Why is voice therapy considered after injection augmentation in vocal fold paralysis?

Voice therapy is considered after injection augmentation in cases of vocal fold paralysis primarily to engage the respiratory and resonatory systems with the newly established phonatory system. Following an injection augmentation procedure, the goal is to improve phonation by enhancing the closure of the vocal folds. Voice therapy complements this by training the individual to effectively operate within the new anatomical configuration created by the injection.

Incorporating the respiratory system is critical, as breath support becomes essential for sustaining vocal quality and functioning. Additionally, resonatory techniques taught during therapy help optimize the quality of sound produced, ensuring that the person can make the best use of the augmented vocal folds. This integrated approach promotes more efficient voice production and encourages the patient to adapt to changes in their voice, maximizing treatment effectiveness.

Options that suggest preventing further paralysis or ensuring permanent voice restoration do not accurately capture the immediate purpose of post-injection therapy. While breath control may be a component of therapy, focusing solely on it would ignore other critical aspects of voice management needed after such an intervention. Hence, engaging both the respiratory and resonatory systems is crucial for effective voice rehabilitation post-injection augmentation.
