Superficial Temporal Artery Pseudoaneurysm and Wound Dehiscence Following Rhytidectomy and CO2 Laser Resurfacing in a 52-Year-Old Female

Abstract

Introduction:

A 52-year-old female underwent rhytidectomy of the lower face and neck and full-face CO2 ablative laser resurfacing.

Materials and Methods:

The patient developed a small left postauricular neck hematoma 10 days postoperatively, which was drained without sequelae in the office setting. Approximately 5 weeks following her index procedure, she presented with a left preauricular fluctuant, nonpulsatile swelling with overlying soft-tissue erythema.

Results:

The left preauricular site was initially needle aspirated, resulting in hemorrhage from the site. Immediate surgical exploration revealed a superficial temporal artery pseudoaneurysm, successfully managed with bipolar electrocautery.

Discussion:

Subsequent wound dehiscence of the preauricular area and skin necrosis were treated with hyperbaric oxygen therapy (HBOT) and wound care, achieving secondary healing with minimal scarring after 6 weeks.

Conclusion:

This case illustrates a rare vascular complication that can masquerade as a nonvascular sequela, followed by the use of effective multidisciplinary management for wound healing in cosmetic surgery.
