Laser surgery for benign laryngeal disease. Conservation and ergonomics.

In surgery, the era of tissue conservation and advanced engineering ergonomics has arrived. As a surgical tool, lasers will undergo extensive development. The most precise of surgical tools, its ability to focus to spots equal to its wavelength will permit intracellular surgery. A new technology must be mastered by the operator, who must have a solid foundation in laser physics. The small spot size possible with the new laser laryngoscopy coupler introduces one more refinement in the growing trend toward "conservational" surgery of the larynx for both benign and malignant laryngeal disease.
