Facial Nerve Palsy (Bell's Palsy)

Symptoms such as unilateral drooping of the mouth corner with fluid leakage when drinking, incomplete eye closure, and loss of forehead wrinkles are termed facial palsy (Bell's palsy). Retroauricular pain, loss of taste, or hyperacusis may precede these signs.

At SOIAN Korean Medicine Clinic, we do not evaluate solely by mouth drooping. We test isolated movements of the forehead, eyes, cheeks, and lips to determine specific branches and functional deficits of the facial nerve, while checking lagophthalmos, tearing, otalgia, vesicles, hearing, dizziness, and jaw/neck tension. Documenting baseline status in detail ensures even subtle early recovery is captured.

If facial paralysis occurs with unilateral limb weakness, dysarthria, or sudden gait instability, an emergency evaluation for stroke must come first. Conversely, peripheral facial palsy affecting an entire side of the face without limb symptoms can begin Korean medicine treatment immediately from the acute phase.

In Bell's palsy, oral steroid therapy within 72 hours of onset and eye protection are clinically recommended. If the eye does not close fully, artificial tears, eye ointment, and nighttime eye patches are necessary. In Ramsay Hunt syndrome—where vesicles, severe otalgia, hearing loss, or dizziness occur—antiviral therapy must not be delayed. (AAO-HNSF)

Korean medicine care does not wait for acute medical treatment to finish before starting. From the very onset, we evaluate tenderness behind the ear, in the face, jaw, and upper cervical spine, assessing heat, edema, sleep, and systemic status to prescribe acupuncture, pharmacopuncture, and constitution herbal medicine.

In the acute stage, rather than aggressively stimulating paralyzed facial muscles, we focus on reducing perineural inflammation, compression, and accumulated tension behind the ear, jaw, and neck. Herbal prescriptions are customized depending on whether inflammatory heat or fatigue and cold deficiency predominate.

As acute inflammation subsides, forehead wrinkling, eye closure, cheek tone, lip puckering, and smile elevation begin to recover gradually. SOIAN Korean Medicine Clinic divides treatments across forehead, eye, cheek, and perioral zones rather than overstimulating the entire face at once.

Acupuncture and pharmacopuncture relieve retroauricular-facial tenderness and jaw/neck tension, delivering stage-appropriate stimulation to hypoactive muscles. Constitution acupuncture and herbal medicine treat facial heat and swelling while restoring shallow sleep, compromised digestion, and depleted vitality.

Forcefully exaggerating expressions or repetitively straining paralyzed muscles can provoke unwanted aberrant facial tension. We monitor post-treatment eye and mouth mobility, guiding patients to gently practice only necessary movements.

During facial nerve regeneration, facial synkinesis may develop—such as the mouth twitching when closing the eye, or the eye narrowing and cheek/jaw tightening when smiling. This occurs when misdirected nerve fibers consolidate aberrant pathways or persistent hypertonicity remains in facial muscles.

At this stage, rather than merely increasing movement excursion, releasing shortened and contractured muscles and dissociating eye, mouth, and forehead movements is crucial. Acupuncture and pharmacopuncture reduce facial tightness and contracture, while constitution herbal medicine supports neural recovery, fatigue, and sleep.

For patients who clench their jaw, have rigid asymmetric facial/neck tension, and show marked reduction in eye and mouth tightness upon TMJ balancing, we apply TMJ balance therapy. This stabilizes trigeminal sensory inputs, down-regulating hyperactive tension across facial neural circuits.

Even long after onset, facial tightness, spasms, synkinesis, and jaw/neck tension remain treatable. Rather than passively waiting for immobile areas, we actively train remaining functions to move with natural fluidity.

Progress is measured by how comfortably the eye closes, reductions in fluid leakage during drinking and eating, and natural articulation and expression. We also track facial pulling, spasms, degree of synkinesis, and retroauricular or jaw/neck pain.

Initially we verify whether subtle movement returns, subsequently confirming whether that movement sustains without excessive strain. Monitoring the longevity of immediate post-treatment improvements guides the balance of acupuncture, pharmacopuncture, herbal medicine, and TMJ balance therapy.

Because facial palsy has an acute onset, understanding your baseline constitution, cold/heat tendencies, sleep, digestion, and past herbal responses allows faster precision prescribing in early stages. This aligns with the preventive principle of treating sub-health states before full disease manifestation.
