Temporomandibular dysfunction: an often overlooked cause of chronic headaches

TMD is a likely underdiagnosed cause of chronic headache and facial discomfort. As such, many patients with the disorder are routinely mislabeled as experiencing chronic sinusitis and are unnecessarily subjected to multiple courses of broad-spectrum antibiotics and other unnecessary therapy. TMD can be readily diagnosed by a careful history and physical examination. Patients typically respond well to conservative therapy, which includes behavioral modification and nonsteroidal anti-inflammatory drugs. The disorder should be suspected in individuals with a long-standing history of chronic daily headaches and facial pain without objective evidence of sinus, neurologic, or intracranial abnormalities.
