Abstract
OBJECTIVE The transsphenoidal approach is the standard for most pituitary tumors. Despite low morbidity, postoperative CSF fistulas and meningitis are specific complications. Various surgical closure techniques for intraoperative CSF (iCSF) leak and sellar reconstruction have been described. For many years the authors have applied synthetic materials for iCSF leak repair and sellar closure in a standardized fashion in their department. Here they analyze the surgical outcome as well as risk factors for iCSF leak and meningitis. METHODS All patients with transsphenoidal resection of a pituitary adenoma performed by the same surgeon between January 2013 and December 2019 were screened retrospectively. A small amount of iCSF flow without a diaphragmatic defect was classified as a minor leak, and obvious CSF flow with or without a diaphragmatic defect was classified as a major leak. In case of iCSF leak, a fibrin- and thrombin-coated sponge was used to cover the diaphragmatic defect and another one was used for the sellar opening. A gelatin sponge was placed in the sphenoid sinus as an abutment. The primary and secondary outcomes were the number of postoperative CSF (pCSF) leaks and meningitis, respectively. Clinical, histological, and perioperative data from medical records were collected to identify risk factors for CSF leak and meningitis. RESULTS Of 417 transsphenoidal surgeries, 359 procedures in 348 patients with a median age of 54 years were included. There were 96 iCSF leaks (26.7%; 37.5% major, 62.5% minor). In 3 of 359 cases (0.8%) a pCSF fistula occurred, requiring revision surgery in 2 patients and a lumbar drain in 1 patient. Meningitis occurred in 3 of 359 cases (0.8%). All 3 patients recovered without sequelae after antibiotic therapy. According to univariate analysis, risk factors for iCSF leak were macroadenoma (p = 0.006) and recurrent adenoma (p = 0.032). An iCSF leak was found less often in functioning adenomas (p = 0.025). In multivariate analysis recurrent tumors remained as a risk factor (p = 0.021) for iCSF leak. Patients with iCSF leak were at increased risk for a pCSF leak (p = 0.005). A pCSF leak in turn represented the key risk factor for meningitis (p = 0.033). CONCLUSIONS Patients with macroadenomas and recurrent adenomas are especially at risk for iCSF leak. An iCSF leak in turn increases the risk for a pCSF leak, which carries the risk for meningitis. The authors' surgical technique leads to a very low rate of pCSF leaks and meningitis without using autologous graft materials. Hence, this technique is safe and improves patient comfort by avoiding the disadvantages of autologous graft harvesting.

Abstract
Endoscopic skull-base surgery (ESBS) is a rapidly growing surgical area that involves collaboration of otolaryngology-head and neck surgeons and neurosurgeons. Various tumor pathologies and extents have been successfully treated with ESBS, and diverse reconstruction methods have been adopted since its introduction. The optimal reconstructive strategy should be based on heterogeneous surgical situations and tumor extent. Nevertheless, there are few current guidelines for selecting reconstructive methods. Therefore, we review diverse options for endoscopic skull-base reconstruction.

Abstract
PURPOSE Postoperative cerebrospinal fluid rhinorrhoea (CSFR) remains a frequent complication of endonasal approaches to pituitary and skull base tumours. Watertight skull base reconstruction is important in preventing CSFR. We sought to systematically review the current literature of available skull base repair techniques. METHODS Pubmed and Embase databases were searched for studies (2000-2020) that (a) reported on the endonasal resection of pituitary and skull base tumours, (b) focussed on skull base repair techniques and/or postoperative CSFR risk factors, and (c) included CSFR data. Roles, advantages and disadvantages of each repair method were detailed. Random-effects meta-analyses were performed where possible. RESULTS 193 studies were included. Repair methods were categorised based on function and anatomical level. There was absolute heterogeneity in repair methods used, with no independent studies sharing the same repair protocol. Techniques most commonly used for low CSFR risk cases were fat grafts, fascia lata grafts and synthetic grafts. For cases with higher CSFR risk, multilayer regimes were utilized with vascularized flaps, gasket sealing and lumbar drains. Lumbar drain use for high CSFR risk cases was supported by a randomised study (Oxford CEBM: Grade B recommendation), but otherwise there was limited high-level evidence. Pooled CSFR incidence by approach was 3.7% (CI 3-4.5%) for transsphenoidal, 9% (CI 7.2-11.3%) for expanded endonasal, and 5.3% (CI 3.4-7%) for studies describing both. Further meaningful meta-analyses of repair methods were not performed due to significant repair protocol heterogeneity. CONCLUSIONS Modern reconstructive protocols are heterogeneous and there is limited evidence to suggest the optimal repair technique after pituitary and skull base tumour resection. Further studies are needed to guide practice.

[PMID: 34337683 DOI: 10.1007/s10143-021-01614-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 07/15/2021] [Accepted: 07/20/2021] [Indexed: 10/20/2022]
Abstract
Pituitary adenoma surgery has evolved rapidly in recent decades, changing clinical practice markedly and raising new challenges. There is no current consensus or guidelines for perioperative care that includes possible complication management. This study aims to determine current practice across European neurosurgical centres. We created a list of eligible departments performing pituitary adenoma surgery based on cooperation with EANS, national neurosurgical societies, and personal communication with local neurosurgeons. We contacted the chairpersons from each department and asked them (or another responsible neurosurgeon) to fill out the survey. The survey consisted of 58 questions. For further analysis, departments were divided into subgroups: "academic"/ "non-academic centre", "high-volume"/"low-volume", "mainly endoscopic"/ "mainly microscopic"/ "mixed practise", and by geographical regions. Data from 254 departments from 34 countries were obtained. The average time to complete the survey was 18 min. Notably, the endoscopic approach is the predominant surgical approach in Europe, used in 56.8% of the centres. In routine cases without intraoperative cerebrospinal fluid leak, high-volume centres are less pedantic with sellar closure when compared with low-volume centres (p < 0.001). On the other hand, when a postoperative cerebrospinal fluid leak occurs, high-volume centres are more active and indicate early reoperation (p = 0.013). Less than 15% of the participating centres perform early postoperative MRI scans. Marked variation was noted among different groups of respondents and some contentious issues are discussed. Such information can encourage useful debate about the reasons for the variations seen and perhaps help develop standardised protocols to improve patient outcomes. A future research focus is to compare European results with other regions.

