Injection Laryngoplasty by Thyrohyoid Approach using Curved Cathelin Needle

Abstract

Injection laryngoplasty is performed for vocal fold paralysis or atrophy. When injection is performed as an office-based surgery under topical anesthesia, the trans-oral needle injection method has been popular. Because the needle is too long, some amount of injection material is left inside the vein. However, some patients cannot endure this procedure because of gag reflex. We perform percutaneous injection laryngoplasty using a curved 23G 60mm Cathelin needle through thyrohyoid approach. This method enables the surgeon to have better access to the whole vocal fold, from anterior to posterior in all directions. This method is very simple and useful and free of technical or medical failure.
