Everybody has two facial nerves, one on each side of the face that control muscles to make expressions (e.g., smiling, frowning and winking). Facial nerve problems interfere with these processes and can result in weakness or paralysis of the face. This occurs anytime the facial nerve fibers become irritated or disrupted. A number of conditions can cause facial paralysis, including infections, fractures and injuries, strokes, tumors, toxins, and disorders such as Lyme disease and Sarcoidosis, but the most common is Bell’s Palsy.

Those most likely to experience facial nerve problems are 40 or older, have diabetes, weakened immune systems, or upper respiratory disorders. Pregnant women are especially susceptible.

Signs of Facial Problems

Symptoms associated with facial problems include any or all of the following:

  • Facial weakness or paralysis
  • Facial droopiness or swelling
  • Twitching facial muscles
  • Trouble blinking or closing one eye
  • Difficulty speaking, eating and drinking
  • Earache
  • Drooling
  • Sensitivity to sound


Diagnosis and Treatment

Facial nerve problems are diagnosed through a series of tests. These might include:

  • A complete review of medical history and current symptoms
  • A physical exam, including a look at facial symmetry and movement
  • Tear, taste, salivation, and blood tests
  • Hearing and balance tests to gauge auditory nerve responses
  • Imaging exams such as CT or MRI scans to look for tumors, fractures, or infection
  • Electrical exams such as electromyography, electroneuronography, or a nerve excitability test to gauge facial nerve function

Many cases of facial paralysis are temporary and end up resolving on their own, though side effects (muscle spasms and weakness, changes in taste) often linger.

The treatment given will focus on correcting the source of the nerve damage. Infections are treated with antibiotics, while surgery to remove bone in the vicinity of the facial nerve can help correct some abnormalities. Steroids can be given to combat facial swelling, and physical therapy may be prescribed for long-term results.
