One-step orbit reconstruction using PMMA implants following hyperostotic sphenoid wing meningioma removal: Evolution of the technique in short clinical series. World Neurosurg X 2024; 22:100281. [PMID: 38455245 PMCID: PMC10918255 DOI: 10.1016/j.wnsx.2024.100281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 02/20/2024] [Indexed: 03/09/2024] Open
Abstract
Purpose To report our experience with patient specific implants for one-step orbit reconstruction following hyperostotic SWM removal and to describe the evolution of the technique through three surgical cases. Methods: Three cases of one-step SWM removal and orbit reconstruction are described. All cases are given consecutively to describe the evolution of the technique. Hyperostotic bone resection was facilitated by electromagnetic navigation and cutting guides (templates). Based on a 3D model, silicone molds were made using CAD/CAM. Then PMMA implant was fabricated from these molds. The implant was adjusted and fixed to the cranium with titanium screws after tumor removal. Results: Following steps of the procedure changed over these series: hyperostotic bone resection, implant thickness control, implant overlay features, anatomic adjustments, implant fixation. The proptosis resolved in all cases. In one patient the progressive visual acuity deterioration was recognized during the follow-up. No oculomotor disturbances and no tumor regrowth were found at the follow-up. Conclusion CAD/CAM technologies enable creation of implants of any size and configuration, and thereby, to increase the extent of bony resection and lower the risk of tumor progression. The procedure is performed in one step which decreases the risk of postoperative morbidity.

Song X, Li Z. Coexistence of meningioma and craniofacial fibrous dysplasia: a case series of clinicopathological study and literature review. Orphanet J Rare Dis 2024; 19:30. [PMID: 38287340 PMCID: PMC10826192 DOI: 10.1186/s13023-024-03032-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 01/19/2024] [Indexed: 01/31/2024] Open
Abstract
BACKGROUND The co-existence of meningioma and craniofacial fibrous dysplasia (CFD) is rare. Due to the similar radiological characteristics, it is challenging to differentiate such co-existence from solitary hyperostotic meningioma resulting in a dilemma of prompt diagnosis and appropriate intervention. METHOD We conducted a retrospective review of the data from 21 patients with concomitant meningioma and CFD who were treated at Beijing Tiantan Hospital from 2003 to 2021. We summarized their clinicopathological features and performed a comprehensive literature review. Additionally, we tested the characteristic pathogenic variants in exon 8 and 9 of GNAS gene and the expression of corresponding α-subunit of the stimulatory G protein (Gαs) related to CFD to explore the potential interactions between these two diseases. RESULTS The cohort comprised 4 men and 17 women (mean age, 45.14 years). CFD most commonly involved the sphenoid bone (n = 10) and meningiomas were predominantly located at the skull base (n = 12). Surgical treatment was performed in 4 CFD lesions and 14 meningiomas. Simpson grade I-II resection was achieved in 12 out of the 14 resected meningiomas and almost all of them were classified as WHO I grade (n = 13). The mean follow-up duration was 56.89 months and recurrence was noticed in 2 cases. Genetic study was conducted in 7 tumor specimens and immunohistochemistry was accomplished in 8 samples showing that though GNAS variant was not detected, Gαs protein were positively expressed in different degrees. CONCLUSIONS We presented an uncommon case series of co-diagnosed meningioma and CFD and provided a detailed description of its clinicopathological features, treatment strategy and prognosis. Although a definite causative relationship had not been established, possible genetic or environmental interplay between these two diseases could not be excluded. It was challenging to initiate prompt diagnosis and appropriate treatment for concomitant meningioma and CFD because of its similar radiological manifestations to meningioma with reactive hyperostosis. Personalized and multi-disciplinary management strategies should be adopted for the co-existence of meningioma and CFD.

[PMID: 38161648 PMCID: PMC10753638 DOI: 10.1002/ccr3.8376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 12/05/2023] [Accepted: 12/14/2023] [Indexed: 01/03/2024] Open
Abstract
This study paper's main goal is to report rare cases of skull base meningiomas that exemplify the complexities of diagnosis, therapy, and postoperative care. By describing these rare cases, we hope to advance knowledge of the clinical signs, difficulties, and prognoses of skull base meningiomas in a challenging anatomical setting. In the posterior cranial fossa, our investigation reveals a unique example of skull base meningioma that involved numerous cranial nerves and complex vasculature. A variety of visual abnormalities were present in the patient's clinical presentations, highlighting the wide range of symptoms that these tumors might cause depending on their precise positions. These cases highlight the critical importance of preoperative imaging, including high-resolution MRI and angiography, as well as the diagnostic difficulties these tumors pertain. By reporting these instances, our research adds to the body of knowledge about skull base meningiomas and offers insightful information about the nuances of their therapies. Our findings highlight the importance of individualized treatment plans, interdisciplinary cooperation, and the demand for continued study to better comprehend these convoluted tumors. Such studies are essential for advancing our knowledge of these enigmatic tumors, guiding clinical judgment, and eventually improving patient outcomes. These findings are important because they can fill information gaps, improve treatment plans, and encourage additional research in neuro-oncology. Abstract This study presents a series of three rare cases of skull base meningiomas, emphasizing the complexities in diagnosis, treatment, and postoperative care. The patients' clinical presentations and imaging highlighted the diverse symptoms and challenges associated with these tumors, found in intricate anatomical locations. The cases underscore the crucial role of preoperative high-resolution imaging and angiography in diagnostic accuracy. Surgical intervention, guided by a multidisciplinary approach, is pivotal in managing these demanding cases. Histopathological examinations confirmed atypical meningiomas. The postoperative phases involved meticulous care to ensure optimal recovery and functional outcomes. Our findings contribute to the understanding of skull base meningiomas, emphasizing the need for personalized treatment plans and ongoing research to improve patient outcomes in neuro-oncology.

Surgical Treatment of Spheno-Orbital Meningiomas: A Systematic Review and Meta-Analysis of Surgical Techniques and Outcomes. J Clin Med 2023; 12:5840. [PMID: 37762781 PMCID: PMC10531637 DOI: 10.3390/jcm12185840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 08/29/2023] [Accepted: 09/05/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Spheno-orbital meningiomas (SOMs) are rare tumors arising from the meninges surrounding the sphenoid bone and orbital structures. Surgical resection is the primary treatment approach for SOMs. Several surgical approaches have been described during the decades, including microsurgical transcranial (MTAs), endoscopic endonasal (EEAs), endoscopic transorbital (ETOAs), and combined approaches, and the choice of surgical approach remains a topic of debate. PURPOSE This systematic review and meta-analysis aim to compare the clinical and surgical outcomes of different surgical approaches used for the treatment of SOMs, discussing surgical techniques, outcomes, and factors influencing surgical decision making. METHODS A comprehensive literature review of the databases PubMed, Ovid MEDLINE, and Ovid EMBASE was conducted for articles published on the role of surgery for the treatment of SOMs until 2023. The systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Meta-analysis was performed to estimate pooled event rates and assess heterogeneity. Fixed- and random-effects were used to assess 95% confidential intervals (CIs) of presenting symptoms, outcomes, and complications. RESULTS A total of 59 studies comprising 1903 patients were included in the systematic review and meta-analysis. Gross total resection (GTR) rates ranged from 23.5% for ETOAs to 59.8% for MTAs. Overall recurrence rate after surgery was 20.7%. Progression-free survival (PFS) rates at 5 and 10 years were 75.5% and 49.1%, respectively. Visual acuity and proptosis improvement rates were 57.5% and 79.3%, respectively. Postoperative cranial nerve (CN) focal deficits were observed in 20.6% of cases. The overall cerebro-spinal fluid (CSF) leak rate was 3.9%, and other complications occurred in 13.9% of cases. MTAs showed the highest GTR rates (59.8%, 95%CI = 49.5-70.2%; p = 0.001) but were associated with increased CN deficits (21.0%, 95%CI = 14.5-27.6%). ETOAs had the lowest GTR rates (23.5%, 95%CI = 0.0-52.5%; p = 0.001), while combined ETOA and EEA had the highest CSF leak rates (20.3%, 95%CI = 0.0-46.7%; p = 0.551). ETOAs were associated with better proptosis improvement (79.4%, 95%CI = 57.3-100%; p = 0.002), while anatomical class I lesions were associated with better visual acuity (71.5%, 95%CI = 63.7-79.4; p = 0.003) and proptosis (60.1%, 95%CI = 38.0-82.2; p = 0.001) recovery. No significant differences were found in PFS rates between surgical approaches. CONCLUSION Surgical treatment of SOMs aims to preserve visual function and improve proptosis. Different surgical approaches offer varying rates of GTR, complications, and functional outcomes. A multidisciplinary approach involving a skull base team is crucial for optimizing patient outcomes.

