Laryngeal Function Study (LFS)


 

The LFS is an opportunity for patients to see what their voice can do with objective data to back it up. The LFS serves as another component of the voice evaluation. The LFS is performed by a Speech-Language Pathologist (SLP) with specialty training in the area of voice function. The LFS is a simple, non-invasive procedure which requires no preparation by the patient. The procedure takes approximately 20 minutes to complete. During the procedure, the patient will be asked to complete questionnaires related to their laryngeal/voice function. Then, the SLP will obtain a recording of the patient’s voice in a variety of contexts including talking, reading, sustaining a sound, along with pitch & dynamic range.  

Upon completion of the LFS, the patient will receive a report with details pertaining to laryngeal function. The report will be explained by the SLP, during which time the patient will have the opportunity to discuss the findings as well as any other questions they may have pertaining to their laryngeal function. The LFS serves as a baseline to which patients can refer. The baseline data helps to measure progress for patients who are in the process of voice rehabilitation. The baseline can also be used by a voice user (e.g., singer, salesman, teacher, etc.) as a guide in case they run into voice difficulty. They would be able to use their previous (healthy) baseline to see which areas have been affected by their current (unhealthy) difficulty and provide goals for them to work towards.