Abstract
BACKGROUND The transsphenoidal approach is the standard of care for the treatment of pituitary adenomas and is increasingly employed for many anterior skull base tumors. Persistent postoperative cerebrospinal fluid (CSF) leaks can result in significant complications. OBJECTIVE To analyze our series of patients undergoing abdominal fat graft repair of the sellar floor defect following transsphenoidal surgery, describe and investigate our current, routine technique, and review contemporary and past methods of skull base repair. METHODS A recent consecutive series (2008-2017) of 865 patients who underwent 948 endonasal procedures for lesions of the sella and anterior skull base was retrospectively reviewed. Three hundred eighty patients underwent reconstruction of the sellar defect with an abdominal fat graft. RESULTS The diagnoses of the 380 patients receiving fat grafts were the following: 275 pituitary adenomas (72.4%), 50 Rathke cleft cysts (13.2%), 12 craniopharyngiomas (3.2%), and a variety of other sellar lesions. Fourteen patients had persistent postoperative CSF leak requiring reoperation and included: 5 pituitary adenomas (1.3%), 4 craniopharyngiomas (1.1%), 2 arachnoid cysts (0.53%), 2 prior CSF leaks (0.53%), and 1 Rathke cleft cyst (0.26%). Four patients (1.1%) developed minor abdominal donor site complications requiring reoperation: 1 hematoma, 2 wound complications, and 1 keloid formation resulting in secondary periumbilical infection. CONCLUSION Minimizing postoperative CSF leaks following endonasal anterior skull base surgery is important to decrease morbidity and to avoid a prolonged hospital stay. We present an evolved technique of abdominal fat grafting that is effective and safe and includes minimal morbidity and expense.

Abstract
Background and Objectives: Following the transsphenoidal approach (TSA), appropriate sphenoid sinus fat packing has been preferred to prevent postoperative cerebrospinal fluid leakage; however, studies on the behavior of fat tissue transplanted in the sphenoid sinus are lacking. This study aimed to determine the long-term fate of these fat grafts using magnetic resonance imaging (MRI).Subjects and Method: A total of 139 postoperative MRI scans of 41 patients who underwent sphenoid sinus fat packing using the standard TSA were evaluated. Additionally, MRI time series indicating the vital fat volumes were assessed postoperatively.Results: In 82.9% of cases, the fat volumes measured in the final MRI scans declined to <20% of the initial volumes; only 4.9% of cases exhibited declines to >60% of the initial volume. The fat tissue volume decreased significantly with time, with a median half-life of 18 months. Typically, the sphenoid sinus was eventually almost filled with air rather than transplanted fat. In the subgroup analysis, the fat clearance rate was significantly lower in patients with residual tumors than in those without such remnants (p=0.013).Conclusion: Long-term MRI surveillance of fat grafts in the sphenoid sinus revealed that the transplanted fat graft had degraded and was gradually eliminated.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
INTRODUCTION Multiple options exist for sellar reconstruction after endoscopic transnasal, transsphenoidal surgery (TSS) including free mucosa, fat, bone and synthetic materials. The objective of this study was to assess healing and mucosalization of the sellar face following TSS without formal sellar grafting or reconstruction. METHODS Single institution retrospective chart review was conducted for patients undergoing TSS without intraoperative CSF leaks between January 2014 and March 2017 at Rush University Medical Center. No formal sellar reconstruction was performed for the entire patient group. Follow-up endoscopic data and clinical notes were coded for time to mucosalization of the sella as well as degree of abnormal mucosal healing, epistaxis, crusting and scarring. RESULTS 83 patients were included in this study. Mean time to mucosalization was 119 days (range, 17 to 402 days). Incidence of abnormal mucosal healing, epistaxis, crusting and scarring increased from the first to the second postoperative visit but trended down by the third visit. Nasal crusting was the most common finding, followed by abnormal mucosal healing. Chi square analysis showed smoking to be associated with prolonged time to full mucosalization of the sella. Two patients (2.4%) had post-operative CSF leaks requiring lumbar drain placement. CONCLUSION Adequate sellar healing is achievable in all cases without formal grafting or reconstruction after TSS. Great care must be exercised given the small inherent risk of unmasking a subclinical intraoperative CSF leak. Patients should be followed closely endoscopically during the first four months after TSS to minimize the impact of crusting.

Transclival approaches for intradural pathologies: historical overview and present scenario. Neurosurg Rev 2020; 44:279-287.

Abstract
Recently, endoscopic transsphenoidal transclival approaches have been developed and their role is widely accepted for extradural pathologies. Their application to intradural pathologies is still debated, but is undoubtedly increasing. In the past five decades, different authors have reported various extracranial, anterior transclival approaches for intradural pathologies. The aim of this review is to provide a historical overview of transclival approaches applied to intradural pathologies. PubMed was searched in October 2018 using the terms transcliv*, cliv* intradural, transsphenoidal transcliv*, transoral transcliv*, transcervical transcliv*, transsphenoidal brainstem, and transoral brainstem. Exclusion criteria included not reporting reconstruction technique, anatomical studies, reviews without new data, and transcranial approaches. Ninety-one studies were included in the systematic review. Since 1966, transcervical, transoral, transsphenoidal microsurgical, and, recently, endoscopic routes have been used as a corridor for transclival approaches to treat intradural pathologies. Each approach presents a curve that follows Scott's parabola, with evident phases of enthusiasm that quickly faded, possibly due to high post-operative CSF leak rates and other complications. It is evident that the introduction of the endoscope has led to a significant increase in reports of transclival approaches for intradural pathologies. Various reconstruction techniques and materials have been used, although rates of CSF leak remain relatively high. Transclival approaches for intradural pathologies have a long history. We are now in a new era of interest, but achieving effective dural and skull base reconstruction must still be definitively addressed, possibly with the use of newly available technologies.

