Background and Objectives: Pyogenic spinal infections pose therapeutic challenges, with the optimal treatment approach remaining contentious. This study aimed to compare outcomes of conservative vs early surgical treatment (SuT) modalities in primary pyogenic spondylodiskitis through an international cohort analysis., Methods: A retrospective outcome analysis was conducted of 392 patients from the United Kingdom and Germany, treated between 2017 and 2022 with primary pyogenic spondylodiskitis. Patients were stratified by treatment modality. Propensity score matching, facilitated by a directed acyclic graph and principal component analysis, was used to balance risk factors between the compared patient cohorts. Primary outcome was mortality rate, while secondary outcomes included hospitalization duration, infection relapse, and neurological status at discharge., Results: The study included 95 patients undergoing conservative treatment, primarily treated in the United Kingdom, and 297 receiving SuT, predominantly in Germany. The mortality rate was notably higher in the conservative group (P < .001), while the surgical cohort experienced a shorter hospitalization duration (P < .01). After propensity score matching, 2 comparable cohorts of 95 patients each emerged. Subsequent analysis revealed a markedly increased mortality in the conservative group (24.2% for conservative treatment vs 4.2% for SuT, P < .001). Neither relapse nor neurological status at discharge showed significant differences between the groups., Conclusion: The study indicates that early surgical intervention may be more effective than conservative management in reducing mortality and hospital stay for patients with primary pyogenic spondylodiskitis. These findings highlight the need for prospective trials and more definitive treatment guidelines., (Copyright © 2024 The Author(s).

Purpose: Spontaneous spinal hematoma (SSH), a rare neurological disorder, demands immediate diagnostic evaluation and intervention to prevent lasting deficits. This case series analyzes instances, particularly highlighting cases where vascular causes were identified despite inconclusive initial imaging., Methods: In a retrospective study of 20 patients treated for SSH at a Level I spine center from 01/01/2017 to 11/15/2023, we examined demographics, clinical presentation, imaging, and treatment details. Excluding traumatic cases, we present 4 instances of SSH associated with diverse vascular pathologies., Results: Patient ages ranged from 39 to 85 years, with a median age of 66 years. 45% were male, and 55% were female. Among 20 cases, 14 were epidural hematomas, 4 subdural, 1 combined epidural and subdural, and 1 subarachnoid hemorrhage. 85% presented with neurological deficits, while 3 solely had pain-related symptoms. 55% were under anticoagulant medication, and vascular anomalies were found in 25% of cases. The cause of SSH remained unclear in 20% of cases. MRI was performed for all patients, and DSA was conducted in 25% of cases. The 4 highlighted cases involved individuals with distinct vascular pathologies managed surgically., Conclusion: Urgent attention is crucial for SSH due to possible lasting neurological consequences. The study emphasizes comprehensive diagnostics and surgical exploration, especially in cases with unclear etiology, to identify and address vascular causes, preventing hematoma progression or recurrence. Despite their rarity, vascular malformations contributing to spinal hematomas warrant particular attention., (© 2024. The Author(s).)

Background: Effective management of patients with aneurysmal subarachnoid hemorrhage (aSAH) demands vigilant monitoring and treatment, given the risks of complications such as cerebral vasospasm and delayed ischemic neurological deficits (DINDs). Transcranial transmission ultrasound (TTUS) is a well-established technique for assessing brain pulsatility. This pilot study aims to explore the utility of TTUS in detecting impaired intracerebral blood flow associated with DINDs., Observations: The authors examined 2 male patients, ages 45 and 52 years, with aSAH Hunt and Hess grades 4 and 2, respectively, who developed DINDs during their clinical course. Simultaneous recordings of arterial blood pressure, heart rate, and TTUS measurements were obtained in the intensive care unit. TTUS analysis revealed abnormal arrhythmic wave patterns during DIND episodes, whereas baseline measurements on DIND-free days showed no abnormalities. Following endovascular spasmolysis, TTUS demonstrated a normalization of abnormal waves, returning to baseline levels, alongside the resolution of neurological symptoms., Lessons: TTUS, a noninvasive method for assessing brain pulsatility, shows promise as a novel tool for monitoring aSAH patients, potentially aiding in prompt diagnostics and additional therapeutic interventions. Its capacity to provide further insights for individuals at risk of delayed cerebral ischemia warrants further investigation in clinical studies. https://thejns.org/doi/10.3171/CASE24146.

