ABSTRACT
Cartilage laser thermoforming, also known as laser reshaping, is a new surgical procedure that allows in-situ treatment of
deformities in the head and neck with less morbidity than traditional approaches. During laser irradiation, cartilage becomes
sufficiently subtle or deformable for stretching and shaping into new stable configurations. This study describes the
experimental and theoretical characterization of the thermal response of porcine cartilage to laser irradiation (Nd:YAG). The
surface temperature history of cartilage specimens was monitored during heating and thermal relaxation; using laser
exposure times ranging between 1 and 15 s and laser powers of 1 to 10 W. The experimental results were then used to
