Resumen
Patients with pituitary tumors and other masses at the bottom of the skull are at risk of brain infection and leaks of the fluid surrounding the brain when the tumor is removed surgically. To prevent these types of complications, surgeons have developed techniques to patch the surgical area with normal tissue taken from other parts of the body. In the past, this tissue was taken from the head, neck, and shoulder regions. Newer techniques allow the entire surgery to occur within the nose, resulting in fewer side effects and faster recovery. This includes taking normal tissue from within the nose to repair the base of the skull where the mass is removed. The nasoseptal flap is the most common method for this type of intranasal repair. In this paper, we describe the development and evolution of this surgical technique and discuss the impact that it has had on patient outcomes.
