Its presence may increase the likelihood of good facial nerve outcome and hearing preservation after microsurgical resection. A systematic review of the literature was performed. Studies that reported the association of a fundal fluid cap with postoperative outcomes including facial nerve outcome, hearing preservation and extent of resection were included. A total of 17 studies were included, comprising 2370 patients. Studies were generally at high risk of bias. The presence of a fundal cap was associated with significantly higher rate of good (HB I-II) facial nerve outcome after retrosigmoid approaches (OR 6.04; 95%CI 2.79-13.11), but not after translabyrinthine and middle fossa approaches. A fundal cap was associated with an increased rate of gross total resection (OR 2.13; CI: 1.51-3.00) and hearing preservation after retrosigmoid (OR 3.37; 95% CI: 2.32-4.90), but not middle fossa approaches (OR 1.47; 95% CI: 0.89-2.44). A fundal cap was also predictive of hearing preservation after radiosurgery. The fundal CSF cap is an important predictor of facial nerve function and hearing preservation after retrosigmoid craniotomy for vestibular schwannoma. Its importance in middle fossa and translabyrinthine surgery is less clear, which reflects the anatomical considerations of each approach. The presence or absence of a fundal cap should be documented preoperatively and used to guide more nuanced risk assessment for preoperative patient counselling.</p>","PeriodicalId":19184,"journal":{"name":"Neurosurgical Review","volume":"49 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13134987/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147818256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the present work is to provide a systematic review and meta-analysis comparing the safety and efficiency of sequesterectomy and discectomy in the management of lumbar disk herniation. A systematic review and meta-analysis using the random effects method was performed. This search was applied through the 6th of March 2025 to PubMed, Scopus, Cochrane Central Register of Controlled Trials and the Directory of Open Access Journals. The data collected included patient demographics, spinal level at which the operation occurred, duration of operation and hospital stay, outcome, recurrence rate as well as potential immediate and delayed complications. A total of 18 original studies with a cumulative number of 4394 patients were identified. No statistically significant difference was found in the re-herniation and complication rate between the two groups (OR: 1.058, 95% CI: 0.726-1.541, p=.769 and OR: 1.399, 95% CI: 0.964-2.032, p=.077 respectively). The same applied for mean hospital stay (standard difference in means: 0.206, SE = 0.167, p= .219). In contrast, mean operating time was found to be significantly shorter in the sequesterectomy group than in the discectomy group (mean 58.086 min versus 72.885 min respectively). As or the patient reported outcomes, VAS score for back pain two years after the operation was the only index that was significantly higher in patients with discectomy (standard difference in means: 0.348, SE = 0.172, p= .04). Based on the available data, the two approaches do not differ in terms of risk of reherniation, reoperation rate and postoperative complications. Nevertheless, patients that have undergone sequesterectomy could potentially benefit from a more significant reduction in back pain in the long run.</p>","PeriodicalId":19184,"journal":{"name":"Neurosurgical Review","volume":"49 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147818271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep brain stimulation (DBS) has emerged as a potential neurosurgical intervention targeting dysfunctional cortico-striato-limbic circuitry. However, technical heterogeneity and limited clinical data constrain interpretation of outcomes. This systematic review was conducted in accordance with PRISMA guidelines and prospectively registered in PROSPERO (CRD420251080715). Seven electronic databases were searched from inception through January 31, 2025. Clinical studies investigating DBS in TRS or CRS were included. Methodological quality was assessed using Joanna Briggs Institute (JBI) tools. Data extraction emphasized stereotactic targeting methods, hardware configurations, stimulation parameters, and clinical outcomes. The total number of study is 6. We excluded paper by Manssuer 2023. The total study population comprises 21 patients. Seven studies involving 21 patients met inclusion criteria. Targets included the nucleus accumbens (NAcc; n = 11), substantia nigra (SNr; n = 1), habenula (HB; n = 2), subgenual cingulate (SCG; n = 4), subgenual anterior cingulate cortex (sgACC; n = 3). Reported PANSS total score changes ranged widely (11%-85.7%), reflecting substantial inter-individual variability and methodological limitations. Surgical complications occurred in 3 of 21 patients (14.2%), including infection and hemorrhage. All cases utilized open-loop stimulation and conventional cylindrical leads. Current evidence suggests a preliminary therapeutic signal for DBS in highly selected CRS patients, particularly with NAcc targeting. However, conclusions remain limited by small sample sizes, technical heterogeneity, and absence of controlled trials. Future investigations should prioritize standardized stereotactic reporting, volumetric lead reconstruction, and long-term safety assessment within specialized neurosurgical research settings.
