Linear array ultrasound in low-grade glioma surgery: histology-based assessment of accuracy in comparison to conventional intraoperative ultrasound and intraoperative MRI.
In low-grade glioma (LGG) surgery, intraoperative differentiation between tumor and most likely tumor-free brain tissue can be challenging. Intraoperative ultrasound can facilitate tumor resection. The aim of this study is to evaluate the accuracy of linear array ultrasound in comparison to conventional intraoperative ultrasound (cioUS) and intraoperative high-field MRI (iMRI). ⋯ Intraoperative resection control in LGGs using lioUS reaches a degree of accuracy close to iMRI. Test results of lioUS are superior to cioUS. cioUS often fails to discriminate solid tumors from "normal" brain tissue during resection control. Only in lesions <10 cc cioUS does show good accuracy.

Is duration of surgery a risk factor for extracranial complications and surgical site infections after intracranial tumor operations?
Duration of surgery has not been much explored as a possible risk factor for complications in neurosurgery. ⋯ Duration of surgery together with comorbidity and acquired neurological deficits is an independent risk factor for extracranial complications after brain tumor surgery. Duration of surgery is also associated with surgical site infections. Knowledge about the potential harm of slow surgery should be of interest to neurosurgeons when deciding on various surgical approaches, surgical tools or providing training. Also if acquiring ethical approval or informed consent in technical research projects, the risks associated with prolonging brain surgery should be considered. Special consideration should be warranted in patients with significant comorbidity, planned long surgery and higher risk of acquiring neurological deficits after surgery.

Pure aqueductal tumors (ATs) differ from pineal region and tectal/tegmental tumors in that they are epicentered within the aqueduct. Nevertheless, these tumors are rarely described as a separate type of tumor, and are often grouped with other lesions located in the same vicinity. The present multicenter study focuses on our experience treating patients with pure ATs. ⋯ ATs are a rare entities that usually present with obstructive hydrocephalus. Treatment includes primarily cerebrospinal fluid drainage (preferably via an endoscopic third ventriculostomy). Simultaneous endoscopic biopsy may be done in selected cases. Tumor resection should be reserved for growing tumors; the trans-fourth ventricular or trans-choroidal approaches are probably safer than other approaches used to reach the tectal region.

ReviewVago-glossopharyngeal neuralgia: a literature review of neurosurgical experience.
Glossopharyngeal neuralgia (GPN), or better named vago-glossopharyngeal neuralgia (VGPN), is a rare disorder amounting to 1 % of the incidence of trigeminal neuralgia (TN). Pain is paroxysmal, of the electrical shooting type, and mainly provoked by stimulation of the pharynx or deep throat, especially during swallowing. Due to its rarity, VGPN is often misdiagnosed. ⋯ In patients with precarious general conditions, stereotactic radiosurgery may be considered. Also, thermo-rhizotomy at the pars nervosa of foramen jugularis or tractotomy-nucleotomy at brainstem may be alternatives, but these methods entail a significant risk of deficits. In this article, the authors reviewed the main literature series on neurosurgical treatments of this disease.

Comparative StudyProspective comparison of simple suturing and elevation debridement in compound depressed fractures with no significant mass effect.
Compound depressed fractures have conventionally been managed surgically with elevation and debridement to avoid infection, especially when there is dural penetration, nonetheless with little evidence. This study was to prospectively compare outcomes after simple suturing and elevation debridement in patients with compound depressed fractures. ⋯ Simple suturing seems to be an equally good option in patients with compound depressed fracture with no significant mass effect or brain matter herniation.
