- Abstract
Objective: The expanded endonasal transpterygoid approach (EETA) is used to access the middle and posterior fossa through the pterygoid process. Traditionally, the eustachian tube (ET) was resected during EETA, which often required subsequent myringotomy for inner ear drainage. Anterolateral transposition of the ET was proposed to decrease potential morbidity associated with resection. However, a comparison of resection versus transposition regarding the need for subsequent myringotomy has not been reported. Methods: This is a retrospective cohort study of patients who underwent an EETA. Patient demographics, tumor characteristics, management of ET with resection versus transposition, and need for subsequent myringotomy were collected. Analysis was performed with JMP software in standard fashion and univariate and multivariate logistic regression analysis performed with a p < 0.05 was considered significant. Results: Ninety‐one patients underwent EETA for various malignant and benign tumors. Twenty‐seven patients required myringotomy, with tumors of the pterygopalatine fossa accounting for the most common location (n = 8). Malignant pathology had the highest myringotomy rate compared to benign tumors (48.9% vs. 10.9%, p < 0.001), as did receiving postoperative radiation (p < 0.001), ET resection (p < 0.001), and increasing CPK class. Multivariate analysis of these variables suggests that only ET resection significantly correlated with the need for myringotomy (LR 7.97, p = 0.005). Conclusions: ET resection during EETA can lead to ET dysfunction and require myringotomy post‐operatively, and patients should be counseled of this risk. Radiation treatment, malignant pathology, and CPK class, all reflecting situations where more extensive surgery was needed, were associated with the need for myringotomy on univariate analysis but did not reach significance with multivariate analysis.

MYRINGOTOMY , *INNER ear - Abstract
This article discusses the use of the expanded endonasal transpterygoid approach (EETA) in accessing the middle and posterior fossa through the pterygoid process. Traditionally, the eustachian tube (ET) was resected during EETA, which often required subsequent myringotomy for inner ear drainage. However, anterolateral transposition of the ET has been proposed as an alternative to decrease potential morbidity. This retrospective cohort study found that ET resection during EETA was significantly correlated with the need for myringotomy post-operatively. Patients should be counseled about this risk, while other factors such as radiation treatment, malignant pathology, and CPK class were associated with the need for myringotomy but did not reach significance in multivariate analysis.

PITUITARY gland ,CONFLICT of interests - Abstract
The article titled "Intradural Pituitary Hemitransposition: Technical Note and Case Series Illustration" discusses the challenges of accessing lesions in the retrosellar, interpeduncular cistern, and petroclival regions in neurosurgery. The authors propose the endonasal endoscopic intradural pituitary hemitransposition approach as an effective technique for resecting these lesions while preserving pituitary function. The approach involves mobilizing the pituitary gland to safely access the interpeduncular fossa through a midline transsphenoidal route. The article is authored by Joao Paulo Almeida, Guilherme Finger, Matthieu D. Weber, Mark A. Damante, Kyle C. Wu, Patrick Walz, Jeffrey R. Leonard, Ricardo L. Carrau, and Daniel M. Prevedello.

Simple Summary: Low-grade gliomas are slow-growing, progressive tumors of the brain that invariably become high grade. They present a challenging entity because they can invade normal brain without many changes on radiologic scans. Standard treatment involves maximal safe removal via surgery, then close monitoring or other treatments, depending on whether portions were left. Some authors recommend removing a larger area of the brain than can be seen as tumor on imaging (called supratotal resection) because it theoretically gives patients a potential for longer disease-free survival. However, removing the adjacent "normal" brain carries the risk of neurological harm, which has tempered widespread adoption of the supratotal technique in lieu of preserving patients' function. In this review, literature surrounding supratotal resection is explored systematically, and while there are no randomized trials, some evidence may suggest that supratotal resection is safe and effective as standard resection. Further studies are required to fully answer this question. Low-grade gliomas (LGGs) are optimally treated with up-front maximal safe surgical resection, typically defined as maximizing the extent of tumor resection while minimizing neurologic risks of surgery. Supratotal resection of LGG may improve outcomes beyond gross total resection by removing tumor cells invading beyond the tumor border as defined on MRI. However, the evidence regarding supratotal resection of LGG, in terms of impact on clinical outcomes, such as overall survival and neurologic morbidities, remains unclear. Authors independently searched the PubMed, Medline, Ovid, CENTRAL (Cochrane Central Register of Controlled Trials), and Google Scholar databases for studies evaluating overall survival, time to progression, seizure outcomes, and postoperative neurologic and medical complications of supratotal resection/FLAIRectomy of WHO-defined LGGs. Papers in languages other than English, lacking full-text availability, evaluating supratotal resection of WHO-defined high-grade gliomas only, and nonhuman studies were excluded. After literature search, reference screening, and initial exclusions, 65 studies were screened for relevancy, of which 23 were evaluated via full-text review, and 10 were ultimately included in the final evidence review. Studies were evaluated for quality using the MINORS criteria. After data extraction, a total of 1301 LGG patients were included in the analysis, with 377 (29.0%) undergoing supratotal resection. The main measured outcomes were extent of resection, pre- and postoperative neurological deficits, seizure control, adjuvant treatment, neuropsychological outcomes, ability to return to work, progression-free survival, and overall survival. Overall, low- to moderate-quality evidence was supportive of aggressive, functional boundary-based resection of LGGs due to improvements in progression-free survival and seizure control. The published literature provides a moderate amount of low-quality evidence supporting supratotal surgical resection along functional boundaries for low-grade glioma. Among patients included in this analysis, the occurrence of postoperative neurological deficits was low, and nearly all patients recovered within 3 to 6 months after surgery. Notably, the surgical centers represented in this analysis have significant experience in glioma surgery in general, and supratotal resection specifically. In this setting, supratotal surgical resection along functional boundaries appears to be appropriate for both symptomatic and asymptomatic low-grade glioma patients. Larger clinical studies are needed to better define the role of supratotal resection in LGG. [ABSTRACT FROM AUTHOR]

