Facial nerve palsy is a rare but known complication of dental local anaesthesia and may be underreported. We describe a case of a transient facial nerve palsy following the administration of an inferior alveolar nerve block and discuss the immediate practical management. Knowing the likely transient nature of this complication means the patient can be reassured and unnecessary referral avoided. While the blink reflex is inhibited, steps are needed in order to protect the cornea and prevent secondary infection and scarring.
面神经麻痹是牙科局部麻醉的一种罕见但已知的并发症，可能报告不足。我们描述了一例在下颌神经阻滞给药后出现短暂性面神经麻痹的病例，并讨论了即时的实际处理方法。了解这种并发症可能是暂时的，这意味着可以让患者安心并避免不必要的转介。虽然眨眼反射受到抑制，但需要采取措施保护角膜，防止继发感染和瘢痕形成。
