Methods: Between Apr. 2014 and Mar.

Bone Sandwich Closure Technique for Posterior Fossa Craniectomy.

 Surgery of posterior fossa including cerebellopontine (CP) angle involves either craniectomy or craniotomy. While there has been precedence of craniotomy in recent practice, the preferred access in resource-strapped centers still remains been craniectomy. Although the latter offers an excellent exposure, it is believed to carry increased risk of postoperative pseudomeningocoele and cerebrospinal fluid (CSF) leak compared with craniotomy.

A system of radiological criteria for grading and prognosticating temporal lobe contusions.

Introduction: Temporal contusions are common in patients with head injuries and require close monitoring due to the propensity of these patients to deteriorate rapidly and fatally. This study attempts to introduce a radiological grading system for temporal lobe contusions and analyse its prognostic value so as to better identify patients at risk of deterioration.

Methods: The study was conducted as a cross-sectional observational study from April 2011-March 2017 on 42 patients with temporal lobe contusion.

Forty years of clinical excellence at the Dr A Lakshmipathi Neurosurgical Centre and Post-Graduate Institute of Neurological Surgery, Voluntary Health Services (VHS) Hospital.

It has been a leader and trendsetter among the private academic neurosurgical training institutions, and because of its unique legacy, has influenced the progress of Neurosurgery in India. The center was the second neurosurgical Institute to be created by Prof.

Mindbomb Homolog-1 Index in the Prognosis of High-Grade Glioma and Its Clinicopathological Correlation.

Introduction: Gliomas are the most common brain tumors in adults originating from the glial cells. Glioblastoma multiforme is the most malignant and frequent among all gliomas. In recent years, the antibody Mindbomb Homolog-1 (MIB-1) has evolved as a measure of the proliferative nature of the glial tumors.

Delayed Pneumoventricle Following Endonasal Cerebrospinal Fluid Rhinorrhea Repair with Thecoperitoneal Shunt.

Pneumocephalus and pneumoventricle are well-documented in neurosurgical practice. Although both are common posttraumatic sequelae, iatrogenic causes are also well recognized. Iatrogenic causes may be seen after intracranial surgical procedures or cerebrospinal fluid (CSF) diversion procedures.

Modified high cervical approach for C3-4 anterior pathology in difficult neck patients.

Introduction: The anterior approach to cervical pathologies is a time-tested versatile approach. It is, however, associated with a number of pharyngo-tracheo-laryngeal complications (PTL complications) such as dysphonia, dysphagia, and aspiration, more commonly in high cervical C3-4 inclusive pathologies and even more so in patients with "difficult neck." The modified high cervical approach was devised and employed to address these issues at our institution.

Case series of trigonal meningiomas.

Background: Trigonal meningiomas have unique clinical presentation, unlike those in other areas of brain. Situated deep in the brain, the surgical nuances of this tumour are distinctive. We present our experience with this tumour including a discussion of surgical corridors that may be employed.

Surgical anatomy of lateral recess in paediatric auditory brainstem implant patients and its clinical correlates including grades of flocculus.

Introduction: Auditory brainstem implant (ABI), a standard technique in treatment of profound sensorineural hearing loss in patients with neurofibromatosis 2, is now being increasingly employed in children with congenital bilateral sensorineural hearing loss, as in Michele's deformity. A detailed knowledge of the relevant surgical anatomy of the lateral recess and its anatomical landmarks including the flocculus, the choroid plexus and the root entry zones of facial-vestibulocochlear and glossopharyngeal-vagus nerve complexes and their anatomical variants is mandatory, as it is the conduit for electrode array placement. The placement of electrode may be eased or impeded by these variations.

Quad Fever: Treatment through Lowering of Ambient Temperature.

Hyperpyrexia is a rare and at times fatal condition seen in an Intensive Care Unit setup. We encountered a case of a 65-year-old patient with road traffic accident presenting with dorsal spine fracture at D level. He underwent decompression and fusion for the same.

Concurrent Multilevel Spinal Intra-medullary with Extensive Intracranial Tuberculomas: A Rare Case Report.

Disseminated tuberculomas in the brain and spinal cord are rare. To the best of our knowledge, only nine cases of spinal intra-medullary tuberculomas with cranial involvement have been reported till date. However, involvement of all levels in the spinal cord, brain stem with pan lobar involvement of the cerebrum and cerebellum has not been reported so far.

Does cerebellar flocculus size affect subjective outcomes in pediatric auditory brainstem implantation.

Objectives: The objectives of study was to 1) Describe relevant surgical anatomy in defining and accessing the lateral recess for placement of electrode, 2) Propose a working classification for grades of Flocculus; 3) To determine if different grades of cerebellar flocculus effects placement of ABI electrode and subjective outcomes in implantees.

Methods: Our study was a prospective study, and comprised of cohort of 12 patients who underwent ABI surgery via retrosigmoid approach between 1 Jan 2012 to 31 Dec 2014. All children with congenital profound sensorineural hearing loss with either absent cochlea or cochlear nerve were included in the study.

Postoperative Central Nervous System Infection After Neurosurgery in a Modernized, Resource-Limited Tertiary Neurosurgical Center in South Asia.

Objective: Postoperative central nervous system infections (PCNSIs) are rare but serious complications after neurosurgery. The purpose of this study was to examine the prevalence and causative pathogens of PCNSIs at a modernized, resource-limited neurosurgical center in South Asia.

Methods: A retrospective analysis was conducted of the medical records of all 363 neurosurgical cases performed between June 1, 2012, and June 30, 2013, at a neurosurgical center in South Asia.

An observational study on outcome of hemispherotomy in children with refractory epilepsy.

Introduction: The current study aimed to evaluate the clinical characteristics and outcome of hemispherotomy in children with refractory hemispherical epilepsy.

Methods: Retrospective analysis of data in twenty one children aged ≤12 years who underwent hemispherotomy and had at least two years post surgery follow-up was performed. Sixteen children underwent Delalande's vertical para-sagittal hemispherotomy (VPH), while lateral peri-insular functional hemispherotomy was performed in the rest.

Spinal accessory nerve schwannomas masquerading as a fourth ventricular lesion.

Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8(th) cranial nerve (the vestibulo-cochlear nerve) followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare.

Cervical Subependymoma: A rare case report with possible histogenesis.

Subependymomas are extremely rare lesions of the spinal cord. Only 33 cases including ours have been reported in the cervical cord. These are typically benign slow growing tumors occurring eccentrically within the cord, producing minimal neurological deficits.

Crescent posterior fossa durotomy for occipito-marginal venous sinus preservation: a pilot study.

Purpose: The standard approach of midline suboccipital craniectomy entails sacrifice of the Occipito-marginal sinus. We have attempted to preserve this venous channel by using a durotomy technique which preserves this system. In a pilot study initiative, two groups of patients using this technique versus the standard approach, were compared in terms of per and post operative benefits, morbidity and complications.

Neuroplasticity in hemispheric syndrome: an interesting case report.

Functional hemispherectomy is an accepted treatment in hemispherical intractable epilepsy syndromes. We report a patient who had functional hemispherectomy for intractable seizures secondary to right hemispheric cortical dysplasia. Preoperatively, the patient had mild left hemiparesis and functional magnetic resonance imaging (fMRI) showed bilateral motor function lateralization to normal left hemisphere.
