Pathogenesis (development of disease)
Facial pain can have multiple causes (see Differential diagnoses below).
Persistent idiopathic facial pain (IHS 13184) must meet the following criteria:
- A. Facial pain that meets criteria B and C is present daily and for most of the day.
- B. Initially, facial pain is confined to a circumscribed region of one side of the face, is deep-seated, and is difficult to localize.
- C. The pain is not accompanied by a sensory deficit or other physical findings
- D. Examinations including radiographs of the face and jaw show no relevant pathologic (pathological) findings.
Etiology (causes)
- Initial trigger may be trauma (injury) or surgery in the ENT or dental, oral and maxillofacial region (e.g. tooth extraction (tooth removal), apicoectomy, root canal treatment, etc.), but there is currently no pathological local finding. (Frequency: approx. 40%)
- Critical life events are described in about 20 of the cases as triggering
