Objective. To standardize the design of individually fitted implants based on computed tomographic (CT) images for use in medialization laryngoplasty without intraoperative voice monitoring. Study Design. Prospective tomographic and anatomical experimental study of 10 human cadaveric larynges. Methods. CT scans of 10 excised human larynges were analyzed to define the shape and size of ideal implants for medialization laryngoplasty. Silicone implants were designed according to CT parameters and used in simulated laryngoplasties in the laryngeal specimens. The efficacy of each implant in providing adequate medialization of the vocal fold was evaluated. Results. Diverse shapes and sizes of implants were obtained, reflecting variations in laryngeal anatomy. The implants enabled regular medialization of the entire extent of the free border of the vocal fold, including its posterior aspect. Medialization was considered adequate in all cases. Conclusions. This method proved to be a simple and efficient way to design individualized implants for medialization laryngoplasty, regardless of the size and shape of the larynx.
