Stabilization of costal cartilage graft warping using infrared laser irradiation in a porcine model.
OBJECTIVE To develop a method to rapidly stabilize the shape change process in peripheral slices of costal cartilage by using infrared laser irradiation in a porcine model. METHODS Forty peripheral porcine costal cartilage specimens (40 × 10 × 2 mm) were harvested. Thirty of these specimens were immediately irradiated with an Nd:YAG laser (λ = 1.32 μm; spot size, 2-mm diameter) using 1 of 3 e...
متن کاملNumerical analysis of costal cartilage warping after laser modification
Grafts obtained from peripheral regions of costal cartilage have an inherent tendency to warp over time. Laser irradiation provides a potential method to control the warping process, thus yielding stable grafts for facial reconstructive surgery. In our current study, we propose a simple and well-fitting model that numerically describes the degree of warping of laser irradiated costal cartilage ...
متن کاملConcentric and eccentric carved costal cartilage: a comparison of warping.
OBJECTIVE To determine if a systematic, concentric graft-carving technique results in less warping than eccentric carving. METHODS Costal cartilage from ribs 3 through 9 were harvested from fresh human cadavers. Concentric dorsal grafts were carved from cartilage obtained from one side of the cadaver (n = 7) and eccentric grafts were carved from the opposite side (n = 11). After carving, graf...
متن کاملHarvesting split thickness costal cartilage graft
AIM There are few complications associated with harvesting of full thickness coastal cartilage grafts i.e., pneumothorax (0.9%), contour deformities and prolonged post-operative pain. To address these issues, authors devised special scalpel to harvest split-thickness costal cartilage grafts. MATERIALS AND METHODS Standard inframammary incision was used for harvesting rib. Incision was made di...
متن کاملModeling the Thermal Response of Porcine Cartilage to Laser Irradiation
During laser irradiation of biological tissue, a number of physical processes take place that determine temperature elevation and thermal damage rates. Some of those important to laser–tissue interaction are: 1) propagation of light in scattering media; 2) transformation of laser light into photochemical, acoustic, or thermal energy; 3) tissue–tissue and tissue–environment heat and mass transfe...
