要約　目的：ボツリヌスA毒素の注射前に，局所冷却をリドカインテープ貼付に併用したときの鎮痛効果の報告。対象と方法：眼瞼けいれんに対してボツリヌスA毒素注射を行った9例を対象とした。全例が女性で，年齢は49～78歳（平均66歳）である。両眼のボツリヌスA毒素の注射予定部位にリドカインテープを30分間貼り，続いて片眼のみにアイスパックを2分間当てて冷却した。注射時の痛みを11段階で評価した。結果：主観的な痛みは，リドカインテープ単独では6.9，局所冷却を併用した側では2.8であり，59.4％の鎮痛軽減効果があった（p＝0.0003）。結論：ボツリヌスA毒素注射時に行うリドカインテープ貼付に局所冷却を併用すると，相乗的な鎮痛効果が得られる。
