Abstract Objective The endoscopic endonasal approach (EEA), has become the preferred alternative to traditional open and transoral approaches ventral craniovertebral junction (CVJ) region. However, preoperative prediction of limitations caudal reach remains challenging. This cadaveric study aimed quantify CVJ area exposure access afforded by EEA, evaluate accuracy previously described radiographic anthropometric lines, identify lowest limit EEA corridor. Methods Endoscopic dissections were...
BACKGROUND AND OBJECTIVES: The endoscopic endonasal transpterygoid approach (TPA), minimally invasive compared with the sublabial transmaxillary and transcranial approaches, still accounts for morbidity in benign lateral recess of sphenoid sinus (LRSS) pathologies. Others have suggested an alternative route to LRSS, contralateral medial transorbital (cMTO). However, no quantitative evidence exists support clinical application this approach. This cadaveric study, a controlled laboratory...
OBJECTIVE Minimally invasive endoscopic endonasal multiport approaches create additional visualization angles to treat skull base pathologies. The sublabial contralateral transmaxillary (CTM) approach and superior eyelid lateral transorbital approach, frequently used nowadays, have been referred as the "third port" when alongside (EEA). precaruncular medial (cMTO) corridor, on other hand, is an underrecognized but unique port that has repair CSF rhinorrhea originating from sphenoid sinus...
OBJECTIVE Accessing the petrous apex (PA) via an endoscopic endonasal approach (EEA) is challenging due to its posterior and lateral anatomical relationship with paraclival carotid artery. Typically, EEA requires mobilization or compression of vessel use angled-lens endoscopes instruments. A sublabial contralateral transmaxillary (CTM) corridor has been used overcome these challenges. Still, it extensive osteo-meatal disruption drilling medial pterygoid process, which risks vidian nerve...
Objectives: While the endoscopic endonasal approach (EEA) has emerged as a preferred alternative to traditional transoral access for craniovertebral junction (CVJ) surgery, its limited inferior reach beyond C1 level remains significant challenge. This study investigates effectiveness of using contralateral nasofrontal trephination (CNT) or posterior palatectomy (PP) enhance caudal CVJ region. Design: A quantitative cadaveric study. Setting: Cadaver dissection laboratory. Participants:...
BACKGROUND AND OBJECTIVES: The endoscopic endonasal approach (EEA) serves as the primary minimally invasive route to ventral craniovertebral junction (CVJ). However, anatomic constraints limit its caudal reach. Multiport approaches may complement a standard EEA providing additional This study evaluates EEA's limitations in accessing CVJ and examines how contralateral nasofrontal trephination (CNT) port overcome these constraints. METHODS: Thirty-two cadaveric specimens underwent CNT...
Expanded endonasal approaches (EEAs) have proven safe and effective in treating select petrous apex (PA) pathologies. Angled endoscopes instruments expanded indications for such approaches; however, the complex neurovascular anatomy surrounding region remains a significant challenge. This study evaluates feasibility, anatomic aspects, limitations of contralateral nasofrontal trephination (CNT) route as complementary corridor improving access to PA.
Abstract Background Primary central nervous system melanoma is an extremely rare entity and even rarer in children adolescents as compared to adults. It often difficult consider a diagnosis of intracranial pre-operatively without any clinical evidence neurocutaneous melanosis. Case presentation Herein, case primary the brain reported 17-year-old female who presented with headache, vomiting, focal neurological deficit form left-sided facial palsy limb weakness. A contrast-enhanced computed...
Rathke's cleft cysts (RCCs) exhibit variable growth patterns, thus posing a challenge in predicting progression. While some RCCs may not cause symptoms, others can insidiously pituitary dysfunction, which is often irreversible, even following surgery. Hence, it crucial to identify asymptomatic that grow rapidly and pose higher risk of causing endocrinologic dysfunction. This enables timely surgical intervention prevent permanent damage. Our study examines the rate RCCs, identifies factors...
OBJECTIVE Different techniques of performing image-guided neurosurgery exist, namely, neuronavigation systems, intraoperative ultrasound, and MRI, each with its limitations. Except for other methods are expensive. Three-dimensional virtual reconstruction surgical simulation using 3D volume rendering (VR) is an economical excellent technique preoperative planning neurosurgery. In this article, the authors discuss several nuances VR that have not yet been described. METHODS The included 6...
Pineal region tumors often present with hydrocephalus. Endoscopic third ventriculostomy (ETV) and simultaneous tumor biopsy remain a minimally invasive procedure offering both diagnostic therapeutic advantages in the management of these tumors. However, different operative techniques have been described literature.The aim is to study ETV success rate, rate biopsy, complications, follow-up patients pineal managed using single burr hole technique.The was performed by retrospectively reviewing...
We report the case of a 30-year-old female with Sylvian fissure, white epidermoid which was radiologically looking like dermoid cyst. The presented headache no neurological deficits. On radiology, lesion in T1 hyperintense, T2 hypointense, and minimal diffusion restriction medially. Hence preoperative impression cyst made, quite uncommon location. Intraoperatively, classical pearly-white flaky appearance seen confirmed histopathologically. White epidermoids appearing so because high protein...
Insular high-grade gliomas are uncommon and constitute approximately 10% of all intracranial gliomas. Several publications in the recent years have thrown substantial light understanding insular low-grade However, there is a paucity information concerning spectrum lesions affecting insula, mode presentation vis-à-vis gliomas, survival rates to modern therapy.We aim highlight various clinical patterns, histo-pathological patients with lesions. Also, we explore factors that govern favourable...
There is an acute shortage of neurosurgeons and spine surgeons especially in rural areas low- middle-income countries including India. Patients surgery need to travel long distances for follow-up at tertiary care hospitals. This study was done evaluate role success rate telemedicine after based on patients' diagnosis demographic features identify barriers successful consultations.
Background Insular gliomas are unique, challenging and evoke a lot of interest amongst neurosurgeons. Publications on insular glioma generally focus the surgical intricacies extent resection pertaining to low-grade gliomas. glioblastomas (iGBM) have not been analysed separately before.Methods Histologically proven WHO grade IV involving insula over 9-year period were studied. Their clinical presentation, radiological features, findings survival outcomes assessed. Statistical methods used...
