Brief Summary
The purpose of this study is to measure the short- and long-term voice outcome and outcome predictors of glottoplasty, cricothyroid approximation, thyroplasty, and chondrolaryngoplasty using a prospective non-randomized controlled trial and a multidimensional voice assessment protocol. Secondly, a laryngeal magnetic resonance imaging protocol will be developed to measure pre- and postoperative anatomical factors and compare them with the acoustic changes.
