مصطلحات موضوعية: NEUROGENIC bladder, LUMBOSACRAL region, NATURAL history, SYMPTOMS, CONUS, SURGICAL & topographical anatomy

مستخلص: Objective: Conus region lumbosacral lipomas (LSLs) are highly heterogeneous in their morphology, clinical presentation, and outcome, with an incompletely understood natural history and often treacherous surgical anatomy. This systematic review aims to critically evaluate and assess the strength of the current LSL evidence base to guide management strategies. Methods: According to a systematic review following PRISMA guidelines, a search was conducted using the key term "lumbosacral lipoma" across MEDLINE (OVID), Embase, Cochrane Library, and PubMed databases from January 1951 to April 2021. All studies containing ten or more paediatric conus lipomas were included. Data heterogeneity and bias were assessed. Results: A total of 13 studies were included, containing 913 LSLs (predominantly transitional type—58.5%). Two-thirds (67.5%) of all patients (treated and non-treated) remained clinically stable and 17.6% deteriorated. Neuropathic bladder was present in 8.6% at final follow-up. Of patients managed surgically, near-total resection vs. subtotal resection deterioration-free survival rates were 77.2–98.4% and 10–67% respectively. 4.5% (0.0–27.3%) required re-do untethering surgery. Outcomes varied according to lipoma type. Most publications contained heterogeneous populations and used variable terminology. There was a lack of consistency in reported outcomes. Conclusion: Amongst published series, there is wide variability in patient factors such as lipoma type, patient age, and methods of (particularly urological) assessment. Currently, there is insufficient evidence base upon which to make clear recommendations for the management of children with LSL. There is an imperative for neurosurgeons, neuroradiologists, and urologists to collaborate to better standardise the terminology, assessment tools, and surgical interventions for this challenging group of conditions.

مستخلص: Purpose: Pediatric intraventricular tumors of the third ventricle are among the most difficult-to-treat brain tumors. Recently, endonasal endoscopic surgery for suprasellar, third ventricle, and median clivus lesions has become the common procedure, and its indications are expanding to pediatric cases. We describe our strategy for endonasal endoscopic surgery for pediatric third ventricle tumors. Method: We report on surgical anatomies and our surgical procedures in detail, including case presentations. Result: Endoscopic endonasal surgery has the advantage of providing a wider view of the tumor site, hypothalamus, optic chiasm, and other critical structures. Good indications for the endoscopic endonasal approach for intra-third ventricular tumors are those arising from the floor of the third ventricle. In particular, craniopharyngioma, a typical pediatric suprasellar tumor, sometimes extends into the third ventricle, causing great operative difficulty. However, aggressive removal for long-term control while preserving memory and visual function is important. We perform surgery with a strategy of radically removing tumors without causing damage to visual or brain function, and we adopt the "4-hands technique by two neurosurgeons" in full endoscopic surgery to remove tumors safely and aggressively. Conclusion: We describe our strategy for endonasal endoscopic surgery for pediatric third ventricle tumors, especially those extending from the suprasellar region into the third ventricle, and present a representative case.

مصطلحات موضوعية: OPEN source software, PATIENTS' families, CONJOINED twins, SURGICAL & topographical anatomy, TWINS

مستخلص: Background: Craniopagus twins represent a rare and complex congenital malformation characterized by conjoined twins fused at the cranium. Craniopagus is challenging for patients' families and surgeons, and accurate confirmation of the extent of cranial fusion is a complex process. Most information regarding the surgical anatomy of this rare condition is obtained through analysis of ultrasonographic, magnetic resonance, or computed tomographic images. A multidisciplinary team plays a key role in obtaining such information and in parental counseling and coordination of various complex processes for optimal postnatal care of these twins. The extent of fusion is usually determined based on conventional clinical methods, such as imaging studies. Methods: Imaging software is being used in recent times to create three-dimensional reconstruction images and for virtual navigation to investigate the skulls and brains of craniopagus twins. However, the acquisition and maintenance costs of such sophisticated medical software may be unaffordable for medical centers in developing countries. To overcome this limitation, we investigated the role of open or free source software for accurate determination of complex malformations of the skull and brain of craniopagus twins.

