Electromechanical reshaping of ex vivo porcine trachea.
OBJECTIVES The trachea is a composite cartilaginous structure particularly prone to various forms of convexities. Electromechanical reshaping (EMR) is an emerging technique used to reshape cartilaginous tissues by applying electric current in tandem with imposed mechanical deformation to achieve shape change. In this study, EMR was used to reshape tracheal cartilage rings to demonstrate the fea...
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 کاملMonitoring of electrical current in rabbit and porcine cartilage tissue during electromechanical reshaping
Electro Mechanical Reshaping (EMR) with platinum needle electrodes has been recently developed to shape cartilage without conventional cut and suture surgery. This study investigates the relationship between the voltage applied, the electrical current measured during EMR with platinum needles, and the resulting shape. Monitoring the electrical current provides information to model the electro-c...
متن کاملIn vivo needle-based electromechanical reshaping of pinnae: New Zealand White rabbit model.
IMPORTANCE Electromechanical reshaping (EMR) is a low-cost, needle-based, and simple means to shape cartilage tissue without the use of scalpels, sutures, or heat that can potentially be used in an outpatient setting to perform otoplasty. OBJECTIVES To demonstrate that EMR can alter the shape of intact pinnae in an in vivo animal model and to show that the amount of shape change and the limit...
متن کاملLong-term in vivo electromechanical reshaping for auricular reconstruction in the New Zealand white rabbit model.
OBJECTIVES/HYPOTHESIS To demonstrate the dosimetry effect of electromechanical reshaping (EMR) on cartilage shape change, structural integrity, cellular viability, and remodeling of grafts in an in vivo long-term animal model. STUDY DESIGN Animal study. METHODS A subperichondrial cartilaginous defect was created within the base of the pinna of 31 New Zealand white rabbits. Autologous costal...
