BACKGROUND: Voice and swallowing impairments can impact on both quality of life and survival. Unilateral vocal fold paralysis (UVFP) as a result of distant metastasis can cause breathy voice and aspiration. The purpose of this study is to develop and evaluate a less invasive and effective alternative therapy for UVFP. METHODS: This was a retrospective review of prospectively enrolled patients at a tertiary referral center in Taiwan. Among a cohort of 177 patients who received intracordal hyaluronate injections, 2 had UVFP from distant metastasis and met the inclusion criteria...

Altered communication (hoarseness, dysphonia, and breathy voice) that can result from vocal fold paralysis, secondary to numerous etiologies, may be amenable to surgical restoration. In this article, both traditional and cutting-edge phonosurgical procedures targeting the symptoms resulting from vocal fold paralysis are reviewed, with emphasis on the characteristic imaging appearances of various injectable materials, implants, and augmentation procedures used in the treatment of vocal fold paralysis. In addition, complications of injection laryngoplasty and medialization laryngoplasty are illustrated...

INTRODUCTION: Injection laryngoplasty (IL) is typically performed either awake or under general anesthesia with paralysis. There is a subgroup of patients, however, for whom neither of these is a good option. For such patients, we report a hybrid technique that allows for a percutaneous injection without paralysis but with sedation to increase patient tolerance. Supraglottic airway laryngotracheal intervention (SALTI) brings the benefits of injection laryngoplasty to a group of patients previously underserved...
