Optic nerve and chiasm hemangioblastomas in von Hippel-Lindau disease: report of 12 cases and review of the literature. Front Oncol 2024; 14:1334564. [PMID: 39045559 PMCID: PMC11263193 DOI: 10.3389/fonc.2024.1334564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 06/19/2024] [Indexed: 07/25/2024] Open
Abstract
Introduction Optic nerve and chiasm hemangioblastomas are rare tumors, occurring sporadically or in the context of von Hippel-Lindau (VHL) disease. They have only been portrayed in isolated case reports and small cohorts. Their natural history and therapeutic strategies are only scarcely described. To better characterize these rare tumors, we retrospectively analyzed an optic nerve and chiasm hemangioblastoma series of 12 VHL patients. By combining our own experience to a review of all known cases in literature, we intended to create treatment recommendations for optic nerve and chiasm hemangioblastomas in VHL patients. Methods We reviewed two electronic databases in the hospitals of our senior authors, searching for VHL patients with optic nerve or chiasm hemangioblastomas. Clinical data were summarized. Tumor size and growth rate were measured on contrast enhanced MRI. Comparable data were collected by literature review of all available cases in VHL patients (Pubmed, Trip, Google and Google Scholar). Results Of 269 VHL patients, 12 had optic nerve or chiasm hemangioblastomas. In 10 of 12 patients, tumors were diagnosed upon annual ophthalmoscopic/MRI screening. Of 8 patients who were asymptomatic at diagnosis, 7 showed absent or very slow annual progression, without developing significant vision impairment. One patient developed moderate vision impairment. Two symptomatic patients suffered from rapid tumor growth and progressive vision impairment. Both underwent late-stage surgery, resulting in incomplete resection and progressive vision impairment. One patient presented with acute vision field loss. A watchful-waiting approach was adopted because the hemangioblastoma was ineligible for vision-sparing surgery. One patient developed progressive vision impairment after watchful waiting. In the literature we found 45 patient cases with 48 hemangioblastomas. Discussion When optic nerve and chiasm hemangioblastomas are diagnosed, we suggest annual MRI follow-up as long as patients do not develop vision impairment. If tumors grow fast, threaten the contralateral eye, or if patients develop progressive vision deficiency; surgical resection must be considered because neurological impairment is irreversible, and resection of large tumors carries a higher risk of further visual decline.

Abstract
BACKGROUND AND OBJECTIVES There is considerable controversy as to which of the 2 operating modalities (microsurgical or endoscopic transnasal surgery) currently used to resect pituitary adenomas (PAs) is the safest and most effective intervention. We compared rates of clinical outcomes of patients with PAs who underwent resection by either microsurgical or endoscopic transnasal surgery. METHODS To independently assess the outcomes of each modality type, we sought to isolate endoscopic and microscopic PA surgeries with a 1:1 tight-caliper (0.01) propensity score-matched analysis using a multicenter, neurosurgery-specific database. Surgeries were performed between 2017 and 2020, with data collected retrospectively from 12 international institutions on 4 continents. Matching was based on age, previous neurological deficit, American Society of Anesthesiologists (ASA) score, tumor functionality, tumor size, and Knosp score. Univariate and multivariate analyses were performed. RESULTS Among a pool of 2826 patients, propensity score matching resulted in 600 patients from 9 surgery centers being analyzed. Multivariate analysis showed that microscopic surgery had a 1.91 odds ratio (OR) ( P = .03) of gross total resection (GTR) and shorter operative duration ( P < .01). However, microscopic surgery also had a 7.82 OR ( P < .01) for intensive care unit stay, 2.08 OR ( P < .01) for intraoperative cerebrospinal fluid (CSF) leak, 2.47 OR ( P = .02) for postoperative syndrome of inappropriate antidiuretic hormone secretion (SIADH), and was an independent predictor for longer postoperative stay (β = 2.01, P < .01). Overall, no differences in postoperative complications or 3- to 6-month outcomes were seen by surgical approach. CONCLUSION Our international, multicenter matched analysis suggests microscopic approaches for pituitary tumor resection may offer better GTR rates, albeit with increased intensive care unit stay, CSF leak, SIADH, and hospital utilization. Better prospective studies can further validate these findings as matching patients for outcome analysis remains challenging. These results may provide insight into surgical benchmarks at different centers, offer room for further registry studies, and identify best practices.

Endoscopic Endonasal Transplanum-Transtuberculum Approach for Pituitary Adenomas/PitNET: 25 Years of Experience. Brain Sci 2023; 13:1121. [PMID: 37509051 PMCID: PMC10377303 DOI: 10.3390/brainsci13071121] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 07/16/2023] [Accepted: 07/20/2023] [Indexed: 07/30/2023] Open
Abstract
The role of the endoscopic transplanum-transtuberculum approach (ETTA) in the treatment of pituitary adenomas/PitNETs (PAs) is sparsely analyzed in the literature, and its use is still debated in the current practice. The aim of this study was to report our experience with this approach. Our institutional registry was retrospectively reviewed, and patients who underwent ETTA for a PA from 1998 to 2022 were included. Fifty-seven cases were enrolled over a time span of 25 years, corresponding to 2.4% of our entire PA caseload. Radical resection was achieved in 57.9% of cases, with re-do surgery (p = 0.033) and vessel encasement/engulfment (p < 0.001) as predictors of partial resection. CSF leak incidence stood at 8.8%, with higher BMI (p = 0.038) as its only significant predictor. Partial or full improvement of the visual field deficits was achieved in 73.5% of cases. No surgical mortality was observed. According to our results, ETTA for the treatment of PAs is characterized by a satisfactory surgical outcome but with greater morbidity than the conventional endoscopic approach. Therefore, it should be reserved for the few selected cases otherwise unsuitable for the endoscopic trans-sphenoidal route, representing a valid alternative and an effective complementary route for the transcranial approach for these challenging PAs.

Endoscopic endonasal surgical anatomy through the prechiasmatic sulcus: the key window to suprachiasmatic and infrachiasmatic corridors. Acta Neurochir (Wien) 2022; 164:1929-1938. [PMID: 35410400 DOI: 10.1007/s00701-022-05196-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 03/26/2022] [Indexed: 12/20/2022]
Abstract
BACKGROUND Classically, the transtuberculum and transplanum approaches have been utilized to reach the suprachiasmatic and infrachiasmatic corridors. The aim of this study was to provide a better understanding of the key endoscopic endonasal anatomy of the suprachiasmatic and infrachiasmatic corridors provided through selective removal of the prechiasmatic sulcus (SRPS). METHOD A SRPS was performed in 16 sides of 8 alcohol-fixed head specimens. Twenty anatomical measurements were collected on the suprachiasmatic and infrachiasmatic corridors. The transplanum and transtuberculum approaches were also performed. RESULTS In the suprachiasmatic corridor, the SRPS exposed the anterior communicating artery (AComm) and the post-communicating segment of the anterior cerebral arteries in all the cases, while the pre-communicating segment of the anterior cerebral arteries, recurrent arteries of Heubner, and fronto-orbital arteries were visualized in 75% (12/16), 31% (5/16), and 69% (11/16) of cases, respectively. In the infrachiasmatic corridor, the ophthalmic segment of the internal carotid artery and superior hypophyseal arteries were always visible through the SRPS. The mean width and height of the prechiasmatic sulcus were 13.2 mm and 9.6 mm, respectively. The mean distances from the midpoint of the AComm to the anterior margin of the optic chiasm (OCh) was 5.3 mm. The mean width of the infrachiasmatic corridor was 12.3 mm at the level of the proximal margin of the ophthalmic segment of the internal carotid artery. The mean distances from the posterior superior limit of the pituitary stalk to the basilar tip and oculomotor nerve were 9.7 mm and 12.3 mm, respectively. CONCLUSIONS The SRPS provides access to the main neurovascular and cisternal surgical landmarks of the suprachiasmatic and infrachiasmatic corridors. This anatomical area constitutes the key part of the approach to the suprasellar area. To afford adequate surgical maneuverability, the transplanum or transtuberculum approaches are usually a necessary extension.

Neuroimaging Features of Optic Nerve Hemangioblastoma Identified by Conventional and Advanced Magnetic Resonance Techniques: A Case Report and Literature Review. Front Oncol 2021; 11:763696.

