Absolute ethanol sclerotherapy provides a reliable treatment for facial venous malformation, although facial nerve injury may occur after sclerotherapy. This study is a retrospective review of facial nerve dysfunction after sclerotherapy.
A total of 91 patients with facial venous malformations accepted 288 ethanol sclerotherapy sessions. The facial nerve dysfunctions caused by the therapy were evaluated and analyzed.
There were 9 instances of facial nerve injury. For 18 sessions of sclerotherapy in the temporal region, 5.6% of patients experienced injury to the temporal branch; for 12 sessions in the zygomatic region, 41.7% of patients experienced injury to the zygomatic branch. After patients were treated with medication, 8 of 9 instances of nerve injury recovered.
The zygomatic and temporal branches of the facial nerve were the most vulnerable to injury after ethanol sclerotherapy. Surgeons are thus called on to pay more attention when performing ethanol sclerotherapy in those areas.
绝对乙醇硬化疗法为治疗面部静脉畸形提供了一种可靠的方法，但硬化疗法后可能会发生面神经损伤。本研究回顾性分析了硬化疗法后面神经功能障碍的情况。
共 91 例面部静脉畸形患者接受了 288 次乙醇硬化疗法。评估和分析了治疗引起的面神经功能障碍。
共发生 9 例面神经损伤。颞区 18 次硬化治疗中，5.6%的患者出现颞支损伤；颧区 12 次治疗中，41.7%的患者出现颧支损伤。患者接受药物治疗后，9 例神经损伤中有 8 例恢复。
乙醇硬化疗法后面神经的颧支和颞支最容易受损。因此，外科医生在这些区域进行乙醇硬化治疗时应更加注意。
