MBSS AND FEES. Why Not Both?


Whenever you read the literature, you often see MBSS vs. FEES or a similar thought comparing the two tests, attempting to find the superior, gold standard assessment.

On social media, we seem to have 2 camps.   Team MBSS and Team FEES.   You can’t be friends and in separate camps!!  (Completely joking here!!!)

Many facilities choose one test or the other.   You can either request MBSS or FEES.  They’ll have a contract for Mobile MBSS or Mobile FEES.   In the hospital, it’s either/or.

What would happen if we try to change that thought.   What if, we changed from an either/or to a both.

What If…….

What if companies had the option of both.  Maybe the ability to do both tests at one time?  Even if they are completed at different times.  Both tests give you such a varied viewpoint of the swallow while often providing the same information regarding the swallow.

The literature says……

The majority of the research tells us that we see the same pharyngeal events with FEES that we see with MBSS including decreased back of tongue control/oral containment resulting in premature posterior loss of bolus, decreased hyolaryngeal excursion, decreased epiglottic introversion, decreased laryngeal closure resulting in penetration/aspiration or vallecular residue.   We may see decreased opening of the Pharyngoesophageal Sement (PES)/Upper Esophageal Sphincter (UES)  resulting in pyriform sinus residue and maybe aspiration.  We can see residue on the posterior pharyngeal wall due to decreased pharyngeal squeeze/stripping wave.

So, in fact, with either test we can see the physiological events of the swallow that lead us into a plan of treatment.

Much of the research states that residue, aspiration, etc are all rated as more severe when using FEES.

What about the doctors

Look at physicians.   they will often order a CT scan for a stroke patient.   When this doesn’t give them all the information needed, they often then order an MRI.   The CT and MRI do give different viewpoints and provide some different information and compliment each other very well.

Anecdotal thoughts.

In my experience, not just reading the research, when a patient had a FEES (performed by me) and later had an MBSS (performed by a colleague) the findings were exactly the same leading to identical recommendations.   In fact, I did not know until after the test that the patient was going to have an MBSS and the other SLP did not know until after the test, the results from the FEES.

Changing our thinking.

So let’s work on changing our thinking to BOTH tests, not just one or the other.  Let’s educate other medical professionals that we are looking for much more than just aspiration or penetration and that we can do so much more than just change a diet.

Let’s make a change!

Modified Barium Swallow Study: Gold Standard or Old News?

The Modified Barium Swallow Study, no matter what name is used, has been considered a gold standard for many years in the assessment of dysphagia.  

Recently there has been a lot of debate about whether the MBSS continues to be the gold standard or if FEES (Flexible Endoscopic Evaluation of Swallowing) has taken the place as the gold standard evaluation.

For some reason, it’s become an either/or world that you only get FEES or you only do MBSS.   This is just absurd!

Both tests can provide valuable information.

The MBSS can give you valuable information (FEES posts coming soon!)  You can visualize the oral cavity as the patient prepares to swallow the bolus.  You can visualize as the bolus passes through the pharynx and hopefully through the esophagus.

You can view the patient laterally, you can use an anterior-posterior view or even an oblique view as needed to gather as much information as possible regarding the swallow.

Communication is key.

As the treating SLP, it is so important to get information to the SLP completing the instrumental assessment regarding patient history, why you are ordering the study and possibly even some information about your tentative treatment plan, current diet level, etc.  Most patients are not able to relay the information the same way an SLP would, if at all.

Are there any strategies you think might be beneficial?

Are there any consistencies you want trialed?  Let the SLP know!!

The SLP completing the MBSS doesn’t quite get off the hook.

As the assessing SLP or the SLP completing the instrumental assessment, it is critical that the treating SLP receive a report they can use to build a treatment plan.  It is impossible to educate a patient on why they are on an altered diet or why they need to use such and such compensation when the SLP is unsure.  The report needs to include compensations trialed and effective or ineffective.  It’s also very difficult to know what consistencies, amounts, etc to use for therapeutic trials if the study was discontinued after one instance of aspiration on a teaspoon of thin.

Remember though, sometimes the report never gets to the treating SLP.   Sometimes they try like crazy to get it, but they are never able to do so.

You won’t get an instrumental assessment if you don’t request it.

Often instrumental assessments are not recommended for a variety of reasons.  Maybe you have sent multiple patients out for an MBSS and the report is not what you need to create a solid treatment protocol.  Maybe the patient refuses or the doctor refuses or the facility refuses.

It is time that we educate physicians, nurses and other medical professionals on the purpose of the MBSS.  Physicians often know or have a good idea that a patient had a stroke.  They still use the CT scan and/or MRI to determine size of stroke, location of stroke and whether the stroke is acute or an old infarct.

We need the same diligence in our field to assess dysphagia beyond just penetration/aspiration and diet selection.  Whether the physician orders the MBSS or the patient participates should be irrelevant to our recommendation for MBSS.  If we believe the MBSS is an important tool to our patient’s care, document and recommend.

The Instrumental Guide to Compensatory Strategies and Maneuvers

When completing instrumental assessments, the easiest way to change the swallow is to change the diet consistency.

