Key points
When facial asymmetry appears, use onset, jaw function, eye or ear changes, and neurological warning signs to decide which evaluation should come first.

Hello, I’m Dr. Hong Myeong-hwi, Chief Physician at HyungInJae Korean Medicine Clinic Gangnam.
“One side of my face looks different. Should I start with Korean medicine, dentistry, or a hospital?” This often comes up during facial asymmetry consultations. A facial midline alone can’t answer it. The order depends on when the change began, whether it hurts, whether chewing or jaw movement changed, and whether eye, ear, sensation, or speech symptoms appeared with it.
I ask about the timeline before measuring appearance. A long-standing difference and facial drooping that began today don’t belong on the same pathway. I also won’t label something a bone or muscle problem from a photograph.
If it started suddenly today, check neurological symptoms first
If one side of the face suddenly droops or feels weak, don’t spend time comparing smiles. Check for weakness or numbness in one arm or leg, slurred or difficult speech, trouble understanding, changes in vision, difficulty walking or balancing, or a sudden severe headache with no known cause. If any are present, note when they began and call emergency services immediately. Don’t drive yourself.
I don’t advise waiting even if the symptoms clear after a few minutes. Sudden new weakness limited to the face, or difficulty closing one eye, also needs same-day assessment by an appropriate medical service rather than more photographs. Emergency evaluation comes first. A Korean medicine consultation cannot precede it.
Pain, limited opening, or a changed bite points to a jaw-function assessment
When the lower face looks uneven, note whether the jaw joint in front of the ear or the chewing muscles hurt. Add difficulty opening, locking, pain with chewing, or a recent change in how the upper and lower teeth meet. Dates of a jaw injury, dental procedure, orthodontic treatment, or prosthetic change also matter. These details can help a dentist or a clinician assessing oral and jaw function decide what to examine first.
A clicking sound alone doesn’t establish a disorder or a need for treatment. The US National Institute of Dental and Craniofacial Research explains that painless jaw-joint sounds are common and may not need treatment. Pain, restricted movement, locking, and a changed bite, however, should be assessed with the history and examination. I don’t start by recommending that someone grind teeth or permanently alter the bite based on chin position alone. An irreversible step deserves caution when the cause isn’t established.
Eye, ear, or sensory changes move that function to the front of the queue
Separate appearance from function. Did one eye stop closing fully, or did double vision begin suddenly? Is there new hearing loss, ringing, dizziness, reduced facial sensation, or severe pain on one side? Eye-dominant symptoms may need ophthalmic assessment first, while hearing or balance symptoms may call for an ear, nose, and throat assessment. You don’t need to identify the perfect specialty by yourself.
State the onset and the most affected function. “Since yesterday afternoon, my right eye doesn’t close fully and pain started near my ear” is useful. Don’t self-diagnose a particular condition from one symptom. The first clinician can coordinate another specialty when needed.
For a long-standing appearance difference, review change and history without rushing
If older photographs show a similar difference and there is no new functional problem, it usually doesn’t require the same pace as an emergency. Still, note whether the asymmetry recently became more noticeable and whether pain, chewing, mouth opening, eye closure, or facial sensation changed. Include prior facial or jaw injuries, surgery, and dental care. One or two older frontal photographs and an approximate onset are enough. Daily ruler measurements aren’t necessary.
The single label “facial asymmetry” can include long-standing anatomical variation, jaw-joint or chewing-muscle dysfunction, dental conditions, and neurological change. They don’t all require the same assessment. That is why I ask “What changed, and when?” before “How many millimeters?” Whether Korean medicine is appropriate should be decided individually from current symptoms and examination, after urgent medical or dental needs have not been missed.
