近年来对疼痛和各种顽固性疾病也积极开展神经阻滞疗法,且取得良好效果。眼科适合神经阻滞治疗的有面部及眼睑痉挛、面神经麻痹、视网膜中心动脉阻塞、囊状黄斑水肿等。本文介绍面部和眼睑痉挛的治疗。面部痉挛的原因有炎症、压迫和肿瘤等。1977年Jannetta发现面神经在桥脑角部受椎动脉及其分支动脉压迫而发生刺激症状—面部痉挛。将压迫动脉游离,实行所谓面神经减压术后,获得满意效果。此外也有少数病例可由肿瘤或静脉压迫所致。鉴于面神经减压术乃需长时间的脑外科显微手术,有可能引起严重合并症,故对患者思想负担较重。因此,作者采用面神经穿
In recent years, pain and various intractable diseases also actively carry out nerve block therapy, and achieved good results. Ophthalmology for nerve block treatment of facial and blepharospasm, facial paralysis, central retinal artery occlusion, cystic macular edema and so on. This article describes the treatment of facial and blepharospasm. Causes of facial spasms include inflammation, oppression and cancer. Jannetta in 1977 found that the facial nerve in the pons and corners of the vertebral artery and its branch artery oppression and irritation - facial spasms. The oppressed artery free, the implementation of the so-called facial nerve decompression surgery, to obtain satisfactory results. In addition there are a few cases can be caused by tumor or vein compression. In view of facial nerve decompression is the need for a long time surgical microsurgery, may cause serious complications, so patients thought heavier burden. Therefore, the author uses facial nerve wear
