Feedback-controlled laser-mediated cartilage reshaping.
OBJECTIVE To demonstrate feedback-controlled laser-mediated cartilage reshaping using dynamic measurements of tissue optical properties and radiometric surface temperatures. DESIGN Flat cartilage specimens were reshaped into curved configurations using a feedback-controlled laser device. MATERIALS Fresh porcine nasal septum, stripped of perichondrium and cut into uniform strips (25 x 10 x 1...
متن کاملLong-term viability and mechanical behavior following laser cartilage reshaping.
OBJECTIVE To investigate the long-term in vivo effect of laser dosimetry on rabbit septal cartilage integrity, viability, and mechanical behavior. METHODS Nasal septal cartilage specimens (control and irradiated pairs) were harvested from 18 rabbits. Specimens were mechanically deformed and irradiated with an Nd:YAG laser across a broad dosimetry range (4-8 W and 6-16 seconds). Treated specim...
متن کاملElectromechanical reshaping of septal cartilage.
OBJECTIVES This study describes the process of tissue electroforming and how shape changes in cartilage can be produced by the application of direct current (DC). The dependence of shape change on voltage and application time is explored. STUDY DESIGN Basic investigation using ex vivo porcine septal cartilage grafts and electromechanical cartilage deformation focused on development of a new s...
متن کاملViability and Regeneration of Chondrocytes after Laser Cartilage Reshaping Using 1,460 nm Diode Laser
OBJECTIVES Cartilage reshaping by laser irradiation is used to correct septal and auricular cartilage deformities. Chondrocyte viability following laser irradiation and reshaping has been well established. However, the regeneration process of chondrocyte after laser irradiation has not been revealed yet. The aims of this study were to determine the mechanism of cartilaginous thermal injury and ...
متن کاملFeedback controlled laser system for safe and efficient reshaping of nasal cartilage
In 1992, we identified laser-induced stress relaxation in cartilage. This led to the development of a new laser application in otolaryngologyhead and neck surgery for the non-ablative reshaping of cartilage. Laser septochondrocorrection is non-invasive, bloodless, painless procedure which takes only 10 minutes to complete and can be performed in outpatient settings. The efficacy and safety of t...
