Abstract
Objective: In order to overcome the drawback of 2D videolaryngoscopy, we have developed a newly devised 3D videolaryngoscope, and we evaluated the usefulness of this device.
Method: A 3D high vision camera of 5 mm in diameter was attached to a usual 2D laryngoscope. Real time images were monitored by a dome-shaped 3D monitor (Panasonic Health Care). We performed endolaryngeal microsurgery on some patients with voice disorders, and compared usefulness between 2D, 3D, and conventional binocular system.
Results: Using 3D videolaryngoscope allowed better and easier manipulation in grasping and cutting the lesion, and even in suturing the laryngeal mucosa because of its stereoscopic visual effect, as compared to 2D scope. In comparison to the conventional binocular microscopy, 3D videoscope offered equivalent stereoscopic imaging and an advantage in nearer positioning to the patient, resulting accurate operation.
Conclusion: Our study indicates that 3D imaging offers significant advantages in the performance of endolaryngeal microsurgical skills to every surgeon.
