Binocular microscopes have been used in surgical procedures since 1922.1 At present, those performing microsurgical procedures in both surgical and dental fields, including ophthalmology, neurosurgery, otolaryngology, plastic surgery, and endodontology, achieve stereoscopic visualization using binocular microscopes in operating rooms. Video recording of microsurgical procedures has conventionally been 2-dimensional; however, a 2-dimensional video recorder is inherently unable to provide as much appreciation of depth as a stereomicroscope. This circumstance can make teaching surgical skills and showcasing surgical technique more difficult, because a 2-dimensional video may not allow viewers, especially novices with little firsthand experience of microsurgical procedures, to fully appreciate the positioning and movement of a surgical instrument in relation to the patient’s magnified anatomy.
