Abstract BACKGROUND: Microsurgical resection via open approaches is considered the main treatment modality for cranial base chondrosarcomas (CBCs). The use of endoscopic endonasal approaches (EEAs) has been rarely reported. OBJECTIVE: To present the endoscopic endonasal experience with CBCs at our institution. METHODS: Retrospective review of the medical records of 35 consecutive patients who underwent EEA for CBC resection between January 2004 and April 2013. Surgical outcomes and variables that might affect extent of resection, complications, and recurrence were analyzed. RESULTS: Forty-eight operations were performed (42 EEAs and 6 open approaches). Gross-total resection was achieved in 22 patients (62.9%), near total (≥90% tumor resection) in 11 (31.4%). Larger tumors were associated with incomplete resection in univariate and multivariate analysis (P = .004, .015, respectively). In univariate analysis, tumors involving the lower clivus and cerebellopontine angle were associated with increased number of complications, especially postoperative cerebrospinal fluid leak (P = .015) and new cranial neuropathy (P = .037), respectively. Other major complications included 2 cases of meningitis and deep venous thrombosis, and 1 case of hydrocephalus and carotid injury. Involvement of the lower clivus, parapharyngeal space, and cervical spine required a combination of approaches to maximize tumor resection (P = .017, .044, .017, respectively). No predictors were significantly associated with increased risk of recurrence. The average follow-up time was 44.6 ± 31 months. CONCLUSIONS: EEAs may be considered a good option for managing CBCs without significant posterolateral extension beyond the basal foramina and can be used in conjunction with open approaches for maximal resection with acceptable morbidity.

ABSTRACT BACKGROUND Prophylactic anticoagulation helps prevent postoperative venous thromboembolism (VTE) and time to initiation postcraniotomy has relied on clinical judgment and practice patterns. OBJECTIVE To compare risks of postoperative VTE and hemorrhage among patients undergoing tumor resection with initiation of prophylactic anticoagulation on postoperative day 1 (POD1) vs POD2. METHODS Adult patients undergoing craniotomy for tumor between 2008 and 2018 were retrospectively reviewed. Outcomes were recorded from the Electronic medical record (EMR) including deep vein thrombosis (DVT), pulmonary embolism (PE), and hemorrhage. RESULTS Of a total of 1168 patients undergoing craniotomy, 225 initiated anticoagulation on POD1 and 389 initiated on POD2. Of the 171 glioblastoma (GBM) cases, 64 initiated on POD1 and 107 on POD2. There were 9 DVTs (1.5%), 1 PE (0.20%), overall VTE rate of 1.6%, and 7 hemorrhagic complications (1.10%), 4 being clinically significant. The GBM cohort contained 4 DVTs (2.3%) and 3 hemorrhagic complications (1.80%). There was no increased risk of VTE or hemorrhage with anticoagulation initiated on POD2 compared to POD1 in either cohort. Multivariate analysis in both cohorts did not reveal a significant association between DVT, PE, or hemorrhagic complications with age, body mass index, GBM pathology, or extent of resection. Interestingly, glioma patients older than 70 with subtotal resection had a higher likelihood of suffering intracranial hemorrhage when anticoagulation was started on POD1 (odds ratio 12.98). CONCLUSION Risk of VTE or hemorrhagic complication did not significantly differ with prophylactic anticoagulation started on POD1 vs POD2. Early anticoagulation may certainly be considered in high risk cases; however, 1 group where risk may outweigh benefit is the elderly glioma population receiving a subtotal resection.

Background: The management of Non-Functioning Pituitary Adenoma (NFPA) invading the cavernous sinus (CS) is currently a balancing act between the surgical decompression of neural structures, radiotherapy and a wait-and-see policy. Methods: We undertook a retrospective review of 56 cases of NFPA with CS invasion treated through an endoscopic endonasal approach (EEA) between 2000 and 2010. The Knosp classification was adopted to describe CS involvement using information from preoperative MRI and intraoperative findings. Extent of resection and surgical outcomes were evaluated on the basis of postoperative contrast-enhanced MRI. Endocrinological improvement and visual outcomes were assessed according to the most recent consensus criteria. Results: EEA was performed using direct para-septal, trans-ethmoidal-sphenoidal or trans-ethmoidal-pterygoidal-sphenoidal approach. Visual outcomes improved in 30 (81%) patients. Normalization or at least improvement of previous hypopituitarism was obtained in 55% of cases. A gross total resection was achieved in 30.3% of cases. The recurrence-free survival was 87.5%, with a mean follow-up of 61 months (range, 36-166 months). No major intraoperative or postoperative complications occurred. Discussion: EEA is a minimally-invasive, safe and effective procedure for the management of NFPA invading the CS. The extent of CS involvement was the main factor limiting the degree of tumor resection. The EEA was able to resolve the mass effect, preserving or restoring visual function, and obtaining adequate long-term tumor control.

