The best period for acupuncture for facial palsy is from day 8 to within 3 months. The development of facial palsy occurs through four stages. The first day of onset is the progressive phase, i.e. the inflammatory edema phase, the 8th-15th day is the plateau phase, the 16th day to 3 months is the recovery phase, and more than 3 months is the posterior phase. The best time to treat clinical interventions with acupuncture, especially facial acupuncture, is from day 8 to within 3 months. The first period belongs to the progressive period, inflammatory edema period, if interventional acupuncture will aggravate edema, so generally choose day 8 to 3 months as the best acupuncture interventional treatment time. more than 3 months is the sequelae period, treatment is not effective, more than six months more difficult, will appear facial nerve degeneration.
