The authors present their many years of experience in the area of laryngological surgery with various types of solid lasers. In our clinical practice we use Nd-YAG, Ho-YAG and Er-YAG surgical lasers. There are many reasons for applying lasers, depending on medical conditions. One of the most frequent cases are the nasal polyps, where surgical treatment is aimed at curing the results. For this type the procedures there was applied Nd-YAG laser, which has shortened the period of treatment and extended the remission. We also use this laser for mucal tissue corrections of the nasal conchs through deep coagulation effect. The above mentioned laser is also useful for the preventative treatment of granulation stenosis by removal of granulation tissue from different sections of the upper way; from the nose to the trachea.Other laser procedures in the nasal area include coagulation of Kisselbach locus, bleeding in Rendu-Osler disease, separating adhesions of the nasal concha from the nasal septum, coagulation of septal bleeding polyps, angiomas of different location, small papillomae of throat and nose, and reduction of hypertrophy nasopharyngeal mucoosa in OSAS patients, and uvolo-palato-pharyngoplasty (UPPP). Neodymium laser is also used for the management of neoplastic diseases in palliative and radical (CA. basocellulare) treatment for the resection of the premalignant changes (papilloma, leukoplakia) and early neoplastic changes of throat and larynx. Keloplasty in the area of larynx and trachea is performed with the use of Ho-YAG laser, with shallow effect, regardless of the density of tissue, enabling coagulation of vascular vessels. It enables non-traumatic resections of bone structures, such as the wall of maxillary sinus, nasal spine, or conchoplasty; the mucal tissue and the frame. Recent clinical tests are examining the possibilities of Er-YAG laser application for crushing calculus in the salivary ducts. Using lasers in laryngology enables their extensive application, and in many cases, as a method of treatment, it is superior effect wise to traditional methods. Laser beams are applied via special routes, which facilitates their adequate utilization.
