However, a multidisciplinary team approach can ensure appropriate management of these tumor types, he explained, adding that only a handful of institutions are performing these surgeries.
One advantage of endoscopic skull base surgery is that it is minimally invasive, said Dr. Batra. Additionally, the rigid endoscope is a tool that provides brilliant illumination and magnification to detect tumor origin and boundaries and allows surgeons to see around corners. The endoscope allows superb exposure to the sphenoid sinuses, frontal recess and frontal sinus, and the orbital apex, said Dr. Batra, adding that this, in turn, aids with precise tumor removal.
The endoscopic approach to skull base surgery improves visualization, agreed Dr. Snyderman. However, he views the procedure as being maximally, not minimally, invasive. “The endoscope has extended the limits of skull base surgery, and we’re getting to areas we couldn’t get to before,” he said. “It’s maximally invasive but avoids the morbidity of extracranial approach.”
