Temporal artery biopsy: concise guidelines for otolaryngologists.

Abstract

Temporal arteritis, also known more accurately as giant cell arteritis (GCA), is a multisystem vasculitis of elderly people that involves large and medium-sized blood vessels with a particular predilection to the craniofacial branches of the carotid arteries, especially the temporal artery. Symptoms include visual loss, headaches, fever, audiovestibular symptoms, and jaw claudication. Otolaryngologists are consulted to care for these patients to confirm the diagnosis, to rule out other causes of face pain and headaches, to care for patients with audiovestibular manifestations of GCA, and to perform temporal artery biopsies. Consequently, it is important for consultants to understand the signs and symptoms and natural history of GCA and the indications, technique, and complications of temporal artery biopsy. GCA can appear with protean head and neck manifestations. Otolaryngologists should be aware of these and understand the issues concerning maximizing the yield from temporal artery biopsies.
