Abstract：Objective To investigate the surgical treatment of hemifacial spasm caused by vertebrobasilar dolichoectasia(VBD). Methods The clinical data of 7 patients with hemifacial spasm caused by the VBD,who were treated in our hospital from July,2014 to July, 2017, were analyzed resprectively, incluindg preoperative MRI findings, microvascular decompression data and postoperative following-up outcomes. Results Of 7 patients with VBD revealed by preoperative MRI, 3 were treated by the routine microvascular decompression and 4 by"the double-side glue suspension technique",i.e.sticking the offending artery to petrous bone dura in order to keep it away from the facial nerve root exit zone. The hemifacial spasm disappeared completely in 6 patients and there was residual partial facial spasm in 1,but 2 patients had transient facial paralysis after the surgery.Conclusions The surgical treatment of hemifacial spasm caused by VBD is difficult and may cause many complications.The"double-side glue suspension technique",which is a simple and easily practicable technique,can enhance curative effect of surgery on the hemifacial spasm caused by VBD.
