Abstract

To develop phonosurgical techniques, the authors investigated the healing mechanisms of wounds on the vocal folds of canine larynges, and devised a method to cover the raw surfaces of such wounds. To restore the normal physiologic properties of the vocal folds, the normal mucosa should be removed as little as possible in phonosurgery. When the mucosa of the vocal folds is extensively removed by surgical intervention and the raw surface cannot be covered with the local pedicle flap, it should be covered with a free mucosal flap. We found an activated human fibrinogen concentrate, which is a biologic tissue adhesive, to be suitable for adhering a free mucosal flap to the raw surface by a laryngomicrosurgical approach.
