This article discusses the outcomes of endoscopic endonasal transcavernous surgery for pituitary adenomas. The study analyzed data from patients who underwent this surgery between 2018 and 2023. The results showed that transcavernous surgery was more common in repeat surgery patients and those with functioning adenomas. The study also examined the invasion patterns of the cavernous sinus compartments and found that the medial wall was the most frequently involved. The authors concluded that the outcomes of transcavernous surgery can vary depending on the specific compartments involved. [Extracted from the article]

This article discusses the surgical management and outcomes of pituitary adenomas with subarachnoid invasion. The study analyzed data from 321 patients who underwent an endoscopic endonasal approach for pituitary adenoma resection, and identified 13 patients with subarachnoid invasion. The surgical approach for these tumors involved careful dissection from surrounding neurovascular structures to achieve safe resection. Patients with subarachnoid invasion were more likely to have subtotal tumor resection and require additional treatment, such as medical therapy, radiation, or repeat resection. They also experienced higher rates of intra-operative CSF leak, postoperative diabetes insipidus, post-operative hematomas, and the need for adjuvant interventions. Overall, pituitary adenomas with subarachnoid invasion present unique challenges and require specialized surgical techniques. [Extracted from the article]

This article, published in the Journal of Neurological Surgery, examines the impact of the transcavernous extension of the endonasal endoscopic approach on posterior pituitary function for the resection of pituitary adenomas. The study retrospectively reviewed 290 patients who underwent endoscopic endonasal resection of pituitary adenomas and compared the incidence of postoperative diabetes insipidus (DI) between groups based on the occurrence of transcavernous extension. The results showed that the transcavernous approach with medial wall of the cavernous sinus (MWCS) resection did not increase the risk of postoperative DI. [Extracted from the article]

This article, published in the Journal of Neurological Surgery, explores the patency of the cavernous sinus (CS) after medial wall resection. The study included 66 patients who underwent endoscopic endonasal approach (EEA) surgeries to resect CS-invading tumors. The results showed that CS patency was achieved in 85% of patients within the first 12 months and 92% by 18 months. Bilateral resection of the CS medial wall and resection for the removal of meningiomas were associated with increased rates of nonpatency. However, the study found that patency versus nonpatency did not have any significant difference in postoperative adverse events or effects. [Extracted from the article]

This article, titled "Outcomes of the Middle Turbinate Swing Technique during the Expanded Endonasal Approach (EEA): A Tertiary Center Experience," explores the use of the middle turbinate (MT) swing technique in skull base surgery. The MT swing technique involves detaching the posterior and lateral attachments of the middle turbinate to allow it to swing laterally into the maxillary sinus, providing better access to the skull base. The study analyzed surgeries performed between January 2021 and August 2023, finding that the MT swing technique did not compromise skull base exposure or tumor resection and had low rates of complications. The authors suggest that further research is needed to investigate the long-term benefits of preserving the middle turbinate during skull base surgery. [Extracted from the article]
