Abstract

Extracorporeal video microscopes, or "exoscopes," provide high-definition views of the operative field and are alternatives to the operating microscope or loupes for large-corridor surgical approaches. In this proof-of-concept study, we aim to determine the feasibility of 3-dimensional exoscopes as alternatives to operating microscopes in otology and neurotology, espeically in conjunction with endoscopes. Eleven consecutive cases were performed using 3-dimensional exoscopes in place of, or as adjuncts to, the operating microscope. The exoscope was the sole visualization tool in 7 cases, with 4 including the use of an endoscope or microscope. There were no perioperative complications. Potential subjective advantages include superior ergonomics, compact size, and an equal visual experience for surgeons and observers. Limitations include low lighting in small surgical corridors and pixilation at high magnification. Exoscopes are potentially viable alternatives to the microscope in otologic and neurotologic surgery.
