Laser Septochondrocorrection

Laser-induced regeneration of cartilage

“…60,80,81 It was first used in clinics for the correction of nasal septum deformities and for reshaping ears. [82][83][84][85] The prospects of laser reshaping of costal and tracheal cartilages as well as the epiglottis have also been demonstrated. [85][86][87] The histological results of in vivo experiments on laser reshaping of porcine ears have shown the growth of hyaline cartilage at the periphery of the zone where laser-induced transformation of cartilage matrix structure occurred.…”

“…Such time can vary from a few hours up to two weeks for different laser settings. 84,88 Thus, the precise choice of laser parameters allows control of the extent of the neogenetic tissue emerged as a result of laser-induced regeneration process.…”

Laser cartilage reshaping in an in vivo rabbit model using a 1.54 μm Er:Glass laser

“…Several wavelengths have since been evaluated: Diode laser (l ¼ 0.98 mm) [4], Nd:YAG laser (l ¼ 1.32 mm and l ¼ 1.44 mm) [5][6][7], Ho:YAG laser (l ¼ 2.1 mm) [8], Er:YAG laser (l ¼ 2.94 mm) [9] and CO 2 laser (l ¼ 10.6 mm) [10]. Recently, Ovchinnikov et al have performed a clinical series of 110 patients who underwent in situ laser nasal septal cartilage reshaping [11]. They used Ho:YAG (2.1 mm) laser radiation to heat composite nasal septal tissue (mucosa and cartilage) to correct septal deformities without gross disruption of the integrity of the mucosa, perichondrium and cartilage.…”

Characterization of temperature dependent mechanical behavior of cartilage

“…Laser assisted reshaping of cartilage is a new surgical procedure designed to allow in-situ treatment of deformities with less morbidity than traditional procedures [1][2][3][4][5][6][7][8][9][10][11][12][13]. During laser irradiation, mechanically deformed cartilage undergoes a subtle change in material properties that permits tissue to be reshaped into new stable configurations [5,6,11,12,[14][15][16][17][18][19][20][21][22].…”
