Deep brain stimulation of the subthalamic nucleus for primary Meige syndrome: clinical outcomes and predictive factors.
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has demonstrated efficacy against multiple types of dystonia, but only a few case reports and small-sample studies have investigated the clinical utility of STN-DBS for Meige syndrome, a rare but distressing form of craniofacial dystonia. Furthermore, the effects of DBS on critical neuropsychological sequelae, such as depression and anxiety, are rarely examined. In this study, the authors investigated the therapeutic efficacy of STN-DBS for both motor and psychiatric symptoms of Meige syndrome. ⋯ These findings support STN-DBS as an effective and promising therapy for both motor and nonmotor symptoms of Meige syndrome. Timely diagnosis, treatment of preoperative anxiety, and precise electrode placement within the dorsolateral STN are essential for optimal clinical outcome.

Long-term tumor control in Koos grade IV vestibular schwannomas without the need for gross-total resection.
The modern management of patients with Koos grade IV vestibular schwannomas (VSs) aims at functional preservation and long-term tumor control. Gross-total resection (GTR) leads to optimal tumor control but frequently also results in permanent facial nerve (FN) palsy. Subtotal resection (STR) or near-total resection (NTR) followed by a wait-and-scan protocol and second-line radiation therapy (RT) in case of progressive residuals yields excellent tumor control rates with less permanent morbidity. ⋯ STR followed by observation and second-line RT in cases of progression leads to good facial outcome and an excellent tumor control rate in the longer term.

A novel radiological classification of midbrain pilocytic astrocytomas and its implication for surgical management: a single-institution experience of 57 cases.
Surgery for midbrain pilocytic astrocytoma (PA) remains a formidable challenge. To facilitate decision-making and achieve a better outcome in the management of patients with midbrain PA, the authors have proposed a novel radiological classification of midbrain PAs with long-term follow-up. ⋯ A novel and comprehensive radiological classification of midbrain PAs was established, which will serve as a valuable tool in patient management and promote uniform communication and comparison across different studies and publications.

Performance of ear canal sound measurements in detecting dural arteriovenous fistulas.
Patients with pulsatile tinnitus (PT) are often referred for digital subtraction angiography (DSA) to exclude cranial dural arteriovenous fistula (DAVF). Because DSA is not without risk, the authors studied the sensitivity and specificity of an automated detection algorithm that analyses external ear canal sound measurements to evaluate the presence of DAVF in PT patients. ⋯ Analysis of external ear canal sound measurements in PT patients showed 100% sensitivity for detecting DAVF on DSA. This analysis can potentially be used as a screening tool to help clinicians and PT patients to decide on the necessity of DSA. Retrospectively, the use of sound measurement in our cohort would have narrowed the indication for DSA to 23 of 49 cases (47%) without missing a DAVF.

Observational StudySame-day discharge after craniotomy for tumor resection: a retrospective observational single-center study of 630 patients.
Modern neurosurgical developments enable minimally invasive surgery with shorter operation times, faster recovery, and earlier hospital discharge. These in combination with Enhanced Recovery After Surgery (ERAS) protocols have the potential to safely shift craniotomy for tumor resection to the ambulatory setting in selected patients. The aim of this retrospective observational single-center study was to assess the success rate of planned same-day discharge from hospital in patients undergoing craniotomy for supratentorial brain tumor resection under general anesthesia or awake craniotomy as well as to explore potential associations with anesthesia techniques, complications, and readmission rates. ⋯ This retrospective, single-center analysis shows that same-day discharge after craniotomy can be safe in carefully selected patients after both GA and AC for tumor resection. Multidisciplinary involvement (surgeons, anesthesiologists, nurses, and other allied health professionals) optimizes success of same-day craniotomy programs. Future optimization of analgesia and prevention of PONV has the potential to increase the success rate.
