説明

A new surgical technique, the laryngoscopic procedures with the operating microscope for removal of singer's node's polyps or other benign lesions of the larynx, has been employed. Intruments invented and used for this technique include a supplemental lens attached to the conventional operating microscope, a modified direct laryngoscope through which a binocular view of the larynx can be obtained, a self-retaining chest arm attached to the larygoscope, vanious types of forceps and scissors and a small knife with a long handle.<BR>One hundred and fifty patients with laryngeal lesions were subjected to the current study.<BR>The advantages of microsurgery of the laryx are that 1) the lesions of the larynx are so magnified through the microscope that even minute changes invisiale to the naked eyes are well observed and meticulous procedures in the larynx are feasible, and 2) the binocular stereoscopic view of the larynx allows accurate and precise approach of the instruments to the lesion with the best focus on the forceps or knife and the lesion.<BR>Microsurgery can be usefully applied to surgical procedures of the larynx which may be impossible by the naked eye.<BR>Results of pre-and postoperative examinations of the patients phonation are discussed.<BR>In an experiment, the larynx of dogs was surgically manipulated by means of microsurgery and the histological examination was carried out on the removed larynx.
