We describe a novel dual-functional optical coherence tomography (OCT) system with both a 3-D OCT real time scanner and a fiber probe using a sapphire ball lens for imaging and sensing the critical structures of the temporal bone. To prevent injury to facial nerve, 3-D visualization links anatomic landmarks to 3-D map of critical intracochlear structures. We used a graphics processing unit to boost the computing and 3-D rendering performance of swept source OCT. Both the intracochlear structures and facial nerve trunk of cadaveric human temporal bones are clearly identified with 3-D OCT volumetric rendering.