Abstract
INTRODUCTION Lesions affecting the anterior skull base and involving the paranasal sinuses (PNS), nasal cavity (NC), and orbit are infrequent and include predominantly a wide variety of sinonasal malignancies. Less than 3% of intracranial meningiomas extend extracranially and involve PNS and NC. Given their relatively low incidence, little is known about the treatment outcome of this subset of meningiomas. METHODS Systematic literature and retrospective review of own institutional series of midline anterior skull base meningiomas with significant PNS and NC involvement were performed. RESULTS Overall, 21 patients-16 in the literature review group and 5 of our institutional series-were included. Eleven (52.4%) patients had had a prior surgery for midline anterior skull base meningioma. Of patients having reported WHO grade, two were WHO II. Gross total resection was achieved in 16 (76.2%) of patients, utilizing solely transcranial approach in 15 patients, combined endoscopic and transcranial in five patients and purely endoscopic in one patient. Postoperative radiotherapy was administered in three (14.3%) patients, all after total resection via transcranial route, without a history of prior treatment. A postoperative cerebrospinal fluid leak was reported in four (10%) patients, requiring surgical repair in two. There were no reports of postoperative meningitis. No neurological complications were observed except of a reported worsening of vision in one patient. CONCLUSION Midline anterior skull base meningiomas infrequently extend significantly into the PNS and NC. Despite their significant involvement, along with concomitant involvement of orbit, gross total resection is possible in the majority of cases with low morbidity using either purely transcranial or combined endoscopic/transcranial approach.

Abstract
Given the complex and multifaceted nature of resecting giant tumors in the anterior, middle, and, to a lesser extent, the posterior fossa, we present two example strategies for navigating the intricacies of such tumors. The foundational premise of these two approaches is based on a two-stage method that aims to improve the visualization and excision of the tumor. In the first case, we utilized a combined endoscopic endonasal approach and a staged modified pterional, pretemporal, with extradural clinoidectomy, and transcavernous approach to successfully remove a giant pituitary adenoma. In the second case, we performed a modified right-sided pterional approach with pretemporal access and extradural clinoidectomy. This was followed by a transcortical, transventricular approach to excise a giant anterior clinoid meningioma. These cases demonstrate the importance of performing staged operations to address the challenges posed by these giant tumors.

Spheno-Orbital Meningioma and Vision Impairment-Case Report and Review of the Literature. J Clin Med 2022; 12:jcm12010074. [PMID: 36614875 PMCID: PMC9821601 DOI: 10.3390/jcm12010074] [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: 11/17/2022] [Revised: 12/11/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022] Open
Abstract
(1) Background: Spheno-orbital meningioma (SOM) is a very rare subtype of meningioma which arises from the sphenoid ridge with an orbital extension. It exhibits intraosseous tumor growth with hyperostosis and a widespread soft-tissue growth at the dura. The intra-orbital invasion results in painless proptosis and slowly progressing visual impairment. (2) Methods: We present a case of a 46-year-old woman with SOM and compressive optic nerve neuropathy related to it. Her corrected distance visual acuity (CDVA) was decreased to 20/100, she had extensive visual field (VF) scotoma, dyschromatopsia, impaired pattern-reversal visual-evoked potential (PVEP), and decreased thicknesses of the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC), measured with the swept-source optical coherence tomography (SS-OCT), and a pale optic nerve disc in her left eye. Brain CT and MRI showed a lesion at the base of the anterior cranial fossa, involving the sphenoid wing and orbit. Pterional craniotomy and a partial removal of the tumor at the base of the skull and in the left orbit with the resection of the lesional dura mater and bony defect reconstruction were performed. (3) Results: The histological examination revealed meningothelial meningioma (WHO G1). Decreased CDVA and VF defects completely recovered, and the color vision score and PVEP improved following the surgery, but RNFL and GCC remained impaired. No tumor recurrence was observed at a follow-up of 78 months. (4) Conclusions: Optic nerve dysfunction has the capacity to improve once the compression has been relieved despite the presence of the structural features of optic nerve atrophy.

Abstract
Abstract
Background Unilateral non-pulsating proptosis can be caused by lesions with intraorbital extensions compressing the globe including sphenoid wing en plaque meningiomas and paranasal sinuses lesions.
Patients and Methods We operated on 20 patients with unilateral non-pulsating proptosis using fronto-temporo-orbito-zygomatic (FTOZ) approach with orbital reconstruction in six patients. Eighteen patients had sphenoid wing en plaque meningioma, 1 patient had paranasal sinuses fungal infection with intraorbital and intracranial extension, and 1 patient had frontal sinus dermoid with intraorbital extension.
Results Proptosis was corrected in 50% of the patients, improved in 25%, and remained stationary in 25%. Vision improved in three patients, remained stationary in three, and deteriorated in one patient. Two patients had temporary oculomotor ophthalmoplegia that resolved within 3 months.
Conclusion Although it is an invasive approach, FTOZ gives excellent exposure of the orbit and anterolateral skull base that allows the excision of intracranial lesions with orbital extension. If needed, the orbit could be reconstructed easily due to excellent exposure.

Abstract
Background Predominantly intraosseous meningiomas are rare entities that include true primary intraosseous meningiomas (PIM), as well as meningiomas that may show extensive bone involvement, such as en plaque meningiomas. Different hypotheses have been proposed to decipher the origin of PIMs, such as ectopic arachnoid cap cell entrapment during birth or after trauma. Surgical resection is the treatment of choice of such lesions. Case presentation We present a case of a 65-year-old man with an enlarging mass in the parieto-occipital region that grew slowly and progressively over 13 years, following head trauma during a motor vehicle accident. One year prior to presentation, he started experiencing daily holocranial headaches and blurry vision. CT and MRI studies revealed a permeative midline calvarial lesion measuring 14 cm in greatest dimension with extensive periosteal reaction, extension into the subcutaneous soft tissues, subjacent dural thickening and intracranial extension with invasion of the superior sagittal sinus. The favored pre-operative clinical diagnosis was osteosarcoma. The abnormal calvarium was excised and histopathological examination confirmed the diagnosis of a predominantly intraosseous calvarial meningioma, WHO grade I. Conclusions The present case highlights the importance of histopathologic diagnosis in guiding therapeutic decisions and reiterates the necessity of considering PIM or meningiomas with extensive intraosseous component in the differential diagnosis of calvarial masses, even when imaging suggests a neoplasm with aggressive behavior, such as osteosarcoma.

Hormone-associated meningiomas tend to stop growing or decrease in size after cessation of certain progestins, mainly cyproterone acetate. We report three observations on the natural history of hormone-associated intraosseous meningiomas, showing in a first patient that those tumors may grow rapidly under nomegestrol. We then demonstrate the sustained growth of intraosseous hormone-associated meningiomas after cessation of promesgestone and nomegestrol, independently of the intracranial portion, which concurrently decreased in size in the second case or was resected at the time of nomegestrol withdrawal in the third case, thus giving new insights into the tumorigenesis mechanisms of hormone-associated intraosseous meningiomas.

