To describe 4 patients who sustained facial nerve injury during temporal artery biopsy.
Retrospective, observational case series.
The medical records were reviewed of 4 patients (2 men, 2 women; mean age 72.8 years, range 60 to 87), referred for evaluation of palsy of the frontal branch of the facial nerve following temporal artery biopsy. Main outcomes measured were site of incision, length of follow-up, and degree of recovery.
In all cases, incisions were made in the preauricular region or on the pretrichial temple within 3 cm of the lateral canthal angle. Follow-up ranged from 1 month to over 5 years. No patient recovered completely; 2 had partial return of function, and 2 reported no improvement.
Branch facial nerve palsy can occur with temporal artery biopsy and is likely to result in permanent disability. In all cases the incision was placed within the known course of the frontal branch of the facial nerve. To prevent this rare complication, we advocate biopsy of the parietal, rather than the frontal, branch of the superficial temporal artery.
描述 4 例在颞动脉活检过程中发生面神经损伤的患者。
回顾性、观察性病例系列研究。
回顾性分析了 4 例（2 男 2 女；平均年龄 72.8 岁，范围 60 至 87 岁）因颞动脉活检后面神经额支瘫痪而就诊的患者的病历。主要观察指标为切口部位、随访时间和恢复程度。
所有病例的切口均位于耳前区或外眦角 3cm 内的颞区。随访时间从 1 个月到 5 年以上。没有患者完全恢复；2 例部分恢复功能，2 例无改善。
颞动脉活检可导致分支面神经瘫痪，并可能导致永久性残疾。所有病例的切口均位于已知的面神经额支走行部位内。为了预防这种罕见的并发症，我们提倡对颞浅动脉的顶支而不是额支进行活检。
