Abstract
During the past decade, studies on facial pain have shown that there is a distinct group of patients who have a form of facial neuralgia that has all the characteristics of tension-type headache, except that it affects the midface; it is called midfacial segment pain. The pain is described as a feeling of pressure, although some patients might feel that their nose is blocked when they have no nasal airway obstruction. Midfacial segment pain is symmetric, and it might involve areas of the nasion (the root of the nose), under the bridge of the nose, on either side of the nose, the peri- or retro-orbital regions, or across the cheeks. There might be hyperesthesia of the skin and soft tissues over the affected area. Nasal endoscopy and CT scans are typically normal. Most patients with this condition respond to low-dose amitriptyline, but noticeable improvement might require up to 6 weeks.