Abstract
Some sphenoid wing meningiomas are associated with a significant hyperostotic reaction of the adjacent sphenoid ridge that may even exceed the size of the intradural mass. The decision-making process and surgical planning based on neuroanatomic knowledge are the mainstays of management of this group of lesions. Given their natural history and biologic behavior, many hyperostosing meningiomas at this location require long-term management analogous to a chronic disease. This is particularly true when making initial decisions regarding treatment and planning surgical intervention, when it is important to take into consideration the possibility of further future interventions during the patient's life span.

Abstract
PURPOSE Advances in surgical approaches have improved access for total or near-total resection of spheno-orbital meningiomas (SOM). Herein, the outcomes of multidisciplinary resection and reconstruction of SOM via frontotemporal orbitozygomatic craniotomy at a single institution are evaluated. METHODS A retrospective chart review was performed of all patients with SOM who underwent joint neurosurgical and oculofacial plastic resection via frontotemporal orbitozygomatic craniotomy between January 1999 and December 2018. Demographic data, clinical presentation, risk factors for meningioma, radiographic imaging, pathology results, postoperative outcomes, and surgical complications were reviewed. The outcome measures assessed included visual acuity, pupillary function, color vision, ocular motility, visual fields, and proptosis. RESULTS A total of 48 patients were identified having had multidisciplinary frontotemporal orbitozygomatic craniotomy for SOM of which 43 met inclusion criteria. A mean follow-up period of 23.9 ± 20.4 months (range 1-60) was observed. There were 35 patients who underwent primary resection and 8 patients who had prior surgical resection. The main presenting complaints were proptosis (88%), headache (44%), and reduced vision (12%). Gross total resection was achieved in 15 patients (35%) while near-total or subtotal resection was achieved in the remainder. Histologic analysis revealed World Health Organization grade I meningioma in 72% of tumors, grade II in 23%, and grade III in 5%. Mean visual acuity (Logarithm of the Minimum Angle of Resolution) improved from 0.24 ± 0.46 preoperatively to 0.09 ± 0.13 postoperatively (p = 0.03). Surgery improved proptosis, with a reduction in mean Hertel exophthalmometry from 22.37 ± 3.78 mm to 17.91 ± 3.84 mm (p < 0.001), of which 80% had no residual proptosis or developed subsequent recurrence. Exophthalmic index calculated by radiologic evaluation also improved from a mean preoperative value of 1.32 ± 0.19 to 1.12 ± 0.13 at the 6-month interval after surgery (p < 0.001). Before surgery, 19 (45%) patients had a relative afferent pupillary reaction with improvement in 9 (24%) after surgery. Of the 14 (33%) patients with preoperative ocular motility deficit, 7 (16%) had resolution of ocular motility deficit postoperatively. The most common surgical complications were temporalis muscle atrophy with temporal hollowing (14%), wound infection (7%), neurogenic strabismus secondary to trochlear nerve palsy (5%), restrictive strabismus (5%), and aponeurotic blepharoptosis (5%). CONCLUSIONS Multidisciplinary frontotemporal orbitozygomatic for resection of SOM is a safe and effective means of tumor removal. It can provide improved visual acuity and proptosis metrics, as well as relief of optic neuropathy and ocular motility deficits.

Abstract
Abstract
Introduction
Spheno-orbital meningiomas are characterized by bone invasion with extensive hyperostosis and possible encroachment into the orbit, infra-temporal fossa, and/or the cavernous sinus that render total surgical excision challenging. The surgical technique utilized is a key factor facilitating complete resection and hence improvement of proptosis and accompanying visual symptoms.
Methods
This is a retrospective study of twenty-two patients (including 4 recurrent cases) with meningioma en-plaque, presenting with hyperostosis and proptosis. We describe the surgical approaches used, technique, and extent of resection in addition to postoperative outcome.
Results
In twenty patients, the pterional approach was used, while two patients were operated on via the mini orbito-zygomatic approach. Total resection of the tumor was achieved in 10 cases (45.5%), subtotal in 6 (27.3%), partial in 5 (22.7%), and in 1 case, injury to the internal carotid artery lead to premature termination of surgery. Seventeen patients (77.3%) had improvement of proptosis, 2 (9.1%) had partial improvement, and 2 (9.1%) had no improvement at 3 months of follow-up. Post-operative morbidities include cerebrospinal fluid leak, infection, and hydrocephalus, each occurred in one (4.5%) different case.
Conclusions
Proper drilling of the lateral and superior orbital walls with excision of any intra-orbital soft tissue components is all key points for better surgical resection and clinical regression of proptosis. However, factors such as extension of the hyperostosis to the infra-temporal fossa or medial orbital wall, tumor invasion of the cavernous sinus, or adherence of tumor to the orbital muscles, prevent total excision.

Abstract
Purpose The effectiveness and safety of surgery for spheno‐orbital meningiomas remains subject of debate, as studies often describe different surgical approaches and reconstruction techniques with very heterogeneous outcomes. We aimed to systematically summarize and analyse the literature on spheno‐orbital meningiomas regarding presenting symptoms, surgical techniques, outcomes and complications. Methods Studies were retrieved from eight databases. Original articles were included if in ≥5 patients presenting symptoms, surgical treatment and outcomes were described. Fixed‐ and random‐effects meta‐analysis was performed to estimate weighted percentages with 95%CIs of presenting symptoms, outcomes and complications. Results Thirty‐eight articles were included describing 1486 patients. Proptosis was the most common presenting symptom (84%; 95%CI 76–91%), followed by unilateral visual acuity deficits (46%; 95%CI 40–51%) and visual field deficits (31%; 95%CI 20–43%). In 35/38 studies (92%), a pterional craniotomy was used. Decompression of the optic canal (82%) and the superior orbital fissure (66%) was most often performed, and usually dural (47%) and bony defects (76%) were reconstructed. In almost all patients, visual acuity (91%; 95%CI 86–96%), visual fields (87%; 95%CI 70–99%) and proptosis (96%; 95%CI 90–100%) improved. Furthermore, surgery showed improvement in 96% (95%CI 78–100%) for both diplopia and ophthalmoplegia. The most common surgical complications were hypesthesia (19%; 95%CI 10–30%), ptosis and diplopia (both 17%; 95%CI, respectively, 10–26% and 5–33%) and ophthalmoplegia (16%; 95%CI 10–24). Conclusion Patients with spheno‐orbital meningioma usually present with proptosis or unilateral decreased visual acuity. Surgery shows to be effective in improving visual acuity and visual field deficits with mostly minor and well‐tolerated complications.

Abstract
We describe an unusual cause of cranial dural thickening in an elderly female with a chronic meningeal inflammatory process. A 70-year-old ethnically Chinese, Singaporean female presented with a history of chronic daily headache with no other meningeal signs. Serial MRI brains showed progressive pachymeningeal and leptomeningeal enhancement in the left frontal region with underlying vasogenic oedema, similar appearances in the right frontal region to a lesser extent, and persistent inflammatory changes in her bilateral paranasal sinuses. Investigative work-up showed a chronically raised ESR with a normal CRP, negative ANCA, and a chronically raised serum IgA kappa paraprotein. Bone marrow trephine biopsy was suggestive of a low level plasma cell disorder. Olfactory cleft biopsy showed no evidence of IgG4-related disease or vasculitis and no significant plasma cell infiltrate. Histopathological examination from a meningeal biopsy revealed a diagnosis of an en-plaque meningioma (the WHO, 2016; Grade I) causing an unusual granulomatous reaction. We discuss the radiological and histological relations of this rare form of meningioma. Clinicians can consider en-plaque meningioma in the differential diagnosis of linear dural thickening and enhancement.

