Eagle Syndrome: Efficacies Of Medical And Surgical Treatments, Kirklin Mitchell

Capstone Showcase

Eagle Syndrome is a rare syndrome caused by elongation of the styloid process of the temporal bone or calcification of the stylohyoid ligament occurring in a very small percentage of the population that can cause a wide range of common symptoms, leading to it being often misdiagnosed. While there are no set standards for treating Eagle Syndrome, both pharmaceutical and surgical options exist. Pharmaceutical options are often ineffective in long term treatment so surgery is usually required for full symptom resolution. Transoral and Transcervical surgeries have similar efficacies but each come with important drawbacks when considering which type of surgery …

The Scientific Divulgation In Neurosurgery., Rodrigo Ramos-Zuñiga, Sergio Manuel Ibarra-Navarro

Archives of Neurosurgery

The communication of scientific findings in a young discipline in the evolution of knowledge about the human nervous system, has had a consistent and significant advance. This interdisciplinary and multidisciplinary vision has been a fundamental educational axis in the development of neurosurgery in terms of innovation, scientific progress, technological development and quality of patient care. It is therefore essential that scientific writing and communication channels continue to preserve these quality standards, to validate without bias and with certainty, the value and strength of the advances of neurosurgery as a science.

L5-S1 Collapsed Space Is Not A Contraindication For Elif. Technical Note And Preliminary Clinical Results, Iris Tatiana Montes González, Sergio Soriano Solis, Manuel Eduardo Soto García, Manuel Rodríguez García, Gerson Reyes Rodríguez., Víctor David López García, José Antonio Soriano Sánchez

Archives of Neurosurgery

INTRODUCTION: Extraforaminal lumbar interbody fusion (ELIF) avoids vascular, neural, and genitourinary risks of anterior and lateral techniques. However, many authors consider ELIF to be contraindicated in L5-S1, especially in the case of a collapsed space. Therefore, we aim to provide a technical note for ELIF in the context of an L5-S1 collapsed space and present our experience and the postoperative clinical results of our patients. MATERIALS AND METHODS: We collected data from the records of patients with ELIF L5-S1 level collapsed between March 2020 to June 2021, using for this study sex, age, clinical symptoms, diagnosis, L5-S1 height space, EVA, …

Microvascular Decompression For Hemifacial Spasm: Surgical Technical Nuances And Results After 300 Microvascular Decompression Surgeries, Rogelio Revuelta Gutiérrez, Miguel Vega-Arroyo, Olivia L. Vales-Hidalgo, Cynthia E. López-Rafael, Jesús Martínez-Manrique, Sergio Moreno Jiménez

Archives of Neurosurgery

Introduction: Hemifacial spasm (HFS) is characterized by the involuntary, paroxysmal, painless, and progressive spasmodic contractions of facial muscles innervated by the ipsilateral seventh cranial nerve. To date, neuroimaging studies (Computed Tomography scan [CT] and Magnetic Resonance Imaging [MRI]) are unable to establish the diagnosis. HFS medical treatment with antiepileptic drugs, and Botulinum toxin application are temporarily effective, however, both have shown side effects and lesser cost-effective results. Currently, surgical Micro Vascular Decompression (MVD) for HFS has the highest curative rates and lower operative morbidity. We analyze the demographics, clinical manifestations, outcomes, and complications that to our knowledge, is the largest …

Aneurysmal Subarachnoid Hemorrhage And Acute Subdural Hematoma, Neurosurgical And Endovascular Rescue. Case Report., José Omar Santellan Resident, José Ramón Aguilar Dr., Abraham Ibarra Dr., Ulises García Dr.

Archives of Neurosurgery

Introduction: Acute subdural hemorrhage (aSDH) in association with aneurismal subarachnoid hemorrhage (SAH) is a severe disease with an incidence of 0.5% to 7.9% of all SAH. Due to the rarity of aneurysmal aSDH, it remains difficult to define a comprehensive management protocol. In this case review, following the CARE guidelines, we show the hybrid management of this pathology to know the importance of using different types of neurosurgical treatments in case of two severe diseases in critical patients.

We present two patients who developed sudden onset cephalea and neurological impairment secondary to aneurysmal subarachnoid hemorrhage associated with acute subdural hematoma. …

Passive Functional Mapping Using Infrared Thermography In Epilepsy Awake Surgery: Case Report, Enrique De Font-Réaulx, Javier Terrazo-Lluch, Paul Shkurovich-Bialik, Miguel Ángel Collado-Corona, Ernesto Ramírez-Navarrete, Luis Díaz-López Md, Alma Rosa Martínez-Rosas Msc, Adalberto González-Astiazarán

Archives of Neurosurgery

Background: Active Functional Mapping (AFM) is the gold standard method for localizing cortical and subcortical brain functional areas and tracts. By definition, it requires direct application of controlled electrical stimuli under established protocols. Nevertheless, it entails inherent risks, such as causing intraoperative seizures. On the other hand, Passive Functional Mapping (PFM) doesn´t require electrical stimulation of the nervous system. PFM is based on the knowledge that brain metabolism generates different electromagnetic radiation patterns depending on its metabolism, that are invisible to the human eye, but infrared thermographic cameras can show those changes related to brain activity without the use of …

The Many Worlds Of Neurosurgery And The Labyrinth Of Borges, Juan F. Villalonga, Giulia Guizzardi, Domenico Solari

Archives of Neurosurgery

Nowadays, an apprentice of neurosurgery has to complete long and different pathways of education.The encounter between the schools of Napoli and Tucuman, make us identify a common strategy of neurosurgical education. In attempt of defining the philosophy behind it we attempt a comparison in between the life and training of a modern neurosurgeon and the character of a tale of Borges (i.e. Ts'ui Pên). As neurosurgeons of the 21st century we must be like the inextricable Ts'ui Pên.

