The surgical outcomes for OGMs remained consistent during the transition from using a microscope to an exoscope. The exoscope is a safe tool in the surgery of OGMs, even when operating on large tumors. The wider range of angular movement of the camera head is particularly advantageous when accessing the anterior skull base. In line with this, exoscope-assisted surgeries relied more on tilting movements, whereas microscope-assisted surgeries required more horizontal adjustment.