Abstract
OBJECTIVE Sphenoorbital en plaque meningioma is located in a sensitive and complex cranial region. Therefore the therapeutic approach for this type of tumor is of great importance. We aimed to examine the clinical and radiologic outcomes of patients diagnosed with sphenoid wing en plaque meningioma undergoing surgery. METHODS In this case series, the results of clinical and functional assessments, as well as appearance before and after surgery, were examined in 57 patients with sphenoorbital en plaque meningioma undergoing surgery with the frontotemporal approach during 2007-2017. Data were entered in the designed forms and statistically analyzed. RESULTS Proptosis, headache, and vision impairment were detected in 47 (83%), 33 (58%), and 16 (28%) patients, respectively. Eight (14%) patients complained of diplopia, while 3 (8%) patients complained of ptosis. In all patients, proptosis improved following surgery. Complete treatment of proptosis was reported in 42 cases, and significant improvement was observed in 5 cases. Sixteen patients experienced visual impairment before surgery, 7 of whom showed improvements after surgery, while 1 showed deteriorated visual acuity after surgery. Total tumor resection was achieved in 48 (84%) patients. Tumor relapse was reported in 7 (12.5%) patients during follow-up. One patient had undergone repeated surgery, 1 patient was treated with radiotherapy alone, and 5 patients underwent combined treatment. CONCLUSIONS Total tumor resection can be achieved with minimal complications by using microscopic dissection and sufficient bone and orbital wall resection. An important point in the treatment of these patients is the appropriate restoration of the orbital wall.

Abstract
PURPOSE Surgical resection of spheno-orbital meningioma (SOM) is challenging, requiring a multidisciplinary surgical approach. We present our experience of the surgical management of patients with SOM. METHODS A retrospective analysis of patients with SOM who underwent joint neurosurgical and orbital surgical procedures between January 2000 and June 2017. Pre-operative clinical signs, indication for surgery, surgical complications and post-operative outcomes were recorded. RESULTS Twenty-four operations were performed. Mean age was 49.5 years. Ninety-two percent of patients were female. Pre-operatively mean Snellen acuity vision was 6/12; 13 (54%) had an RAPD; 12 (50%) had reduced colour vision; 16 (67%) had a visual field defect. The majority (21 patients, 88%) had proptosis (average 4.5 mm ± 2.8 mm). The indication for surgery was evidence of visual dysfunction in 17 (71%), the remaining 7 (29%) had high risk of visual loss clinically or radiologically. Three-months post operatively, vision was stable in 13 (58%), improved in 6 (21%) and worse in 5 (17%). Average long-term follow-up was 82 months (1-220). Fourteen (58%) maintain improved or stable visual function. Four (17%) had reduced vision due to regrowth of the tumour at an average of 24 months. CONCLUSION SOMs are very challenging to treat surgically. In this cohort the patients were predominantly young females with aggressive disease. Visual function was improved or stabilised in 79% of the patients.

Abstract
OBJECTIVE Hyperostosing sphenoid wing meningiomas cause bony hyperostosis that may extend into the orbit, resulting in proptosis, restriction of extraocular movements, and/or compressive optic neuropathy. The extent of bony removal necessary and the optimal reconstruction strategy to prevent enophthalmos is debated. Herein, the authors present their surgical outcomes and reconstruction results. METHODS This is a retrospective review of 54 consecutive patients undergoing resection of sphenoid wing meningiomas associated with bony hyperostosis. The majority of cases were operated on by the senior author. Extent of tumor resection, volumetric bone resection, radiographic exophthalmos index, complications, and recurrence were analyzed. RESULTS The median age of the cohort was 52.1 years, with women comprising 83% of patients. Proptosis was a presenting symptom in 74%, and 52% had decreased visual acuity. The WHO grade was I (85%) or II (15%). The median follow-up was 2.6 years. On volumetric analysis, a median 86% of hyperostotic bone was resected. Gross-total resection of the intracranial tumor was achieved in 43% and the orbital tumor in 27%, and of all intracranial and orbital components in 20%. Orbital reconstruction was performed in 96% of patients. Postoperative vision was stable or improved in 98% of patients and diplopia improved in 89%. Postoperative complications occurred in 44% of patients, and 26% of patients underwent additional surgery for complication management. The most frequent complications were medical complications and extraocular movement deficits. The median preoperative exophthalmos index was 1.26, which improved to 1.12 immediately postoperatively and to 1.09 at the 6-month follow-up (p < 0.001). Postoperatively, 18 patients (33%) underwent adjuvant radiotherapy after subtotal resection. Tumors recurred/progressed in 12 patients (22%). CONCLUSIONS Resection of hyperostosing sphenoid wing meningiomas, particularly achieving gross-total resection of hyperostotic bone with a good aesthetic result, is challenging and associated with notable medical and ocular morbidity. Recurrence rates in this series are higher than previously reported. Nevertheless, the authors were able to attain improvement in proptosis and visual symptoms in the majority of patients by using a multidisciplinary approach.

Abstract
Background En plaque meningiomas are a rare subtype of meningiomas that are frequently encountered in the spheno-orbital region. Characterized by a hyperostotic and dural invasive architecture, these tumors present unique diagnostic and treatment considerations. Objective The authors conduct a narrative literature review of clinical reports of en plaque meningiomas to summarize the epidemiology, clinical presentation, diagnostic criteria, and treatment considerations in treating en plaque meningiomas. Additionally, the authors present a case from their own experience to illustrate its complexity and unique features. Methods A literature search was conducted using the MEDLINE database using the following terminology in various combinations: meningioma , meningeal neoplasms, en plaque , skull base , spheno-orbital, and sphenoid wing . Only literature published in English between 1938 and 2018 was reviewed. All case series were specifically reviewed for sufficient data on treatment outcomes, and all literature was analyzed for reports of misdiagnosed cases. Conclusion En plaque meningiomas may present with a variety of symptoms according to their location and degree of bone invasion, requiring a careful diagnostic and treatment approach. While early and aggressive surgical resection is generally accepted as the optimal goal of treatment, these lesions require an individualized approach, with further investigation needed regarding the role of new therapies.

Abstract
OBJECTIVE Sphenoorbital meningioma (SOM) is a unique skull base tumor, characterized by infiltrative involvement and hyperostosis primarily of the lesser wing of sphenoid bone, with frequent involvement of the orbital compartment. SOM often manifests with proptosis and visual impairment. Surgical technique and outcome are highly variable among studies reported in the literature. The authors present a single-surgeon experience with SOM. METHODS A retrospective review of a prospectively maintained institutional database was performed. A blinded imaging review by 2 study team members was completed to confirm SOM, after which chart review was carried out to capture demographics and outcomes. All statistical testing was completed using JMP Pro version 14.1.0, with significance defined as p < 0.05. RESULTS Forty-seven patients who underwent surgery between 2000 and 2017 were included. The median age at surgery was 47 years (range 36-70 years), 81% of patients were female, and the median follow-up was 43 months (range 0-175 months). All operations were performed via a frontotemporal craniotomy, orbitooptic osteotomy, and anterior clinoidectomy, with extensive resection of all involved bone and soft tissue. Preoperatively, proptosis was noted in 44 patients, 98% of whom improved. Twenty-eight patients (60%) had visual deficits before surgery, 21 (75%) of whom improved during follow-up. Visual field defect other than a central scotoma was the only prognostic factor for improvement in vision on multivariate analysis (p = 0.0062). Nine patients (19%) had recurrence or progression during follow-up. CONCLUSIONS SOM is a unique skull base tumor that needs careful planning to optimize outcome. Aggressive removal of involved bone and periorbita is crucial, and proptosis and visual field defect other than a central scotoma can improve after surgery.

