Sinogenic facial pain: diagnosis and management.

Most patients who present to an otorhinolaryngology clinic with facial pain and headaches believe they have sinusitis. There is an increasing awareness that neurologic causes are responsible for a large proportion of patients with headache and facial pain. If facial pain and pressure is the primary symptom, it is unlikely to be caused by sinus disease in the absence of any nasal symptoms or signs. Patients with facial pain who have no objective evidence of sinus disease are unlikely to be helped by surgery. Most patients with pain caused by sinusitis respond to medical therapy.
