Endoscopic skull base surgery is a minimally invasive surgical approach used to treat a variety of conditions located at the base of the skull, including tumors, cysts, and congenital anomalies. This technique utilizes advanced endoscopic tools and imaging technology to access and address abnormalities through the nasal passages, thereby avoiding large external incisions.

During endoscopic skull base surgery, surgeons use a high-definition endoscope, which is a thin, flexible tube equipped with a camera and light, to navigate through the nasal passages to the base of the skull. The endoscope provides real-time visual guidance, allowing surgeons to precisely locate and remove or repair the targeted pathology. Specialized instruments are used alongside the endoscope to perform the necessary surgical maneuvers.

This approach is indicated for a wide range of conditions, including pituitary tumors, cerebrospinal fluid leaks, chordomas, meningiomas, and other benign or malignant growths located at the skull base. It is particularly beneficial for tumors that are difficult to access through traditional open surgical methods.

Endoscopic skull base surgery offers several advantages over traditional open surgery, including reduced trauma to surrounding tissues, shorter recovery times, less postoperative pain, and minimized scarring. The approach also allows for better preservation of critical structures and functions. However, potential risks include cerebrospinal fluid leaks, infection, bleeding, and injury to nearby nerves and blood vessels.
