Trans-Sphenoidal Approach
The Trans-Sphenoidal Approach (TSA) is a surgical technique used to access and remove tumors in the brain. In this procedure, an incision is made through the nose and/or mouth, allowing a surgeon to access the sphenoid sinus cavity, which allows access to the pituitary gland and other surrounding areas of the brain. This type of approach is advantageous because it involves less risk of complications than a craniotomy, while providing access to a wide variety of tumors and other targets. TSA is also less invasive than traditional craniotomies, requiring less tissue damage and fewer risk of postoperative complications. It is used to treat skull base tumors, sellar and parasellar lesions, and vascular lesions in the pituitary fossa. This modern technique thus allows for more precise tumor removal with better preservation of surrounding functional tissue, greater accuracy and better visual control for the surgeon, and improved clinical outcomes for the patient.
