Background: Thoracic schwannomas are benign nerve sheath tumors that can cause neurological and respiratory symptoms depending on their location and extension. The optimal surgical approach remains debated, particularly regarding resection extent, complication rates, and postoperative morbidity. Methods: This retrospective multicenter study analyzed 106 patients treated between 2011 and 2024, classifying tumors according to the Eden system and comparing surgical strategies. Surgical variables, including operative time, blood loss, resection extent, recurrence rates, and complications classified by Clavien–Dindo, were analyzed. Results: Eden I and II schwannomas were treated with laminectomy (LCT) or hemilaminectomy (HLCT) and transpedicular approaches (TPD), achieving high gross total resection (GTR) rates with minimal complications. Eden III dumbbell tumors benefited from a combined neurosurgical–thoracic approach (LCT + VATS), which resulted in higher GTR rates (100% vs. 62%, p < 0.01) and lower dural complications compared to neurosurgical resection alone. Eden IV extraforaminal schwannomas were best managed with VATS, which was associated with lower intraoperative blood loss (p = 0.018), shorter surgical duration (p = 0.027), and reduced postoperative complications compared to open thoracotomy. Our findings confirm that minimally invasive techniques, particularly VATS and combined neurosurgical–thoracic approaches, optimize tumor resection while reducing morbidity. However, feasibility depends on institutional resources and multidisciplinary collaboration. Conclusions: This study provides a stratified comparison of surgical approaches tailored to Eden classification, aiming to identify the most effective and least morbid strategies for each lesion type. Future prospective studies should validate these findings, integrating preoperative functional assessments and long-term follow-up to better stratify surgical risk, personalize operative planning, and refine surgical decision making for thoracic schwannomas.

Background: The neurosurgical treatment of thoracic disc herniation (TDH) has undergone dramatic changes over the years in terms of surgical approaches and intraoperative technological tools. There is still no unanimous consent on the criteria for approach selection, and the choice varies among Institutions. The aim of this study is to compare anterior and posterolateral approaches for TDH in terms of functional and surgical outcomes. Methods: A systematic literature review and meta-analysis according to PRISMA guidelines from EMBASE, PubMed, Cochrane Library, Web of Science, and Google Scholar online databases up to May 2024 incorporated studies that reported outcomes of thoracic disc herniation surgeries. Analyzed factors included major peri- and postoperative complications, intraoperative blood loss, hospital stay, neurological improvement, and complete hernia resection. Random-effect models were used to calculate pooled odds ratios and mean differences. Results: The posterolateral approach was associated with significantly lower rates of major medical (OR 0.14, 95% CI: 0.07 to 0.27) and surgical complications (OR 0.61, 95% CI: 0.38 to 0.99) compared to the anterior approach. Additionally, posterolateral approaches reduced intraoperative blood loss and shorter hospital stays. Posterolateral techniques were linked to higher odds of neurological improvement (OR 0.65, 95% CI: 0.43 to 0.99) and higher rates of complete hernia resection (OR 0.38, 95% CI: 0.21 to 0.71). Conclusions: Posterolateral approaches offer advantages in terms of safety, recovery, neurological improvement, and complete hernia resection. More extensive prospective studies are needed to confirm these findings and refine surgical strategies. Emerging technologies, such as the exoscope and 45° endoscopy, may further enhance surgical outcomes.

