See the list below:

  • When performed by a trained physician, temporal artery biopsy is a safe procedure.

  • The serious risks of biopsy include injury to the branches of the auriculotemporal or facial nerve, [11] bleeding, wound infection, and hematoma formation.

  • The more common minor complications include incisional alopecia, widening of the scar, and foreign body reaction to entrapped hairs.

  • Another common occurrence is a nondiagnostic pathologic result, which can generally be avoided if the segment of artery removed is large enough.
