The purpose of this study is to explore the clinical efficacy of intradermal acupuncture in the treatment of ocular surface diseases after Intractable Facial Paralysis, and to seek effective and convenient treatment for ocular surface diseases after intractable peripheral facial paralysis. The main question it aims to answer is ： Will the intradermal acupuncture intervention effectively reduce the OSDI score ? The researchers compared the intradermal acupuncture with the placebo-needle to observe whether the intradermal acupuncture could better improve the symptoms.

2.Meets diagnostic criteria for intractable peripheral facial paralysis, with disease duration from 1 month to 1 year. FNGS 2.0 ≥15 points; ENoG shows the ratio of CMAP amplitude≤ 20%.
3.At least one subjective ocular symptom (dryness, foreign body sensation, burning, fatigue, redness, fluctuating vision) and OSDI scores between 30 and 80.
4.Voluntarily provides written informed consent and can comply with treatment and follow-up.
