Laser Application in Otolaryngology — Head and Neck Surgery

Since the discovery of the laser in 1959, a wide variety of lasers have been developed with numerous clinical applications in medicine and surgery. Lasers have had a great impact on the surgical approach to both benign and malignant diseases in Otolaryngology-Head and Neck Surgery, and have enabled the otolaryngologist to manage diseases in the aerodigestive system primarily through an endoscopic approach. We will summarize the physical properties of the currently used lasers in otolaryngology, as well as their clinical applications.

Xeroradiography and otolaryngology.

As a diagnostic tool, a new horizon in otolaryngology has become apparent in the past several years. It is known as xeroradiography and is a convenient technique requiring minimal patient cooperation and enjoying excellent acceptability for both patients and physicians. Speed, efficiency and consistently high image quality make xeroradiography suitable for otolaryngologic applications in the office, as well as in operating and emergency rooms. All tissue densities are represented in a single image, eliminating the need for taking two films of different densities, while radiation exposure in the same. Now popular for use in mammography, the technique is especially useful for detailed studies of the areas of interest to otolaryngologists. Certain inherent disadvantages in the technique are mentioned and guidelines are given to make these disadvantages an acceptable trade-off in actual application.

Argon laser microsurgery: its advantages and applications in otolaryngology.

AbstractPulsed lasers and continuous wave lasers were used experimentally in our laboratories. Because of their characteristics lasers are best suited for microsurgery. The Argon laser offers definite advantages: 1. a very small spot size; 2. selective destruction of tissues with red pigments; 3. in depth effect; and 4. it can be incorporated into the optical system of a standard operating microscope.The vocal cords of 24 mongrel dogs were exposed to different doses of argon laser irridation. The animals were sacrificed at intervals of up to 45 days. In all animals the destructive lesion was dose related, predictable and well circumscribed. Minimal edema followed the irradiations. Healing was complete by the third post irradiation week. The vocal cords were covered with normal looking mucosa. Scarring was minimal and muscle fibers and cartilage unaffected.

Technique of Microvascular Suture Anastomosis: Applications in Otolaryngology

MICROVASCULAR (vessels 3 mm or less are generally considered to satisfy the term "microvascular") anastomosis techniques have opened up new avenues of approach to transplantation and reconstructive surgery. The major problems precluding successful anastomosis of these minute blood vessels have involved the surgical technique and the tendency of thrombosis at the anastomotic site. The use of the operating microscope and recent innovations in suture materials and surgical instruments have all but eliminated the technical difficulties. Successful anastomosis may now be carried out on vessels 1 mm in diameter; however, postoperative thrombosis at the site of anastomosis, especially in veins, still poses a problem. There are several ways to anastomose small vessels; these techniques include: suture, staple, ring-pin, adhesive-electrocoaptive, and cuff ligature. For arteries in the microvascular range, the suture technique with magnification appears best. The purpose of this paper is to describe the method of microvascular suture anastomosis, discuss the
