In this series of SIG 3 articles, a foundation for laryngeal endoscopic imaging and interpreting videostroboscopic parameters is provided. These concepts are then put into practice in the context of three case studies focused on muscle tension dysphonia, bilateral vocal fold lesions, and vocal fold immobility. In the cases, auditory perceptual analysis, acoustic and aerodynamic measures, and candidacy for voice therapy are assessed in addition to videostroboscopic parameters. Video and audio examples are included to provide an interactive experience for the reader.

Learning Outcomes
You will be able to:

• describe the laryngeal imaging techniques of videoendoscopy and videostroboscopy, including distinctions and clinical uses
• explain the auditory-perceptual characteristics of the voice using the sustained /a/ vowel and Consensus Auditory-Perceptual Evaluation of Voice sentences in the provided .wav file
• define normal and abnormal acoustic and aerodynamic outcomes of the voice assessment
• interpret videostroboscopic ratings of muscle tension dysphonia, bilateral vocal fold lesions, and unilateral vocal fold paralysis

Assessment Type
Self-assessment—Think about what you learned and report on the Completion Form how you will use your new knowledge.
