Microvascular is a safe and effective therapeutic intervention for hemifacial spasm; however, its potential association with hearing impairment remains a concern. This study aimed to determine the prevalence, patterns, and risk factors of hearing loss following microvascular decompression in patients with hemifacial spasm. In accordance with PRISMA guidelines, a systematic literature search was conducted across PubMed, Cochrane Library, ScienceDirect, and Web of Science from inception to April 2025. Eligible studies included adult patients undergoing microvascular decompression for hemifacial spasm with preoperative and postoperative objective hearing assessments. Data on hearing outcomes and potential risk factors (e.g., brainstem auditory evoked response, cerebellar manipulation, and compressing vessels) were extracted. Meta-analysis was performed using a random-effects model, and meta-regression was used to explore potential moderators. Eleven studies (N = 4,014) met the inclusion criteria. The pooled prevalence of permanent postoperative hearing loss was 2.60
Mucopolysaccharidoses (MPS) represent a group of rare inherited lysosomal storage disorders, of which neurosurgical issues arise during childhood and adolescence. The literature however remains fragmented in terms of these specific outcomes. Correspondingly, we sought to synthesize a primer for neurosurgeons in regard to MPS, summarizing the neurosurgical manifestations and management reported in the contemporary literature. A systematic interrogation of the literature was performed according to PRISMA guidelines. Electronic databases were searched from inception through June 2026. Studies reporting hydrocephalus, craniovertebral junction (CVJ) abnormalities, spinal cord compression, myelopathy, spinal deformity, neurosurgical interventions, or related outcomes in patients with any MPS subtype were included and their findings aggregated. Seventy-eight studies comprising 983 patients with 37.8
The parietal lobe is a highly interconnected cortical hub involved in language, sensory integration, visuospatial processing, and cognition. Although neurological and cognitive consequences of parietal tumors have previously been described, detailed preoperative neuropsychological profiles obtained using comprehensive assessment batteries remain incompletely documented. This study aimed to describe preoperative neuropsychological impairments in adults with parietal glial and glioneuronal tumors and to explore descriptive patterns according to hemispheric laterality and parietal subregion. A retrospective two-center study was conducted over a 20-year period. Adult patients with newly diagnosed parietal glial or glioneuronal tumors who underwent comprehensive preoperative neuropsychological evaluation within 15 days of tumor diagnosis were included. Tumor locations were classified according to their laterality and anatomical subregions: postcentral gyrus, superior parietal lobule, supramarginal gyrus, angular gyrus, and precuneus. Forty-six predominantly right-handed patients were included; WHO grade 2 oligodendroglioma was the most common subtype (45.6
Purpose to comprehensively identify determining factors of perceived neck pain in a non-deformity population, integrating psychological and sagittal balance parameters. Methods a cross-sectional study of prospectively collected data was conducted on patients admitted for cervical spondylosis at two tertiary university hospitals between April 2024 and August 2025. Eligible cases were retrieved from the PANDA Registry. Records were excluded if standing X-ray was unavailable and/or not-evaluable (e.g. shoulder prosthesis); or if the admission pathology involved the cranio-cervical junction, tumors, deformities, spinal cord disease, or infections. Preoperative data included demographic, clinical (VAS neck), psychological (SCL-27, I-TIPI, CD-RISC10), and sagittal balance variables (McGregor slope, C1–C2 lordosis, C2 slope, C2–C7 lordosis, cSVA, T1 slope, cervical mismatch). Correction for multiple comparisons was applied within pre-specified hypothesis domains. Results one-hundred-thirty records were included. Intra-rater reliability for radiographic parameters was excellent (> 0.9). After categorization of patients by neck pain severity, pairwise analysis showed that only C1–C2 lordosis remained significantly higher in patients exhibiting severe neck pain (VAS < 7 vs. VAS ≥ 7). When stratified for moderate-to-severe neck pain (VAS ≥ 4), several SCL-27 scales, namely dysthymic, vegetative, agoraphobic, sociophobic, and GSI scores, and C1C2 lordosis showed significant differences. Correlation analysis using VAS neck as the dependent variable demonstrated a significant positive correlation with SCL-27 dysthymic and vegetative scores. C1–C2 lordosis showed a significant inverse correlation with neck pain. In univariate analysis, only SCL-27 dysthymic, vegetative, and GSI scores emerged as significant univariate associations of VAS neck. After correction for multiple comparisons, the SCL-27 vegetative, dysthymic and GSI scores retained significance, whereas C1–C2 lordosis did not. Conclusion in a non-deformity population, sagittal balance parameters alone do not adequately explain patient-perceived neck pain. These findings support the preoperative use of psychological assessments, especially the SCL-27, as a useful tool in preoperative screening and individualised counselling.
Ventricular catheter placement (VCP) is a life-saving intervention frequently performed in emergency departments and intensive care units. The free hand technique is the most commonly used approach for placing catheters. This study demonstrates the anatomical and radiological relationship between catheters inserted through the most commonly used access points and the anatomical structures in their path. Moreover, we calculate the insertion angles and catheter lengths that should be specified during VCP. Six donated human heads, fixed in 10