مصطلحات موضوعية: SKULL base, ANATOMICAL variation, SURGICAL & topographical anatomy, VEINS, SKULL surgery, COMPUTED tomography

مستخلص: The condylar canal and its associated emissary vein serve as vital landmarks during surgical interventions involving skull base surgery. The condylar canal serves to function as a bridge of communication from the intracranial to extracranial space. Variations of the condylar canal are extremely prevalent and can present as either bilateral, unilateral, or completely absent. Anatomical variations of the condylar canal pose as a potential risk to surgeons and radiologist during diagnosis as it could be misinterpreted for a glomus jugular tumor and require surgical intervention when one is not needed. Few literature reviews have articulated the condylar canal and its associated emissary vein through extensive imaging. This present paper aims to further the knowledge of anatomical variations and surgical anatomy involving the condylar canal through high-quality computed tomography (CT) images with cadaveric and dry bone specimens that have been injected with latex to highlight emissary veins arising from the condylar canal.

مستخلص: The objective of this study is to recognize the available endoscopic routes during approaches to the suprasellar region and the surgical endoscopic anatomy of the related neurovascular structures. Extended endoscopic endonasal approach to the suprasellar region (EEASR) through the planum sphenoidale was performed in five fresh adult cadavers. The anatomic characteristics of the suprasellar parachiasmatic cisterns were studied and documented following the resection of the planum sphenoidale and opening the dura to expose the anterior incisural space. Two separate surgical corridors could be used during EEASR: one above and the other below the chiasm. The suprachiasmatic route exposed the gyrus recti, interhemispheric fissure, anterior cerebral artery complex, the lamina terminalis, and through this structure the anterior recess of the third ventricle. The subchiasmatic route exposed the pituitary stalk, superior hypophyseal artery, supraclinoidal internal carotid artery, origin of the ophthalmic artery, anterior choroidal artery, posterior communicating artery, uncus, optic tract, basilar artery and its bifurcation, pons, posterior cerebral artery, superior cerebellar artery, and oculomotor nerve. The EEASR, a minimally invasive route to suprasellar parachiasmatic area, provided wide exposure of the basal cisterns. The surgical areas that were accessed through the subchiasmatic corridor could be divided into a medial part that included the interpeduncular and prepontine cisterns and a lateral part that contained carotid and sylvian cisterns superiorly and the crural and ambient cisterns inferiorly.

مستخلص: The goal of the present study was to develop a three-dimensional (3D) geometrical model based on pre- and post-dissection Digital Imaging and Communication in Medicine (DICOM) images of both transcranial and endonasal skull base approaches. Such model was structured for either teaching surgical anatomy and to evaluate the amount of bone removal over the skull base surface through a 3D digital perspective. Twenty-five human cadaveric heads were dissected at the Laboratory of Surgical NeuroAnatomy (LSNA) of the University of Barcelona (Spain) between 2007 and 2009. Before and after each dissection, a computed tomography-scan (CT-scan) was obtained in order to create a 3D geometrical model of the same approach performed in the dissection laboratory. The model protocol was designed as follows: (1) preoperative CT-scan of the specimens; (2) creation of a computer-generated 3D model of the specimen using specific imaging software for visualization and manipulation of biomedical data; (3) dissection of the specimens; (4) development of a 3D CT-based model of the approach as a result of the overlapping of the DICOM data of the specimens before and after the dissection. The fusion of the pre- and post-dissection 3D models allowed evaluation of the amount of bone removal over the skull base surface. Measurements of the bony landmarks as well as the visual feedback of the drilled bone over the skull base provided by our 3D model gives the opportunity to improve the tailoring of each approach to the different skull base areas.