Abstract
Postoperative cerebrospinal fluid (CSF) leak still represents the main limitation of endonasal endoscopic surgery. The aim of the study is to classify the risk of postoperative leak and to propose a decision-making protocol to be applied in the preoperative phase based on radiological data and on intraoperative findings to obtain the best closure.One hundred fifty-two patients were treated in our institution; these patients were divided into 2 groups because from January 2013 the closure technique was standardized adopting a preoperative decision-making protocol. The Postoperative CSF leak Risk Classification (PCRC) was estimated taking into account the size of the lesion, the extent of the osteodural defect, and the presence of intraoperative CSF leak (iCSF-L). The closure techniques were classified into 3 types according to PCRC estimation (A, B, and C).The incidence of the use of a nasoseptal flap is significantly increased in the second group 80.3% versus 19.8% of the first group and the difference was statistically significant P < 0.0001. The incidence of postoperative CSF leak (pCSF-L) in the first group was 9.3%. The incidence of postoperative pCSF-L in the second group was 1.5%. An analysis of the pCSF-L rate in the 2 groups showed a statistically significant difference P = 0.04.The type of closure programmed was effective in almost all patients, allowing to avoid the possibility of a CSF leak. Our protocol showed a significant total reduction in the incidence of CSF leak, but especially in that subgroup of patients where a leak is usually unexpected.

Abstract
OBJECTIVE The Medpor porous polyethylene implant is reported to be safe and effective for sellar reconstruction after transsphenoidal surgery (TSS). However, we have observed several cases of delayed chronic sphenoid sinusitis related to the implant. The purpose of this study is to describe the presentation and management of implant-related sphenoid sinusitis after sellar reconstruction. METHODS This is a retrospective study of patients who underwent endonasal TSS with Medpor sellar reconstruction between December 2008 and January 2013 at a tertiary care institution. Patient demographics, initial surgical management, sinonasal symptoms, postoperative imaging, sinusitis management, and resulting outcomes were analyzed. RESULTS From 2008-2013, 139 patients underwent sellar reconstruction using Medpor. Five patients (3.6%) presented between 8 and 60 months after surgery with chronic sphenoid sinusitis that required surgical management. All 5 patients presented as outpatients for management of headaches and nasal drainage, 4 patients experienced chronic nasal congestion, and 3 patients noted recurrent sinusitis. At the time of revision surgery, all 5 patients were found to have mucosal inflammation and edema surrounding the implant, and 4 of the 5 had an exposed or partially extruded implant that was removed. CONCLUSIONS Reconstruction of the sellar floor may be performed after TSS to prevent postoperative complications. Although porous polyethylene implants have previously been described as safe and effective for this purpose, surgeons should be aware of the risk of subsequent implant extrusion and chronic sphenoid sinusitis that can occur in a delayed manner.

Abstract
Objectives
This article aims (1) to determine whether there is any difference in cerebrospinal fluid (CSF) leak rate after anterior skull base autologous fat reconstruction based on how the fat is prepared, and (2) to measure impact on surgical times by reconstruction type.
Design
Translational animal model surgical technique 3-arm trial, comparing two different methods of autologous fat skull base reconstruction versus a nonreconstructed control group.
Setting
Animal study.
Subjects
Adult Sprague-Dawley rats.
Main Outcome Measures
Resolution of CSF rhinorrhea after repair of a surgically created anterior skull base defect.
Results
Both wet (uncompressed) and dry (compressed) fat reconstruction of an anterior skull base defect demonstrated lower CSF leak rates than nonreconstructed defects. Dry fat reconstruction achieved significance in superiority of controlling CSF leak over no reconstruction (64% success vs. 31%); while wet fat reconstruction trended toward significance (50% vs. 31%). Reconstruction procedure time was longer than nonreconstructed controls, but there was no significant difference between type of fat preparation in surgical time.
Conclusions
This study demonstrates that drying and compressing the fat graft improves autologous fat reconstruction success for anterior skull base defects, and does not add significantly to surgical time over nonprepared fat.

Transsphenoidal pituitary surgery: comparison of two sellar reconstruction techniques and their effect on postoperative cerebrospinal fluid leakage. Neurosurg Rev 2018; 41:1053-1058. [PMID: 29388119 DOI: 10.1007/s10143-018-0949-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Revised: 12/18/2017] [Accepted: 01/22/2018] [Indexed: 10/18/2022]
Abstract
Transsphenoidal surgery is a common procedure in patients with pituitary adenomas. Several techniques have been previously postulated to achieve sufficient sellar reconstruction to avoid cerebrospinal fluid (CSF) leakage. We analyzed our institutional database concerning two sellar reconstruction techniques and development of postoperative CSF leakage. From 2009 to 2015, 255 patients underwent transsphenoidal pituitary surgery at our institution. According to the technique used for sellar reconstruction, patients were divided into two groups: (1) with muscle patch and fibrin glue and (2) with fibrin glue alone. Postoperative CSF leakage occurred in 7% of the patients. Occurrence of postoperative CSF leakage did not differ significantly between both sellar reconstruction techniques (p = 0.2). Patients who underwent sellar reconstruction with fibrin glue alone had significantly shorter operating time (p < 0.0001), as well as shorter length of hospital stay (p = 0.01). On multivariate analysis, occurrence of intraoperative CSF leakage was the only predictor for postoperative CSF leakage (p < 0.0001). The present data suggests that sellar reconstruction after transsphenoidal pituitary surgery seems to be equally effective in preventing postoperative CSF leakage. However, the use of fibrin glue alone results in shorter hospital stay and operating time without exposing patients to more frequent CSF leakage.