Central venous occlusive disease secondary to chronic hemodialysis catheterization rarely progresses to encephalopathy, cerebral infarction, and/or hemorrhage. A 59-year-old male with 15 years of haemodialysis-dependent end-stage renal disease presented with acutely altered mental status, extensor rigidity with left hemiparesis and equal, but small and nonreactive pupils. Magnetic resonance imaging demonstrated infarction and cerebral edema. Cranial angiogram through right brachial artery injection revealed right subclavian vein opacification via a patent AV-fistula and retrograde flow to the right internal jugular vein and superior sagittal sinus secondary to occlusion of the brachiocephalic vein. All cerebral and right upper extremity venous drainage occurred via the contralateral venous outflow tract. Internal carotid artery injections revealed significant venous congestion. Despite successful angioplasty with stenting and resolution of venous flow reversal, the patient failed to recover neurologically. The devastating nature of the presented case emphasizes the need for frequent neurologic evaluation of such patients to avoid catastrophic cerebrovascular injury. [ABSTRACT FROM AUTHOR]

Background: Alveolar soft part sarcoma (ASPS) is a rare soft-tissue sarcoma with a propensity for early hematogenous dissemination to the lungs and frequent brain metastasis. The development of lung metastasis almost invariably precedes intracranial involvement. There are no previously reported cases in which a patient was synchronously diagnosed with ASPS and multiple brain metastasis without lung involvement. Case Description: A 29-year-old gentleman was found to have three intracranial lesions following the onset of generalized seizures. Staging studies identified a soft-tissue mass in the left thigh and an adjacent femoral lesion. Biopsy of the soft-tissue mass was consistent with ASPS. The patient then underwent neoadjuvant stereotactic radiotherapy to all three brain lesions, followed by en bloc resection of the dominant lesion. The patient was then started on a programmed death-ligand 1 (PD-L1) inhibitor. Subsequent surgical resection of the primary lesion and femur metastasis demonstrates a histopathologic complete response of the bony metastasis and partial response of the primary lesion. At present, the patient has received 14 cycles of atezolizumab without recurrence of the primary or bony lesions and the irradiated intracranial disease has remained stable without recurrence of the resected dominant lesion. Conclusion: While intracranial involvement is relatively common in ASPS, a case with multiple, synchronously diagnosed brain metastasis without concurrent lung metastasis has not been described. The presented case discusses the safety and efficacy of aggressive management of intracranial disease in the setting of atezolizumab. Prospective evaluation of the efficacy of checkpoint inhibitors and the prognostic value of PD-L1 expression in ASPS with brain metastasis are necessary. [ABSTRACT FROM AUTHOR]

