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.
When linked to the clinical response this study provides evidence that the serotonergic system is involved in the modulation of chronic MFP. Serotonin levels are sex-dependent and related to treatment response.
Integrating theories of behavior change into educational interventions at the primary-care level may translate to improved care, reduced long-term complications, and better quality of life.
So-called 'sinus pain' is a common complaint in GP and ear, nose and throat clinics, and patients often receive treatment with antibiotics and decongestants. Recent evidence suggests that facial pain may not be related to the sinuses at all and that doctors may have to rethink their prescribing strategy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