Abstract
Abstract
BACKGROUND
Postoperative cerebrospinal fluid (CSF) leak is a persistent, albeit much less prominent, complication following endonasal endoscopic surgery. The pathology with highest risk is suprasellar meningiomas. A postoperative lumbar drain (LD) is used to decrease the risk of CSF leak but is not universally accepted.
OBJECTIVE
To compare the rates of postoperative CSF leak between patients with and without LD who underwent endonasal endoscopic surgical resection of suprasellar meningiomas.
METHODS
A consecutive series of newly diagnosed suprasellar meningiomas was drawn from a prospectively acquired database of endonasal endoscopic surgeries at our institution. An intraoperative, preresection LD was placed and left open at 5 cc/h for ∼48 h. In a subset of patients, the LD could not be placed. Rates of postoperative CSF leak were compared between patients with and without an LD.
RESULTS
Twenty-five patients underwent endonasal endoscopic surgical resection of suprasellar meningiomas. An LD could not be placed in 2 patients. There were 2 postoperative CSF leaks (8%), both of which occurred in the patients who did not have an LD (P = .0033). The average body mass index (BMI) of the patients in whom the LD could not be placed was 39.1 kg/m2, compared with 27.6 kg/m2 for those in whom the LD could be placed (P = .009). In the subgroup of obese patients (BMI > 30 kg/m2), LD placement was protective against postoperative CSF leak (P = .022).
CONCLUSION
The inability to place an LD in patients with obesity is a risk factor for postoperative CSF leak. An LD may be useful to prevent postoperative CSF leak, particularly in patients with elevated BMI.

Fibrin Sealants in Dura Sealing: A Systematic Literature Review. PLoS One 2016; 11:e0151533. [PMID: 27119993 PMCID: PMC4847933 DOI: 10.1371/journal.pone.0151533] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2015] [Accepted: 02/28/2016] [Indexed: 01/06/2023] Open
Abstract
Background Fibrin sealants are widely used in neurosurgery to seal the suture line, provide watertight closure, and prevent cerebrospinal fluid leaks. The aim of this systematic review is to summarize the current efficacy and safety literature of fibrin sealants in dura sealing and the prevention/treatment of cerebrospinal fluid leaks. Methods A comprehensive electronic literature search was run in the following databases: Cochrane Database of Systematic Reviews, Cochrane Central Resister of Controlled Trials, clinicaltrials.gov, MEDLINE/PubMed, and EMBASE. Titles and abstracts of potential articles of interest were reviewed independently by 3 of the authors. Results A total of 1006 database records and additional records were identified. After screening for duplicates and relevance, a total of 78 articles were assessed by the investigators for eligibility. Thirty-eight were excluded and the full-text of 40 articles were included in the qualitative synthesis. Seven of these included only safety data and were included in the safety assessment. The remaining 33 articles included findings from 32 studies that enrolled a total of 2935 patients who were exposed to fibrin sealant. Among these 33 studies there were only 3 randomized controlled trials, with the remaining being prospective cohort analysis, case controlled studies, prospective or retrospective case series. One randomized controlled trial, with 89 patients exposed to fibrin sealant, found a greater rate of intraoperative watertight dura closure in the fibrin sealant group than the control group (92.1% versus 38.0%, p<0.001); however, post-operative cerebrospinal fluid leakage occurred in more fibrin sealant than control patients (6.7% versus 2.0%, p>0.05). Other clinical trials evaluated the effect of fibrin sealant in the postoperative prevention of cerebrospinal fluid leaks. These were generally lower level evidence studies (ie, not prospective, randomized, controlled trials) that were not designed or powered to demonstrate a significant advantage to fibrin sealant use. Two small case series studies evaluated the effect of fibrin sealants in persistent cerebrospinal fluid leak treatment, but did not establish firm efficacy conclusions. Specific adverse reports where fibrin sealants were used for dura sealing were limited, with only 8 cases reported in neurosurgical procedures since 1987 and most reporting only a speculative relationship/association with fibrin sealant exposure. Conclusions A major finding of this systematic literature review is that there is a paucity of randomized studies that have evaluated the effectiveness and safety of fibrin sealants in providing intraoperative watertight dura closure and post-operative cerebrospinal fluid leakage. Among the limited studies available, evidence from a single randomized, controlled trial indicates that fibrin sealants provide a higher rate of intraoperative watertight closure of the dura suture line than control, albeit with a higher rate of postoperative cerebrospinal fluid leakage. Evidence from non-randomized, controlled trials suggests that fibrin sealants may be effective in preventing cerebrospinal fluid leaks with an acceptable safety profile. There is a substantial need for randomized, controlled clinical trials or well-designed prospective observational trials where the conduct of a randomized trial is not feasible to fully assess the impact of fibrin sealant utilization on the rates of intraoperative dura closure, postoperative cerebrospinal leakage, and safety.

Abstract
We aimed to evaluate combined use of atelocollagen sheet and fibrin glue for sellar reconstruction. Experiment 1: A plastic chamber was prepared with a hydroxyapatite lid with a hole of 10mm in diameter at its center, covered with a Gore-Tex sheet (W.L. Gore & Associates, Tokyo, Japan) 15mm in diameter and sealed with a combination of fibrin glue sealant and either atelocollagen sheet or polyglycolic acid (PGA) sheet. Air was injected into the chamber and the pressure at which air leakage occurred was measured under each situation. Mean (±standard deviation) leakage pressure was 816±162mmH2O for atelocollagen sheet (n=5), significantly higher than the 557±130mmH2O for PGA sheet (n=5, p<0.05, Wilcoxon test). Experiment 2: Bilateral 5mm bone windows were made in the temporal bone in eight rats. The surgical cavities were filled with one of four materials (fibrin glue only; fibrin glue and atelocollagen sheet; PGA sheet; or autologous fat tissue). Histological changes including the status of implanted materials and inflammatory responses were investigated 2 and 5weeks after the procedures. Both atelocollagen and PGA sheets remained at 5weeks after implantation, whereas fibrin glue and fat tissue were absorbed and undetectable at 2weeks. Inflammatory cell accumulation was less around the atelocollagen sheet compared to the PGA sheet. The combination of atelocollagen sheet and fibrin glue sealant showed sufficient adhesion force and favorable tissue affinity, suggesting this combination as a feasible material in sellar reconstruction.