In recent years, there has been a growing interest in the role of the microbiome in cardiovascular and cerebrovascular diseases. Emerging research highlights the potential role of the microbiome in intracranial aneurysm (IA) formation and rupture, particularly in relation to inflammation. In this review, we aim to explore the existing literature regarding the influence of the gut and oral microbiome on IA formation and rupture. In the first section, we provide background information, elucidating the connection between inflammation and aneurysm formation and presenting potential mechanisms of gut-brain interaction. Additionally, we explain the methods for microbiome analysis. The second section reviews existing studies that investigate the relationship between the gut and oral microbiome and IAs. We conclude with a prospective overview, highlighting the extent to which the microbiome is already therapeutically utilized in other fields. Furthermore, we address the challenges associated with the context of IAs that still need to be overcome.

Purpose: The use of intraoperative MRI (ioMRI) contributes to an improved extent of resection. Hybrid operating room MRI suites have been established, with the patient being transferred to the MRI scanner. In the present descriptive analysis, we compared the rate of surgical site infections (SSI) after intracranial tumor surgery with and without the use of ioMRI., Methods: In this retrospective study, we included 446 patients with open craniotomy performed for brain tumor surgery. One hundred fourteen patients were operated on with the use of ioMRI between June 1, 2018, and June 30, 2019 (group 1). During the same period, 126 patients were operated on without ioMRI (group 2). As an additional control group, we analyzed 206 patients operated on from February 1, 2017, to February 28, 2018 when ioMRI had not yet been implemented (group 3)., Results: The rate of SSI in group 1 (11.4%), group 2 (9.5%), and group 3 (6.8%) did not differ significantly (p = 0.352). Additional resection after ioMRI did not result in a significantly elevated number of SSI. No significant influence of re-resection, prior radio-/chemotherapy, blood loss or duration of surgery was found on the incidence of SSI., Conclusion: Despite the transfer to a non-sterile MRI scanner, leading to a prolonged operation time, SSI rates with and without the use of ioMRI did not differ significantly. Hence, advantages of ioMRI outweigh potential disadvantages as confirmed by this real-life single-center study., (© 2023. The Author(s).)

(1) Background: There is a marked proportion of spondylodiscitis patients who die during the early stage of the disease despite the applied therapy. This study investigates this early mortality and explores the associated risk factors. (2) Methods: We conducted a retrospective analysis of spondylodiscitis patients treated at our Level I spine center between 1 January 2018 and 31 December 2022. (3) Results: Among 430 patients, 32 (7.4%) died during their hospital stay, with a median time of 28.5 days (range: 2.0-84.0 days). Six of these patients (18.75%) did not undergo surgery due to dire clinical conditions or death prior to scheduled surgery. Identified causes of in-hospital death included multiorgan failure ( n = 15), acute bone marrow failure (2), cardiac failure (4), liver failure (2), acute respiratory failure (2), acute renal failure (1), and concomitant oncological disease (1). In a simple logistic regression analysis, advanced age ( p = 0.0006), diabetes mellitus ( p = 0.0002), previous steroid medication ( p = 0.0279), Charlson Comorbidity Index ( p < 0.0001), and GFR level at admission ( p = 0.0008) were significant risk factors for in-hospital death. In a multiple logistic regression analysis, advanced age ( p = 0.0038), diabetes mellitus ( p = 0.0002), and previous steroid medication ( p = 0.0281) remained significant. (4) Conclusions: Despite immediate treatment, a subset of spondylodiscitis patients experience early mortality. Particular attention should be given to elderly patients and those with diabetes or a history of steroid medication, as they face an elevated risk of a rapidly progressing and fatal disease.

