The Facial Artery Perforator Flap

Reconstruction of facial melanoma defects can be challenging. Large defects of the midface, cheek, and nasolabial fold are often reconstructed using a cervicofacial flap which requires significant flap elevation and undermining. Surgeons are often hesitant to commit to such a large reconstruction without definitive pathologic evidence of negative margins. However, local perforator flaps may be used as an alternative to large flaps with less dissection and donor site morbidity and may also allow for more facile re-advancement in the event of a positive margin on final pathology. The goal of this study is to evaluate a perforator flap based on the facial artery to determine if it is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface.

A retrospective review of all melanoma cases performed by the senior author between January 2016 and December 2021 was conducted. Patients who underwent reconstruction using a facial artery perforator flap were included.

Sixteen patients were included in our cohort. The average age was 67.3 years and 53% (n=8) were female. Fourteen patients had the primary defect located on the cheek, 1 from the nasolabial fold, and 1 from the distal nasal sidewall. All patients received immediate reconstruction. Excisional margins ranged from 0.5 to 2 cm. Two patients had positive margins following pathology results with one undergoing treatment with imiquimod and the other opting for re-excision. No complications involving the defect or donor site were reported after an average follow-up time of 113.8 days.

The facial artery perforator flap is a safe and cosmetically favorable option to immediately repair oncologic-related defects on the cheek and midface.
