1. 手術前準備 設置 在注射肉毒桿菌前準備患者及皮膚。
- 徹底清潔眼周皮膚
- 塗抹外用麻醉膏 20–30 分鐘以減輕不適
- 在外眥處標記注射點，針對魚尾紋放射區域
2. 劑量與稀釋 建議 確定魚尾紋的適當肉毒桿菌劑量。
- 常用劑量：每側 6–15 單位
- 用無防腐劑生理鹽水稀釋（標準稀釋：100 單位加 2.0–2.5 mL）
- 使用 30–32 號細針以提高精準度
3. 注射技術 關鍵 將肉毒桿菌注射至正確的解剖層次。
- 在眼外側注射 3–4 個點
- 深度：皮內至淺層肌肉（針對眼輪匝肌纖維）
- 角度：肌肉內注射 90°，皮下注射 45°
- 避免擴散至顴大肌，以保持笑容對稱
4. 注射後即時護理 減少瘀青並確保患者舒適。
- 對注射點輕壓 1–2 分鐘
- 必要時使用冷敷以減輕腫脹
- 不要按摩或揉搓治療區域
5. 術後指導 安全 提醒患者治療後需避免的活動。
- 24 小時內避免劇烈運動
- 4–6 小時內避免平躺或過度彎曲
- 當日避免飲酒
- 24–48 小時內避免桑拿、熱水浴或高溫環境
- 監測可能的副作用，如瘀青或不對稱
✨ 總結：魚尾紋的肉毒桿菌治療包括仔細的術前準備、精準劑量（每側 6–15 單位）、在外眥處皮內或淺層肌肉注射。妥善的術後護理——如避免運動、飲酒及高溫暴露——可確保最佳美容效果並減少併發症。
1
Pre‑operative Preparation
Setup
Prepare the patient and skin before Botox injection.
- Cleanse the periocular skin thoroughly
- Apply topical numbing cream for 20–30 minutes to reduce discomfort
- Mark injection sites along the lateral canthus where crow’s feet wrinkles radiate
2
Dosage and Dilution
Recommended
Determine the appropriate Botox dose for crow’s feet.
- Typical dose: 6–15 units per side
- Dilute Botox with preservative‑free saline (standard dilution 2.0–2.5 mL per 100 units)
- Use a 30–32 gauge fine needle for precision
3
Injection Technique
Critical
Deliver Botox into the correct anatomical level.
- Inject at 3–4 points lateral to the eye
- Depth: intradermal to superficial intramuscular (targeting orbicularis oculi fibers)
- Angle: 90° for intramuscular, 45° for subcutaneous placement
- Avoid diffusion into zygomaticus major to preserve smile symmetry
4
Immediate Post‑Injection Care
Minimize bruising and ensure patient comfort.
- Apply gentle pressure to injection sites for 1–2 minutes
- Use cold compress if needed to reduce swelling
- Do not massage or rub treated areas
5
Post‑operative Instructions
Safety
Advise the patient on activities to avoid after treatment.
- Avoid strenuous sports or exercise for 24 hours
- Do not lie flat or bend excessively for 4–6 hours
- Refrain from alcohol consumption on the same day
- Avoid sauna, hot baths, or heat exposure for 24–48 hours
- Monitor for side effects such as bruising or asymmetry

✨ In summary: Botox for crow’s feet involves careful preparation, precise dosing (6–15 units per side), and superficial intradermal/intramuscular injections at the lateral canthus. Proper aftercare—including avoiding exercise, alcohol, and heat exposure—ensures optimal cosmetic results and minimizes complications.