(1) Background: Surgery for spinal metastases has gained a decisive role in modern oncological treatment. Recently, carbon-fiber-reinforced (CFR) polyethyl-ether-ether-ketone (PEEK) pedicle screw systems were introduced, reducing artifacts on imaging and showing less perturbation effects on photon radiation. Preliminary clinical experience with CFR-PEEK implants for spinal metastases exists. The aim of this monocentric study is to report on the safety and efficacy of CFR-PEEK pedicle screw systems for spinal neoplasms in a large cohort of consecutive patients. (2) Methods: We retrospectively analyzed prospectively the collected data of consecutive patients being operated on from 1 August 2015 to 31 October 2021 using a CFR-PEEK pedicle screw system for posterior stabilization because of spinal metastases or primary bone tumors of the spine. (3) Results: We included 321 patients of a mean age of 65 ± 13 years. On average, 5 ± 2 levels were instrumented. Anterior reconstruction was performed in 121 (37.7%) patients. Intraoperative complications were documented in 30 (9.3%) patients. Revision surgery for postoperative complications was necessary in 55 (17.1%) patients. Implant-related complications, such as intraoperative screw breakage (3.4%) and screw loosening (2.2%), were rare. (4) Conclusions: CFR-PEEK is a safe and efficient alternative to titanium for oncological spinal instrumentation, with low complication and revision rates in routine use and with the advantage of its radiolucency.

Background: Patients with metastatic spinal cord compression (MSCC) may experience long-term functional impairment. It has been established that surgical decompression improves neurological outcomes, but the effect of early surgery remains uncertain. Our objective was to evaluate the impact of early versus late surgery for acute MSCC due to spinal metastases (SM). Methods: We retrospectively reviewed a consecutive cohort of all patients undergoing surgery for SMs at our institution. We determined the prevalence of acute MSCC; the time between acute neurological deterioration as well as between admission and surgery (standard procedure: decompression and instrumentation); and neurological impairment graded by the ASIA scale upon presentation and discharge. Results: We screened 693 patients with surgery for spinal metastasis; 140 patients (21.7%) had acute MSCC, defined as neurological impairment corresponding to ASIA grade D or lower, acquired within 72 h before admission. Non-MSCC patients had surgery for SM-related cauda equina syndrome, radiculopathy and/or spinal instability. Most common locations of the SM in acute MSCC were the thoracic (77.9%) and cervical (10.7%) spine. Per standard of care, acute MSCC patients underwent surgery including decompression and instrumentation, and the median time from admission to surgery was 16 h (interquartile range 10-22 h). Within the group of patients with acute MSCC, those who underwent early surgery (i.e., before the median 16 h) had a significantly higher rate of ASIA improvement by at least one grade at discharge (26.5%) compared to those who had late surgery after 16 h (10.1%; p = 0.024). Except for a significantly higher sepsis rate in the late surgery group, complication rates did not differ between the late and early surgery subgroups. Conclusions: We report data on the largest cohort of patients with MSCC to date. Early surgery is pivotal in acute MSCC, substantially increasing the chance for neurological improvement without increasing complication rates. We found no significant impact when surgery was performed later than 24 h after admission. These findings will provide the framework for a much-needed prospective study. Until then, the treatment strategy should entail the earliest possible surgical intervention.

Objective: To investigate the complication rates and long-term implant failure rates in a monocentric study of a consecutive cohort of patients with thoracolumbar spinal metastases after posterior instrumentation with a fenestrated carbon fiber-reinforced poly-ether-ether-ketone (CFRP) pedicle screw system., Methods: We retrospectively reviewed demographics, Karnofsky Performance Status Scale scores, complications, and implant failure rates., Results: Between June 2016 and November 2019, 51 consecutive patients underwent cement-augmented CFRP pedicle screw instrumentation at our institution. Mean age was 68 years (standard deviation 10.5), the median preoperative Karnofsky Performance Status Scale of 80 increased to 90 postoperatively (P = 0.471). Most common primary entities were breast (25.5%), lung (15.7%), and prostate (13.7%) cancers. Of 428 placed screws, 293 (68.5%) were augmented with polymethylmethacrylate, a mean 6 per patient (standard deviation ±2). Screws were inserted via a minimally invasive system technique in 54.9% of cases. In total, 11.8% of patients had immediate postoperative sequelae related to the cement. Pulmonary cement embolisms were noted in 3 patients, 2 had paravertebral extravasation, and 1 had an embolism into a segmental artery. Of these 6, 2 patients with pulmonary embolisms reported related symptoms. Follow-up was available for 80.4%. After a mean 9.8 months, screw loosening was noted in 11.8% of cases on computed tomography, although it was asymptomatic in all but 1 patient. Screw pull-out did not occur. Neither cement-related (P = 0.353) nor general complication rates (P = 0.507) differed significantly between open and minimally invasive system techniques., Conclusions: Percutaneous cement-augmented CFRP pedicle screw instrumentation facilitates artifact-reduced postoperative imaging, while maintaining a risk profile and implant failure rates comparable to conventional metallic instrumentation., (Copyright © 2021 Elsevier Inc.

