[Possibilities of the use of surgical laser irradiation in spontaneous formation of cartilage tissue in ENT plastic surgery].

The experiments were made to study CO2-laser ability to promote spontaneous formation of nasal septum cartilage. Laser-induced changes in physical and histological characteristics of the cartilage tissue were followed up. Optimal regimens of radiation were selected which allowed to modify cartilage shape without impairment of its morphological and histological structure. In vivo tests were performed on rabbit auricular floor cartilage. The present shape of the cartilage remained stable. It is inferred that laser energy may be a promising tool in plastic ENT surgery.