Abstract
Optic nerve hemangioblastoma is a very rare benign tumor with only 39 reported cases by now. It appears to be hyperintense on T2-weighted images with a significant enhancement on contrast scans, which are similar to glioma and meningioma. Due to the lack of specificity in MRI manifestations, optic nerve hemangioblastoma is often misdiagnosed. To provide new insights into differential diagnosis of optic nerve hemangioblastoma, we report for the first time an optic nerve hemangioblastoma case employing advanced magnetic resonance techniques including diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) maps, and magnetic resonance angiography (MRA). In addition, we have collected all reported optic nerve hemangioblastoma cases and reviewed their neuroimaging findings by MRI and angiography. Our results show that solid-type tumor is the dominant form of optic nerve hemangioblastoma and extensive edema is widely observed. These findings are surprisingly contrary to manifestations of cerebellar hemangioblastoma. Besides the structural features, quantitative indexes including ADC and relative cerebral blood volume (rCBV) ratio, which are significantly elevated in cerebellar hemangioblastoma, may also shed a light on the preoperative diagnosis of hemangioblastoma of optic nerve. Finally, we discuss the critical neuroimaging features in the differential diagnosis between optic nerve hemangioblastoma from optic pathway glioma and optic nerve sheath meningioma.

Abstract
Purpose
Our case report presents the first case of suprasellar hemangioblastoma diagnosed preoperatively with dynamic computed tomography angiography (four-dimensional [4D] CTA) in a patient without Von Hippel-Lindau (VHL) disease. We illustrate the imaging characteristics of these exceedingly rare tumors and discuss the role of 4D CTA in confirming this diagnosis and guiding surgical management. Finally, we present a literature review of imaging findings, differential diagnosis, management, and prognosis.
Case
A 39-year-old woman known for diabetes mellitus type II and dyslipidemia presented with headache, bitemporal hemianopsia, and mild hyperprolactinemia. Initial diagnosis of suprasellar meningioma separate from pituitary gland was revised to definitive diagnosis of suprasellar hemangioblastoma after 4D CTA.
Conclusion
Suprasellar hemangioblastomas are extremely rare, often associated to VHL disease. They present as enhancing as suprasellar mass with prominent intra- and peritumoral vascular flow-voids on magnetic resonance imaging. 4D CTA confirms their vascular nature, demonstrates characteristic rapid shunting with feeding arteries, and enlarged draining veins, and is important in guiding surgical management.

Abstract
BACKGROUND Retrobulbar hemangioblastomas involving the optic apparatus in patients with von Hippel-Lindau disease (VHL) are rare, with only 25 reported cases in the literature. OBJECTIVE To analyze the natural history of retrobulbar hemangioblastomas in a large cohort of VHL patients in order to define presentation, progression, and management. METHODS Clinical history and imaging of 250 patients with VHL in an ongoing natural history trial and 1774 patients in a neurosurgical protocol were reviewed. The clinical course, magnetic resonance images, treatment, and outcomes were reviewed for all included patients. RESULTS A total of 18 patients with retrobulbar hemangioblastoma on surveillance magnetic resonance imaging met the inclusion criteria for this study. Of the 17 for whom clinical information was available, 10 patients presented with symptoms related to the hemangioblastoma, and 7 were asymptomatic. The mean tumor volume was larger for symptomatic (810.6 ± 545.5 mm3) compared to asymptomatic patients (307.6 ± 245.5 mm3; P < .05). A total of 5 of the symptomatic patients were treated surgically and all experienced improvement in their symptoms. All 3 symptomatic patients that did not undergo intervention had continued symptom progression. Long-term serial imaging on asymptomatic patients showed that these tumors can remain radiographically stable and asymptomatic for extended periods of time (101.43 ± 71 mo). CONCLUSION This study suggests that retrobulbar hemangioblastomas may remain stable and clinically asymptomatic for long durations. Recent growth and larger tumor volume were associated with symptom occurrence. Surgical treatment of symptomatic retrobulbar hemangioblastomas can be safe and may reverse the associated symptoms.

Abstract
Germ cell tumors are rare malignant tumors frequently located in the suprasellar region. Definitive treatment is chemotherapy and radiation. However, in some circumstances, surgery is indicated for biopsy or resection. There are limited reports of the role of the endonasal endoscopic approach (EEA) in the management of this tumor. We present two cases in which EEA was utilized for successful management of germ cell tumor. The most challenging aspect of germ cell tumor management for the treating physician is knowing the proper indications for surgery. In this paper, we highlight two specific instances, namely diagnosis and tumor refractory to chemoradiation. Given the suprasellar location, EEA is an ideal approach.

Abstract
Surgery of suprasellar meningiomas is a challenge and associated with a high risk of injury to the vascular-neural structures lying along the approach and surrounding the tumor. Currently, many foreign clinics and our Center have introduced a technique for resection of suprasellar meningiomas through the anterior extended transsphenoidal endoscopic endonasal approach. OBJECTIVE The study objective was to evaluate the role of extended transsphenoidal endoscopic endonasal approaches in surgery of suprasellar meningiomas. MATERIAL AND METHODS The present study is a retrospective analysis of surgical treatment outcomes in 45 patients (11 males and 34 females aged 23 to 70 years (median, 50 years) with suprasellar meningiomas who underwent surgery for skull base tumors using the anterior extended transsphenoidal endoscopic endonasal approach in the Surgery Department of the Burdenko Neurosurgical Institute in the period from 2009 to 2017. In all cases, surgery was the primary method of treatment. RESULTS Total tumor resection (the tumor was resected completely together with an infiltrated DM - Simpson 1) was achieved in 77.8% (35/45) of cases; subtotal resection (more than 80% of the tumor was removed) was in 17.8% (8/45) of cases; in 4.4% (2/45) of cases, resection was partial (less than 80% of the tumor was resected). Worsening or development of visual impairments immediately after surgery occurred in 13 (28%) of 45 patients. In 3 of them, vision was completely recovered on conservative treatment by the time of hospital discharge. In 4 patients, vision partially improved by the time of discharge. In 6 patients, vision was not recovered by discharge (in 2 of them, vision partially improved during follow-up). Therefore, by the time of hospital discharge, deterioration in vision occurred in 10 (22%) of 45 patients. In 7 (21.2%) out of 33 patients who had visual impairments before surgery, there was an improvement in vision in the postoperative period. CONCLUSION Analyzing the findings and generalizing our experience, we may say that, in surgery of suprasellar meningiomas, the anterior extended transsphenoidal endoscopic endonasal approach should be used for relatively small (up to 3 cm), medially located symmetrical tumors that do not involve large vessels. The efficacy of this technique for tumors extending into the optic nerve canals requires additional analysis in a larger series of cases.

Abstract
OBJECTIVE The aim of this study was to analyze the outcomes of transsphenoidal surgery (TSS) in a single-center clinical series of pediatric craniopharyngioma patients treated with gross-total resection (GTR). METHODS The authors retrospectively reviewed the surgical outcomes for 65 consecutive patients with childhood craniopharyngiomas (28 girls and 37 boys, mean age 9.6 years) treated with TSS (45 primary and 20 repeat surgeries) between 1990 and 2015. Tumors were classified as subdiaphragmatic or supradiaphragmatic. Demographic and clinical characteristics, including extent of resection, complications, incidence of recurrence, pre- and postoperative visual disturbance, pituitary function, and incidence of diabetes insipidus (DI), as well as new-onset obesity, were analyzed and compared between the primary surgery and repeat surgery groups. RESULTS Of the 45 patients in the primary surgery group, 26 (58%) had subdiaphragmatic tumors and 19 had supradiaphragmatic tumors. Of the 20 patients in the repeat surgery group, 9 (45%) had subdiaphragmatic tumors and 11 had supradiaphragmatic tumors. The only statistically significant difference between the 2 surgical groups was in tumor size; tumors were larger (mean maximum diameter 30 mm) in the primary surgery group than in the repeat surgery group (25 mm) (p = 0.008). GTR was accomplished in 59 (91%) of the 65 cases; the GTR rate was higher in the primary surgery group than in the repeat surgery group (98% vs 75%, p = 0.009). Among the patients who underwent GTR, 12% experienced tumor recurrence, with a median follow-up of 7.8 years, and recurrence tended to occur less frequently in primary than in repeat surgery patients (7% vs 27%, p = 0.06). Of the 45 primary surgery patients, 80% had deteriorated pituitary function and 83% developed DI, whereas 100% of the repeat surgery patients developed these conditions. Among patients with preoperative visual disturbance, vision improved in 62% but worsened in 11%. Visual improvement was more frequent in primary than in repeat surgery patients (71% vs 47%, p < 0.001), whereas visual deterioration was less frequent following primary surgery than repeat surgery (4% vs 24%, p = 0.04). Among the 57 patients without preoperative obesity, new-onset postoperative obesity was found in 9% of primary surgery patients and 21% of repeat surgery patients (p = 0.34) despite aggressive resection, suggesting that hypothalamic dysfunction was rarely associated with GTR by TSS in this series. However, obesity was found in 25% of the repeat surgery patients preoperatively due to prior transcranial surgery. Although there were no perioperative deaths, there were complications in 12 cases (18%) (6 cases of CSF leaks, 3 cases of meningitis, 2 cases of transient memory disturbance, and 1 case of hydrocephalus). Postoperative CSF leakage appeared to be more common in repeat than in primary surgery patients (20% vs 4.4%, p = 0.2). CONCLUSIONS The results of TSS for pediatric craniopharyngioma in this case series suggest that GTR should be the goal for the first surgical attempt. GTR should be achievable without serious complications, although most patients require postoperative hormonal replacement. When GTR is not possible or tumor recurrence occurs after GTR, radiosurgery is recommended to prevent tumor regrowth or progression.