Abstract
Anterior skull base defects with encephalocele in adults are quite rare and can be a cause of spontaneous rhinoliquorrhea; however, cerebrospinal fluid (CSF) fistula can be not rarely misdiagnosed for several months or years. Five adult patients affected by ethmoidal encephalocele with CSF fistula were treated in our institute from 2006 through to 2011. Onset of clinical history was represented by rhinoliquorrhea, which was precociously recognized in only 1 patient; in the other 4, it was misdiagnosed for a period ranging from 11 months to 5 years. After clinical diagnosis of CSF fistula and after brain magnetic resonance imaging, ethmoidal encephalocele was evident in all patients; preoperative study was completed by spiral computed tomography scan, to clearly identify the skull base bone defect. All patients were operated on by transsphenoidal endonasal endoscope-assisted microsurgical approach through 1 nostril. The herniated brain was coagulated and removed, and reconstruction of cranial base was performed. Postoperative rhinoliquorrhea or other complications did not occur in any patient at short and late follow-up. All patients were discharged after a few days. Endonasal endoscope-assisted microsurgical approach was effective in exposing and repairing the ethmoidal bone defect; tridimensional vision and wide lateral and superior exposition of the operative field were possible in each patient, thanks to the use of microscope and angulated endoscope.

Abstract
OBJECTIVE Complete sellar floor reconstruction is critical to avoid postoperative cerebrospinal fluid (CSF) leakage during transsphenoidal surgery. Recently, the pedicled nasoseptal flap has undergone many modifications and eventually proved to be valuable and efficient. However, using these nasoseptal flaps in all patients who undergo transsphenoidal surgery, including those who had none or only minor CSF leakage, appears to be overly invasive and time-consuming. METHODS Patients undergoing endoscopic endonasal transsphenoidal tumor surgery within a 5 year-period were reviewed. Since 2009, we classified the intraoperative CSF leakage into grades from 0 to 3. Sellar floor reconstruction was tailored to each leak grade. We did not use any tissue grafts such as abdominal fat and did not include any procedures of CSF diversions such as lumbar drainage. RESULTS Among 200 cases in 188 patients (147 pituitary adenoma and 41 other pathologies), intraoperative CSF leakage was observed in 27.4% of 197 cases : 14.7% Grade 1, 4.6% Grade 2a, 3.0% Grade 2b, and 5.1% Grade 3. Postoperative CSF leakage was observed in none of the cases. Septal bone buttress was used for Grade 1 to 3 leakages instead of any other foreign materials. Pedicled nasoseptal flap was used for Grades 2b and 3 leakages. Unused septal bones and nasoseptal flaps were repositioned. CONCLUSION Modified classification of intraoperative CSF leaks and tailored repair technique in a multilayered fashion using an en-bloc harvested septal bone and vascularized nasoseptal flaps is an effective and reliable method for the prevention of postoperative CSF leaks.

Abstract
Objectives Delayed cerebrospinal fluid (CSF) leaks are a complication in transsphenoidal surgery, potentially causing morbidity and longer hospital stays. Sella reconstruction can limit this complication, but is it necessary in all patients? Design Retrospective review. Setting Single-surgeon team (2005-2012) addresses this trend toward graded reconstruction. Participants A total of 264 consecutive patients with pituitary adenomas underwent endoscopic transsphenoidal resections. Sellar defects sizable to accommodate a fat graft were reconstructed. Main outcomes Delayed CSF leak and autograft harvesting. Results Overall, 235 (89%) had reconstruction with autograft (abdominal fat, septal bone/cartilage) and biological glue. Delayed CSF leak was 1.9%: 1.7%, and 3.4% for reconstructed and nonreconstructed sellar defects, respectively (p = 0.44). Complications included one reoperation for leak, two developed meningitis, and autograft harvesting resulted in abdominal hematoma in 0.9% and wound infection in 0.4%. Conclusion In our patients, delayed CSF leaks likely resulted from missed intraoperative CSF leaks or postoperative changes. Universal sellar reconstruction can preemptively treat missed leaks and provide a barrier for postoperative changes. When delayed CSF leaks occurred, sellar reconstruction often allowed for conservative treatment (i.e., lumbar drain) without repeat surgery. We found universal reconstruction provides a low risk of delayed CSF leak with minimal complications.

Sellar Floor Reconstruction with the Medpor Implant Versus Autologous Bone After Transnasal Transsphenoidal Surgery: Outcome in 200 Consecutive Patients. World Neurosurg 2015; 84:240-5. [PMID: 25731796 DOI: 10.1016/j.wneu.2015.02.025] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2014] [Revised: 02/13/2015] [Accepted: 02/15/2015] [Indexed: 11/23/2022]
Abstract
OBJECTIVE The Medpor porous polyethylene implant provides benefits to perform sellar floor reconstruction when indicated. This material has been used for cranioplasty and reconstruction of skull base defects and facial fractures. We present the most extensive use of this implant for sellar floor reconstruction and document the safety and benefits provided by this unique implant. METHODS The medical charts for 200 consecutive patients undergoing endonasal transsphenoidal surgery from April 2008 through December 2011 were reviewed. Material used for sellar floor reconstruction, pathologic diagnosis, immediate inpatient complications, and long-term complications were documented and analyzed. Outpatient follow-up was documented for a minimum of 1-year duration, extending in some patients up to 5 years. RESULTS Of the 200 consecutive patients, 136 received sellar floor cranioplasty using the Medpor implant. Postoperative complications included 6 complaints of sinus irritation or drainage, 1 postoperative cerebrospinal fluid leak requiring operative re-exploration, 1 event of tension pneumocephalus requiring operative decompression, 1 case of aseptic meningitis, 1 subdural hematoma, and 1 case of epistaxis. The incidence of these complications did not differ from the autologous nasal bone group in a statistically significant manner. CONCLUSIONS Sellar floor reconstruction remains an important part of transsphenoidal surgery to prevent postoperative complications. Various autologous and synthetic options are available to reconstruct the sellar floor, and the Medpor implant is a safe and effective option. The complication rate after surgery is equivalent to or less frequent than other methods of reconstruction and the implant is readily incorporated into host tissue after implantation, minimizing infectious risk.

