Medical Care
Medical treatment of PIFP is usually less satisfactory than medical treatment for other facial pain syndromes.
Medications used to treat PIFP include antidepressants, anticonvulsants, substance P depletion agents, topical anesthetics, N -methyl-D-aspartate (NMDA) antagonists, THC/CBD receptor agonists, and opiate medications. Of these classes of medications, anticonvulsants and antidepressants appear to be the most effective. The neuropathic component of pain responds well to anticonvulsants and antidepressants.
Pharmacotherapeutic knowledge is paramount in the treatment of this refractory pain syndrome. A multimechanistic approach, using modulation of both ascending and descending pain pathways, is frequently necessary. The goal of therapy is to manage the pain effectively with the fewest adverse medication effects.
Anticonvulsants and antidepressants are the mainstays of medication treatment. Narcotics may be appropriate if administered under careful supervision.
Alternative therapies such as acupuncture and neuromuscular reeducation have been tried and should be considered as part of a comprehensive treatment plan.
Psychiatric treatment is important in the overall management of a patient with chronic pain.
Available data on alternative treatments are limited.[18, 19]
Surgical Care
Details of neurosurgical interventions are beyond the scope of this review. Analgesic surgery should be considered at a center well versed in these procedures.
Consultations
Psychometric testing may be of benefit in the evaluation and treatment of patients with headache and facial pain. Many tests have been applied, but probably the most widely used is the Minnesota Multiple Personality Inventory (MMPI). While especially useful in the evaluation of the chronic headache and facial pain patients, a thorough discussion of psychometric testing is beyond the scope of this discussion and is mentioned here only for completeness.
Consultation with a dentist may be of benefit.
All treatments should be provided in cooperation with the patient's primary care physician.