An Unusual Case Of A Giant Intradiploic Epidermoid Cyst Removed Using A Combined Supra-Infratentorial Retromastoid Approach., César Adán Almendárez-Sánchez, Saúl Solorio-Pineda, Abrahan Alfonso Tafur-Grandett, Miguel Ángel Ramírez-Sosa Dr., Gabriel Arturo Ramos Martínez, Leonardo Álvarez-Vázquez

Archives of Neurosurgery

Background: Epidermoid cysts (EC) are relatively rare congenital lesions. They arise from ectodermal debris during aberrant closure of the neural tube, are benign, and of slow growth. They are found predominantly in the cistern of the cerebellopontine angle, most are intradural, and very rarely, there is underlying compression of the venous sinuses, leading to benign intracranial hypertension.

Case description: We present the case of a patient diagnosed with a giant extradural, intradiploic EC with compression of the left transverse sinus and its successful management by using ultrasonic aspiration, performing a combined supra-infratentorial retromastoid approach with occipitotemporal craniotomy, without subsequent …

Stereotactic Radiosurgery For Pituitary Adenomas: A Review Of Literature, Kaynat Siddiqui, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

Stereotactic radiosurgery (SRS) is a choice of treatment for pituitary adenomas (PA), particularly for residual or recurrent disease, apart from surgery. It has a progression free survival and endocrine remission rate comparable to surgery, with fewer side effects, making it an ideal tool for dealing with PA. In this review, we have discussed the role of SRS for primary as well as post-operative residual/ recurrent PA, and have assessed its safety and outcomes.

Section of Neurology

Background: Early intensive blood pressure (BP) lowering remains the most promising treatment for acute intracerebral hemorrhage (ICH), despite discordant results between clinical trials and potential variation in the treatment effects by approach to control BP. As the third in a series of clinical trials on this topic, the INTEnsive care bundle with blood pressure Reduction in Acute Cerebral hemorrhage Trial (INTERACT3) aims to determine the effectiveness of a goal-directed care bundle protocol of early physiological control (intensive BP lowering, glycemic control, and pyrexia treatment) and reversal of anticoagulation, in acute ICH.
Methods: INTERACT3 is a pragmatic, international, multicenter, stepped-wedge (4 …

Can Activated Titanium Interbody Cages Accelerate Or Enhance Spinal Fusion? A Review Of The Literature And A Design For Clinical Trials, Nathaniel Toop, Connor Gifford, Rouzbeh Motiei-Langroudi, Arghavan Farzadi, Daniel Boulter, Reza Forghani, H. Francis Farhadi

Neurosurgery Faculty Publications

While spinal interbody cage options have proliferated in the past decade, relatively little work has been done to explore the comparative potential of biomaterial technologies in promoting stable fusion. Innovations such as micro-etching and nano-architectural designs have shown purported benefits in in vitro studies, but lack clinical data describing their optimal implementation. Here, we critically assess the pre-clinical data supportive of various commercially available interbody cage biomaterial, topographical, and structural designs. We describe in detail the osteointegrative and osteoconductive benefits conferred by these modifications with a focus on polyetheretherketone (PEEK) and titanium (Ti) interbody implants. Further, we describe the rationale …

At the time of this writing, the coronavirus disease 2019 pandemic continues to be a global threat, disrupting usual processes, and protocols for delivering health care around the globe. There have been significant regional and national differences in the scope and timing of these disruptions. Many hospitals were forced to temporarily halt elective neurointerventional procedures with the first wave of the pandemic in the spring of 2020, in order to prioritize allocation of resources for acutely ill patients and also to minimize coronavirus disease 2019 transmission risks to non-acute patients, their families, and health care workers. This temporary moratorium on …

Nanomedicine In The Treatment Of Glioblastoma, Syeda Kubra Kishwar Jafri, Syed Sarmad Bukhari, Muhammad Shahzad Shamim

Section of Neurosurgery

The current standard of care in glioblastoma management is surgery followed by chemotherapy and radiotherapy. Temozolomide is an alkylating agent most commonly used with a few other second line options. The efficacy of systemic chemotherapy in brain malignancies is limited due to the nature of the blood-brain barrier. Nanomedicine offers one avenue of improving drug delivery to these tumours in a more focussed and effective way in higher doses than currently possible, while simultaneously reducing systemic toxicity.

Department of Neurology Faculty Papers

To see whether acute intraoperative recordings using stereo EEG (SEEG) electrodes can replace prolonged interictal intracranial EEG (iEEG) recording, making the process more efficient and safer, 10 min of iEEG were recorded following electrode implantation in 16 anesthetized patients, and 1–2 days later during non-rapid eye movement (REM) sleep. Ripples on oscillations (RonO, 80–250 Hz), ripples on spikes (RonS), sharp-spikes, fast RonO (fRonO, 250–600 Hz), and fast RonS (fRonS) were semi-automatically detected. HFO power and frequency were compared between the conditions using a generalized linear mixed-effects model. HFO rates were compared using a two-way repeated measures ANOVA with anesthesia type …