Abstract
BACKGROUND Hemangioblastomas usually occur in the cerebellum and are often a component of von Hippel-Lindau disease. Edema-like changes along the optic tract are commonly observed in association with tumors in the sellar and suprasellar regions, such as craniopharyngiomas and pituitary adenomas. Here, we describe a case of sporadic suprasellar hemangioblastoma with edema-like changes along the optic tract that completely resolved after surgery. CASE DESCRIPTION The patient was a 28-year-old woman with failing vision and a bitemporal hemianopia. Magnetic resonance imaging revealed a tumor accompanied by a 10-mm cyst. Fluid-attenuated inversion recovery axial magnetic resonance imaging revealed a hyperintense region along the optic tract. Other regions of the central nervous system were normal. Endoscopic transsphenoidal surgery was performed, and the histopathologic findings confirmed hemangioblastoma. Six months after surgery, the edema-like change along the optic tract had disappeared. The patient is doing well without pituitary insufficiency, pituitary hormone medications, or signs of tumor recurrence. In addition, the genetic test was negative for von Hippel-Lindau mutations. CONCLUSIONS When examining a patient with suprasellar tumor, clinicians must consider the possibility of hemangioblastoma. Adequate treatment can improve the edematous change and visual disturbance.

Abstract
Hemangioblastomas (HBLs) are challenging vascular tumours with rare suprasellar location Surgery is recommended in patients with visual impairment, endocrine disorders or hydrocephalus. Surgical removal of pituitary stalk HBLs is challenging due to their location and high vascularity. Our narrative review was guided by the question: "what is the more suitable surgical approach to excise a suprasellar HBL?". Pertinent English literature was scrutinized from database inception to October 2016. Eighteen articles matched our selection criteria. Among the surgically treated patients, 4 were treated through a trans-sphenoidal (TS) approach, 13 through a transcranial approach (2 of them after TS failure). Five other cases were treated with radiotherapy (adjuvant in 3 cases) and 9 patients were managed with simple observation and/or medical treatment. We add a case of complete suprasellar HBL resection through an orbito-zygomatic (OZ) craniotomy with extradural anterior clinoidectomy (EAC). To achieve satisfactory oncologic results with acceptable morbidity for symptomatic suprasellar HBLs, complete tumour removal with pituitary stalk sparing should be attempted through an OZ craniotomy with EAC that provides adequate exposure of the tumour, its vascular supply and the adjacent neural structures.

Abstract
Optic nerve haemangioblastomas remain exceedingly rare extrinsic tumours of the optic nerve, often associated with von Hippel-Lindau disease. The authors report a 25-year-old female with a slowly progressive unilateral optic nerve lesion, causing reduced vision and bilateral optic tract oedema. A diagnosis of optic nerve haemangioblastoma with piloid gliosis was made histologically after surgical resection. This is the first reported case of such dual pathology occurring in the optic nerve. The patient has been monitored without further adjuvant treatment, and has not had a recurrence to date, at 6 years of follow-up.

Abstract
We evaluated the features of clinically nonfunctioning giant pituitary adenomas (NFGPAs) causing hydrocephalus to highlight the timing of hydrocephalus management and surgical approaches. A total of 24 patients with NFGPAs and hydrocephalus were included. Eighteen patients underwent endoscopic transsphenoidal surgery. Ten patients received pterional surgery, including 6 patients as first treatment and 4 cases with recurrence after transsphenoidal approach. Gross total resection was achieved in 10 patients, including 6 cases (6/18, 33.3%) with endoscopic transsphenoidal surgery and 4 cases (4/10, 40%) with pterional surgery. All patients were divided into preoperative EVD group and non-preopoerative EVD group. The proportion of patients receiving postoperative EVD or shunt was significantly higher in non-preoperative EVD group than that in preoperative EVD group (9/15 vs. 1/9, P = 0.033). Visual impairment score (VIS) was evaluated for each patient. We detected significant vision improvement according to the preoperative and postoperative VIS (median, interquartile range: 62, 48.25–77 vs. 36.5, 0–50.75, P < 0.001). Conclusively, for patients with NFGPAs and hydrocephalus, preoperative EVD might reduce the need for a second shunt or EVD. Surgical approach should be decided based on the clinicoradiological features and surgeons’ experience for individualized treatment, and endoscopic transsphenoidal resection of pituitary adenomas was suggested for most NFGPAs.

Abstract
BACKGROUND Craniopharyngiomas have traditionally been treated via open transcranial approaches. More recently, endoscopic transsphenoidal approaches have been increasingly used; however, few case series exist in the pediatric population. METHODS A retrospective review of patients (aged <18 years) undergoing endoscopic transsphenoidal resection of craniopharyngiomas between 1995 and 2016 was performed. Preoperative data included presenting symptoms, tumor size, location, and components. Postoperative outcomes included symptom resolution, visual outcomes, endocrine outcomes, disease recurrence, and major complications. RESULTS Sixteen pediatric patients with mean age of 11.0 years (range, 5-15 years) were included. The median follow-up time was 56.2 months. Mean maximal tumor diameter was 3.98 cm. Most of the tumors had suprasellar (93.8%) and intrasellar (68.8%) components. The gross total resection rate was 93.8%. The most common presenting symptoms were vision changes (81.3%) and increased intracranial pressure (56.3%). Most patients (66.7%) had their presenting symptoms resolved by their first postoperative visit. Vision improved or remained normal in 69.2% of patients. Postoperatively, new incidence of panhypopituitarism or diabetes insipidus developed in 63.6% and 46.7% of patients, respectively. New hypothalamic obesity developed in 28.6% of patients. The postoperative cerebrospinal fluid leak rate was 18.8%. One patient died of intraventricular hemorrhage postoperatively. The major complication rate was 12.5%. Disease recurrence occurred in 1 patient with gross total resection (6.3%). CONCLUSIONS Endoscopic transsphenoidal resection for craniopharyngiomas can achieve high rates of total resection with low rates of disease recurrence in larger tumors than previously described. However, hypothalamic-pituitary dysfunction and cerebrospinal fluid leak remain significant postoperative morbidities.

Abstract
Craniopharyngioma is a rare clinical entity that poses a significant management challenge given their location and propensity to recur. As part of a minimally disruptive treatment paradigm, the expanded endonasal approach has the potential to improve rates of resection, improve postoperative visual recovery, and minimize surgical morbidity. This article updates the otolaryngologic community on the basic principles and techniques regarding the incorporation of the endoscopic, endonasal approach in the management paradigm of craniopharyngioma.

Abstract
A better understanding of surgical anatomy, marked improvement in illumination devices, provision of improved hemostatic agents, greater availability of more precise surgical instruments, and better modalities for skull base reconstruction have led to an inevitable evolution of skull base neurosurgery. For the past few decades, many skull base neurosurgeons have worked relentlessly to improve the surgical approach and trajectory for the expansion of operative corridor. With the advent of newer techniques and their rapid adaptation, it is foundational, especially for young neurosurgeons, to understand the basics and nuances of modifications of traditional neurosurgical approaches. The goal of this topic review is to discuss the evolution of, concepts in, and technical nuances regarding the operative corridor expansion in the field of skull base surgery for intracranial meningioma as they pertain to achieving optimal functional outcome.