Background:  Intraoperative neurophysiologic monitoring (IONM) has increased patient safety and extent of resection in patients with eloquent brain tumors. Despite its comprehensive capability for the resection of intramedullary spinal cord tumors (ISCTs), the application during the resection of these tumors is controversial., Methods:  We retrospectively analyzed the resection of ISCTs in 83 consecutive cases. IONM was performed in all cases. Each patient's motor status and the McCormick scale was determined preoperatively, directly after surgery, at the day of discharge, and at long-term follow-up., Results:  IONM was feasible in 71 cases (85.5%). Gross total resection was performed in 75 cases (90.4%). Postoperatively, patients showed new transient deficits in 12 cases (14.5%) and new permanent deficits in 12 cases (14.5%). The mean McCormick variance between baseline and long-term follow-up was - 0.08 ± 0.54. IONM's sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the patient's motor status at the day of discharge was 75.0%, 64.7%, 45.5%, and 86.8%. It was 88.9%, 59.7%, 24.2%, and 97.4% for the motor outcome at long-term follow-up. Patients experienced postoperative complications in 15 cases (18.1%)., Conclusion:  IONM, as performed in the present study, shows a high sensitivity and NPV but low specificity and PPV, particularly for the patient's motor status at the long-term follow-up. As far as practicable by a retrospective study on IONM, our results confirm IONM's usefulness for its application during the resection of ISCTs. However, these results must be approved by a prospective study., Competing Interests: None declared., (Thieme. All rights reserved.)

The management of patients with spinal metastases (SM) requires a multidisciplinary team of specialists involved in oncological care. Surgical management has evolved significantly over the recent years, which warrants reevaluation of its role in the oncological treatment concept. Any patient with a SM was screened for study inclusion. We report baseline characteristics, surgical procedures, complication rates, functional status and outcome of a large consecutive cohort undergoing surgical treatment according to an algorithm. 667 patients underwent 989 surgeries with a mean age of 65 years (min/max 20-94) between 2007 and 2018. The primary cancers mostly originated from the prostate (21.7%), breast (15.9%) and lung (10.0%). Surgical treatment consisted of dorsoventral stabilization in 69.5%, decompression without instrumentation in 12.5% and kyphoplasty in 18.0%. Overall survival reached 18.4 months (95% CI 9.8-26.9) and the median KPS increased by 10 within hospital stay. Surgical management of SMs should generally represent the first step of a conclusive treatment algorithm. The need to preserve long-term symptom control and biomechanical stability requires a surgical strategy currently not supported by level I evidence.

Radiolucent carbon-fiber-reinforced (CFR) polyethyl-ether-ether-ketone (PEEK) has been established in spinal instrumentation for oncological reasons. Laboratory data reported comparable bacterial adhesion as titanium. Thus, using of CFR-PEEK spinal instrumentation for spondylodiscitis bases on artifact-free imaging to evaluate therapeutic success. Studies comparing the rate of pedicle screw loosening and relapse of spondylodiscitis following titanium versus CFR-PEEK instrumentation do not exist so far. This study evaluates the rate of pedicle screw loosening and recurrence of spondylodiscitis after CFR-PEEK instrumentation for spondylodiscitis compared to titanium. We conducted a prospective single center study between June 2018 and March 2019 on consecutive 23 patients with thoracolumbar spondylodiscitis. Imaging data was evaluated for screw loosening at a minimum of three months after surgery. A matched-pair analysis was performed using spondylodiscitis cases between 2014 and 2016 using titanium instrumentation for equal localization, surgery, and microorganism class. Among 17 cases with follow-up imaging, six cases (35%) showed screw loosening while only 14% (two patients) with titanium instrumentation were loosened (p = 0.004). In both groups the most frequent bacterium was Staphylococcus aureus, followed by Staphylococcus epidermidis. From the S. aureus cases, one infection in both groups was caused by methicillin resistant species (MRSA). No difference was found in the rate of 360° fusion in either group due to matching criteria. As opposed to other indications CFR-PEEK screws show more loosening than titanium in this series with two potentially underlying reasons: a probably stronger bacterial adhesion on CFR-PEEK in vivo as shown by a statistical trend in vitro and instrumentation of spondylytic vertebrae. Until these factors are validated, we advise caution when implanting CFR-PEEK screws in infectious cases.