Abstract BACKGROUND The nasoseptal flap is the main pedicled flap used for endoscopic cranial base reconstruction. For large anterior cranial base defects, the anterior edge is a concern for the nasoseptal flap reach. OBJECTIVE To present a surgical technique that completely releases the vascular pedicle of the nasoseptal flap from the sphenopalatine artery (SPA) foramen improving considerably the reach of the flap. METHODS A patient with left anterior cranial base fracture involving the posterior table of the frontal sinus, who presented with cerebrospinal fluid leak and contused brain herniation to the ethmoid and frontal sinuses. Unilateral endoscopic endonasal anterior cranial base reconstruction was performed with left sided nasoseptal flap. The nasoseptal flap pedicle was dissected and completely released from the SPA foramen. The flap was left attached only to the internal maxillary artery (IMAX) vascular bundle. RESULTS The flap covered the entire left anterior cranial base, from the planum sphenoidale to the posterior table of the frontal sinus. There was complete obliteration of the cerebrospinal fluid fistula postoperatively with resolution of the radiographic pneumocephalus and the patient's rhinorrhea. CONCLUSION The complete release of the nasoseptal flap pedicle from the SPA foramen is feasible and remarkably improves the reach of the flap. It also increases the reconstructive area of the flap since the entire septal mucosa can be used for reconstruction and the pedicle length is based exclusively upon the SPA/IMAX.

Abstract BACKGROUND: Sella and suprasellar tumors are increasingly managed via an endoscopic transsphenoidal approach, but infant endoscopic surgery has not been reported. Pituitary blastoma is a rare sellar malignant tumor that primarily occurs in infants and is managed by surgical resection (cytoreduction) followed by adjuvant therapy. OBJECTIVE: To describe the technique and feasibility of resection of a pituitary blastoma via endoscopic endonasal transsphenoidal approach in an 18-month-old infant. METHODS: Endoscopic endonasal transsphenoidal approach for resection of a pituitary malignant tumor in an infant. RESULTS: Near-total tumor resection was achieved. The skull base was reconstructed by using a nasoseptal flap with no cerebrospinal fluid leak or any other intraoperative complications. The postoperative course was uneventful. One-year follow-up showed complete resolution of the tumor. CONCLUSION: The endoscopic endonasal transsphenoidal approach with nasoseptal flap reconstruction could be used as a safe, yet minimally invasive and innovative technique for the resection of pituitary blastoma in infants.

Purpose To assess the role of residual tumor resection performed after high-dose chemotherapy (HDCT) in patients with relapsed or refractory germ cell tumors (GCT). Patients and Methods Between July 1987 and October 1999, postchemotherapy resections of residual tumors were performed in 57 patients who had been treated with HDCT for relapsed or refractory GCT and who had achieved a partial remission to this treatment. Results Complete resections of residual masses were achieved in 52 (91%) of 57 patients who were rendered disease free; in five (9%) of 57 patients, the resections were incomplete. Resection of a single site was performed in 39 (68%) of 57 patients, and the remaining 18 (32%) of 57 patients required interventions at two or more residual tumor sites. Necrosis was found in 22 (38%) of 57 patients, mature teratoma with or without necrosis was found in nine (16%) of 57 patients, and viable cancer with or without additional necrosis or mature teratoma was found in 26 (46%) of 57 patients. Viable cancer consisted either of residual germ cell or undifferentiated cancer in 22 (85%) of 26 patients, with additional non-GCT histologies in the remaining four patients. Patients with viable cancer had a significantly inferior outcome after surgery compared with patients with necrosis and/or mature teratoma even if all cancer was completely resected. Pulmonary lesions with a diameter of more than 2 cm were the only predictive variable for viable cancer in univariate analysis. Conclusion Resections of all residual tumors should be attempted in patients with relapsed or refractory GCT and partial remissions after HDCT.