Abstract
The prevention of cerebrospinal fluid (CSF) leakage is a key feature of the transsphenoidal approach (TSA) to the pituitary fossa. Although fibrin-coated collagen fleece (Tachosil, Nycomed, Linz, Austria) is a powerful topical hemostatic agent whose usage is increasing in open neurosurgery, the use of Tachosil in TSA surgery has not yet gained wide clinical acceptance. We retrospectively evaluated whether the lone use of Tachosil without additional packing material or postoperative lumbar drainage was effective to prevent CSF leakage in TSA surgery in 101 patients. Additionally, we compared it to a conventional sellar closure technique in 54 patients. Only two (1.9%) of the patients in the Tachosil application group developed postoperative CSF rhinorrhea. No other postoperative complications occurred, including infection or material detachment. However, in the conventional packing group, five (9.3%) patients developed postoperative CSF rhinorrhea and one (1.9%) developed meningitis during the postoperative period. The mean length of postoperative hospital stay was significantly shorter in the Tachosil treatment group than in the standard closure group. These results may indicate that sellar repair using Tachosil can be effective to prevent CSF leakage after TSA surgery, and obviate the need for an autologous tissue graft or postoperative lumbar drainage.

Abstract
Background The hemi-transeptal (Hemi-T) approach was developed to facilitate a binasal two-surgeon endoscopic approach for sellar tumors, with preservation of the nasoseptal flap and selective mobilization for reconstruction. Methods A retrospective case-control study was performed comparing the Hemi-T approach with previously used methods of sellar exposure and reconstruction. Outcome measures included operative time and postoperative nasal morbidity. Results A total of 23 patients underwent the Hemi-T approach versus 42 in whom traditional exposure was performed. Operative time was significantly shorter using the Hemi-T technique (152.6 ± 56.8 versus 205.2 ± 61.3 minutes; p = 0.001), as was the length of hospital stay (3.3 ± 1.9 versus 5.4 ± 3.6 days; p = 0.004). There was no difference in the rates of intraoperative or postoperative cerebrospinal fluid leak, cartilage necrosis, septal perforation, or mucosal adhesions. Conclusion The Hemi-T approach facilitates binasal two-surgeon access to the sella without compromise of the pedicle during the extended sphenoidotomies and tumor removal. Operative time and nasal morbidity is not increased, and iatrogenic injury to the nasal cavity is minimized when a flap is not required.

Incidence and significance of intraoperative cerebrospinal fluid leak in endoscopic pituitary surgery using intrathecal fluorescein. World Neurosurg 2013; 82:e513-23. [PMID: 23811068 DOI: 10.1016/j.wneu.2013.06.005] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2013] [Revised: 03/28/2013] [Accepted: 06/18/2013] [Indexed: 11/16/2022]
Abstract
OBJECTIVE The true rate of intraoperative cerebrospinal fluid (iCSF) leak during pituitary surgery is not well known because small iCSF leaks are easily missed. Our objective is to determine the rate and significance of iCSF leak in endoscopic pituitary surgery with intrathecal (IT) fluorescein administration and determine factors predictive of iCSF leak. METHODS IT fluorescein was administered in 203 consecutive endoscopic, endonasal pituitary surgeries. The rate of iCSF leak was noted prospectively and correlated with tumor diameter and volume, gross total resection, and the learning curve. Postoperative CSF leak rate, complications, and nasoseptal flap utility were also investigated. RESULTS The rate of iCSF leak was 61% overall, 44% for tumors<2 cm compared to 72% for tumors≥2 cm and 35% for tumors<1.5 cm3 compared to 68% for those≥1.5 cm3 (P<0.001). Postoperative CSF leak was significantly lower after the first 50 cases (0.7% vs. 10%; P<0.005) with overall leak of 3%. For tumors>2 cm, the introduction of nasoseptal flap reduced the rate of postoperative CSF leak from 5.6% to 1.4%. We did not find any complications clearly related with the use of IT fluorescein. CONCLUSION The rate of iCSF leak during endoscopic pituitary surgery using IT fluorescein is higher than previously reported. Tumor diameter and volume are best predictors of the risk of iCSF leak. Based on this knowledge and a closure algorithm that includes a lumbar drain and nasoseptal flap for larger tumors (>2.5 cm), we can conclude that the postoperative CSF leak rate remains exceptionally low, particularly once the learning curve is overcome.

Abstract
Objectives Our practice has transitioned from using fat autograft to acellular dermal matrix (AlloDerm, LifeCell Corp, Woodlands, Texas, USA). We present the largest series to our knowledge of AlloDerm for sellar floor repair after transsphenoidal approach to pituitary adenoma and compare rates of postoperative cerebrospinal fluid (CSF) leak with an earlier cohort of patients whose CSF leaks were repaired with fat autograft. Design This is a retrospective cohort study comparing sellar repair with fat autograft versus inlay Alloderm between the years 2003 and 2012. The primary end point was postoperative CSF leak. Results A total of 429 patients (368 primary; 83 revision operations) without intraoperative lumbar drainage were included. A total of 18 postoperative CSF leaks were observed (3.9%). Intraoperative CSF leak occurred in 160 cases (35.5%). Among this subset of patients with intraoperative CSF leak, 95 underwent repair with AlloDerm and 46 underwent repair with fat autograft, with postoperative CSF leak rates of 8.4% and 15.2%, respectively (p = 0.34, chi-square test); 19 patients underwent repair with other techniques or no repair at all, with postoperative leak rate of 0%. Conclusions AlloDerm is an effective alternative to fat autograft in cases of low-flow CSF leak following transsphenoidal resection of pituitary adenoma.

