Understanding the Differences Between FEES and MBSS

As we all know, swallowing is an important function that allows us to consume food and drink. However, some individuals may experience difficulties with swallowing due to various medical conditions. For proper diagnosis and treatment, speech pathologists use different methods to evaluate swallowing function. Two common methods are the Fiberoptic Endoscopic Evaluation of Swallow (FEES) and Modified Barium Swallow Study (MBSS). While both techniques are used in the assessment of swallowing, they have distinct differences. Understanding these differences is essential to ensure that patients receive the appropriate diagnostic test and treatment plan. In this article, we will explore the variations between FEES and MBSS, including their procedures, benefits, and drawbacks. So, let's dive in and gain a better understanding of these two essential diagnostic tools.

Overview of diagnostic tests - FEES and MBSS FEES and MBSS are both diagnostic tests used to evaluate swallowing function. These tests are typically used when a patient is experiencing difficulty swallowing or has a history of dysphagia. FEES is a non-invasive test that involves the use of a flexible endoscope to visualize the patient's swallowing function. MBSS, on the other hand, is a radiologic test that uses barium to evaluate the patient's swallowing function. Both tests have their advantages and disadvantages, and the choice of test depends on the patient's individual needs.

What is FEES? FEES is a diagnostic test that involves the use of a flexible endoscope to visualize the patient's swallowing function. The endoscope is inserted through the patient's nose and into the throat, allowing the speech pathologist to observe the patient's swallowing function in real-time. FEES is a non-invasive procedure that can be performed in various settings and does not require the use of radiation.

FEES can provide valuable information about the patient's swallowing function, including the presence of pharyngeal residue, laryngeal penetration, and aspiration. This information can be used to develop an appropriate treatment plan for the patient. FEES is also useful for evaluating the effectiveness of therapy and monitoring the patient's progress.

How is FEES performed?

The patient is asked to sit upright, either at bedside or in a chair. The speech pathologist then inserts the endoscope through the patient's nose and into the throat. The patient is asked to swallow different foods and liquids while the speech pathologist observes the swallowing function through the endoscope. The procedure takes approximately 15-30 minutes to complete.

Advantages and disadvantages of FEES One of the primary advantages of FEES is that it is a non-invasive procedure that does not use radiation. This makes it a safe and effective diagnostic tool for evaluating swallowing function. FEES can also be performed in an outpatient or home health setting, making it more convenient for patients.

However, one of the disadvantages of FEES is that it can be uncomfortable for some patients. The insertion of the endoscope through the nasal passages can cause discomfort and irritation.

What is MBSS? MBSS is a diagnostic test that uses barium to evaluate the patient's swallowing function. During the test, the patient is asked to swallow different foods and liquids that have been mixed with barium. The barium allows the speech pathologist to observe the patient's swallowing function using X-ray technology.

How is MBSS performed?

MBSS is typically performed in a radiology department. The patient is asked to sit in front of an X-ray machine, and a radiologist or speech pathologist administers the test. The patient is asked to swallow different foods and liquids that have been mixed with barium, and the healthcare professional observes the swallowing function using X-ray technology.

Advantages and disadvantages of MBSS One of the primary advantages of MBSS is that it provides detailed information about the patient's swallowing function. The use of barium allows the speech pathologist to observe the patient's swallowing function in real-time using X-ray technology. This information can be used to develop an appropriate treatment plan for the patient.

However, one of the disadvantages of MBSS is that it exposes the patient to radiation. Additionally, MBSS can be time-consuming and may require the patient to travel to a radiology department or clinic.

Comparison between FEES and MBSS FEES and MBSS are both valuable diagnostic tools for evaluating swallowing function. However, they have distinct differences that make them more appropriate for certain patients. FEES is a non-invasive procedure that does not use radiation, making it a safe and effective diagnostic tool for evaluating swallowing function. FEES can also be performed in an outpatient or home health setting, making it more convenient for patients.

MBSS, on the other hand, provides detailed information about the patient's swallowing function. The use of barium allows the healthcare professional to observe the patient's swallowing function in real-time using X-ray technology. This information can be used to develop an appropriate treatment plan for the patient. However, MBSS exposes the patient to radiation, and the test can be time-consuming.

Ultimately, the choice of diagnostic test depends on the patient's individual needs. In some cases, a combination of FEES and MBSS may be necessary to fully evaluate the patient's swallowing function.

Which test is right for you? If you are experiencing difficulty swallowing or have a history of dysphagia, it is important to speak with your healthcare professional about your options for diagnostic testing. Your healthcare professional can help you determine which test is right for you based on your individual needs.

Conclusion FEES and MBSS are both valuable diagnostic tools for evaluating swallowing function. Understanding the differences between these two tests is essential to ensure that patients receive the appropriate diagnostic test and treatment plan. FEES is a non-invasive procedure that does not use radiation, making it a safe and effective diagnostic tool for evaluating swallowing function. MBSS provides detailed information about the patient's swallowing function but exposes the patient to radiation. Ultimately, the choice of diagnostic test depends on the patient's individual needs.