Abstract INTRODUCTION Glioblastoma multiforme (GBM) is the most common brain tumor, however, is a rare occurrence in children and is poorly characterized. We evaluated the characteristics and outcomes of pediatric GBM (pGBM). METHODS Retrospective analysis of pediatric (age < 18) patients diagnosed with GBM undergoing first glioblastoma resection at our brain tumor center (2005-2016). RESULTS From 1457 GBM patients, we identified 24 (1.65%) pGBMs (Median Age = 9 yr, Females = 45.8%). Median overall survival (OS) was 32.1 mo, while the median progression-free survival was 11.5 mo. The commonest symptoms at presentation were headaches (54.2%, n = 13) and motor symptoms (50%, n = 12). Mean tumor diameter was 4.5 cm and 25% of the cohort underwent gross total resection (GTR) of their tumor. Univariate analysis revealed median OS significantly associated with tumor extent of resection (GTR = 56.4 mo; STR/Biopsy = 13.7 mo, P = .001), age at surgery (>10 yr = 43.9 mo, <10 yr = 17.2 mo, P = .01), tumor size (>4 cm = 9.1 mo, <4 cm = 56.9 mo, P = .01), motor symptoms at presentation (present = 14.9 months, absent = 41.04 mo, P = .02) and infratentorial tumors (infratentorial = 17.4 vs supratentorial = 53.4 mo, P = .02). Cox proportional hazard multivariate analysis revealed GTR (HR 0.2[95% CI 0.07-0.72]; P = .03), Age > 10 yr (HR 0.6[95% CI 0.02-0.64]; P = .002), tumor > 4 cm (HR 2.89[95% CI 1.88-4.11]; P = .001), and EGFR amplification (HR 3.48[95% CI 0.82-17.4]; P = .005) to be independent predictors of OS. Comparing patients under and over 10 yr, we found that older patients had smaller tumors at presentation (4.9 vs 3.6 cm, P = .03), greater rates of preoperative temozolomide (n = 1, 7.7% vs n = 6, 54.5%) and bevacizumab (n = 1, 7.7% vs n = 4, 36.4%) treatment, and lower rates of EGFR amplification (66.7% vs 11.1%) that could explain survival disparities among these groups. CONCLUSION Motor symptoms, larger tumors at presentation and tumor EGFR amplification may be indictive of poorer outcomes in pGBM. However, maximal tumor resection, aggressive chemoradiation, and tumor presentation at age >10 yr may confer better prognosis in these patients.

Abstract Background Recently the endoscopic endonasal surgery (EES) has been introduced as a modality for the treatment of patients with craniopharyngiomas. In this study, we describe our initial experience in treatment of 29 patients with craniopharyngiomas using this approach. Methods Twenty-nine consecutive patients with craniopharyngiomas who had undergone EES in a 5-year period were studied retrospectively. Patients underwent preoperative and postoperative endocrinologic and ophthalmologic evaluations. Radiologic characteristics of tumors and extent of resection were determined. The recurrence and complications were evaluated. Results Pituitary and visual dysfunction were observed preoperatively in 89.7 and 86% of patients, respectively. After EES, visual outcome either showed an improvement or else remained unchanged in 92.3% of the cases; however, pituitary function remained unchanged and even got worsened in 34.6% of the cases. Prevalence of diabetes insipidus before and after surgery was 58.6 and 69.2%. The rate of gross total resection was 62%. Moreover, 86.2% of the tumors were almost totally resected (more than 95% of the tumor size resected). After surgery, cerebrospinal fluid (CSF) leak and meningitis occurred in four (13.8%) and two (6.9%) patients, respectively. Perioperative mortality was seen in two of the cases (6.9%). The mean follow-up was 25 months and tumor recurrence was discovered in four patients (15.3%). Conclusion The EES with the goal of maximal and safe tumor resection could be used for the treatment of most craniopharyngiomas. Although the rates of visual improvement and gross tumor resection are high, CSF leak, pituitary dysfunction, and meningitis are serious concerns.