Abstract
BACKGROUND Spheno-orbital meningiomas are complex tumours involving the sphenoid wing and orbit. Various surgical strategies are available but treatment remains challenging and patients often require more than one surgical procedure. This study evaluated whether smaller surgical approaches and newer reconstructive methods impacted the surgical and clinical outcomes of patients undergoing repeat surgery. METHODS We retrospectively analysed the medical records of consecutive patients who underwent surgery for a spheno-orbital meningioma at a single tertiary centre between 2005 and 2016. We recorded procedural details and analysed complications, postoperative visual status and patient-reported cosmetic outcome. RESULTS Thirty-four procedures were performed in 31 patients (M:F 12:22, median age 49 years) including 19 (56%) primary operations and 15 (44%) repeat procedures. Seven patients (20.5%) had a pterional craniotomy, 19 (56%) had a standard orbitozygomatic craniotomy and 8 (23.5%) underwent a modified mini-orbitozygomatic craniotomy. Calvarial reconstruction was required in 19 cases with a variety of techniques used including titanium mesh (63%), PEEK (26%) and split calvarial bone graft (5%). Total tumour resection (Simpson grade I-II) was significantly higher in patients undergoing primary surgery compared with those having repeat surgery (41% and 0%, respectively; p = 0.0036). Complications occurred in 14 cases (41%). Proptosis improved in all patients and visual acuity improved or remained stable in 93% of patients. Cosmetic outcome measures were obtained for 18 patients (1 = very poor; 5 = excellent): 1-2, 0%; 3, 33%; 4, 28%; 5, 39%. Tumour recurrence requiring further surgery occurred in four patients (12%). There was no significant difference in clinical outcomes between patients undergoing primary or repeat surgery. CONCLUSION Spheno-orbital meningiomas are highly complex tumours. Surgical approaches should be tailored to the patient but good clinical and cosmetic outcomes may be achieved with a smaller craniotomy and custom-made implants, irrespective of whether the operation is the patient's first procedure.

Abstract
OBJECTIVE To evaluate surgical outcome and reconstruction of bone defects after excision of sphenoid meningioma enplaque. PATIENT AND METHODS Between June 2012 and May 2016, a series of 15 patients presented by proptosis attended to neurosurgery departments, Assiut university hospital, Qena university hospital, South Valley University and, These patients were diagnosed with sphenoid meningioma enplaque by fulfilling its criteria by neuroimaging (sheet-like meningioma and hyperostosis). All patients received preoperative imaging investigations including Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) to evaluate the extension of both tumor components - soft tissue and bone involvement. Fifteen patients were operated by pterional approach under general anesthesia. RESULTS Fifteen patients with meningioma enplaque were treated surgically. The mean age of patients at the time of admission was 46.5 years, age ranged between 35-56 years. 80% of patients were females (female to male ratio was 4:1). Ten (66.7%) patients have left sided lesion representing. Proptosis was the main presented manifestation in all patients. Complete tumor excision was done in 10 patients while incomplete excision was done in the rest of patients. Proptosis was improved post-operatively in patients presented by it: Ten (66.7%) patients had complete improvement while the other five (33.3%) patients improved significantly. No mortality occurred in our study. A mean follow-up period of 2.1 years (range: 4 months to 4 years), three (20%) patients have tumor recurrence. CONCLUSIONS Total excision of Sphenoid meningioma enplaque carries difficulties and high rate of post-operative morbidity. Early detection with experienced neurosurgeons, microsurgical techniques and availability of high speed drill decrease the risk of post-operative morbidity. Reconstruction of dural and bone defect is very important regarding functional and cosmetic aspects.

Abstract
OBJECTIVE Patients with atypical and malignant (WHO Grade II and III) meningiomas have a worse prognosis than patients with benign (WHO Grade I) meningiomas. However, there is limited understanding of the pathological risk factors that affect long-term tumor control following combined treatment with surgery and radiation therapy. Here, the authors identify clinical and histopathological risk factors for the progression and/or recurrence (P/R) of high-grade meningiomas based on the largest series of patients with atypical and malignant meningiomas, as defined by the 2007 WHO classification. METHODS Patients diagnosed with WHO Grade II and III meningiomas between 2007 and 2014 per the WHO 2007 criteria and treated with both surgery and external beam radiation therapy were retrospectively reviewed for clinical and histopathological factors at the time of diagnosis and assessed for P/R outcomes at the last available follow-up. RESULTS A total of 76 patients met the inclusion criteria (66 Grade II meningiomas, 10 Grade III meningiomas). Median follow-up from the time of pathological diagnosis was 52.6 months. Three factors were found to predict P/R: Grade III histology, brain and/or bone invasion, and a Ki-67 proliferation rate at or above 3%. The crude P/R rate was 80% for patients with Grade III histology, 40% for those with brain and/or bone involvement (regardless of WHO tumor grade), and 20% for those with a proliferative index ≥ 3% (regardless of WHO tumor grade). The median proliferation index was significantly different between patients in whom treatment failed and those in whom it did not fail (11% and 1%, respectively). CONCLUSIONS In patients with atypical or malignant meningiomas, the presence of Grade III histology, brain and/or bone involvement, and a high mitotic index significantly predicted an increased risk of treatment failure despite combination therapy. These patients can be stratified into risk groups predicting P/R. Patients with high-risk features may benefit from more treatment and counseling than is typically offered currently.

Abstract
Background: En plaque sphenoid wing meningioma is morphological unique in comparison with other intracranial meningiomas, characterized by a carpet-like usually small soft tissue component which invade the dura and extensively involve the bone specially the sphenoid wing and orbit causing significant hyperostosis. Patients & Methods: A retrospective analysis of the clinical data, neuro-radiological features, and operative techniques of eighteen patients underwent transcranio-orbital approach sphenoid wing meningioma presented with proptosis during the period from September 2011 to April 2014 in the neurosurgery department, Mansoura University. Patients age ranged from 38 years to 54 years and there was sex males and twelve females. Chief complaints were progressive proptosis and visual acuity deficits. All patients were operated up on using a fronto-temporal approach with orbital decompression. The extent of tumor resection and postoperative complications were investigated. Results: Total removal was achieved in fourteen cases (77.8%) over a mean follow-up period of 36 months. Pathological examination showed that twelve patients (66.67%) were meningothelial meningiomas. After surgery, proptosis improved in all patients, visual acuity improved in fifteen patients (83.3%). Cerebrospinal fluid leakage was found in one patient. There were no operation-related deaths or other significant complications. Four patients had residual tumor (22.2%); two of them underwent surgical re-attack of the tumor and the other two cases were sent for gamma knife radio-surgery. Conclusions: Sphenoid wing meningioma en plaque, mainly meningothelial meningiomas, are characterized by the associated bony hyperostosis that gives them a distinct radiological appearance. The bony hyperostosis is of neoplastic nature and is responsible for many of the clinical manifestation of such tumors and hence should be totally drilled to achieve cure and avoid recurrence. Extensive tumor removal is crucial for correction of proptosis and adequate visual decompression to achieve satisfactory cosmetic and functional outcome.

Abstract
Meningiomas-en-plaque (MEP) comprise 2.5% of all meningiomas. While they typically arise in the sphenoid wing, convexity MEP are comparatively rare and are often confused with meningeal sarcoidosis, osteoma, tuberculoma, or fibrous dysplasia, with very little information published in the literature. We conducted a literature review on PubMed of English-only articles using a keyword search. All studies that described reports of convexity MEP were reviewed for patient demographics, presenting symptoms, radiological reports, surgical management, recurrence rates, histopathological presentation, post-operative complications, and follow-up. This resulted in 12 papers comprising 22 cases of convexity MEP. Seventeen (77%) of the 22 patients were female with an average age of 53.2years. Intitial presenting symptoms included headache in 12/20 (60%), hemiparesis in 5/20 (25%), and visual symptoms in 1/20 (5%). Of the 14 patients who underwent surgical resection, only four were reported as gross total resection. Twelve reports had associated pathology reports, with all 12 tumors graded as World Health Organization Grade I. Convexity MEP, while rare, present a challenge with regard to correct diagnosis and subsequent resection. The easier accessibility of these meningiomas predicts higher surgical success rates and incidence of total resection, though care must be taken to ensure gross total removal of tumor, dural attachments, and any overlying hyperostotic bone. Though hyperostosis is frequently observed with this variant of meningioma, it is neither exclusive nor wholly indicative of MEP. Due to its rarity in both clinical practice and the literature, further studies are warranted to identify modern imaging means to correctly diagnose this condition.

