Clinical Classification

Clinical Information

  • Facial Neuralgia

    neuralgic syndromes which feature chronic or recurrent facial pain as the primary manifestation of disease. disorders of the trigeminal and facial nerves are frequently associated with these conditions.
  • Facial Hemiatrophy

    a syndrome characterized by slowly progressive unilateral atrophy of facial subcutaneous fat, muscle tissue, skin, cartilage, and bone. the condition typically progresses over a period of 2-10 years and then stabilizes.
  • Facial Pain

    pain in the facial region including orofacial pain and craniofacial pain. associated conditions include local inflammatory and neoplastic disorders and neuralgic syndromes involving the trigeminal, facial, and glossopharyngeal nerves. conditions which feature recurrent or persistent facial pain as the primary manifestation of disease are referred to as facial pain syndromes.
  • Facial Hemiatrophy

    progressive atrophy of the tissues that comprise half of the face.

Patient Education


Facial Injuries and Disorders

Face injuries and disorders can cause pain and affect how you look. In severe cases, they can affect sight, speech, breathing and your ability to swallow. Fractures (broken bones), especially in the bones of your nose, cheekbone and jaw, are common facial injuries.

Certain diseases also lead to facial disorders. For example, nerve diseases like trigeminal neuralgia or Bell's palsy sometimes cause facial pain, spasms and trouble with eye or facial movement. Birth defects can also affect the face. They can cause underdeveloped or unusually prominent facial features or a lack of facial expression. Cleft lip and palate are a common facial birth defect.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