Abstract
Objective: Surgical treatment of retrochiasmatic craniopharyngioma still remains a challenge. While complete removal of the tumor with preservation of the vital neurovascular structures is often the goal of the treatment, there is no optimal surgical approach available to achieve this goal. Transcranial and transsphenoidal microsurgical approaches, commonly used in the past, have considerable technical limitations. The extended endonasal endoscopic surgical route, obtained by removal of tuberculum sellae and planum sphenoidale, offers direct midline access to the retrochiasmatic space and provides excellent visualization of the undersurface of the optic chiasm. In this report, we describe the technical details of the extended endoscopic approach, and review our results using this approach in the surgical management of retrochiasmatic craniopharyngiomas. Methods: Fifteen children, including 9 girls and 6 boys, aged 8 to 15 years underwent surgery using extended endoscopic transsphenoidal approach between 2008 and 2014. Nine patients had a surgical procedure done previously and presented with recurrence of symptoms and regrowth of their residual tumors. Results: A gross total or near total excision was achieved in 10 (66.7%) patients, subtotal resection in 4 (26.7%), and partial removal in 1 (6.7%) patient. Postoperatively, headache improved in 93.3%, vision recovered in 77.3%, and the hormonal levels stabilised in 66.6%. Three patients (20%) developed postoperative CSF leaks which were managed conservatively. Three (20%) patients with diabetes insipidus and 2 (13.3%) with panhypopituitarism required long-term hormonal replacement therapy. Conclusions: Our early experience suggests that the extended endonasal endoscopic approach is a reasonable option for removal of the retrochiasmal craniopharyngiomas. Compared to other surgical approaches, it provides better opportunities for greater tumor removal and visual improvement without any increase in risks.

Abstract
Hemangioblastoma (HBL) in the pituitary stalk is extremely rare. Only 16 such cases have been reported in the past and 5 cases have been treated with surgical procedure. Here, we report surgical case of HBL in the pituitary stalk diagnosed in a 34-year-old woman. The patient underwent a gross-total resection via the modified lateral supra-orbital approach. No recurrence was observed in two years after surgery. To our knowledge, this is the 17th case of HBL in the pituitary stalk and the 6th surgical case. If the tumor is symptomatic and the volume is over 5 cubic centimeters as in our case, we recommend that the surgical resection of the HBL in the pituitary stalk is a more safe and reasonable than radiotherapy.

Abstract
Background Endoscopic endonasal skull base reconstructions have been associated with postoperative cerebrospinal fluid (CSF) leaks. Objective A repair protocol for endoscopic endonasal skull base reconstruction is presented with the objective of decreasing the overall leak rate. Methods A total of 180 endoscopic endonasal skull base reconstructions were reviewed. Reconstructions were classified I to IV according to the reconstruction method, determined by severity of intraoperatively encountered CSF leaks for types I to III, and planned preoperatively for type IVs, which required nasoseptal flap. Results A total of 11 patients(6%) had postoperative leaks: 0 in type I (0%), 2 in type II (5%), 7 in type III (18%), and 2 (4%) in type IV reconstruction. Type III leak rate was higher than all other reconstructions. Total 31 intraoperative and 16 postoperative lumbar drains were placed. More patients had lumbar drains placed postoperatively for type III and intraoperatively for type IV than all other groups. There were significant overall differences in postoperative CSF leaks and lumbar drain placement between the four reconstruction types. No patient with type III reconstruction and intraoperative lumbar drain had postoperative CSF leak. Conclusions A repair protocol for endoscopic endonasal reconstructions determined by intraoperative CSF leak and preoperative planning minimizes unnecessary repair materials and additional morbidity. Our experience leads to a routine prophylactic lumbar drain placement in all type III leak and reconstructions. We also favor the type III reconstruction for minor intraoperative leaks, and a more generous use of type IV reconstructions in expectation of significant intraoperative CSF leak. The option of rescue flap technique in type III leaks should be strongly considered.

Abstract
OBJECTIVE Craniopharyngiomas and similar midline suprasellar tumors have traditionally been resected via transcranial approaches. More recently, expanded endoscopic endonasal transsphenoidal approaches have gained interest. Surgeons have advocated for both approaches, and at present there is no consensus whether one approach is superior to the other. The authors therefore compared surgical outcomes between craniotomy and endoscopic endonasal transsphenoidal surgery (EETS) for suprasellar tumors treated at their institution. METHODS A retrospective review of patients undergoing resection of suprasellar lesions at Cedars-Sinai Medical Center between 2000 and 2013 was performed. Patients harboring suspected craniopharyngioma were selected for extensive review. Other pathologies or predominantly intrasellar masses were excluded. Cases were separated into 2 groups, based on the surgical approach taken. One group underwent EETS and the other cohort underwent craniotomy. Patient demographic data, presenting symptoms, and previous therapies were tabulated. Preoperative and postoperative tumor volume was calculated for each case based on MRI. Student t-test and the chi-square test were used to evaluate differences in patient demographics, tumor characteristics, and outcomes between the 2 cohorts. To assess for selection bias, 3 neurosurgeons who did not perform the surgeries reviewed the preoperative imaging studies and clinical data for each patient in blinded fashion and indicated his/her preferred approach. These data were subject to concordance analysis using Cohen's kappa test to determine if factors other than surgeon preference influenced the choice of surgical approach. RESULTS Complete data were available for 53 surgeries; 19 cases were treated via EETS, and 34 were treated via craniotomy. Patient demographic data, preoperative symptoms, and tumor characteristics were similar between the 2 cohorts, except that fewer operations for recurrent tumor were observed in the craniotomy cohort compared with EETS (17.6% vs 42.1%, p = 0.05). The extent of resection was similar between the 2 groups (85.6% EETS vs 90.7% craniotomy, p = 0.77). An increased rate of cranial nerve injury was noted in the craniotomy group (0% EETS vs 23.5% craniotomy, p = 0.04). Postoperative CSF leak rate was higher in the EETS group (26.3% EETS vs 0% craniotomy, p = 0.004). The progression-free survival curves (log-rank p = 0.99) and recurrence rates (21.1% EETS vs 23.5% craniotomy, p = 1.00) were similar between the 2 groups. Concordance analysis of cases reviewed by 3 neurosurgeons indicated that individual surgeon preference was the only factor that determined surgical approach (kappa coefficient -0.039, p = 0.762) CONCLUSIONS: Surgical outcomes were similar for tumors resected via craniotomy or EETS, except that more CSF leaks occurred in the EETS cohort, whereas more neurological injuries occurred in the craniotomy cohort. Surgical approach appears to mostly reflect surgeon preference rather than specific tumor characteristics. These data support the view that EETS is a viable alternative to craniotomy, providing a similar extent of resection with less neurological injury.

Abstract
BACKGROUND The past two decades have been the setting for remarkable advancement in endonasal endoscopic neurosurgery. Refinements in camera definition, surgical instrumentation, navigation, and surgical technique, including the dual surgeon team, have facilitated purely endonasal endoscopic approaches to the majority of the midline skull base that were previously difficult to access through the transsphenoidal microscopic approach. METHODS This review article looks at many of the articles from 2011 to 2014 citing endonasal endoscopic surgery with regard to approaches and reconstructive techniques, pathologies treated and outcomes, and new technologies under consideration. RESULTS Refinements in approach and closure techniques have reduced the risk of cerebrospinal fluid leak and infection. This has allowed surgeons to more aggressively treat a variety of pathologies. Four main pathologies with outcomes after treatment were identified for discussion: pituitary adenomas, craniopharyngiomas, anterior skull base meningiomas, and chordomas. Within all four of these tumor types, articles have demonstrated the efficacy, and in certain cases, the advantages over more traditional microscope-based techniques, of the endonasal endoscopic technique. CONCLUSIONS The endonasal endoscopic approach is a necessary tool in the modern skull base surgeon's armamentarium. Its efficacy for treatment of a wide variety of skull base pathologies has been repeatedly demonstrated. In the experienced surgeon's hands, this technique may offer the advantage of greater tumor removal with reduced overall complications over traditional craniotomies for select tumor pathologies centered near the midline skull base.

