Endoscopic skull base surgery involves the treatment of various types of tumors and with an endoscope. An endoscope is a specialized instrument, which can reach inaccessible regions with ease. It is capable of removing entire tumors without the need for incisions. Endoscopic surgery is effective for tumors of the sinuses and craniofacial areas. Other conditions that can be treated with an endoscope include sinonasal tumors, inverted papillomas, esthesioneuroblastomas, cerebrospinal fluid leaks, pituitary tumors, and meningiomas. Several test and procedures may precede the endoscopy like an MRI or a CT scan. The procedure is performed under general anesthesia. Depending on the nature of the surgery, the endoscope may be inserted into the nasal cavity. In other instances, a small incision may be made between the hair of the eyebrow, a skin crease or bridge of the nose or the scalp depending on the location of the tumor. A highly specialized endoscope with a probe and a lens is used for the procedure. The probe can be maneuvered into small groves and areas hidden behind the skeletal structure. The camera and the lens project magnified images on a large screen for precise diagnosis and analysis by the team of the surgeon. Other specialized instruments are inserted through the endoscope for excision of tumors and growths. Endoscopy allows the surgeon to operate on the abnormal growth without causing much disturbance to the surrounding tissues and structures. The procedure causes minimal pain and the patient recovers quickly.
