Temporal artery biopsy technique: a clinico-anatomical approach

A positive temporal artery biopsy is required to conclusively establish the diagnosis of temporal arteritis. The temporal artery biopsy technique we describe is based on the anatomical branching patterns of the superficial temporal artery, the various fascial layers, and the location of the temporal branches of the facial nerve. Special emphasis is placed on avoiding facial nerve trauma during a biopsy of the frontal branch of the superficial temporal artery. Proper surgical technique combined with a working knowledge of the anatomy of the temporalis region enhances the safety of a temporal artery biopsy procedure.