Patient survival with renal cell carcinoma (RCC) has improved with the use of molecular targeted agents and immunotherapy. Given the potential activity of these agents in treating brain metastases, the role of aggressive local management with surgery and/or radiation may diminish. The aim of this study was to evaluate the role of aggressive local therapy for RCC brain metastasis in the setting of molecular targeted agents and/or checkpoint inhibitor therapy. A retrospective single-center review between 2011-2018 identified patients that developed brain metastasis from RCC. Data analyzed included demographic information, systemic treatments, intracranial interventions, progression free survival and overall survival (OS). Of 1194 patients, 108(9.0%) were diagnosed with brain metastasis from RCC. OS from diagnosis of brain metastasis (OS BM) was 12.3 months. OS BM was analyzed based on three treatment groups: systemic therapy (ST) only (2.0 months, n = 23), systemic and radiotherapy (RT + ST) (12.3 months, n = 52), and systemic and radiotherapy plus resection (Surg + RT + ST) (21.7 months, n = 33). Survival benefit was seen with Surg + RT + ST compared to ST (P = 0.001), but not RT + ST (P = 0.081). Progression free survival was significantly prolonged with Surg + RT + ST compared to RT + ST (10.9 vs 5.9 months, respectively, P = 0.04). Variables such as performance status and number of brain metastases at the time of brain metastasis diagnosis did not differ significantly. In the setting of molecular targeted agents and immunotherapy, resection may benefit the appropriate surgical candidate. Prospective clinical trials are necessary to better understand the role of aggressive RCC brain metastasis treatment. Micro Abstract • Renal cell brain metastasis is often excluded from studies and brain metastases effect a large portion of RCC patients. • Retrospective study of 1194 RCC patients, 108 patients had brain metastasis, determination of the role of surgical resection in the setting of recent advances in checkpoint inhibitors. • A benefit was seen in overall survival in patients that had surgical while undergoing radiation therapy and systemic therapies. • In the setting of molecular targeted agents and immunotherapy, resection may benefit the appropriate surgical candidate(s).

- Abstract
Background and Objectives: Lesions located in the retrosellar region, interpeduncular cistern, and petroclival region are among the most difficult to access in neurosurgery. Transcranial approaches are useful; however, the large distance between the surgeon and the lesion as well as the presence of major neurovascular structures surrounding the lesion may limit surgical exposure. A midline transsphenoidal route avoids transgression of the neurovascular plane and provides direct access to the interpeduncular cistern. To safely access the interpeduncular fossa, it requires mobilization of the pituitary gland. The pituitary hemitransposition technique permits mobilization of the gland, while preserving its venous drainage and arterial supply to the gland on one of its sides, preserving gland function. The authors aim to describe the intradural pituitary hemitransposition technique and to demonstrate its safe application for resection of skull base tumors in the retrosellar space., Methods: The authors describe the surgical technique and illustrate its application in 5 cases of different types of skull base tumors, including a video demonstrating all the steps to perform this approach. In addition, the authors discuss the advantages and limitations of this technique compared with other approaches to the retrosellar space., Results: The intradural pituitary hemitransposition technique was used to safely resect a chondrosarcoma, chordoma, craniopharyngioma, teratoma, and meningioma involving the parasellar and retrosellar spaces, while minimizing endocrine morbidity. We had one patient with mild, albeit permanent hyperprolactinemia and hypothyroidism after surgery. No other patients had permanent dysfunction related to surgery., Conclusion: The endonasal endoscopic intradural pituitary hemitransposition approach is an effective technique for resection of lesions located within the retrosellar and petroclival regions, allowing adequate exposure while potentially optimizing the preservation of the pituitary function., (Copyright © Congress of Neurological Surgeons 2023.

- Abstract
Background and Objectives: Cranial robotics are a burgeoning field of neurosurgery. To date, all cranial robotic systems described have been computerized, arm-based instruments that take up significant space in the operating room. The Medtronic Stealth Autoguide robot has a smaller operating room footprint and offers multiaxial, frame-based surgical targeting. The authors set out to define the surgical characteristics of a novel robotic platform for brain biopsy in a large patient cohort., Methods: Patients who underwent stereotactic biopsy using the Stealth Autoguide cranial robotic platform from July 2020 to March 2023 were included in this study. Clinical, surgical, and histological data were collected and analyzed., Results: Ninety-six consecutive patients (50 female, 46 male) were included. The mean age at biopsy was 53.7 ± 18.0 years. The mean target depth was 68.2 ± 15.3 mm. The biopsy diagnostic tissue acquisition rate was 100%. The mean time from incision to biopsy tissue acquisition was 15.4 ± 9.9 minutes. Target lesions were located throughout the brain: in the frontal lobe (n = 32, 33.3%), parietal lobe (n = 21, 21.9%), temporal lobe (n = 22, 22.9%), deep brain nuclei/thalamus (n = 13, 13.5%), cerebellum (n = 7, 7.3%), and brainstem (n = 1, 1.0%). Most cases were gliomas (n = 75, 78.2%). Patients were discharged home on postoperative day 0 or 1 in 62.5% of cases. A total of 7 patients developed postoperative complications (7.2%)., Conclusion: This cranial robotic platform can be used for efficient, safe, and accurate cranial biopsies that allow for reliable diagnosis of intracranial pathology in a minimally invasive setting., (Copyright © Congress of Neurological Surgeons 2023.

