Microsurgery of the larynx. An instrumental aid.

Microsurgery of the larynx involves working at some distance through a tube of relatively small diameter with fairly long instruments. High magnification with the operating microscope intensifies any manual tremor or quavering motion. A horizontal metal bar mounted on the laryngoscope light carrier provides a platform on which the instruments can be stabilized when the highest magnification is employed. Any abnormal motion of the distal ends of the instruments is thereby eliminated. The support does not interfere with the operator's vision since it lies outside the area of sharpest focus of the microscope, nor does it limit the excursion of the operating instruments.