Abstract
Postoperative cerebrospinal fluid (CSF) leakage is one of the most common and aggravating complications in transsphenoidal surgery. Although primary closure of the fistula would be the most desirable solution for an intraoperatively encountered CSF leak, it is difficult to achieve in such a deep and narrow operative field. In this article, the authors report endonasal endoscopic applications of no-penetrating titanium clips to repair a CSF fistula following tumor removal. The AnastoClip Vessel Closure System (VCS; LeMaitre Vascular, Boston, MA) was used for closure of a CSF fistula in endonasal transsphenoidal surgery. In all four patients, CSF leakage was successfully obliterated primarily with two to five clips. There was no postoperative CSF rhinorrhea or complications related to the use of the VCS. Metal artifact by the clips on postoperative images was tolerable. Primary closure of the fistula using the VCS was an effective strategy to prevent postoperative CSF leakage in transsphenoidal surgery. Future application can be expanded to reconstruction of the skull base dura via endonasal skull base approaches.

Abstract
OBJECTIVE The aim of this study was to assess the safety and efficacy of radiation-sterilized allografts of iliac bone and fascia lata from cadaver specimens to repair skull base defects after transsphenoidal surgery. METHODS Between May 2009 and January 2010, 31 consecutive patients underwent endonasal transsphenoidal surgery and all patients received sellar reconstruction using allografts following tumor removal. The allografts were obtained from the local tissue bank and harvested from cadaver donors. The specimens used in our approach were tensor fascia lata and the flat area of iliac bone. For preparation, allografts were treated with gamma irradiation after routine screening by culture, and then stored at -70℃. RESULTS The mean follow-up period after surgery was 12.6 months (range, 7.4-16 months). Overall, postoperative cerebrospinal fluid (CSF) leaks occurred in three patients (9.7%) and postoperative meningitis in one patient (3.2%). There was no definitive evidence of wound infection at the routine postoperative follow-up examination or during re-do surgery in three patients. Postoperative meningitis in one patient was improved with the use of antibiotics and prolonged CSF diversion. CONCLUSION We suggest that allograft materials can be a feasible alternative to autologous tissue grafts for sellar reconstruction following transsphenoidal surgery under selected circumstances such as no or little intraoperative CSF leaks.

Abstract
Cerebrospinal fluid (CSF) rhinorrhea is the most common complication after transsphenoidal pituitary surgery. The authors compare their previous experience using an autologous fat graft and lumbar drain placement in 107 patients with their current technique of using a dural sealant and collagen matrix in 97 patients to prevent postoperative CSF leak after pituitary tumor resection. The failure rate for CSF leak repairs between the two groups was similar. The use of a dural sealant and collagen matrix, however, has the advantages of decreased length of hospital stay, decreased length of Intensive Care Unit stay, avoidance of the morbidity of an extra abdominal incision, and avoidance of the risks of lumbar CSF drainage.

Abstract
BACKGROUND Autologous tissue grafting and postoperative lumbar cerebrospinal fluid (CSF) drainage (PLD) have been used to prevent CSF rhinorrhea after transsphenoidal surgery. OBJECTIVE To describe the technical details and efficacy of our techniques of using collagen fleece coated with fibrin sealant (TachoComb, Nycomed, Linz, Austria) instead of an autologous tissue graft and refraining from the use of PLD. METHODS We retrospectively reviewed 307 consecutive patients who underwent a transsphenoidal surgery for pituitary adenoma from November 2005 to February 2008. Among them, 90 cases of intraoperative CSF leaks were repaired with TachoComb without an autologous tissue graft or PLD. The repair procedures were tailored according to CSF leakage type, and we used only Bioglue (Cryolife Inc, Atlanta, Georgia) for sellar floor reconstruction. RESULTS The overall rate of CSF rhinorrhea was 2.2% (2 of 90 cases). The 2 cases of CSF rhinorrhea resulted from large arachnoid defects, and there were no adverse effects from TachoComb such as transmission of viral disease or infection. CONCLUSION Our technique is an alternative method to the traditional autologous tissue graft technique. PLD is not an essential procedure for the prevention of CSF rhinorrhea if the intraoperative CSF leak is completely sealed off during the transsphenoidal surgery. However, in cases of large arachnoid defects, aggressive repair of the arachnoid defect and sellar floor reconstruction with bone or bony substitutes should be considered in conjunction with our methods.

Abstract
BACKGROUND Nonvascularized autologous grafts used for sellar reconstruction in transseptal transsphenoidal surgery are commonly applied in the setting of intraoperative cerebrospinal fluid (CSF) leak and have been shown to be effective in preventing postoperative complications. OBJECTIVE To assess the clinical implications of intraoperative CSF leak, to evaluate the efficacy of repair techniques using autologous nonvascularized materials, and to analyze the nature and timing of failures. These data may serve as a basis for assessing the utility of innovations in techniques and implant technologies. METHODS A review was conducted of 257 consecutive patients who underwent transsphenoidal surgery that was complicated by intraoperative CSF leak from 1995 to 2001. Sellar reconstruction was performed with autologous materials except in reoperations in which septal materials were not available; lumbar drain catheters were used selectively. RESULTS Six of the 257 patients (2.3%) developed postoperative CSF rhinorrhea occurring an average of 6.6 days after surgery. All 6 underwent reoperation, with 5 of 6 managed with operative lumbar drainage. Bacterial meningitis developed in 3 of 257 (1.2%). Worsening in visual function occurred in 8 of 257 (3.1%), with 1 of 257 (0.3%) suffering from permanent worsening of visual function. Additional surgery was performed in 2 of these patients, resulting in successful reversal of visual loss. Ten of 257 patients (3.9%) developed a subcutaneous hematoma at the fat graft harvest site, with 1 patient requiring surgical re-exploration. CONCLUSIONS Watertight closure of the sella with autologous materials is effective in preventing postoperative rhinorrhea. Complications specific to the technique include graft site hematoma (4%) and rare instances of visual loss caused by optic nerve compression.

