In evaluation of a patient with a vocal fold issue, what is a key feature to assess?

Assessing the presence of a glottal gap is crucial in the evaluation of a patient with a vocal fold issue because it directly relates to vocal fold function and closure during phonation. A glottal gap refers to the space that may exist between the vocal folds when they close, which can significantly impact the quality, breathiness, and overall sound of the voice. When the vocal folds do not close completely, it can lead to difficulties such as hoarseness and ineffective voice production, which are common concerns in patients with voice disorders.

The evaluation of the glottal gap is typically performed through various methods, including videolaryngoscopy, which allows clinicians to visualize the vocal folds in action. Identifying a glottal gap can help in making a diagnosis, guiding treatment options, and predicting outcomes for voice therapy or surgical interventions.

While assessing symmetry of lip movement, intensity of voice output, and rate of speech are important components of a comprehensive speech evaluation, they do not directly address the specific function and condition of the vocal folds themselves. Therefore, the presence of a glottal gap stands out as a key feature that directly informs the clinician about the state and functionality of the vocal folds, making it essential in the assessment of vocal issues
