Sixteen patients with hemifacial spasm were treated by posterior fossa surgery and wrapping of sponge around their facial nerve. A good or excellent result has been obtained in fourteen of the sixteen cases, and in seven cases followed by four years or longer. Two patients had a mild recurrence of their hemifacial spasm after a cessation of their spasm for eighteen months and two years following surgery. Contrary to the experience of other authors a definite vascular abnormality was found in only four cases. In the other twelve cases circumferential fibrosis about the nerve is again proposed as a mechanism for the effectiveness of the procedure.
16例面肌痉挛患者接受了后颅窝手术并在面神经周围包裹海绵。16例中有14例取得了良好或优异的效果,其中7例随访了4年或更长时间。2例患者在术后痉挛停止18个月和2年后面肌痉挛出现轻度复发。与其他作者的经验相反,仅在4例中发现明确的血管异常。在其他12例中,再次提出神经周围的环状纤维化是该手术有效的机制。