Background: Although its validity has recently been questioned since its introduction, the Simpson grade has remained one of the most relevant factors in estimating the recurrence risk of intracranial meningiomas. This study aims to assess its role in spinal meningiomas through a retrospective analysis of a mono-institutional surgical series and literature meta-analysis. Methods: We conducted a systematic review and meta-analysis of the literature from 1980 to 2023, complemented by a mono-institutional series of 74 patients treated at “Santa Maria delle Grazie” hospital. Demographic, clinical, neuroradiological, pathological, surgical, and outcome data of case series were analyzed. For the meta-analysis, studies were selected based on predefined inclusion criteria, and a fixed-effects model was used to synthesize data due to assumed homogeneity among included studies. Statistical analyses included odds ratios (OR) for recurrence risk and assessment of publication bias using Peter’s test. Results: Mono-institutional sample included 74 patients, most of whom were women (85%) with a median age of 61.9 years. The thoracic spine was the most common tumor location (81%). Recurrences occurred in patients with Simpson grade II and III resections. The meta-analysis involved 2142 patients from 25 studies and revealed a significantly higher recurrence rate for Simpson grades III–V compared to grades I–II (OR 0.10; CI95 0.06–0.16). Additionally, Simpson grade II had a higher recurrence risk than grade I (OR 0.42; CI95 0.20–0.90). Conclusions: The Simpson grading remains a valid predictor of recurrence also for spinal meningiomas. Our findings revealed a significant increase in recurrence rate with higher Simpson grades. These results support the need to strive for Simpson grade I resection when feasible.

Background: There are several etiologies of craniocervical junction instability (CCJI); trauma, rheumatoid arthritis (RA), infections, tumors, congenital deformity, and degenerative processes. These conditions often require surgery and craniocervical fixation. In rare cases, breakdown of such CCJI fusions (i.e., due to cerebrospinal fluid [CSF] leaks, infection, and wound necrosis) may warrant the utilization of occipital periosteal rescue flaps and scalp rotation flaps to achieve adequate closure. Case Description: A 33-year-old female with RA, cranial settling, and high cervical cord compression underwent an occipitocervical instrumented C0–C3/C4 fusion. Two months later, revision surgery was required due to articular screws pull out, CSF leakage, and infection. At the second surgery, the patient required screws removal, the application of laminar clamps, and sealing the leak with fibrin glue. However, the CSF leak persisted, and the skin edges necrosed leaving the hardware exposed. The third surgery was performed in conjunction with a plastic surgeon. It included operative debridement and covering the instrumentation with a pericranial flap. The resulting cutaneous defect was then additionally reconstructed with a scalp rotation flap. Postoperatively, the patient adequately recovered without sequelae. Conclusion: A 33-year-old female undergoing an occipitocervical fusion developed a postoperative persistent CSF leak, infection, and wound necrosis. This complication warranted the assistance of plastic surgery to attain closure. This required an occipital periosteal rescue flap with an added scalp rotation flap.

Background/Objectives: Degenerative lumbar spinal stenosis (LSS) is a prevalent cause of disability in elderly populations, often treated with decompressive surgery. However, postoperative functional outcomes are variable and influenced by factors beyond neural compression alone. This study aimed to investigate the prognostic significance of the Goutallier Classification System (GS), a radiological index of paravertebral muscle fatty degeneration, in predicting long-term postoperative disability and pain in elderly patients undergoing decompression for LSS. Methods: A retrospective cohort study was conducted on 100 elderly patients who underwent primary lumbar decompression surgery for LSS between January 2020 and July 2022, with a minimum two-year follow-up. Patients were stratified according to their preoperative GS grades assessed via MRI. The Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) for pain were collected preoperatively and at follow-up. Changes in the ODI and VAS (ΔODI and ΔVAS) were analyzed to evaluate associations between GS grades and functional outcomes. Results: Significant improvements in the ODI (from 41.0 ± 17.5 to 16.9 ± 8.2) and VAS (from 6.23 ± 2.52 to 3.75 ± 2.38) were observed postoperatively (p < 0.01). However, higher GS grades were associated with greater residual disability and pain at follow-up, as well as with smaller postoperative improvements in these scores (p < 0.01 for ODI; p = 0.01 for VAS). Gender differences were noted, with females predominating in higher GS grades. No significant differences in comorbidities or complication rates were identified across GS subgroups. Conclusions: Preoperative paravertebral muscle degeneration, as measured by the GS, emerged as a significant predictor of postoperative disability and pain in elderly LSS patients. Incorporating GS assessment into preoperative planning may refine surgical risk stratification and inform shared decision-making to optimize long-term functional recovery.
