Benign Vocal Fold Lesions - Principles of Management - Dinesh K. Chhetri, MD - UCLA Health

Explore the principles of managing benign vocal fold lesions in this informative lecture by Dr. Dinesh K. Chhetri, a laryngologist and Professor at UCLA's Department of Head and Neck Surgery. Delve into the anatomy and histology of vocal folds, focusing on common benign growths of the larynx. Learn about the body cover layer model, biomechanical aspects of vocal fold vibration, and the crucial role of the lamina propria. Discover various vocal fold lesions, including nodules, polyps, cysts, fibrous masses, granulomas, and papillomas. Gain insights into phonosurgery principles and microflap surgery techniques for treating these conditions. Understand the pathophysiology of vocal cord cysts and explore treatment options for different vocal fold lesions, including vocal process granulomas and papillomas.