Abstract
INTRODUCTION A certain interest for the extended endoscopic endonasal approach for the management of sellar-suprasellar lesions extending inside the third ventricle has been growing in recent years. The aim of this anatomical study was to evaluate the possibilities in terms of exposure and access to the different areas of the third ventricle, with the endoscopic endonasal technique, as compared with the microscopic or endoscopic view provided via different transcranial approaches. The advantages and limitations of both surgical pathways were analyzed. MATERIALS AND METHODS Ten human cadaver heads were dissected. In order to standardize the comparison between the endonasal and the transcranial routes, the third ventricle cavity has been divided into four areas by means of two ideal planes, one passing through the optic chiasm and the interthalamic commissure and one passing through the posterior edge of the foramen of Monro and the interthalamic commissure. Accordingly, two anterior (infundibular and foraminal) and two posterior (mesencephalic and tectal) areas have been defined. RESULTS The endoscopic endonasal approach allows for exploration and surgical maneuverability, especially in the anterior areas of the third ventricle. In the infundibular and foraminal areas the surgical maneuverability seems to be better as compared with that obtained inside the mesencephalic region, while via the endonasal route the tectal area could not be reached. In particular, the infundibular area can be explored either passing through the lamina terminalis or via the tuber cinereum; this latter trajectory enables visualization of the foramina of Monro and the floor of the third ventricle up to the pineal recess. CONCLUSION This anatomical study shows that the lamina terminalis and, above all, the tuber cinereum represent two safe entry points defining possible surgical corridors to be considered for the extended endoscopic endonasal approach to the third ventricle.

Abstract
Endoscopic endonasal surgery has been established as the safest approach to pituitary tumors, yet its role in other common skull base lesions has not been established. To answer this question, we carried out a systematic review of reported series of open and endoscopic endonasal approaches to four major skull base tumors: olfactory groove meningiomas (OGM), tuberculum sellae meningiomas (TSM), craniopharyngiomas (CRA), and clival chordomas (CHO). Data from 162 studies containing 5,701 patients were combined and compared for differences in perioperative mortality, gross total resection (GTR), cerebrospinal fluid (CSF) leak, neurological morbidity, post-operative visual function, post-operative anosmia, post-operative diabetes insipidus (DI), and post-operative obesity/hyperphagia. Weighted average rates for each outcome were calculated using relative study size. Our findings indicate similar rates of GTR and perioperative mortality between open and endoscopic approaches for all tumor types. CSF leak was increased after endoscopic surgery. Visual function symptoms were more likely to improve after endoscopic surgery for TSM, CRA, and CHO. Post-operative DI and obesity/hyperphagia were significantly increased after open resection in CRA. Recurrence rates per 1,000 patient-years of follow-up were higher in endoscopy for OGM, TSM, and CHO. Trends for open and endoscopic surgery suggested modest improvement in all outcomes over time. Our observations suggest that endonasal endoscopy is a safe alternative to craniotomy and may be preferred for certain tumor types. However, endoscopic surgery is associated with higher rates of CSF leak, and possibly increased recurrence rates. Prospective study with long-term follow-up is required to verify these preliminary observations.

Abstract
AbstractCraniopharyngiomas are rare, highly complex tumors with bimodal incidence in the pediatric and adult age groups. In our opinion, depending on the means possible, total microscopic ablation offers the best chance of healing, or at least prolongs the time interval of recurrences.Objective : The purpose of this paper is to add our surgical experience to in the last 11 years, in the context of the large debate from literature regarding the best therapeutically option concerning craniopharyngioma treatments.Materials and Methods : We performed a retrospective analysis of 42 consecutive patients with craniopharyngioma who underwent surgical resection by one surgeon at the Neurosurgical Department of Cluj-Napoca County Emergency Hospital between January 2002 and December 2012. We perform a systematic review of the published review on goals and techniques associated with selected surgical strategies for the treatment of CPH.Results : During this period a total of 42 patients with craniopharyngioma were treated in our institution by a single neurosurgeon, representing 12% from all cases of sellar and parasellar tumors respectively operated in last 11 years. There is a significant male preponderance. Nine patients were less than 18 years of age at admission. The patient age distribution showed a peak incidence between 10 and 15 years and another between 45 and 50 years. Considering the pediatric and adult populations together, the most common presenting symptom was visual disturbances with 60% of patients presenting in this manner, followed by severe headache in more than 50% of cases. Obstructive hydrocephalus occurred in 31% of cases. Calcifications were seen in 45% of cases, more frequently in children. All our cases underwent surgery by transcranial approach; extended frontotemporal, as the first choice, in 57% of cases. Gross total removal was achieved in over half of cases and near total resection was achieved in 40% of cases. The most frequent postoperative complications: diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion. No visual impairment was observed after surgery in the patients with normal visions at presentation. Only 3 of cases primarily operated by us recurred, in an interval of one to five years. The mortality rate in our cases treated by transcranial surgery was 2% in primary cases and 7% in cases of tumor recurrence.Conclusions : Radical surgery offers the best chance for cure. Radical surgery is also associated with a higher risk of postoperative morbidity, being the reason for why many neurosurgeons recommend a subtotal resection followed by radiotherapy. In our opinion radical surgery is possible in large majority of the cases, fronto-temporal approach offering the most appropriate way to reach this objective. Every case must be judged with maximal attention based on preoperative neuroimagistic data but decisively, on intraoperative findings.

Abstract
Transsphenoidal approach is considered the treatment of choice for pituitary adenoma removal. Suprasellar extension is regarded a drawback for complete removal of these tumors through this approach. Evaluate the correlation between the preoperative radiologic craniocaudal extension on MRI of pituitary adenomas and the extent of tumor removal. A retrospective study. Tertiary care hospital. 560 patients underwent transsphenoidal removal of pituitary adenomas. The degree of removal of pituitary tumor in the follow-up imaging of the patients was correlated with the preoperative extension in mid-Coronal T1 W Gd. Tumors with suprasellar extension can be classified into: Type I tumors with extension confined to the sellar boundaries, resulted in complete removal in all cases (100%), type II tumors with suprasellar extension reaching the floor of the 3rd ventricle, resulted in complete removal in 70.2% of the cases, type III tumors with suprasellar extension above the 3rd ventricle, had only 13.5% of complete removal. Integration of radiologic findings into a scheme for the preoperative determination of possibility of total removal of the tumor through transsphenoidal approach, can give better correlation to the surgical outcome of pituitary tumors.

Abstract
Pituitary surgery is a continuously evolving specialty of neurosurgery that requires precise anatomical knowledge, technical skills, and an integrated appreciation of pituitary pathophysiology. It involves close cooperation between different specialists, i.e., the endocrinologist, neurosurgeon, neuroradiologist, pathologist, ophthalmologist, and others. It is currently possible to manage many of the different pituitary syndromes with more than one option, including medical, surgical, and radiotherapeutic options, either alone or in various combinations. In recent decades, the transsphenoidal midline route became the standard approach to the pituitary area, this being a less traumatic direct route to the sella, avoiding brain retraction and providing excellent visualization, with a lower morbidity and mortality rate as compared to transcranial procedures. Most pituitary adenomas can be managed and removed through a standard transsphenoidal approach, either microscopic or endoscopic. More recently, the introduction of the endoscope in the extended endoscopic endonasal approach has become more widespread. Here we report current indications and give a step-by-step account of the surgical techniques used in pituitary surgery, focusing on the "dangerous keypoints". We also describe possible complications of each kind of procedure.

Abstract
Hemangioblastoma in the suprasellar region is rare. We present a case of a suprasellar hemangioblastoma that underwent surgical resection using an extended endoscopic transsphenoidal approach. A 64-year-old female patient presented with headache and decreased visual acuity for the last four years, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a 2.5 cm irregular lesion in the suprasellar region. Our preoperative presumptive diagnosis was craniopharyngioma. The patient underwent an extended endoscopic transsphenoidal approach, the mass was subtotally removed. An endoscopic endonasal repair was needed due to the cerebrospinal fluid (CSF) leak. However, 1 month later, the patient got disturbance of consciousness because of the hydrocephalus. Ventriculoperitoneal shunt was used to solve the problem. Pathological findings were compatible with hemangioblastoma. Suprasellar hemangioblastoma is very rare. Any highly vascular lesions located in the suprasellar region should alert the surgeon to the possibility of hemangioblastoma. Extended endoscopic transsphenoidal approach adopted by us should not be the first choice of the treatment procedure for this kind of large and vascular tumor.

