Complication outcomes in retroauricular interpolated flaps after Mohs surgery: A single-center retrospective study.

When comparing surgical stages, bleeding complications were ninefold more likely to occur following flap placement than following takedown, whereas surgical site infections were twofold more likely following takedown than after placement.

Diabetes was associated with a twofold increase in odds of complication.

Each 1 cm 2 in postoperative defect size was associated with a 6% increase in odds of complication.

Cartilage grafts, intermediate stages, immunosuppression, and antithrombotic use were not associated with increased odds of complication.