Background: Spinal instrumentation can be associated with complications, including implant loosening. Hitherto, implant loosening has mainly been attributed to mechanical overload., Objective: To examine the role of low-grade infections as the cause of implant failure in suspected aseptic implant loosening following spinal instrumentation., Methods: A prospective single center observational study was performed. All patients who had revision surgery following spinal instrumentation between August 2015 and February 2018 were screened. Patients with revision surgery due to screw loosening on the computed tomograhy scan constituted the study group. Patients in which the screws where not loosened but removal was performed for other reasons formed the comparison group. Intraoperative swabs were taken and sonication was performed with the explanted material. Results of microbiological cultivation were analyzed., Results: A total of 59 patients were included in the study group and 34 in the comparison group. In the study group in 42.4% of the cultures a bacterium was detected, while in the comparison group only in 17.6%. 84%, and 83.3% of these germs were detected by sonication in the study and comparison group, respectively. The rate of positive cultures was significantly higher in the study group compared to the comparison group (P = .001). The most frequent bacterium cultivated in both groups was Propionibacterium acnes, followed by Staphylococcus species., Conclusion: For patients with screw loosening a high level of suspicion for a low-grade infection should be raised. Cultures should be performed from the sonication fluid of the explanted devices in all patients with symptomatic screw loosening., (Copyright © 2020 by the Congress of Neurological Surgeons.)

We aimed to identify independent psychological predictors of quality of life (QOL) and functional outcome after anterior cervical discectomy and fusion (ACDF) for degenerative cervical spine disease. We prospectively included patients undergoing ACDF for degenerative cervical disc herniation and stenosis. Patients completed a structured psychological assessment including the Center for Epidemiological Studies Depression Scale (ADS-K), Post-Traumatic Stress Scale-10 (PTSS-10), State Trait Anxiety Inventory-State Anxiety and - Trait Anxiety (STAI-S and STAI-T) and Anxiety Sensitivity Index-3 (ASI-3) before surgery, after 3 and 12 months. Outcome measures included EuroQol-5D (EQ), Short Form-36 (SF-36) and Oswestry Disability Index (ODI) scores. Of 104 included patients who underwent ACDF between March 2013 and November 2017, 92 completed follow-up after 3 and 12 months. The mean Visual Analogue Scale (VAS) scores for neck pain (- 1.4; p < .001) and arm pain (- 1.8; p = .031) significantly decreased by 12 months. QOL scores significantly increased by 3 months (EQ: + 0.2; p < .001; SF-36 PCS: + 6.2; p < .001; SF-36 MCS: + 2.5; p = .044), a benefit which was retained at 12 months. Linear regression analyses identified statistically significant predictors in preoperative ASI-3, SF-36 MCS and STAI-S for postoperative QOL and ODI scores. There is a benefit for patients in terms of quality of life and function after undergoing surgery for degenerative cervical spine disease. With the ASI-3, SF-36 MCS and STAI-S there exist some predictors for postoperative QOL and ODI scores.

Objective: To quantify the correlation between patients' psychopathological predisposition, disability and health-related quality of life (QOL) after surgery for degenerative lumbar spine disease., Methods: We prospectively included patients undergoing decompression for degenerative lumbar spinal stenosis, spondylolisthesis or disc herniation with additional fusion of up to two segments. Patients completed a structured psychological assessment including the Center for Epidemiological Studies Depression Scale (ADS-K), Post-Traumatic Stress Scale-10 (PTSS-10), State Trait Anxiety Inventory-State Anxiety and State Trait Anxiety Inventory-Trait Anxiety (STAI-S and STAI-T) and Anxiety Sensitivity Index-3 (ASI-3) before surgery, after 3 and 12 months. Outcome measures included EuroQol 5D (EQ), Short Form-36 (SF-36) and Oswestry Disability Index (ODI) scores., Results: In total, 245 patients between March 2013 and November 2017 received surgery, of which 180 (73.5%) fully completed follow-up after 3 months and 12 months. QOL scores significantly increased by 3 months (EQ: +0.2; p < 0.001; SF-36 PCS: +7.0; p < 0.001; SF-36 MCS: +3.3; p = 0.018), a benefit which was retained at 12 months, without statistically significant difference between fused and non-fused patients. Depressed patients exhibited impaired mean scores of EQ (0.58 vs. 0.36; p < 0.001) and ODI mean scores (35.5 vs. 51.9; p < 0.001) at baseline, which significantly improved and converged with scores of non-depressed patients after 12 months. Linear regression analysis identified statistically significant predictors in age, STAI-T and SF-36 MCS for post-operative QOL and disability., Conclusion: Despite exhibiting pronounced psychological distress preoperatively, patients may significantly benefit from surgery with an outcome equal to psychologically healthy patients after 12 months.

