This article discusses the surgical technique of endoscopic endonasal pituitary sacrifice (EE-PS) for selected complex tumors with retrochiasmatic and retroclival extension. The study describes the relevant surgical anatomy and step-by-step operative technique of EE-PS. The authors also report their clinical experience with 13 patients who underwent EE-PS, including their indications, outcomes, and complications. The article concludes that EE-PS is a feasible surgical option to improve visibility and accessibility to the retroclival and retrochiasmatic space, thus increasing tumor resectability.

This article, published in the Journal of Neurological Surgery, discusses a case study of a 65-year-old man with a recurrent clival chordoma. Despite previous surgery and radiotherapy, the tumor had progressed significantly. The article presents a video demonstrating the use of an expanded endoscopic transpterygoid transcavernous approach for tumor resection. Skull base reconstruction was performed using a temporoparietal fascia flap. The article provides valuable insights for researchers and medical professionals studying chordoma treatment options.

A 17-year-old boy with a history of frontal headaches who presented with decreased vision and bitemporal hemianopsia. He was found to have a large, heavily calcified sellar, suprasellar, and third ventricular mass, consistent with craniopharyngioma. He underwent endoscopic endonasal transtuberculum approach for resection of tumor with anatomical preservation of the pituitary gland and infundibulum. Postoperative MRI showed gross total resection. He was neurologically intact at the last follow-up.By Kelly Shaftel; John Craig; Amrita Ray; Jacob Eide and Karam AsmaroReported by Author; Author; Author; Author; Author [Extracted from the article]

This article discusses the use of bedside skull X-rays and high fraction inspired oxygen (FIO2) therapy for monitoring and treating postoperative pneumocephalus in patients undergoing expanded endoscopic endonasal surgery (EEA) for skull base tumors. The study found that bedside skull X-rays were effective in monitoring pneumocephalus and identifying cases of worsening pneumocephalus due to over drainage. Additionally, high FIO2 therapy was shown to accelerate the resorption of trapped air in the intracranial cavity. The use of bedside X-rays reduced the need for CT scans, resulting in cost savings and reduced radiation exposure. [Extracted from the article]

This article discusses the safety of vidian neurectomy, a surgical procedure that involves removing the vidian nerve, during endoscopic endonasal skull base surgery. The objective of the study was to determine the incidence of symptomatic dry eyes (Keratoconjunctivitis Sicca or KCS) in patients who underwent vidian neurectomy. The study reviewed the cases of 13 patients who underwent the procedure and found that none of them reported symptomatic dry eyes at follow-up visits. The authors concluded that vidian neurectomy is well-tolerated and does not lead to KCS symptoms in patients. [Extracted from the article]

This article discusses seven different techniques for pituitary transposition in endoscopic endonasal surgery. The techniques are categorized based on their relationship with the dura mater and include extradural, hybrid extradural/intradural, interdural transcavernous, extended interdural transcavernous, intradural hemitransposition, intradural, and pituitary sacrifice. The article evaluates the clinical application and selection of these techniques in different anatomical regions and types of pathology. The authors emphasize the importance of selecting the most appropriate technique based on the specific case and preoperative pituitary function for successful surgical outcomes.

This article discusses the use of endoscopic endonasal transcavernous surgery for pituitary adenomas that invade the cavernous sinus. The study found that this surgical approach is safe and effective, allowing for complete resection of previously incompletely treated tumors. The researchers also noted that despite the theoretical risk of venous thrombosis, no patients in the study developed cavernous sinus thrombosis postoperatively. The article provides clinical, radiographic, and vascular outcomes of patients who underwent this surgery, highlighting the importance of this technique in treating pituitary adenomas with cavernous sinus invasion.

This article, published in the Journal of Neurological Surgery, examines the diagnostic accuracy of beta-2 transferrin gel electrophoresis (B2Tf GE) in detecting cerebrospinal fluid (CSF) rhinorrhea. The study conducted a retrospective review of patients who presented with unilateral thin clear rhinorrhea (UTCR) and underwent B2Tf GE. The results showed that B2Tf GE had a sensitivity of 87.5%, specificity of 76.9%, positive predictive value of 77.8%, and negative predictive value of 87% in detecting CSF rhinorrhea. However, the study also highlighted the potential limitations of B2Tf GE and suggested considering other diagnostic tests in cases where B2Tf GE results deviate from clinical suspicion.