Abstract
BACKGROUND Sphenoid wing meningiomas extending to the orbit (ePMSW) are currently removed through several transcranial approaches. Presenting the largest surgical cohort of hyperostosing ePMSW with the longest follow up period, we will provide data supporting minilateral orbitotomy with excellent exposure for wide resection of all compartments of the tumor. METHODS A retrospective survival analysis is made of the data cumulated prospectively during a period of 34 years, including 88 cases of ePMSW with a mean follow up period of 136.4 months. The impact of preoperative variables upon different outcome measures is evaluated. Standard pterional craniotomy was performed in 12 patients (C) while the other 76 cases underwent the proposed modified lateral miniorbitotomy (LO). RESULTS There were 31 men and 57 women. The age range varied between 12 and 70 years. Patients presented with unilateral exophthalmos (Uex) ranging between 3 and 16 mm. Duration of proptosis before operation varied between 6 months and 16 years. The status of visual acuity (VA) prior to operation was: no light perception (NLP) in 16, light perception (LP) up to 0.2 in 3, 0.3-0.5 in 22, 0.6-0.9 in 24, and full vision in 23 patients. Postoperatively, acceptable cosmetic appearance of the eyes was seen in 38 cases and in 46 mild inequality of < 2 mm was detected. Four cases had mild enophthalmos (En). Among those who had the worst VA, two improved and one became almost blind after operation. The cases with VA in the range of 0.3-0.5 improved. Among those with good VA (0.5 to full vision), 2 became blind, vision diminished in 10, and improved or remained full in the other 35 cases. Tumor recurrence occurred in 33.3% of group C and 10.5% of group LO (P = 0.05). The major determinant of tumor regrowth was the technique of LO (P = 0.008). CONCLUSION Using LO technique, the risky corners involved by the tumor is visualized from the latero-inferior side rather than from the latero-superior avenue. This is the crucial milestone to achieve aggressive removal of all the involved compartments of the lesion. Satisfactory cosmetic result is reported using mini LO technique after widely exposing and removing the hyperostotic bone down to the subtemporal fossa with only simple repair of the dura without cranioplasty.

Abstract
Meningioma is a common primary tumor of central nervous system. However, extracranial extension of the intracranial meningioma is unusual, and mostly accompanied the osteolytic change of the skull. We herein describe an atypical meningioma having extracranial extension with hyperostotic change of the skull. The patient was a 72-year-old woman who presented a large mass in the right frontal scalp and left hemiparesis. Brain magnetic resonance imaging and computed tomography scans revealed an intracranial mass, diffuse meningeal thickening, hyperostotic change of the skull with focal extension into the right frontal scalp. She underwent total removal of extracranial tumor, bifrontal craniectomy, and partial removal of intracranial tumor followed by cranioplasty. Tumor pathology was confirmed as atypical meningioma, and she received adjuvant radiotherapy. In this report, we present and discuss a meningioma en plaque of atypical histopathology having an extracranial extension with diffuse intracranial growth and hyperostotic change of the skull.

Abstract
OBJECT Bone invasion is a major concern in meningioma surgery, since it is predictive of the recurrence of cranial involvement, morbidity, and mortality. Bone invasion has been reported in 20%-68% of studies with histopathologically confirmed data. Unfortunately, radical resection of bone invasion remains challenging. The aim of this study was to assess the role of 5-aminolevulinic acid (5-ALA) fluorescence in guiding the resection of bone-invading meningiomas. To this purpose, the sensitivity, specificity, and positive and negative predictive values of 5-ALA in detecting meningioma bone invasion were evaluated. METHODS Data from 12 patients affected by bone-invading meningiomas (7 with skull base and 5 with convexity meningiomas) who had undergone surgery with the assistance of 5-ALA fluorescence and neuronavigation between July 2012 and March 2013 at the Department of Neurosurgery of Padua were retrospectively analyzed. To evaluate the sensitivity and specificity of 5-ALA fluorescence in detecting meningioma tissue, a pathologist analyzed 98 surgical bone samples under blue light, according to different fluorescence patterns. Magnetic resonance images and CT scans were obtained pre- and postoperatively to determine the extent of bone invasion resection. RESULTS The rate of 5-ALA-induced fluorescence of both tumor and bone invasion was 100%. Based on the pathological examination of bone specimens, 5-ALA presented a sensitivity of 89.06% (95% CI 81.41%-96.71%) and a specificity of 100% in detecting meningioma bone invasion, while the positive and negative predictive values were 100% and 82.93% (95% CI 71.41%-94.45%), respectively. At the postoperative stage, MRI did not detect cases of meningioma bone invasion, whereas CT scans revealed residual hyperostosis in 2 cases. CONCLUSIONS In summary, 5-ALA fluorescence represents a suitable and reliable technique for identifying and removing bone infiltration by meningiomas. However, further studies are needed to prove the clinical consequences of this promising technique in a larger population.

Abstract
Meningiomas are the most common primary intracranial tumour. Although external beam radiotherapy and radiosurgery are well-established treatments, affording local control rates of 85-95% at 10 years, the evidence base is mainly limited to single institution case series. This has resulted in inconsistent practices. It is generally agreed that radiotherapy is an established primary therapy in patients requiring treatment for surgically inaccessible disease and postoperatively for grade 3 tumours. Controversy exists surrounding whether radiotherapy should be upfront or reserved for progression for incompletely excised and grade 2 tumours. External beam radiotherapy and radiosurgery have not been directly compared, but seem to offer comparable rates of control for benign disease. Target volume definition remains contentious, including the inclusion of hyperostotic bone, dural tail and surrounding brain, but pathological studies are shedding some light. Most agree that doses around 50-54 Gy are appropriate for benign meningiomas and ongoing European Organization for Research and Treatment of Cancer and Radiation Therapy Oncology Group studies are evaluating dose escalation for higher risk disease. Here we address the 'who, when and how' of radiotherapy for meningioma.

Abstract
Background: Sphenoid wing en plaque meningiomas are a subgroup of meningiomas defined by its particular sheet-like dural involvement and its disproportionately large bone hyperostosis. En plaque meningiomas represent 2-9% of all meningiomas and they are mainly located in the sphenoid wing. Total surgical resection is difficult and therefore these tumors have high recurrence rates. Methods: Eighteen patients with sphenoid wing en plaque meningiomas surgically treated between January 1998 and December 2008 were included. Clinical, surgical, and follow-up data were retrospectively analyzed. Results: Mean age was 52.2 years and 83% were female. Five patients presented extension of dural component into the orbit and six patients presented cavernous sinus infiltration. Adjuvant radiation therapy was performed in three patients. After a mean follow-up of 4.6 years, five patients developed tumor recurrence - two patients were submitted to surgical treatment and the other three were submitted to radiation therapy. No patient presented recurrence after radiation therapy, whether performed immediately in the postoperative period or performed after recurrence. Patients without tumor extension to cavernous sinus or orbital cavity have the best prognosis treated with surgery alone. When tumor extension involves these locations the recurrence rate is high, especially in cases not submitted to adjuvant radiation therapy. Conclusion: Cavernous sinus and superior orbital fissure involvement are frequent and should be considered surgical limits. Postoperative radiation therapy is indicated in cases with residual tumor in these locations.

Abstract
BACKGROUND Although meningiomas of the spheno-orbital region commonly result in hyperostosis, intraosseous meningiomas, which feature extensive full thickness infiltration of the anterolateral skull base, are rare. In this study, we assess the value of image guidance during surgery for intraosseous spheno-orbital skull-base meningiomas in achieving safe and maximal abnormal bone resection. METHOD Only cases with a full thickness and extensive intraosseous component were included. Image guidance was used to guide drilling of hyperostotic bone. Extensive resulting defects of the orbital wall were reconstructed with titanium mesh. Post-operative CT scans were used to assess completeness of abnormal bone resection in the skull base, and MRI scans used to evaluate residual intradural disease. Operative complications to neurovascular structures in adjacent foramina were recorded. RESULTS Nineteen patients with full-thickness intraosseous spheno-orbital meningiomas underwent image-guided resection. Anterior clinoidectomy to variable extent was necessary in 11 cases with decompression of the optic canal in five. In ten cases, hyperostotic bone was drilled from the middle fossa around the exit foramina of the trigeminal nerve and base of the pterygoid plates. Proptosis was corrected in all cases, and of 11 patients presenting with reduced visual acuity, symptoms improved or stabilized in ten cases. Post-operative CT scans confirmed gross resection of abnormal bone in all cases, but limited residual tumor was present around the cavernous sinus or orbital apex in eight patients. One patient died from a pulmonary embolism, the only mortality of the series. One patient had worsening of pre-existing poor visual acuity, and three patients had worsening of pre-existing ophthalmoplegia. Five patients developed new facial numbness post-operatively, which persisted in three cases. CONCLUSIONS Intra-operative image guidance allowed total or near-total resection of the hyperostotic skull base around the cranial nerve foramina with minimal morbidity in a group of patients with extensive spheno-orbital meningiomas.

