CO2 laser digital scanning system and injectable collagen for the treatment of sulcus vocalis

Sulcus vocalis is one of the most difficult benign laryngeal lesions to manage. This article describes the authors' technique for treatment of sulcus vocalis using the CO2 laser digital scanning system and injectable collagen. The aim of this surgery is to increase the pliability of the vocal folds and decrease the glottal gap. The surgical technique is based on the concept of Cornut and Bouchayer, where the dissection of the epithelium adherent to the deep subepithelial plane improves the vocal fold vibration. When the vocal fold is atrophic, surgery is completed by collagen injection. This technique, combined with speech therapy, improves significantly voice efficiency.
