Abstract It is difficult to permanently alter the shape of cartilage in a controlled way. In otolaryngology and plastic surgery several procedures are done to alter the shape of cartilage, for example the correction of a deviated nasal septum and surgery for bat ears. The aim of this paper is to study the main parameters which are necessary for the phenomenon of reshaping of cartilage under non-destructive laser radiation. We have measured temperature and stress in cartilage when it is being reshaped with a holmium laser, It has been shown that laser-induced stress relaxation in cartilage takes place when the tissue temperature exceeds 70°C. We have determined the conditions which allow the shape of cartilage to be altered without producing any pronounced alteration to matrix structure or chondrocytes.