Abstract
Objective Medial sphenoid wing meningiomas (SWMs) are relatively common tumors that are associated with significant morbidity and mortality, primarily from their anatomic proximity to many critical neurological and vascular structures. A major complication is visual deterioration. This study aimed to identify predictors of visual outcome following medial SWM resection. Design Retrospective, stepwise multivariate proportional hazards regression analysis. Setting Johns Hopkins Hospital. Participants All patients who underwent medial SWM resection from 1998 to 2009. Main Outcome Measures Visual function. Results Sixty-five medial SWM resections were performed. After multivariate proportional hazards regression analysis, preoperative visual decline (relative risk [RR] 95% confidence interval [CI]; 13.431 [2.601 to 46.077], p = 0.006), subtotal resection (RR [95% CI]; 3.717 [1.204 to 13.889], p = 0.02), and repeat surgery (RR [95% CI]; 5.681 [1.278 to 19.802], p = 0.03) were found to be independent predictors of visual decline at last follow-up. Tumor recurrence and postoperative radiation therapy trended toward, but did not reach statistical significance. Conclusion These findings advocate for early and aggressive surgical intervention for patients with medial SWMs to maximize the likelihood of subsequent visual preservation. This may provide patients and physicians with prognostic information that may guide medical and surgical therapy for patients with medial SWMs.

Abstract
OBJECTIVE The clinical results of combined surgical-radiosurgical treatment of the spheno-orbital en plaque meningiomas in a consecutive series of 40 patients are presented. The clinical outcome is evaluated in terms of surgical morbidity, tumour control, visual function and cosmetic result. METHODS Forty patients harbouring spheno-orbital en plaque meningiomas were treated. Forty-two surgical procedures were performed through a fronto-temporal craniotomy. The reconstruction of the orbital walls was performed using a titanium mesh. In case of sub-total resection, the patients underwent Gamma-Knife radiosurgery on residual tumour. Visual function was evaluated considering visual acuity tested with a Snellen chart, funduscopy and Goldmann perimetry for visual field defects. Proptosis was quantified on CT scans. RESULTS Total or gross-total tumour resection was achieved in 56.1% of cases. Permanent morbidity was recorded in three patients after surgery. Visual acuity and visual field defect both improved in 66.7% of patients; improvement of proptosis was recorded in 92.7% of cases. Eighteen patients were treated with Gamma-Knife radiosurgery for residual tumour after surgery and four patients for tumour relapse at follow-up. The mean follow-up period was 72.6 months. CONCLUSIONS Surgical treatment of spheno-orbital en plaque meningiomas is safe and effective: a low morbidity rate was recorded and visual function improved in about two-thirds of patients. Reconstruction of the orbital walls with titanium mesh provides for good functional and cosmetic results. In case of superior orbital fissure and cavernous sinus invasion, the combined surgical-radiosurgical treatment allows to minimise surgical morbidity and to achieve tumour control.

Abstract
OBJECT Surgery for giant anterior clinoidal meningiomas that invade vital neurovascular structures surrounding the anterior clinoid process is challenging. The authors present their skull base technique for the treatment of giant anterior clinoidal meningiomas, defined here as globular tumors with a maximum diameter of 5 cm or larger, centered around the anterior clinoid process, which is usually hyperostotic. METHODS Between 2000 and 2010, the authors performed 23 surgeries in 22 patients with giant anterior clinoidal meningiomas. They used a skull base approach with extradural unroofing of the optic canal, extradural clinoidectomy (Dolenc technique), transdural debulking of the tumor, early optic nerve decompression, and early identification and control of key neurovascular structures. RESULTS The mean age at surgery was 53.8 years. The mean tumor diameter was 59.2 mm (range 50-85 mm) with cavernous sinus involvement in 59.1% (13 of 22 patients). The tumor involved the prechiasmatic segment of the optic nerve in all patients, invaded the optic canal in 77.3% (17 of 22 patients), and caused visual impairment in 86.4% (19 of 22 patients). Total resection (Simpson Grade I or II) was achieved in 30.4% of surgeries (7 of 23); subtotal and partial resections were each achieved in 34.8% of surgeries (8 of 23). The main factor precluding total removal was cavernous sinus involvement. There were no deaths. The mean Glasgow Outcome Scale score was 4.8 (median 5) at a mean of 56 months of follow-up. Vision improved in 66.7% (12 of 18 patients) with consecutive neuroophthalmological examinations, was stable in 22.2% (4 of 18), and deteriorated in 11.1% (2 of 18). New deficits in cranial nerve III or IV remained after 8.7% of surgeries (2 of 23). CONCLUSIONS This modified surgical protocol has provided both a good extent of resection and a good neurological and visual outcome in patients with giant anterior clinoidal meningiomas.

Abstract
Background To investigate the natural history and the growth rate of spheno-orbital meningiomas (SOMs). Methods Ninety patients with a diagnosis of SOM were included, and patient charts and imaging were evaluated. In a subset of 32 patients, volumetric studies were performed. Results The median follow-up for the entire group was 4 years (range, 1–15); the mean age was 47.8 (range, 26–93) years; 94% of the patients were female. The most common clinical signs and symptoms were proptosis (93%), visual deterioration (65%), retro-bulbar pain (23%) and diplopia (6%). In 35% of patients in this series, no visual deterioration occurred, and in 30% only mild proptosis was present. The median annual growth rate of the SOMs in the subset of 32 patients was 0.3 cm3/year (range, 0.03–1.8 cm3/year). We assessed a trend for more rapid tumour growth in younger patients and found the initial volume of the tumour (rho = 0.63) and of the soft tissue component (rho = 074) to be significantly related to the growth rate. Conclusion SOMs are slow-growing tumours that cause primarily proptosis and visual deterioration. In a significant number of patients, these tumours cause minimal discomfort and symptomatology. Therefore, in the absence of risk factors, we advocate a “wait and see” policy. For patients with large SOMs or with a large soft tissue component at first visit or with fast growing SOMs (>1cm3/year), a follow-up examination every 6 months is indicated.

Abstract
OBJECTIVE This study defines the indications, results, and limits of lateral orbitotomy coupled with resection of the sphenoid wing for removing lateral sphenoid wing meningiomas with intraorbital extension. METHODS Eighteen patients with lateral sphenoid wing meningiomas and tumor extension into the lateral or superolateral compartments of the orbital cavity were treated by microsurgical lateral orbitotomy and resection of the sphenoid wing without craniotomy. The approach consisted of a linear skin incision along the upper eyelid crease extending to 2 cm from the canthal angle and resection of the lateral orbital rim, lateral orbital wall, and infiltrated sphenoid wing. RESULTS A complete resection (Simpson I), including the infiltrated bone, dura, and periorbita, was obtained in 13 patients (72%); in the other 5 cases (28%), the tumor mass and most infiltrated dura were removed, but the entity of dural resection up to the normal tissue could not be exactly defined (Simpson II). Follow-up ranged from 5 to 17 years (mean 9.7 years). CONCLUSION A select group of lateral sphenoid wing meningiomas with tumor extension in the lateral or superolateral compartments of the orbital cavity may be successfully approached and removed through a lateral orbitotomy with resection of the sphenoid wing and without craniotomy. Cases with tumor extension to the anterior clinoid process and superior orbital fissure and those with extension medial to the axis of the optic nerve require a transcranial approach.

