Brainstem and Spinal Arachnoiditis Ossificans Associated With Neurocysticercosis: A Case Report.

Arachnoiditis ossificans (AO), a very rare entity that can cause severe neurological deficit, is associated with an inflammatory response and compressive effect on the spinal cord. A 65-year-old woman with diagnosis of arachnoiditis ossificans, who had a past medical history of neurocysticercosis diagnosed eight years before the actual onset that was accompanied by obstructive hydrocephalus and required bilateral ventriculoperitoneal shunts, presented with lower limb paresis. The spinal CT reported large calcified subdural spinal plaques.

Unilateral approach for bilateral clipping of posterior communicating artery aneurysms in a hybrid operating room: A technical note.

Bilateral posterior communicating (pComm) artery aneurysms represent only 2% of mirror intracranial aneurysms. Usually, these are surgically approached through bilateral craniotomies for clipping. We present the case of a 50-year-old female presenting with headache and horizontal diplopia.

Glossopharyngeal and vagoglossopharyngeal neuralgia: Long-term surgical outcomes in a single institution.

The objective of the study is to determine the correlation between radiological and clinical outcomes in patients surgically treated by ACDF with 2 different stand-alone cervical cages.

Methods: Clinical outcomes were evaluated using visual analog scale (VAS), Neck Disability Index (NDI), Nurick Scale, and Japanese Orthopedic Association score for myelopathy.

Minimally Invasive Surgical Technique for the Management of Giant Dumbbell Spinal Schwannoma.

Background:  Completely extradural spinal schwannomas have a unique morphology (dumbbell tumors) with an intra- and extraspinal component. When they compromise two contiguous vertebral bodies or have an extraspinal extension >2.5 cm, they are classified as giant spinal schwannomas.

Endonasal Endoscopic and Hybrid Surgery Techniques for Blunt Trauma Fractures of the Skull Base With Cerebrospinal Fluid Leaks.

Cerebrospinal fluid (CSF) leakage caused by skull base fracture represents high risks of bacterial meningitis, and a rate of mortality of 8.9%. Endoscopic endonasal repair of CSF leaks is quite safe and effective procedure with high rates of success.

Endoscopic endonasal lateral transellar approach for growth hormone-secreting adenomas with cavernous sinus invasion: Technical note and surgical results.

Background: Cavernous sinus (CS) invasion is found in 15-20% of pituitary adenomas; it represents a poor prognosis factor and a surgical challenge even in experienced pituitary centers. We present our experience and technical note description for surgical management of pituitary adenomas with CS invasion in acromegaly by the transsellar lateral approach with an endoscopic endonasal transsphenoidal route.

Method: prospective case series of patients who underwent endoscopic endonasal surgery for Growing Hormone (GH) producing adenomas with CS invasion treated at the Neurosurgery departments of National Institute of Neurology and Neurosurgery in Mexico City, and of Toluca Medical Center of Social Security Institute of the State of Mexico and Provinces between January 2014 and March 2019.

Dynamic Fixation Techniques for the Prevention of Adjacent Segment Disease: A Retrospective Controlled Study.

Study Design: Retrospective, controlled study.

Purpose: Dynamic fixation (topping-off technique) adjacent to a transforaminal lumbar interbody fusion (TLIF) level was developed to reduce the risk of adjacent segment disease (ASDi). This study was designed to compare the clinical and radiological outcomes between patients who underwent circumferential lumbar fusion (CLF) without the topping-off technique, CLF with dynamic rod constructs (DRC), and CLF with interspinous device (ISD).

Endoscopic endonasal lateral transellar approach for growth hormone-secreting adenomas with cavernous sinus invasion: Technical note and surgical results.

Background: Cavernous sinus (CS) invasion is found in 15-20% of pituitary adenomas; it represents a poor prognosis factor and a surgical challenge even in experienced pituitary centers. We present our experience and technical note description for surgical management of pituitary adenomas with CS invasion in acromegaly by the transsellar lateral approach with an endoscopic endonasal transsphenoidal route.

Locking Stand-Alone Cage Constructs for the Treatment of Cervical Spine Degenerative Disease.

Study Design: Prospective case series study.

Purpose: Description of the outcome of stand-alone cervical cages for single and multilevel cervical degenerative spine disease.

Overview Of Literature: The aim of anterior cervical discectomy and fusion (ACDF) for cervical spine disease is to improve patient symptoms and spine stability and restore lordosis.

Hybrid Technique for Cranial Defect Reconstruction: Surgical Results over a 10-Year Period in a Single Institution.

Decompressive craniectomy is an urgent procedure that is increasingly used for treatment of intracranial hypertension. After recovery, reconstruction of the cranial defect is necessary. Cranioplasty is an elective procedure with a high potential for morbidity if care is not taken on different surgical factors such as the material used as the cranial flap.

Intradural spinal tumors: 10 - years surgical experience in a single institution.

Objectives: The aim of the study is to present the therapeutic results of intradural tumor management over a 10 years period in a single institution.

All patients were provided with information about the procedure and signed informed consent and institutional board approved files review for this study.

Microvascular decompression for glossopharyngeal neuralgia through a microasterional approach: A case series.

Background: Glossopharyngeal neuralgia (GPN) is an uncommon craniofacial pain syndrome. It is characterized by a sudden onset lancinating pain usually localized in the sensory distribution of the IX cranial nerve associated with excessive vagal outflow, which leads to bradycardia, hypotension, syncope, or cardiac arrest. This study aims to review our surgical experience performing microvascular decompression (MVD) in patients with GPN.

[Painful tic convulsif: Case series and literature review].

Background: The coexistence of hemifacial spasm and trigeminal neuralgia, a clinical entity known as painful tic convulsive, was first described in 1910. It is an uncommon condition that is worthy of interest in neurosurgical practice, because of its common pathophysiology mechanism: Neuro-vascular compression in most of the cases.

Objective: To present 2 cases of painful tic convulsive that received treatment at our institution, and to give a brief review of the existing literature related to this.

Surgical management of trigeminal neuralgia in elderly patients using a small retrosigmoidal approach: analysis of efficacy and safety.

Background: Trigeminal neuralgia is one of the most common causes of facial pain with the highest incidence in individuals > 60 years old. Despite the proven efficacy and safety of microvascular decompression (MVD) for the treatment of trigeminal neuralgia, some physicians are reluctant to perform the procedure in elderly patients because of potential complications.

Material And Methods: In the present study, we analyze the outcome of MVDs performed over a 10-year period in elderly patients and compare the results with those obtained in younger patients.