Background: Some recent studies indicate correlations between cervical alignment and clinical outcome after anterior cervical discectomy and fusion (ACDF) surgery. However, there still are no established criteria for the interpretation of alignment, fusion and subsidence in relation to clinical outcome., Methods: A retrospective analysis of 208 radiographs of patients following ACDF with stand-alone PEEK cage implantation was performed. The measurements were obtained on plain radiographs in lateral and anteroposterior projections as well as flexion/extension radiographs. Cervical alignment was measured using the Gore, Laing and Cobb methods; fusion was evaluated by an assortment of radiographic hallmarks: the presence of bridging bone, the Cobb angle and the distances between the tips and bases of the spinous processes of the operated segments, respectively. For assessment of subsidence, we used the Mochida method in addition to ventral and dorsal segmental height reduction. Correlation analysis between the different radiological characteristics and clinical outcome at a minimum follow-up of 12 months was conducted., Results: Two hundred and eight patients were evaluated for alignment, fusion and subsidence. Cervical alignment using the Gore and Cobb methods correlated among each other, but failed to exhibit significant correlation with clinical outcome. Interpretation of fusion rates varied greatly (43.9 to 89.4%) depending on the criteria used. Pearson coefficients between radiographic presence of pseudarthrosis and the measurements of the spinous process distances (0.595; p < 0.001), the Cobb angles (0.187; p = 0.007) and the presence of bridging bone (0.224; p < 0.001) each exhibited statistical significance. None of the methods employed significantly correlated with clinical outcome. Regarding subsidence, we found rates of 62%, 48% and 27% using the Mochida, ventral and dorsal segmental height reduction assessment methods, respectively. Pearson correlations between pairs of Mochida/ventral (r = 0.39; p = 0.66) and Mochida/dorsal (r = 0.007; p = 0.921) height reduction assessment methods were weak and no significant correlation between subsidence rates and clinical outcome was shown., Conclusion: All measured parameters varied depending in the measurement method used. This was most pronounced for fusion. There was a moderate positive correlation between neck pain and subsidence as measured by the Mochida method.

Objective: To analyze psychopathological outcome and health-related quality of life (QOL) for cohorts of patients undergoing transcranial or transnasal anterior skull base surgery., Methods: A prospective study of patients undergoing elective surgery for various entities of the anterior skull base was performed. Evaluation for depression (ADS-K score) and anxiety (PTSS, STAI-S, STAI-T, and ASI-3 scores) was done before surgery, at 3 and 12 months after surgery. The correlation between preoperative psychological burden and postoperative quality of life as measured by the SF-36 and EuroQol questionnaires was analyzed. Incidence and influence of these psychiatric comorbidities on clinical outcome were examined and compared between transnasal and transcranial subgroups., Results: We included 54 patients scheduled for surgery of a pituitary adenoma or meningioma of the anterior skull base between January 2013 and July 2017. Of these, a cohort of 40 (74.1%) completed follow-up interviews after 3 and 12 months. There were 60.0% female patients, median age was 57 years. 57.5% of patients had a meningioma and were operated transcranially, while 42.5% of patients received transnasal surgery for pituitary adenoma. The proportion of pathological anxiety scores significantly decreased from 75.0 to 45.0% (p = 0.002), without difference between transnasal and transcranial subgroups. After 3 months, mean EuroQol VAS score non-significantly increased by 0.07 (p = 0.236) across the entire cohort without significant difference between transcranial and transnasal subgroups (p = 0.478). The transnasal cohort tended to score higher in anxiety scores, whereas the transcranial cohort demonstrated higher depression scores without significant difference, respectively. The individually declared emotional burden significantly decreased from 6.7 to 4.0 on the ten-point Likert scale (p < 0.001) equally for both subgroups (transnasal, - 2.3; transcranial, - 3.0; p = 0.174). On last examination, about half of the patients in each subgroup (41.2% vs. 52.2%; p = 0.491) expressed a considerable recovery of preoperative bodily complaints such as headaches, dizziness, and unrest defined as a score of at least 8 on the Likert scaled item., Conclusion: Both transnasal and transcranial approaches yield favorable postoperative QOL and psychopathological outcomes. The postoperative increase in QOL is partly influenced by preoperative expression of mental distress, which tends to resolve postoperatively.

