Abstract
Background and Objectives: Silicone, Gore- Tex, Gelfoam, Collagen and autologous fat are used for thyroplasty in case of vocal fold paralysis or paresis. These implants have many advantages, such as biocompatibility, low price and easy handling and accessibility. But additional voice modification is impossible using these materials. So, we design new thyroplasty technique, called balloon thyroplasty using Foley catheter.

Materal and Methods: The fresh human larynx was dissected in midline posteriorly. Minithyrotomy hole was created using 5mm cutting burr in the midline of thyroid cartilage. Subperichondrial dissection was done using Duckbill elevator up to vocal process. Balloon catheter(1.5cm balloon size) was inserted through the subperichondrial tunnel. The balloon was inflated to medialize the vocal cord.

Results: After ballooning, the true vocal cord medialized mimicking thyroplasty.

Conclusion: The authors found that Balloon thyroplasty could be a good candidate for vocal fold medialization technique. The technical refinement and in vivo safety are reserved for the ongoing study.
