First bite syndrome (FBS) is an uncommon pain syndrome characterised by severe cramping or spasm in the parotid region with the first bite of each meal. The proposed pathogenesis is sympathetic denervation of the parotid gland secondary to iatrogenic injury with resultant cross-stimulatory parasympathetic hypersensitivity response. FBS is a potential sequela of surgeries involving the infratemporal fossa, parapharyngeal space and/or deep lobe of the parotid gland, however, only four cases of FBS secondary to carotid endarterectomy have been documented to date. We present a case and management of a 77-year-old man who developed FBS after an ipsilateral carotid endarterectomy, to raise awareness of this complication among surgeons who operate in the neck region.
首咬综合征(FBS)是一种罕见的疼痛综合征,其特征为每餐首次咬合时腮腺区域出现严重绞痛或痉挛。其发病机制推测是医源性损伤继发腮腺交感神经去神经支配,导致交叉刺激性副交感神经超敏反应。FBS是涉及颞下窝、咽旁间隙和/或腮腺深叶手术的潜在后遗症,然而,迄今为止,仅有4例颈动脉内膜剥脱术后继发FBS的病例被记录。我们报告一例77岁男性在同侧颈动脉内膜剥脱术后发生FBS的病例及处理情况,以提高在颈部手术的外科医生对该并发症的认识。
