Background:
With proper training, superficial temporal artery biopsy is a safe office procedure with few complications. Surgeons from different disciplines, including ophthalmologists, dermatologists, general surgeons, and plastic surgeons may be called upon to perform this common procedure to confirm giant cell arteritis.
Objective:
To emphasize the surgical anatomy of the scalp as it pertains to superficial temporal artery biopsy and to raise awareness that significant complications can occur after superficial temporal artery biopsy.
Method:
Case report.
Results:
A 75-year-old woman with presumed giant cell arteritis developed frontalis muscle paralysis following a superficial temporal artery biopsy. Biopsy selection site within the danger zone combined with deep dissection carries the greatest risk of injury to the temporal branches of the facial nerve.
Conclusion:
Any surgeon involved in the practice of performing superficial temporal artery biopsies should have a thorough understanding of proper surgical techniques and regional anatomy to avoid potential devastating complications.