Abstract
OBJECT The proximity of craniopharyngiomas to vital neurovascular structures and their high recurrence rates make them one of the most challenging and controversial management dilemmas in neurosurgery. Endoscopic endonasal surgery (EES) has recently been introduced as a treatment option for both pediatric and adult craniopharyngiomas. The object of the present study was to present the results of EES and analyze outcome in both the pediatric and the adult age groups. METHODS The authors retrospectively reviewed the records of patients with craniopharyngioma who had undergone EES in the period from June 1999 to April 2011. RESULTS Sixty-four patients, 47 adults and 17 children, were eligible for this study. Forty-seven patients had presented with primary craniopharyngiomas and 17 with recurrent tumors. The mean age in the adult group was 51 years (range 28-82 years); in the pediatric group, 9 years (range 4-18 years). Overall, the gross-total resection rate was 37.5% (24 patients); near-total resection (> 95% of tumor removed) was 34.4% (22 patients); subtotal resection (≥ 80% of tumor removed) 21.9% (14 patients); and partial resection (< 80% of tumor removed) 6.2% (4 patients). In 9 patients, EES had been combined with radiation therapy (with radiosurgery in 6 cases) as the initial treatment. Among the 40 patients (62.5%) who had presented with pituitary insufficiency, pituitary function remained unchanged in 19 (47.5%), improved or normalized in 8 (20%), and worsened in 13 (32.5%). In the 24 patients who had presented with normal pituitary function, new pituitary deficit occurred in 14 (58.3%). Nineteen patients (29.7%) suffered from diabetes insipidus at presentation, and the condition developed in 21 patients (46.7%) after treatment. Forty-four patients (68.8%) had presented with impaired vision. In 38 (86.4%) of them, vision improved or even normalized after surgery; in 5, it remained unchanged; and in 1, it temporarily worsened. One patient without preoperative visual problems showed temporary visual deterioration after treatment. Permanent visual deterioration occurred in no one after surgery. The mean follow-up was 38 months (range 1-135 months). Tumor recurrence after EES was discovered in 22 patients (34.4%) and was treated with repeat surgery (6 patients), radiosurgery (1 patient), combined repeat surgery and radiation therapy (8 patients), interferon (1 patient), or observation (6 patients). Surgical complications included 15 cases (23.4%) with CSF leakage that was treated with surgical reexploration (13 patients) and/or lumbar drain placement (9 patients). This leak rate was decreased to 10.6% in recent years after the introduction of the vascularized nasoseptal flap. Five cases (7.8%) of meningitis were found and treated with antibiotics without further complications. Postoperative hydrocephalus occurred in 7 patients (12.7%) and was treated with ventriculoperitoneal shunt placement. Five patients experienced transient cranial nerve palsies. There was no operative mortality. CONCLUSIONS With the goal of gross-total or maximum possible safe resection, EES can be used for the treatment of every craniopharyngioma, regardless of its location, size, and extension (excluding purely intraventricular tumors), and can provide acceptable results comparable to those for traditional craniotomies. Endoscopic endonasal surgery is not limited to adults and actually shows higher resection rates in the pediatric population.

Abstract
OBJECT Accurate diagnosis of the topographical relationships of craniopharyngiomas (CPs) involving the third ventricle and/or hypothalamus remains a challenging issue that critically influences the prediction of risks associated with their radical surgical removal. This study evaluates the diagnostic accuracy of MRI to define the precise topographical relationships between intraventricular CPs, the third ventricle, and the hypothalamus. METHODS An extensive retrospective review of well-described CPs reported in the MRI era between 1990 and 2009 yielded 875 lesions largely or wholly involving the third ventricle. Craniopharyngiomas with midsagittal and coronal preoperative and postoperative MRI studies, in addition to detailed descriptions of clinical and surgical findings, were selected from this database (n = 130). The position of the CP and the morphological distortions caused by the tumor on the sella turcica, suprasellar cistern, optic chiasm, pituitary stalk, and third ventricle floor, including the infundibulum, tuber cinereum, and mammillary bodies (MBs), were analyzed on both preoperative and postoperative MRI studies. These changes were correlated with the definitive CP topography and type of third ventricle involvement by the lesion, as confirmed surgically. RESULTS The mammillary body angle (MBA) is the angle formed by the intersection of a plane tangential to the base of the MBs and a plane parallel to the floor of the fourth ventricle in midsagittal MRI studies. Measurement of the MBA represented a reliable neuroradiological sign that could be used to discriminate the type of intraventricular involvement by the CP in 83% of cases in this series (n = 109). An acute MBA (< 60°) was indicative of a primary tuberal-intraventricular topography, whereas an obtuse MBA (> 90°) denoted a primary suprasellar CP position, causing either an invagination of the third ventricle (pseudointraventricular lesion) or its invasion (secondarily intraventricular lesion; p < 0.01). A multivariate model including a combination of 5 variables (the MBA, position of the hypothalamus, presence of hydrocephalus, psychiatric symptoms, and patient age) allowed an accurate definition of the CP topography preoperatively in 74%-90% of lesions, depending on the specific type of relationship between the tumor and third ventricle. CONCLUSIONS The type of mammillary body displacement caused by CPs represents a valuable clue for ascertaining the topographical relationships between these lesions and the third ventricle on preoperative MRI studies. The MBA provides a useful sign to preoperatively differentiate a primary intraventricular CP originating at the infundibulotuberal area from a primary suprasellar CP, which either invaginated or secondarily invaded the third ventricle.

Abstract
One of the most challenging parasellar tumors, the craniopharyngioma was first described by Friedrich Albert von Zenker in 1857. Following improved understanding of pituitary gland physiology and development, Jakob Erdheim became the first to accurately describe the histopathological characteristics of a craniopharyngioma. Babinski's described the clinical presentation of these patients, with "sexual infantilism and dystrophic adiposity." The first successful surgical resection of a craniopharyngioma was performed by A. E. Halstead of Chicago of July 21st, 1909. Harvey Cushing embraced the transsphenoidal approach for the majority of his pituitary operations, but favored the transcranial approach for craniopharyngiomas. The introduction of antibiotics, corticosteroids, and microscopy significantly improved surgical outcomes. As technology improved, trans-cranial and transsphenoidal approaches were implemented depending on tumor characteristics. Adjuvant therapy, such as stereotactic radiosurgery, radioisotope brachytherapy, and intracapsular chemotherapy have improved overall tumor control rates and decreased the incidence of complications. Building on over 100 years of surgery for "the most formidable of intracranial tumors," results continue to improve. Regardless, challenges continue to remain requiring surgical insight and innovation.

Abstract
Few pituitary adenomas require removal through a transcranial route. This may be associated with more significant morbidity and mortality, compared to the transsphenoidal approach. An endoscopic, extended, transplanum-transtuberculum approach (ETTA) in selected pituitary adenomas may offer an alternative to the transcranial route. We describe our technique and experience of ETTA in pituitary adenomas over 10 years. Between 2000 and 2010, we performed 700 endoscopic endonasal procedures for pituitary adenomas. Nineteen patients (13 men; mean age, 48 years; range, 22-76 years) underwent 22 ETTAs. Thirteen patients had non-functioning adenomas. Three tumor groups were identified: (1) tumors developing in or around the pituitary stalk; (2) tumours with sub- frontal extension and (3) tumours with a major extrasellar component. Mean follow-up was 37 months (range 6-72 months). Gross total resection was achieved in 11 procedures (no recurrences), with partial tumour resection in 11 procedures. Of the 12 patients with visual symptoms, ten improved. Of eight patients with hormonal hypersecretion four were cured. Complications included CSF leak (14%), haemorrhage (9%), hemiplegia (5%). There were no mortalities. Experience using the ETTA for pituitary adenomas is limited because it is indicated in highly selected cases (3.1% of our series). An absolute indication is represented by ectopic secreting pituitary stalk/peri-stalk adenomas. ETTA is a useful option in midline frontal adenomas and adenomas with a major extrasellar component, but has a higher morbidity than that seen in the standard transsphenoidal approach. A study comparing ETTA versus transcranial resection is highly desirable.

