• A new micromanipulator with microspot capability has been developed for carbon dioxide laser surgery in otolaryngology. The instrument features new infrared optics, which provide smaller laser spot sizes than those achievable with conventional micromanipulators (300 μm using a 400-mm operating microscope lens). The conventional red helium-neon aiming laser is replaced with a nonlaser fiberoptic image, and a power defocus control on the joystick manipulator eliminates external defocus controls. Less surrounding tissue trauma occurs with this new instrument by using a higher power density with average power settings of 1 to 2 W for cutting and ablation of tissue. Eight patients with benign laryngeal disease and one patient with dysplastic changes of the vocal cord were treated successfully without complications.