Abstract
OBJECTIVE The objective of this study is to report our experience and illustrate our technique in the use of fibrin glue in the treatment of post-operatory cerebrospinal fluid (CSF) leaks and collections following different neurosurgical procedures. METHODS In a 3-year period, 40 subjects underwent endoscopic endonasal approach for different sellar and skull base lesions (three tuberculum sellae meningiomas, six craniopharyngiomas, three Rathke's cleft cysts and 28 pituitary macroadenomas), in which an intraoperative CSF leakage was evident. In such subjects, the fibrin glue was used as a first step of the final phase of the procedure-i.e. the reconstruction of the skull base defect-followed by the other materials employed. Furthermore, ten other patients, who had undergone transsphenoidal (four cases), spinal (two cases), posterior fossa (three cases) and transcortical intraventricular tumour removal (one case) neurosurgical procedures and developed CSF leaks or collections, were conservatively treated by single or repeated in situ injections of "modified" fibrin glue under local anaesthesia according to different described techniques. In total, 50 patients constitute the clinical material of the present study. TECHNIQUE In the cases where the fibrin glue was used during the reconstruction phase of the procedure (40 cases), the glue was injected inside the tumour cavity to fill the dead space left by the removal of the lesion. In case of post-operative CSF leak or CSF fluid collection (ten cases), after discarding 50-80% of the thrombin solution to obtain prevalence of the product's adhesive properties, fibrin glue was injected directly in the path of the CSF leak or into the collection cavity after aspiration of the collection's content. This was performed with the provided application system or through lumbar or Tuohy needles. Applications were repeated every 48 h until the disappearance of the leak. In all the treated cases, the disappearance of CSF leaks or collections was obtained with a number of applications ranging from one to five. Successful results are stable with a follow-up ranging from 6 months to 3 years. CONCLUSIONS In our experience, the injection of fibrin glue has proved to be effective in filling or sealing post-operative "dead spaces" and treating minor or initial CSF leaks resulting from procedures of transsphenoidal, cranial and spinal surgery, adding another possibility in the management of many of these dreadful complications.

Abstract
INTRODUCTION Young children with significant ventricular dilatation or large intracranial fluid spaces often have a very thin cortical mantle as a result of persistently raised intracranial pressure. This rim of cortex has a tendency to fall away from the dura into the cavity during and after intracranial surgery, due to the lack of support, once the pressure in the fluid cavity has been reduced. This can lead to tearing of cortical bridging veins and the formation of post-operative subdural haematomas. METHODS We describe a simple technique that attempts to prevent this phenomenon occurring using tissue glue. Once the craniotomy has been performed and the dura has been formally opened, tissue glue is applied to the underside of the dura around the edge of the wound, prior to corticotomy. RESULTS AND CONCLUSION This results in the cortical mantle adhering to the undersurface of the dura and prevents the mantle from falling into the cavity either during the procedure or post-operatively.

Abstract
PURPOSE We reviewed the clinical outcomes resulting from various closure techniques used following endoscopic endonasal surgery for lesions in the sellar and parasellar regions. We compared our current closure technique, which uses a biological matrix of native equine collagen (TissuDura) fixed with fibrin sealant (Tisseel), with the technique we employed previously, using autologous materials, in order to assess the comparative efficacy and tolerability of both methods over the medium- to long-term. METHODS A review was conducted of all cases of endonasal endoscopic intervention carried out in our institution between 1997 and 2007. Operations performed between January 1st 1997 and December 31st 2003 involved a sellar closure technique using autologous materials, either alone or supported by fibrin sealant. From January 1st 2004, sellar reconstruction techniques involving resorbable heterologous materials were used in the closure phases. Post-operatively, clinico-endoscopic assessments took place at 15 days, 1, 3, and 6 months and yearly thereafter, supplemented by magnetic resonance imaging (MRI) scanning at 3 months and annually. RESULTS Between January 1st 1997 and December 31st 2003, 79 operations were performed in which the sellar closure technique involved the use of autologous materials. Between January 1st 2004 and January 1st 2008, 125 operations were performed in which biomaterials were used for sellar closure. The incidence of complications (fluid fistula) was 2.5% in the autologous materials closure group and 1.6% in the biomaterials closure group. The most marked difference between the two approaches was seen at 1-month follow-up, when restoration of mucociliary transport in the sphenoidal sinus and physiological functionality of the nasal mucosa and paranasal sinuses were observed to be superior in the biomaterials patient cohort. CONCLUSIONS The development of biomaterials for closure of the sellar floor offers a viable alternative to traditional techniques using autologous materials.

Abstract
The objective was to analyze the management of intraoperative CSF leaks in transsphenoidal surgeries to prevent postoperative cerebrospinal fluid (CSF) leaks. Sixty-three pituitary tumors were operated by transnasal approach. In presence of arachnoidal opening, a fat graft was placed into the sellar cavity, followed by collagen sponge layer and fibrin glue. The sphenoid sinus was also packed with fat graft and collagen sponge. An external CSF lumbar drainage was kept for 2-4 days. The variables analyzed were: intraoperative and postoperative CSF leaks, procedures, and related complications. The overall incidence of postoperative CSF leak was 1.5%. Twenty patients (31.7%) had intraoperative arachnoidal opening, 5% of whom had postoperative CSF leak. There were no reoperations because of CSF leak, and no secondary intrasellar arachnoidoceles. Mean follow-up was 3.6 years. The preventive treatment had good results and there were no complications related to the intervention strategy, encouraging us to continue performing this simple, effective, and inexpensive procedure.

Abstract
Abstract
Objective:
Transnasal endoscopic cranial base surgery is a novel minimal-access method for reaching the midline cranial base. Postoperative cerebrospinal fluid leak remains a persistent challenge. A new method for watertight closure of the anterior cranial base is presented.
Methods:
To achieve watertight closure of the anterior cranial base, autologous fascia lata was used to create a “gasket seal” around a bone buttress, followed by application of a tissue sealant such as DuraSeal (Confluent Surgical, Inc., Waltham, MA). The gasket-seal closure was used to seal the anterior cranial base in a series of 10 patients with intradural surgery for suprasellar craniopharyngiomas (n = 5), planum meningiomas (n = 3), clival chordoma (n = 1), and recurrent iatrogenic cerebrospinal fluid leak (n = 1). Lumbar drains were placed intraoperatively in five patients and remained in place for 3 days postoperatively.
Results:
After a mean follow-up period of 12 months, there were no cerebrospinal fluid leaks.
Conclusion:
The gasket-seal closure is an effective method for achieving watertight closure of the anterior cranial base after endoscopic intradural surgery.
