Six patients noted facial asymmetry after botulinum toxin injection for hemifacial spasm. Each patient was injected on the side contralateral to the spasms with 10 to 15 IU over the zygomatic major and minor muscles. Each patient noted improvement in facial symmetry in the resting position and dynamic facial movements. Five of the six patients desired this approach with subsequent injections. This injection method variation proved helpful in the managing of hemifacial weakness created by botulinum A toxin for this condition.
6例患者在注射肉毒杆菌毒素治疗半面痉挛后出现面部不对称。每位患者均在痉挛对侧的颧大肌和颧小肌上注射10至15国际单位的肉毒杆菌毒素。每位患者均指出，静息位和动态面部运动时的面部对称性有所改善。6例患者中有5例希望在后续注射时采用这种方法。事实证明，这种注射方法的改变有助于处理肉毒杆菌A毒素为此病造成的半面肌无力。
