Transorbital endoscopic approach for repair of a lateral sphenoid sinus cerebrospinal fluid leak.

The transorbital craniotomy represents a minimally invasive approach to the mesial structures of the middle fossa. This video depicts the approach to the lateral sphenoid recess in a patient with CSF rhinorrhea secondary to a lateral sphenoid encephalocele. The transorbital approach represents a unique advantage to repairing the lateral sphenoid sinus in comparison to the endoscopic endonasal approach, which requires traversing, and often transecting, the vidian nerve.

Preoperative PET/MRI and radio-guided surgery using [Cu64]DOTATATE in meningioma: a feasibility study. Illustrative case.

Background: Meningiomas are the most common primary intracranial neoplasms. Gross-total resection, the primary treatment goal, is not achieved in up to 50% of patients, affecting progression-free and overall survival. The traditionally used intraoperative assessment of resection extent using the Simpson grade has recently been shown to be less accurate than postoperative MRI.

Feasibility and Morbidity for the Use of MR-Guided Laser-Induced Thermotherapy for the Treatment of Skull Base Tumors: A Report of Three Cases.

 Laser-induced thermotherapy (LITT) is a minimally invasive technique that has been demonstrated as an effective treatment of many pathologies; however, it has never been investigated for the use in skull base tumors.  Three patients underwent LITT for treatment of skull base meningiomas. All three patients were determined to be poor candidates for open resection.

Infratemporal Fossa Vascular Anatomy Pertinent to Percutaneous Access to the Foramen Ovale for Treatment of Trigeminal Neuralgia: A Comparison of Cadaveric Dissection and Computed Tomography Analysis.

Background: Trigeminal neuralgia may be treated via percutaneous access to the foramen ovale (FO). Vascular complications associated with the needle trajectory can result in serious morbidity and mortality. This study aimed to correlate the vascular relationships of the FO at the skull base via cadaveric dissections and computed tomography (CT).

Contralateral Transmaxillary Approach for Resection of Chondrosarcoma of the Petrous Apex: A Case Report.

Background: Deep location and neurovascular structures make access to lesions of the petrous apex a significant challenge. A novel approach for these tumors is the contralateral transmaxillary approach.

Clinical Presentation: A 31-year-old male was evaluated for left abducens nerve palsy.

An investigation into quality of life improvement in patients undergoing microvascular decompression for hemifacial spasm.

OBJECTIVE Hemifacial spasm (HFS) is a movement disorder characterized by involuntary spasms of the facial muscles, and it can negatively impact quality of life (QOL). This retrospective study and systematic review with meta-analysis was conducted to investigate the QOL in patients with HFS following intervention with microvascular decompression (MVD) and botulinum toxin (BT). METHODS In the retrospective analysis, a QOL questionnaire was administered to all patients undergoing MVD performed by a single surgeon.

Utility of the intensive care unit in patients undergoing microvascular decompression: a multiinstitution comparative analysis.

OBJECTIVE Use of the ICU during admission to a hospital is associated with a significant portion of the total health care costs for that stay. Patients undergoing microvascular decompression (MVD) for cranial neuralgias are routinely admitted postoperatively to the ICU for monitoring. The primary purpose of this study was to compare complication rates of patients with and without a postoperative ICU stay following MVD.

Retinal Structures and Visual Cortex Activity are Impaired Prior to Clinical Vision Loss in Glaucoma.

Glaucoma is the second leading cause of blindness worldwide and its pathogenesis remains unclear. In this study, we measured the structure, metabolism and function of the visual system by optical coherence tomography and multi-modal magnetic resonance imaging in healthy subjects and glaucoma patients with different degrees of vision loss. We found that inner retinal layer thinning, optic nerve cupping and reduced visual cortex activity occurred before patients showed visual field impairment.
