The middle temporal artery (MTA) is the proximal medial branch of the superficial temporal artery (STA), supplying the temporalis muscle along with deep temporal arteries. Its use in vascularized flaps for reconstructive and otologic procedures has been described, yet its potential use in neurosurgery has not been studied. We report a novel technique for exposing the MTA and evaluated its characteristics for extracranial-intracranial cerebrovascular bypass. ⋯ MTA can be safely harvested with an anterolateral approach, following its horizontal portion at the level of the zygomatic root, which is constant. The length and caliber of MTA makes it a potential alternative donor vessel or interposition graft for extracranial-intracranial bypass, especially when other donors are unavailable.

Comparative Study
Deep Brain Stimulation for Essential Tremor: A Comparison of Targets.
Deep brain stimulation (DBS) is an established treatment for refractory essential tremor (ET). Initially, the target of choice was the thalamic ventralis intermedius nucleus (VIM). However, the zona incerta (ZI) has been suggested as a superior target. Both targets are considered safe and effective, but a direct comparison between these targets is lacking. ⋯ In this study, ZI DBS was superior to VIM DBS in terms of patient-reported effectiveness. There was a comparable number of complications between both targets. This finding further supports ZI over VIM as the principal DBS target in essential tremor.

We sought to describe the novel technique and report the outcomes of cervical spondylotic radiculopathy caused by facet joint hyperplasia treated with minimally invasive surgery by laminar and lateral mass screw cofixations. ⋯ Minimally invasive surgery by lamina and lateral mass screw cofixation is safe and effective for the treatment of cervical spondylotic radiculopathy caused by facet joint hyperplasia. In addition to sufficient decompression, this technique provides relative stability to the cervical spine.

A retrospective study was conducted to clarify the risk factors of postoperative sacroiliac joint pain (SIJP) for posterior open lumbar surgery. ⋯ Lumbar fusion surgery and multiple operative segments are interdependent risk factors for the postoperative SIJP. The incidence of postoperative SIJP also increases in patients with lumbar stenosis compared with lumbar disk herniation and lumbar spondylolisthesis.

Although repeat microvascular decompression (MVD) for hemifacial spasm (HFS) in patients with failed prior MVD is potentially curative, little is known about the long-term results of repeat MVD. We aimed to evaluate the long-term outcomes and complications after repeat MVD for HFS. ⋯ Repeat MVD provides lasting relief for most patients with persistent or recurrent HFS, albeit with a relatively high complication rate.
