Atypical facial pain (AFP) is a type of chronic facial pain which does not fulfill any other diagnosis. [1] There is no consensus as to a globally accepted definition, and there is even controversy as to whether the term should be continued to be used.
The pain frequently involves areas of the head, face, and neck that are outside the sensory territories that are supplied by the trigeminal nerve. It is important to correctly identify patients with AFP since the treatment for this is strictly medical. Surgical procedures are not indicated for atypical facial pain." [8] [citation needed]
Trigeminal neuralgia (TN or TGN), also called Fothergill disease, tic douloureux, trifacial neuralgia, or suicide disease, is a long-term pain disorder that affects the trigeminal nerve, [7] [1] the nerve responsible for sensation in the face and motor functions such as biting and chewing.
The pain may be referred in around half of all patients and experienced as otalgia (earache). [50] Conversely, TMD is an important possible cause of secondary otalgia. Treatment of TMD may then significantly reduce symptoms of otalgia and tinnitus, as well as atypical facial pain. [51]
Toothache which has no identifiable dental or medical cause is often termed atypical odontalgia, which, in turn, is usually considered a type of atypical facial pain (or persistent idiopathic facial pain). [36] Atypical odontalgia may give very unusual symptoms, such as pain which migrates from one tooth to another and which crosses anatomical ...
The features are highly variable and may mimic sinusitis, temporomandibular disorders, headaches, ear pain, or atypical facial pain/atypical odontalgia (persistent idiopathic facial pain). [2] When diagnosing cracked tooth syndrome, a dentist takes many factors into consideration.
Mesencephalotomy is the damaging of the junction of the trigeminal tract and the periaqueductal gray in the brain, and has produced pain relief in a group of patients with cancer pain; but when applied to six anesthesia dolorosa patients, no pain relief was achieved, and the unpleasant sensation was in fact increased.
Possible exacerbating factors (make the pain worse) include tension, fatigue, speaking, and hot, acidic or spicy foods. Possible relieving factors include sleeping, cold, distraction, and alcohol. The pain is often relieved by eating and drinking (unlike pain caused by organic lesions or neuralgia ) or when the person's attention is occupied.