Abstract
BACKGROUND The purpose of this study was to present the findings on growth patterns in a large surgical series of sphenoorbital meningiomas. PATIENTS AND METHODS A retrospective analysis was performed on 77 patients (61 f) harboring sphenoorbital meningiomas, who underwent surgery between 1991 and 2009. The standard surgical approach consisted of pterional craniotomy and extradural resection of any infiltrated bone. The intradural and orbital tumor was resected, with complete reconstruction of the dura while the lateral bone was partially reconstructed. The follow-up period ranged from 6 to 130 months (mean: 57.9 months). RESULTS Total macroscopic resection was achieved in 42 patients. Fifty-eight meningiomas extended to the orbital roof and/or lateral orbital wall, 42 involved the extraconal space, and 11 the intraconal space. Sixty-three tumors involved the superior orbital fissure, 54 the optic canal, and 24 the inferior orbital fissure. Seventeen tumors infiltrated the cavernous sinus and 37 involved the anterior clinoid process. The rate of minor morbidity was 14.3% (slight deficits) and the rate of major morbidity was 4% (significant deficits). Subtotal resections were performed on 35 patients because there was intraorbital tumor (n=8); tumor in the cavernous sinus (n=12); tumor invading the superior orbital fissure (n=12); and tumor of the skull base (n=3). Nine patients underwent postoperative three-dimensional conformal radiotherapy, which resulted in stable tumor volume at follow-up in eight patients. Tumor recurrence was identified in ten patients (12.9%) postoperatively (range of follow-up: 10-47 months). CONCLUSION The goal of surgery is complete tumor removal without morbidity. Exact analysis of tumor growth and possible involvement of pertinent structures are mandatory in planning the procedure.

Abstract
Sphenoorbital meningiomas account for 20% of all orbital tumors treated by neurosurgeons. Proptosis is the main clinical sign but this can be reduced with accurate surgical management. Complete tumor removal is often difficult considering the frequent extensions of the meningioma to the superior orbital fissure, the cavernous sinus, and the periorbita.

Abstract
OBJECTIVE En plaque sphenoid wing meningiomas are complex tumors involving the sphenoid wing, the orbit, and sometimes the cavernous sinus. Complete removal is difficult, so these tumors have high rates of recurrence and postoperative morbidity. The authors report a series of 71 patients with sphenoid wing meningiomas that were managed surgically. METHODS The clinical records of 71 consecutive patients undergoing surgery for sphenoid wing meningiomas at Lariboisière Hospital, Paris, were prospectively collected in a database during a 20-year period and analyzed for presenting symptoms, surgical technique, clinical outcome, and follow-up. RESULTS Among the 71 patients (mean age, 52. 7 years; range, 12-79 years), 62 were females and 9 were males. The most typical symptoms recorded were proptosis in 61 patients (85.9%), visual impairment in 41 patients (57.7%), and oculomotor paresis in 9 patients (12.7%). Complete removal was achieved in 59 patients (83%). At 6 months of follow-up, magnetic resonance imaging scans revealed residual tumor in 12 patients (9 in the cavernous sinus and 3 around the superior orbital fissure). Mean follow-up was 76.8 months (range, 12-168 months). Tumor recurrence was recorded in 3 of 59 patients (5%) with total macroscopic removal. Among the patients with subtotal resection, tumor progression was observed in 3 of 12 patients (25%; 2 patients with grade III and 1 patient with grade IV resection). Mean time to recurrence was 43.3 months (range, 32-53 months). CONCLUSION Surgical management of patients with sphenoid wing meningiomas cannot be uniform; it must be tailored on a case-by-case basis. Successful resection requires extensive intra- and extradural surgery. We recommend optic canal decompression in all patients to ameliorate and/or preserve visual function.

Abstract
OBJECT The authors analyzed the long-term results and radiological aspects of sphenoorbital meningioma (with emphasis on exophthalmos) in a series of 30 patients who underwent resection. METHODS Data obtained in all 30 patients who underwent surgery for typical sphenoorbital meningioma at the authors' institution between June 1994 and September 2005 were analyzed retrospectively. The exophthalmos index (EI) was measured on preoperative MR images and/or CT scans and compared between the early and last follow-up examinations. All patients were women 35-74 years of age (median 51 years). Exophthalmos was the presenting symptom in 28 patients (93%), and was observed on preoperative MR images in all patients. The median duration of symptoms before surgery was 10 months (2-120 months). RESULTS Total resection (Simpson Grade I) was not achieved in these patients because of the impossibility of resecting the dura mater in the superior orbital fissure without causing significant complications. Subtotal resection (Simpson Grade II) was obtained in 90% of patients, and in 3 patients (10%) a portion of the tumor was deliberately left in place because of extensive macroscopic infiltration of the cavernous sinus and/or extraocular muscles (Simpson Grade III). No patient died. Radiological evaluation at a median follow-up of 61 months (range 17-136 months) showed no contrast enhancement in 14 patients (47%), residual contrast enhancement without evolution in 13 (43%), and recurrence (new contrast enhancement) in 3 (10%). The EI was improved at the first radiological follow-up (median 12 months) in 27 patients (90%), and at the last radiological follow-up (median 61 months) in 28 patients (93%). In the interval between the first and final imaging follow-up, the EI improved in only 8 patients (20%), worsened in 15 patients (50%), and showed no variation in 7 patients (30%). CONCLUSIONS Sphenoorbital meningiomas are insidious tumors with slow progression. Even when exophthalmos is not clinically evident, it is always present on preoperative MR imaging. Total resection is not possible due to superior orbital fissure invasion, but subtotal resection (Simpson Grade II) can assure long-term stability due to the nonevolutive nature of most residual tumors. Exophthalmos improves at early radiological follow-up, but may worsen again as time passes.

Abstract
INTRODUCTION En plaque meningioma are a morphological subgroup of meningioma defined by a carpet or sheet-like lesion that infiltrates the dura and sometimes invades the bone. We present an exceptional case due to its localization and evolution. CASE A 41-year-old female patient consulted for progressive swelling of the left frontoparietal region. CT-scan revealed thickening of the cranial medulla, without cerebral lesion. The tumor was removed. Histological analysis confirmed en plaque meningioma which recurred 7 years after. DISCUSSION En plaque meningioma are a rare subtype of meningioma which rarely affects the skull vault. Relapse is frequent.

Abstract
OBJECTIVE Spheno-orbital meningiomas represent a delicate subtype of intracranial meningiomas involving the sphenoid wing, orbit and important neurovascular structures such as cavernous sinus, carotid artery or optic nerve. Insidious and aggressive dural, bone and orbital involvement contains several defiances to adequate resection, which provides high rates of recurrence. METHODS This retrospective case analysis consisted of 30 patients, who were surgically treated for spheno-orbital meningiomas performing a fronto-pterional approach by or under the supervision of the senior author (J. Meixensberger) between May 2001 and February 2006. There were 22 woman and eight men with a mean age of 54.4 years. The follow-up period ranged from 3 to 75 months (mean: 33.7 months). RESULTS The majority of patients presented with a clinical triad of visual impairment (74%), progressive proptosis (55%) and visual field defects (40%). Total microscopic tumor resection was achieved in ten patients (33%). Visual acuity improved in 65% of the patients, and 40% of these returned to normal vision. Pre-existing cranial nerve deficits remained unchanged in the majority of patients (88%) and improved in 12%. Temporary new cranial nerve deficits occurred in three patients. The rate of permanent non-visual morbidity was 10% (three of 30 patients). Eight patients (27%) received post-operative radiotherapy with an overall tumor growth control rate of 63%. The overall recurrence rate was 27% (eight of 30 patients). CONCLUSION Sufficient tumor control can be achieved with minimal morbidity and satisfying functional results.