The trochlear nerve: microanatomic and endoscopic study. Neurosurg Rev 2012; 36:227-37; discussion 237-8. [PMID: 23065103 DOI: 10.1007/s10143-012-0426-x] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2011] [Revised: 06/20/2012] [Accepted: 07/15/2012] [Indexed: 10/27/2022]
Abstract
The purpose of the present study was to analyze the relationships of the trochlear nerve with the surrounding structures through both endoscopic and microscopic perspectives. The aim was to assess the anatomy of the nerve and to carry out a thorough description of its entire course. A comprehensive anatomically and clinically oriented classification of its different segments is proposed. Forty human cadaveric fixed heads (20 specimens) were used for the dissection. The arterial and venous systems were injected with red and blue colored latex, respectively, in the transcranial dissection. For illustrative purposes, the arterial vessels were injected alone in endoscopic endonasal procedures. A CT scan was carried out on every head. Median supracerebellar infratentorial, subtemporal, fronto-temporo-orbito-zygomatic, and endoscopic endonasal transsphenoidal approaches were performed to expose the entire pathway of the nerve. A navigation system was used during the dissection process to perform the measurements and postoperatively to reconstruct, using dedicated software, a three-dimensional model of the different segments of the nerve. The trochlear nerve was divided into five segments: cisternal, tentorial, cavernous, fissural, and orbital. Detailed and comprehensive examination of the basic anatomical relationships through the view of transcranial, endoscope-assisted, and pure endoscopic endonasal approaches was achieved. As a result of a thorough study of its intra- and extradural pathways, an anatomic-, surgically, and clinically based classification of the trochlear nerve is proposed. Precise knowledge of the involved surgical anatomy is essential to safely access the supracerebellar region, middle fossa, parasellar area, and orbit.

Abstract
BACKGROUND The endoscopic, endonasal, extended transsphenoidal approach is a minimal-access technique for managing craniopharyngiomas. Outcome measures such as return to employment and body mass index (BMI) have not been reported and are necessary for comparison with open transcranial approaches. Most prior reports of the endoscopic, endonasal approach have reported unacceptably high cerebrospinal fluid (CSF) leak rates. OBJECTIVE To assess the outcome of endoscopic, endonasal surgery in a consecutive series of craniopharyngiomas with special attention to extent of resection, CSF leak, return to employment, and BMI. METHODS Twenty-six surgeries were performed on 24 patients at Weill Cornell Medical College-New York Presbyterian Hospital. Five patients had recurrent lesions. Gross-total resection (GTR) was attempted in 21 surgeries. Indications for intended subtotal resection were advanced age, medical comorbidities, preservation of pituitary function, and hypothalamic invasion. RESULTS Mean tumor diameter was 2.9 cm. GTR (18 surgeries) or near-total (>95%) resection (2 surgeries) was achieved in 95% when GTR was the goal. Seven patients received postoperative radiation therapy. Mean follow-up was 35 months with no recurrences in GTR cases and stable disease in all patients at last follow-up. Vision improved in 77%. Diabetes insipidus and panhypopituitarism developed in 42% and 38%, respectively. A more than 9% increase in BMI occurred in 39%; 69% returned to their preoperative profession/schooling. The postoperative CSF leak rate was 3.8%. CONCLUSION Minimal-access, endoscopic, endonasal surgery for craniopharyngioma can achieve high rates of GTR with low rates of CSF leak. Return to employment and obesity rates are comparable to microscope-assisted transcranial and transsphenoidal reports.

Abstract
Supratentorial hemangioblastoma is a rare form of hemangioblastoma; little information is available regarding prognosis, treatment, and clinical characteristics, because the available literature is primarily composed of case reports and small case series. Therefore, we performed a systematic review of the literature to analyze clinical characteristics, disease progression, and surgical outcomes with respect to survival for supratentorial hemangioblastomas. The rate of progression-free survival (PFS) was determined using Kaplan-Meier analysis. Differences in categorical factors, including location of tumor and diagnosis of von Hippel-Lindau (VHL) disease, were analyzed using the Pearson χ(2) test. A total of 106 articles met the search criteria, which combined for a total of 132 patients. Of the patients with supratentorial tumors, 60% had VHL disease, and 31 (84%) of 37 patients with tumors in the sellar/suprasellar region had associated VHL (χ(2), P < .001). Five-year PFS for gross-total resection and subtotal resection were 100% and 53%, respectively (Log rank, P < .01). On the basis of our analysis of the literature on published cases of supratentorial hemangioblastoma, gross-total resection appears to be superior to other treatment modalities in extending PFS. Von Hippel-Lindau disease is positively correlated with supratentorial hemangioblastoma when compared with non-supratentorial CNS hemangioblastomas, particularly when present in the sellar/suprasellar region.

Abstract
Giant (>4 cm) pituitary macroadenomas often require surgery to decompress the optic nerves. Compared with traditional open or transsphenoidal microscopic methods, the extended endoscopic endonasal transsphenoidal approach offers the potential for aggressive resection via a minimal access corridor. We conducted a systematic review of the literature to further our understanding of the role of endoscopy in the management of these challenging lesions. MEDLINE search of the modern literature (1995-2010) to identify surgical series for pediatric and adult pituitary adenomas >4 cm in maximal diameter. Patient and tumor characteristics, resection, morbidity and visual outcome were compared by approach. Chi-square and Fisher's exact tests with post-hoc Bonferroni analysis were used for statistical analyses. Sixteen studies (478 patients) were included. Compared with the open cohort, the endoscopic cohort had higher rates of gross total resection (47.2% vs. 9.6%; P < 0.003) and improved visual outcome (91.1% vs. 45.7%; P < 0.003). The microscopic transsphenoidal cohort had lower rate of total resection and worse visual outcomes than the endoscopic group. There were no instances of postoperative CSF leak reported in the endoscopic group. The transcranial group had a higher rate perioperative mortality compared to the transsphenoidal group (P = 0.004). In select cases, the endoscopic endonasal approach is safe and effective for the treatment of giant pituitary adenomas, with the potential for gross total resection and improved visual outcome. CSF leak, which is a major limitation of the endonasal approach, may be avoided using meticulous multi-layer closure and vascularised nasoseptal flaps.

Abstract
AIMS Tuberculum sellae meningiomas (TSMs) are usually removed through a transcranial approach. Recently, the sublabial transsphenoidal microscopic approach has been used to remove such tumours. More recently, endonasal extended transsphenoidal approach is getting popular for removal of tuberculum sellae meningioma. Here, we describe our initial experience of endonasal extended transsphenoidal approach for removal of suprasellar meningiomas in six consecutive cases. MATERIALS AND METHOD Six patients (four female and two male) who presented for headache and visual loss were investigated with MRI of brain that showed tuberculum sellae meningioma compressing visual apparatus. Average size was 3 × 3 cm in three cases and 4 × 4 cm in rest of the three. All patients underwent endoscopic endonasal extended transsphenoidal tumour removal, but in two patients with large tumour, microscopic assistance was needed. Complete tumour removal was done in all cases except one case where perforators seemed to be encased by the tumour and resulted in incomplete removal. The surgical dural and bony defects were repaired in all patients with thigh fat graft. Nasal packing was not used, but inflated balloon of Foley's catheter was used to keep fat in position. RESULT There was mild postoperative cerebrospinal fluid (CSF) leakage in one patient on the fourth postoperative day after removal of lumbar CSF drain and stopped spontaneously on the seventh postoperative day. There were no postoperative CSF leaks or meningitis in the rest of the cases. In one patient, there was visual deterioration due to pressure on optic nerve by grafted fat and improved within 4 weeks. At 4 months after surgery, three patients had normal vision, two patients improved vision comparing with that of preoperative state but with some persisting deficit; one patient had static vision, no new endocrinopathy and no residual tumour on MRI in five cases but residual tumour in remaining case was static at the end of the ninth month. CONCLUSION The endoscopic endonasal extended transsphenoidal approach appears to be an effective minimally invasive method for removing relatively small to medium tuberculum sellae meningiomas. With more experience of the surgeon, larger tuberculum sellae meningioma may be removed by purely endoscopic techniques in near future.

