer tissue showed that full-thickness necrosis occurred in ulcer skin, obvious fibrotic tissue hyperplasia, collagenization, and small-scale calcification in the base and surrounding tissue of the ulcers, and a large amount of chronic inflammatory cells and a small amount of acute inflammatory cells infiltration were observed in intercellular substance, which excluded the recurrence of tumor. All the flaps in 8 cases survived, the wounds were repaired effectively, and the postoperative donor areas of flaps healed well. During postoperative follow-up of 6-24 months, the flaps had good appearances without recurrence of ulcer, the movement function of neck was significantly improved, and no obvious scar hyperplasia was observed in the donor areas of flaps.Conclusions:Radiation ulcer in the neck is a serious long-term complication of neck after radiotherapy, which is difficult to heal with conservative treatment. The flap with cervical cutaneous branch of transverse cervical artery is close to the neck, with rich blood supply, constant anatomy, and is easy to cut. Neck radiation ulcers treated with the flaps showed good wound healing and improved functions, with no obvious scar hyperplasia.
