Background: Patients often present with facial pain ascribed to sinusitis, despite normal nasal endoscopy and sinus computed tomography. Facial pain is increasingly recognised to be of neurological origin.
Method: A cohort of 240 patients with chronic facial pain was followed up for 36 months at an otolaryngological practice in Malta. The types of facial pain were classified according to International Headache Classification criteria. The body mass index, occupation and educational level of patients were compared with the general population.
Results: Tension-type mid-facial pain and facial migraine without aura were the most common types of chronic facial pain. The sites of pain, symptoms, treatment and outcomes for these principal pain types are discussed. Patients with mid-facial pain were treated with low-dose amitriptyline for eight weeks. After three years, nearly half of the patients were symptom free, and in a third the pain changed from being chronic to being episodic. The treatment of patients with facial migraine was more varied but the length of time until recurrence of pain was similar.
Conclusion: The most effective long-term treatments for tension-type mid-facial pain and facial migraine were low-dose amitriptyline and low-dose amitriptyline and triptans, respectively.