OBJECTIVE Craniopharyngiomas have historically been resected via transcranial microsurgery (TCM). In the last 2 decades, the extended endoscopic endonasal (transtuberculum) approach to these tumors has become more widely accepted, yet there remains controversy over which approach leads to better outcomes. The purpose of this study is to determine whether differences in outcomes were identified between TCM and extended endoscopic endonasal approaches (EEEAs) in adult patients undergoing primary resection of suprasellar craniopharyngiomas at a single institution. METHODS A retrospective review of all patients who underwent resection of their histopathologically confirmed craniopharyngiomas at the authors' institution between 2005 and 2015 was performed. Pediatric patients, revision cases, and patients with tumors greater than 2 standard deviations above the mean volume were excluded. The patients were divided into 2 groups: those undergoing primary TCM and those undergoing a primary EEEA. Preoperative patient demographics, presenting symptoms, and preoperative tumor volumes were determined. Extent of resection, tumor histological subtype, postoperative complications, and additional outcome data were obtained. Statistical significance between variables was determined utilizing Student t-tests, chi-square tests, and Fisher exact tests when applicable. RESULTS After exclusions, 21 patients satisfied the aforementioned inclusion criteria; 12 underwent TCM for resection while 9 benefitted from the EEEA. There were no significant differences in patient demographics, presenting symptoms, tumor subtype, or preoperative tumor volumes; no tumors had significant lateral or prechiasmatic extension. The extent of resection was similar between these 2 groups, as was the necessity for additional surgery or adjuvant therapy. CSF leakage was encountered only in the EEEA group (2 patients). Importantly, the rate of postoperative visual improvement was significantly higher in the EEEA group than in the TCM group (88.9% vs 25.0%; p = 0.0075). Postoperative visual deterioration only occurred in the TCM group (3 patients). Recurrence was uncommon, with similar rates between the groups. Other complication rates, overall complication risk, and additional outcome measures were similar between these groups as well. CONCLUSIONS Based on this study, most outcome variables appear to be similar between TCM and EEEA routes for similarly sized tumors in adults. The multidisciplinary EEEA to craniopharyngioma resection represents a safe and compelling alternative to TCM. The authors' data demonstrate that postoperative visual improvement is statistically more likely in the EEEA despite the increased risk of CSF leakage. These results add to the growing evidence that the EEEA may be considered the approach of choice for resection of select confined primary craniopharyngiomas without significant lateral extension in centers with experienced surgeons. Further prospective, multiinstitutional collaboration is needed to power studies capable of fully evaluating indications and appropriate approaches for craniopharyngiomas.

Object In this study the authors retrospectively review outcomes in patients treated for metastases to the spine. Surgery for metastatic tumors to the spine remains an important part of the treatment armamentarium. Maximum tumor resection with a minimum number of complications is one of the goals of surgery. Current surgical procedures include tumor resection and spinal stabilization for optimal results. Methods The records of 96 patients who underwent surgery for a metastatic spine tumor at the authors' institution were reviewed. Spinal instrumentation was used in the majority of patients. Ambulatory status was maintained in 91% and pain improved in 94% of patients. Complications included infection (5.2%), cerebrospinal fluid leak (2%), and delayed hardware failure (3.1%). The mortality rate was 4.1%; the main cause was due to tumor progression. Conclusions Surgery is indicated in a select group of patients with metastatic tumors to the spine. A multidisciplinary approach is recommended for patient selection and complication avoidance. Surgical options, including approach, type of reconstruction and extent of resection (including en bloc spondylectomy) need to be addressed for optimal outcomes.

Abstract Background Streptococcus oralis belongs to the Streptococcus mitis group and is part of the normal flora of the nasal and oropharynx (Koneman et al., The Gram-positive cocci part II: streptococci, enterococci and the ‘Streptococcus-like’ bacteria. Color atlas and textbook of diagnostic microbiology, 1997). Streptococcus oralis is implicated in meningitis in patients with decreased immune function or from surgical manipulation of the central nervous system. We report a unique case of meningitis by Streptococcus oralis in a 58-year-old patient with cerebral spinal fluid leak due to right sphenoid meningoencephalocele. Case presentation A 58-year-old female presented in the emergency department due to altered mental status, fevers, and nuchal rigidity. Blood cultures were positive for Streptococcus oralis. Magnetic resonance stereotactic imaging of head with intravenous gadolinium showed debris in lateral ventricle occipital horn and dural thickening/enhancement consistent with meningitis. There was also a right sphenoidal roof defect, and meningoencephalocele with cerebrospinal fluid leak as a result. The patient was treated with ceftriaxone and had endoscopic endonasal repair of defect. She had complete neurologic recovery 3 months later. Conclusions Cerebrospinal fluid leak puts patients at increased risk for meningitis. Our case is unique in highlighting Streptococcus oralis as the organism implicated in meningitis due to cerebrospinal fluid leak.
