Fiberoptic Endoscopic Evaluation of Swallowing (FEES): Assessing and Diagnosing DysphagiaHave you ever experienced difficulty swallowing or felt like food was getting stuck in your throat? These can be signs of a condition called dysphagia, which affects the ability to swallow.
If you’re experiencing these symptoms, a fiberoptic endoscopic evaluation of swallowing (FEES) test may be recommended by a speech-language pathologist. In this article, we will explore the procedure and purpose of FEES, as well as the various reasons why someone might need this test.
Fiberoptic Endoscopic Evaluation of Swallowing (FEES)
Procedure and Purpose of FEES Test
FEES is a diagnostic procedure performed by a speech-language pathologist to assess swallowing function. During the test, a thin, flexible instrument called a fiberoptic endoscope is passed through the nostril and guided into the throat.
This instrument has a small camera on the end, which allows the speech-language pathologist to view the throat in real-time during swallowing. The primary purpose of the FEES test is to evaluate the coordination and movement of the muscles involved in swallowing, such as the pharynx, larynx, and esophagus.
It also helps assess coordination with breathing, which is essential for safe swallowing. By visualizing these structures, the speech-language pathologist can identify any abnormalities or dysfunctions that may be contributing to the patient’s swallowing difficulties.
Components of Swallowing and How FEES Assesses Them
Swallowing is a complex process involving multiple components. It begins when food or liquid is introduced into the mouth and ends when it reaches the stomach.
The process requires a coordinated effort of the tongue, pharynx, larynx, epiglottis, and esophagus. Any disruption in this coordination can lead to dysphagia.
FEES utilizes the fiberoptic endoscope to visualize the various stages of swallowing. The speech-language pathologist can observe the movement of the structures involved in swallowing, ensuring that the epiglottis is closing off the trachea, preventing food or liquid from entering the airway.
They can also identify any abnormalities in muscle movements or inefficient clearance of food or liquid from the throat. The video screen visualization during the FEES test allows for a detailed examination of the swallowing process, and the images can be recorded for further analysis and documentation.
This provides a comprehensive assessment of swallowing function, aiding in the development of an appropriate treatment plan.
Reasons for Needing a FEES Test
Symptoms and Conditions Related to Dysphagia
Dysphagia can occur due to various underlying medical conditions or as a result of certain factors. Some of the common symptoms and conditions associated with dysphagia include:
– Trouble swallowing solid foods or liquids
– Feeling of food getting stuck in the throat or chest
– Pain or discomfort while swallowing
– Coughing or choking during or after swallowing
– Medical conditions like stroke, head and neck cancer, or head injury
– Decreased saliva production, leading to dry mouth
– Neurological disorders such as Parkinson’s disease
– Muscular dystrophies
– Esophageal obstruction or narrowing
If you’re experiencing any of these symptoms, it’s important to consult with your healthcare provider, who may recommend a FEES test to assess your swallowing function.
Comparison to Other Tests and Advantages of FEES
There are various tests used to diagnose dysphagia, including the modified barium swallow study (MBSS) and fluoroscopy. While these tests provide valuable information, they also have limitations.
The MBSS involves swallowing a liquid or food mixed with barium, which allows the swallowing process to be observed using X-rays. However, this approach exposes patients to radiation and may not capture all aspects of swallowing function.
In contrast, FEES uses a fiberoptic endoscope, which does not involve radiation and provides a direct view of the swallowing process. Additionally, FEES can be conducted in an office or clinic setting, without the need for hospital or radiology department resources.
This makes it a more accessible and cost-effective option for patients. Conclusion:
In conclusion, the fiberoptic endoscopic evaluation of swallowing (FEES) test is a valuable diagnostic procedure for assessing and diagnosing dysphagia.
By visualizing the various components and stages of swallowing, FEES enables speech-language pathologists to identify abnormalities or dysfunctions that may contribute to swallowing difficulties. This information helps guide treatment plans and promotes safer swallowing.
If you’re experiencing symptoms of dysphagia, it’s important to consult with a healthcare provider who may recommend a FEES test to evaluate your swallowing function.
