Clinical InformationClinical

  • Synkinesis

    an involuntary movement accompanying a volitional movement. it often refers to facial movements that accompany facial paralysis.

  • Facial Paralysis

    severe or complete loss of facial muscle motor function. this condition may result from central or peripheral lesions. damage to cns motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. facial nerve diseases generally results in generalized hemifacial weakness. neuromuscular junction diseases and muscular diseases may also cause facial paralysis or paresis.

Patient EducationClinical

Eyelid Disorders

Your eyelids help protect your eyes. When you blink, your eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. You close your eyelids when you see something coming toward your eyes. This can help protect against injuries.

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.
