We report here the case of four patients presenting with delayed-onset temporal pain after pterional craniotomy. They reported similar symptoms: attacks of pain over the temporal region, ipsilateral to the operative site, irradiating around the eye and lasting from 10 min to 1 h. All patients had hypertrophy of at least one part of the temporalis muscle. All responded dramatically to botulinum toxin A injection (25 to 50 Botox® units) into the temporalis muscle. We suggest that the headaches were caused by aberrant nerve regeneration following surgical injury to the frontal branch of the facial nerve.
我们在此报告4例翼点入路开颅术后出现迟发性颞部疼痛的病例。他们报告了相似的症状：手术部位同侧颞部区域发作性疼痛，向眼周放射，持续10分钟至1小时。所有患者颞肌至少有一部分肥厚。所有患者经颞肌注射A型肉毒毒素（25至50单位保妥适®）后均有显著疗效。我们认为，这些头痛是由于面神经额支手术损伤后异常神经再生所致。