Tentorial meningiomas (TMs) may challenge the surgeon with their close association to neurovascular structures. We analyzed a consecutive series with regard to surgical and functional outcome following microsurgical resection. We retrospectively reviewed patient charts and imaging data of every patient with a TM resected at a single institution and compared surgical and functional outcomes between groups stratified by choice of approach. 57 consecutive patients from October 2006 to September 2017 were included, of which 75.4% were female; mean age was 60 years (range 31-90), follow-up data was available for 85.4% and reached a mean of 18.3 (range 2-119) months with a median of 14.5 months. 54.4% of TMs were located at the medial compartments of the tentorium, 45.6% at the lateral edges. Complete resection defined as Simpson grades I and II was achieved in 72% of all cases, without statistically significant differences for both subgroups (p = 0.532). 9 patients (15.8%) developed a new cranial nerve palsy postoperatively with the vestibulocochlear nerve affected exclusively in the lateral subgroup (8.8% of total), followed by disturbances of oculomotion (5.4%). After 12 months, 93.0% of patients with available follow-up after 12 months retained fully independent functional status without deficit. Despite providing a surgical challenge due to potentially complicated anatomical relations, the choice of an appropriate surgical strategy overall results in favourable oncological and functional outcome after resection of TMs.

Objective: Meningiomas are the most common intracranial neoplasm. Evidence concerning surgical management and outcome is abundant, while the implications for the quality of life (QOL) of a patient confronted with the diagnosis and undergoing surgery are unclear. The authors conducted a prospective study to evaluate QOL in relation to psychological comorbidities comorbidities., Methods: A prospective study of patients undergoing elective surgery for the removal of an intracranial meningioma was performed. The authors evaluated depression (Allgemeine Depressionsskala K score) and anxiety (Post-Traumatic Stress Scale-10 [PTSS-10]; State Trait Anxiety Inventory-State Anxiety and -Trait Anxiety [STAI-S and STAI-T]; and Anxiety Sensitivity Index-3 [ASI-3]) scores before surgery and at 3 and 12 months after surgery. The correlation between preoperative psychological burden and postoperative QOL as measured by the 36-Item Short Form Health Survey and EQ-5L questionnaires was analyzed. Incidence and influence of these psychiatric comorbidities on clinical outcome were examined., Results: A total of 78 patients undergoing resection of a meningioma between January 2013 and September 2017 participated in the preoperative psychological screening and 71 patients fully completed postoperative follow-up examination after 1 year of follow-up. At presentation, 48 patients (67.7%) had abnormal anxiety scores, which decreased to 29.6% (p = 0.003). On follow-up at 12 months, mean EQ-5L visual analog scale scores were significantly lower in patients with pathological scores on the PTSS-10 (0.84 vs 0.69; p = 0.004), STAI-S (0.86 vs 0.68; p = 0.001), and STAI-T (0.85 vs 0.71; p = 0.011). Neurological status (modified Rankin Scale) improved slightly and showed some correlation with psychological comorbidities QOL scores (p = 0.167). There was a nonsignificant increase of EQ-5L scores over the period of follow-up (p = 0.174) in the repeated-measures analysis. In the regression analysis, impaired QOL and physical disability on follow-up correlated with elevated preoperative anxiety and depression levels., Conclusions: The QOL and physical disability of patients undergoing resection of an intracranial meningioma highly depend on preoperative anxiety and depression levels. Stress and anxiety scores generally decrease after the resection, which leads us to conclude that there is a tremendous emotional burden caused by an upcoming surgery, necessitating close psychooncological support in order to uphold functional outcome and health-related QOL in the postoperative course.