Abstract
Little data exists comparing endoscopic endonasal approaches to pathology of the anterior skull base with more traditional transcranial and transsphenoidal microscopic approaches. In order to more fully characterize the role of endoscopy in the management of pathology of the anterior cranial base, we conducted a systematic review of case series and case reports documenting surgical and clinical outcomes. We found that for craniopharyngiomas, clival chordomas, esthesioneuroblastomas and giant pituitary adenomas, the endonasal endoscopic approach can result in equivalent or higher rates of gross total resection than open approaches. For meningiomas, however, open transcranial approaches are still able to achieve higher rates of total resection. CSF leak rates are higher for patients undergoing endoscopic surgery for meningiomas and craniopharyngiomas, but not for chordomas, esthesioneuroblastomas or giant pituitary adenomas. In certain patients, the endonasal endoscopic approach may be a safe and effective alternative for the treatment of a wide variety of skull base pathology, particularly those with small midline tumours.

Abstract
OBJECT The tuberculum sellae is a bony elevation ridge that lines up the anterior aspect of the sella, dividing it from the chiasmatic groove. The recent use of the endoscopic endonasal transtuberculum approach has provided surgeons with a method to reach the suprasellar area, offering a new surgical point of view somehow "opposite" of this area. The authors of this study aimed to define the tuberculum sellae as seen from the endoscopic endonasal view while also providing CT-based systematic measurements to objectively detail the anatomical features of such a structure, which was renamed the "suprasellar notch." METHODS The authors analyzed routine skull CT scans from 24 patients with no brain pathology or fractures and measured the interoptic distance at the level of the limbus sphenoidale, the chiasmatic groove sulcal length and width, and the angle of the suprasellar notch. Indeed, the suprasellar notch was defined as the angle between 2 lines, the first passing through the tuberculum sellae midpoint and perpendicular to the cribriform plate, and a second line passing between 2 points, the midpoints of the limbus sphenoidale and the tuberculum sellae. Moreover, the authors performed on 15 cadaveric heads an endoscopic endonasal transplanum transtuberculum approach with the aid of a neuronavigator to achieve a step-by-step comparison with the radiological data. The whole CT scanning set was statistically analyzed to determine the statistical interdependency of the suprasellar notch angle with the other 3 measurements, that is, the sulcal length at the midline, the interoptic distance at the optic canal entrance, and the interoptic distance at the limbus. RESULTS Based on the endoscopic endonasal view and CT imaging analysis, the authors identified a certain anatomical variability and thus introduced a new classification of the suprasellar notch: Type I, angle < 118°; Type II, angle of 118°-138°; and Type III, angle > 138°. They then analyzed the surgical implications of the endoscopic endonasal approach to the suprasellar area, which could be affected by each of these structural types. CONCLUSIONS The new classification identifies 3 different types of suprasellar notch and, accordingly, their surgical relevance. Above all, the authors found that the different types of suprasellar notch can affect the osteodural defect reconstruction technique, namely the positioning/wedging of the buttress in the extradural space. A precise endoscopic anatomical knowledge of the neurovascular and bony relationships--especially in cases of a less pneumatized sphenoid sinus--is crucial when approaching the anterior skull base via a transtuberculum transplanum route.

Abstract
OBJECTIVE Craniopharyngiomas have traditionally represented a challenge for open transcranial or transsphenoidal microscopic neurosurgery because of their anatomical location and proximity to vital neurovascular structures. The extended endoscopic endonasal transsphenoidal approach has been more recently developed as a potentially surgically aggressive, yet minimal access, alternative. To gain a more comprehensive assessment of the benefits and limitations of the various approaches to resection of craniopharyngiomas, we performed a systematic review of the available published reports after endoscope-assisted endonasal approaches and compared their results with transsphenoidal purely microscope-based or transcranial microscope-based techniques. METHODS We performed a MEDLINE search of the modern literature (1995-2010) to identify open and endoscopic surgical series for pediatric and adult craniopharyngiomas. Comparisons were made for patient and tumor characteristics as well as extent of resection, morbidity, and visual outcome. Statistical analyses of categorical variables were undertaken by the use of χ(2) and Fisher exact tests with post-hoc Bonferroni analysis to compare endoscopic, microsurgical transsphenoidal, and transcranial approaches. RESULTS Eighty eight studies, involving 3470 patients, were included. The endoscopic cohort had a significantly greater rate of gross total resection (66.9% vs. 48.3%; P < 0.003) and improved visual outcome (56.2% vs. 33.1%; P < 0.003) compared with the open cohort. The transsphenoidal cohort had similar outcomes to the endoscopic group. The rate of cerebrospinal fluid leakage was greater in the endoscopic (18.4%) and transsphenoidal (9.0%) than in the transcranial group (2.6%; P < 0.003), but the transcranial group had a greater rate of seizure (8.5%), which did not occur in the endonasal or transsphenoidal groups (P < 0.003). CONCLUSIONS The endoscopic endonasal approach is a safe and effective alternative for the treatment of certain craniopharyngiomas. Larger lesions with more lateral extension may be more suitable for an open approach, and further follow-up is needed to assess the long-term efficacy of this minimal access approach.

Abstract
Introduction Hemangioblastomas are rare, benign tumors occurring in any part of the nervous system. Most are found as sporadic tumors in the cerebellum or spinal cord. However, these neoplasms are also associated with von Hippel-Lindau disease. We report a rare case of a sporadic sellar hemangioblastoma that became symptomatic due to pituitary apoplexy. Case presentation An 80-year-old, otherwise healthy Caucasian woman presented to our facility with severe headache attacks, hypocortisolism and blurred vision. A magnetic resonance imaging scan showed an acute hemorrhage of a known, stable and asymptomatic sellar mass lesion with chiasmatic compression accounting for our patient's acute visual impairment. The tumor was resected by a transnasal, transsphenoidal approach and histological examination revealed a capillary hemangioblastoma (World Health Organization grade I). Our patient recovered well and substitutional therapy was started for panhypopituitarism. A follow-up magnetic resonance imaging scan performed 16 months postoperatively showed good chiasmatic decompression with no tumor recurrence. Conclusions A review of the literature confirmed supratentorial locations of hemangioblastomas to be very unusual, especially within the sellar region. However, intrasellar hemangioblastoma must be considered in the differential diagnosis of pituitary apoplexy.

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
BACKGROUND Supratentorial hemangioblastomas are rare lesions, occurring either sporadically or in von Hippel-Lindau disease. OBJECTIVE Following recent advances in our understanding of the natural history of von Hippel-Lindau-associated cerebellar and spinal hemangioblastomas, we conducted a study of the natural history of supratentorial hemangioblastomas in von Hippel-Lindau disease. METHODS We reviewed a series of 18 supratentorial hemangioblastomas in 13 patients with von Hippel-Lindau disease. Clinical, genetic, and serial imaging data and operative records were analyzed. RESULTS Hemangioblastomas were most commonly seen in the temporal lobe. Only 6 tumors had a cyst at diagnosis or during follow-up, and only 6 patients had associated symptoms at presentation or during follow-up. The most frequent clinical presentations were intracranial hypertension and visual loss. Of 14 tumors with documented serial imaging, 13 demonstrated tumor growth. Rates and patterns of tumor growth were unique to each patient. The mechanism of cyst formation described in other locations was also demonstrated in the supratentorial region. Patterns of peritumoral edema and rate of cyst formation seemed to be influenced by the presence of anatomic barriers. Germline VHL mutation was identified in all patients, but no specific genotype-phenotype correlation was found, although a familial predisposition is suggested. CONCLUSION This series illustrates the wide variation in tumor locations, patterns of growth, and edema progression seen in supratentorial hemangioblastomas and adds to our knowledge of the natural history of hemangioblastomas.

Abstract
Retrochiasmatic craniopharyngiomas are challenging tumors to remove given their deep location and proximity to critical neurovascular structures. Complete surgical removal offers the best chance of cure and prevention of recurrence. The endoscopic endonasal extended transsphenoidal approach offers direct midline access to the retrochiasmatic space through a transplanum transtuberculum corridor. Excellent visualization of the undersurface of the optic chiasm and hypothalamus can be obtained to facilitate bimanual extracapsular dissection to permit complete removal of these formidable tumors. In this report the authors review the endoscopic endonasal extended transsphenoidal approach, with specific emphasis on technical operative nuances in removing retrochiasmatic craniopharyngiomas. An illustrative intraoperative video demonstrating the technique is also presented.
