Evaluation of the Dysphonic Patient (in: Function Preservation in Laryngeal Cancer).

The evaluation of the dysphonic patient begins with a complete understanding of the laryngeal anatomy and physiology of voice production. A thorough history must be taken regarding the dysphonia qualities, alarming symptoms, and confounding factors. The complete head and neck examination culminates in a detailed visualization of the vocal folds using image-capturing laryngoscopy as well as stroboscopy or high-speed digital imaging to fully evaluate the viscoelastic properties of the vocal fold cover-body structure and function. Finally, the evaluation leads to the biopsy of any concerning lesions either under magnification in the operating room or topical anesthesia in the office.
