Facial paralysis: day 3 and month 3 call for different approaches
Male, 45. Onset 3 days ago, left side, with retroauricular pain and reduced taste.
One disease name, three phases: in the acute phase the watchwords are light, early, steady; in recovery, tonify, unblock, train; in the sequelae stage, the realistic limits of recovery must be stated honestly. Staging is the core of a Bell's palsy case.
History and prior work-up
Three days ago, on waking, left-sided deviation of the mouth, incomplete eye closure, and loss of the forehead crease were noticed; there had been exposure to cold one week before onset. No limb weakness, slurred speech, or double vision — central causes were excluded.
Peripheral facial paralysis (Bell's palsy) had been diagnosed at neurology, with a full course of corticosteroid (prednisone) and antiviral (acyclovir) treatment; no diabetes or hypertension; EMG not yet performed.
Examination and pattern differentiation
Pattern: in the acute phase, wind-cold attacking the collaterals; in the recovery phase, usually qi-blood insufficiency with blood stasis obstructing the collaterals. The key points are the trigger before onset, facial sensation, the tongue and pulse, and accompanying general symptoms. The textbook maps this to kou pi (peripheral facial paralysis) in its wind-cold, wind-heat, and qi-blood deficiency patterns.
- Left forehead crease gone, eye closure incomplete, air leaking when puffing the cheeks, mouth deviated to the healthy side; tenderness behind the left ear.
- Tongue pale red with a thin white coat; pulse floating and tight; exposure to cold before onset (wind-cold exterior pattern); sleep fair.
Treatment pathway (staged care is the core)
- Acute phase (first 1–2 weeks): gentle stimulation, early intervention, few points — Yangbai GB14, Sibai ST2, Dicang ST4, Jiache ST6, Yifeng TE17, Hegu LI4, Waiguan TE5; superficial needling with light twirling, no electroacupuncture or only very low intensity; gentle moxibustion at Yifeng and Tinggong. Strong stimulation is avoided in this phase; twice to three times weekly.
- Recovery phase (after 2 weeks): more points and stronger stimulation; electroacupuncture may be used (discontinuous wave, within the patient's tolerance), adding Zusanli ST36 and Sanyinjiao SP6 to boost qi and blood; paired with facial functional training (puffing the cheeks, frowning, baring the teeth, inflating the mouth with air).
- Sequelae stage (beyond 3 months): tonify qi and blood, invigorate the collaterals, with tuina and facial muscle re-education; the goal shifts to functional improvement and controlling synkinesis, with the limited scope of recovery stated honestly.
- Herbal direction: for wind-cold, the intent of Qianzheng Powder (powder to dispel wind and correct the face) combined with Guizhi Decoction; for wind-heat, Yinqiao Powder with modifications; in the recovery phase, Buyang Huanwu Decoction or Bazhen Decoction (Eight-Gem) with modifications. Dosage is set at the in-person consultation.
Re-evaluation
| Timepoint | Eye closure | Forehead crease | Cheek puffing | Mouth deviation (self-rated) | Synkinesis |
|---|---|---|---|---|---|
| First visit | Incomplete (3 mm of sclera showing) | Gone | Obvious air leak | Marked | None |
| Week 4 | Closes nearly fully | Partially recovered | Slight leak | Reduced | None |
| Week 12 | Full closure | Recovered | Normal | Nearly symmetric | Mild |
Follow-up and advice
Recovery from facial nerve palsy usually takes weeks to months; in the acute phase, neurology must first exclude central lesions and complete standard drug treatment. With incomplete eye closure, nightly eye protection is required (artificial tears, ointment, an eye shield) to prevent corneal injury.