- Abstract
Objective: Management of olfactory groove meningiomas (OGMs) has changed significantly with the advances in extended endoscopic endonasal approaches (EEAs), which is an excellent approach for patients with anosmia since it allows early devascularization and minimizes retraction on the frontal lobes. Craniotomy is best suited for preservation of olfaction. However, not infrequently, a tumor presents after extending outside the reach of an EEA and a solely transcranial approach would require manipulation and retraction of the frontal lobes. These OGMs may best be treated by a staged EEA-craniotomy approach. In this study the authors' goal was to present their case series of patients with OGMs treated with their surgical approach algorithm., Methods: The authors conducted an IRB-approved, nonrandomized historic cohort including all consecutive cases of OGMs treated surgically between 2010 and 2020. Patient demographic information, presenting symptoms, operative details, and complications data were collected. Preoperative and postoperative tumor and T2/FLAIR intensity volumes were calculated using Visage Imaging software., Results: Thirty-one patients with OGMs were treated (14 craniotomy only, 11 EEA only, and 6 staged). There was a significant difference in the distribution of patients presenting with anosmia and visual disturbance by approach. Tumor size was significantly correlated with preoperative vasogenic edema. Gross-total resection was achieved in 90% of cases, with near-total resection occurring twice with EEA and once with a staged approach. T2/FLAIR hyperintensity completely resolved in 90% of cases and rates did not differ by approach. Complication rates were not significantly different by approach and included 4 CSF leaks (p = 0.68)., Conclusions: A staged approach for the management of large OGMs with associated anosmia and significant lateral extension is a safe and effective option for surgical management. Through utilization of the described algorithm, the authors achieved a high rate of GTR, and this strategy may be considered for large OGMs.

- Abstract
Background: The standard treatment for patients with large brain metastases and limited intracranial disease is surgical resection and post-operative stereotactic radiosurgery (SRS). However, post-operative SRS still has elevated rates of local failure (LF) and is complicated by radiation necrosis (RN), and meningeal disease (MD). Pre-operative SRS may reduce the risk of RN and MD, while fractionated therapy may improve local control through delivering a higher biological effective dose. We hypothesize that pre-operative fractionated stereotactic radiation therapy (FSRT) will have less toxicity compared to patients who receive post-operative SRS or FSRT., Methods: A multi-institutional analysis was conducted and included patients who had surgical resection and stereotactic radiation therapy to treat at least one brain metastasis. Pertinent demographic, clinical, radiation, surgical, and follow up data were collected for each patient. The primary outcome was a composite endpoint defined as patients with one of the following adverse events: 1) LF, 2) MD, and/or 3) Grade 2 or higher (symptomatic) RN., Results: 279 patients were eligible for analysis. The median follow-up time was 9 months. 87 % of patients received fractionated treatment. 29 % of patients received pre-operative treatment. The composite endpoint incidences for post-operative SRS (n = 10), post-operative FSRT (n = 189), pre-operative SRS (n = 27), and pre-operative FSRT (n = 53) were 0 %, 17 %, 15 %, and 7.5 %, respectively., Conclusions: In our study, the composite endpoint of 7.5% for pre-operative FSRT compares favorably to our post-operative FSRT rate of 17%. Pre-operative FSRT was observed to have low rates of LF, MD, and RN. Prospective validation is needed., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Author(s).)

25. Surgical Management of Recurrent Brain Metastasis: A Systematic Review of Laser Interstitial Thermal Therapy.

Damante MA Jr, Wang JL, and Elder JB
- Abstract
The incidence of recurrent metastatic brain tumors is increasing due to advances in local therapy, including surgical and radiosurgical management, as well as improved systemic disease control. The management of recurrent brain metastases was previously limited to open resection and/or irradiation. In recent years, laser interstitial thermal therapy (LITT) has become a promising treatment modality. As systemic and intracranial disease burden increases in a patient, patients may no longer be candidates for surgical resection. LITT offers a relatively minimally invasive option for patients that cannot tolerate or do not want open surgery, as well as an option for accessing deep-seated tumors that may be difficult to access via craniotomy. This manuscript aims to critically review the available data regarding the use of LITT for recurrent intracranial brain metastasis. Ten of seventy-two studies met the criteria for review. Generally, the available literature suggests that LITT is a safe and feasible option for the treatment of recurrent brain metastases involving supratentorial and cortical brain, as well as posterior fossa and deep-seated locations. Among all studies, only one directly compared craniotomy to LITT in the setting of recurrent brain metastasis. Prospective studies are needed to better elucidate the role of LITT in the management of recurrent brain metastases.
