Hypothesis:Injection laryngoplasty is just as good as medialization laryngoplasty (thyroplasty type I) for mild to moderate glottal insufficiency.
As the recent increase of options (materials and approaches) in vocal fold injection has occurred, the question of treatment selection between vocal fold injection and medialization laryngoplasty has been appropriately raised in a variety of venues. This subject begs the question: Is vocal fold injection equal, inferior, or better than medialization laryngoplasty?
