title: Sandwich Thyroplasty: A Novel Technique for Simplifying Medialization of Vocal Fold Using Silicone Implant in Paralytic Dysphonia with Modification of Thyroplasty Window.
abstract: A novel technique of thyroplasty-Sandwich thyroplasty-described, with modification of Isshiki's thyroplasty window to overcome the problems of securing and stabilising the silicone implant in the window thus simplifying the medialization of the vocal fold. Seventy five patients diagnosed with paralytic dysphonia of varied etiology, attending Sri Sathya Sai Institute of ORL, Guntur, India from January 2005 to January 2012, were subjected to this new technique. Medialization of vocal fold was achieved by sandwiching and stabilising a silicone implant between a superiorly based cartilaginous hinged door and the inner perichondrium of the modified thyroplasty window. Results were analysed based upon pre and postoperative voice handicap index, maximum phonation time readings and video-stroboscopic findings. The results were statistically significant with no untoward complications. Sandwich thyroplasty technique facilitated easier fixation and stabilization of silicone implant avoiding difficult and time consuming, techniques involving flanges or sutures.