Dr. Jeri Logemann (1993) has suggested using compensatory strategies/maneuvers in the following order:

  1. Postural techniques
  2. Sensory techniques
  3. Maneuvers
  4. Diet changes

Remember we can often change the swallow through sensory techniques.   Steele and Miller 2010 concluded:  “Boluses of liquids and solids normally initiate pharyngeal swallowing using multiple modalities, including taste, water, touch, pressure, and possibly temperature to excite several types of sensory fibers of different diameters that innervate the receptors in the oropharyngeal mucosa. It appears that stimulation of a greater number of receptive fields and their individual sensory neurons induces a stronger reflex with greater muscle recruitment and force. ”

So, you know all about MBSS, right? 

You’ve learned the MBSImP, you know all about consistencies, all about compensatory strategies.

What barium should you use?

We are often mixing the same barium used in other studies with food and liquid brought in from the kitchen.

At one point, there was a recipe available to make your own barium cookies.  You can also purchase these.

The thing is, when we use the same barium as used in the more in-depth esophageal tests they coat the structures.   That is what they were designed to do.   Sometimes that is all you can use because it’s all that’s available, but you have to remember there may be residue there, that wouldn’t normally be present.

The best option is to use Varibar, which was designed for the MBSS.  This is the same barium used in the MBSImP.

Which Consistencies Do I Trial?

A Moment in Time

Most people call the Modified Barium Swallow Study (MBSS) a “snapshot in time” or a “moment in time”.

You can’t possibly trial every single consistency the person may eat while under fluoro.  The radiation exposure would get to be ridiculous and the kitchen in your facility may not like you much if you do many modifieds in a week.

So what in the heck should you trial?

Well, if you follow the MBSImP, then you know that there is a standardized set of consistencies to trial (thin, nectar/mildly thick liquid, pureed and solid).  You can add to this if you need.  If you want to add a mixed consistency or need to try honey/moderately thick, then you can add that.

Basically, you want to answer the question, what is the physiology of the swallow?

Somewhere along the line, the MBSS became a test for determining if the patient is aspirating or not and what consistency we need to place the person on (or their diet sentence.)

Don’t forget, you are answering the questions:

  • What does the swallowing physiology look like?
  • How can I change the swallow to make it functional?

You are finding the information to develop that patient’s plan of care to make them as functional with swallowing as possible.

The best thing you can do is to test the consistencies that answer those questions.

Now remember, in the MBSImP course, you learn the nectar (mildly) thick liquids can change the swallowing physiology with increased movement of the pharyngeal structures.   You may recommend the patient stays on regular liquids, however you may use nectar (mildly) thick liquids to exercise the oropharyngeal musculature as an exercise.

Compensatory Techniques

Compensatory techniques are used to alter the swallow, however compensations may not create a lasting effect to the swallow.

Compensatory strategies may be short term or used more long-term, such as with patients with head and neck cancer.

Compensatory strategies can be used to alter posture, timing of the swallow, laryngeal closure.

While most compensatory strategies do not cause long-term effects to the swallowing system, some can be used as exercise to create a lasting effect to swallowing.

Any compensatory strategy should be viewed during instrumental assessment to determine the effectiveness and accuracy of completion.


Supraglottic Swallow

  • To close vocal cords prior to the swallow.
  • Improves coordination of the swallow.  
  • Use when you see aspiration prior to or during the swallow.
  • Use with a delayed pharyngeal swallow.

Logemann recommends 10x/day x5 min with 5-6 swallows each time as exercise.  (Frymark et al 2009)

Super Supraglottic Swallow

  • For early closure at the entrance to the airway.
  • Facilitates timing and extent of laryngeal closure at specific levels of the larynx.
  • Use with penetration/aspiration prior to or during the swallow.
  • Use with a delayed pharyngeal swallow.

Mendelsohn Manevuer

  • To assist in laryngeal elevation.
  • Widens the valleculae.
  • Use for reduced laryngeal elevation.
  • Use for reduced PharyngoEsophageal (PES) opening.
  • Use for discoordianted swallow.

Effortful Swallow

  • Increase strength of the overall swallow.
  • Use with vallecular residue.
  • Use with reduced tongue base retraction.


Chin Tuck

  • Widens valleculae.
  • Helps patient keep bolus in the oral cavity.
  • Narrows airway.
  • Use with oral containment issues (posterior loss of bolus resulting in aspiration).
  • Use with reduced airway closure.
  • Use with vallecular residue.

Head Turn (to weak side)

  • Closes the weak side of the swallow directing the bolus to the stronger side.
  • Use with unilateral pharyngeal paralysis or paresis.

Head Back

  • May assist patients with poor oral control or difficulty propelling the bolus.
  • Pharyngeal phase must be intact.
  • Use with patients with poor anterior-posterior propulsion of bolus such as with glossectomy.

Side Lying

  • To help clear pharyngeal residue by altering gravity.
  • Use with reduced pharyngeal contraction (pharyngeal residue, aspiration after swallow).

Changes in the bolus/Sensory

Texture-give a variety of textures.  Patient may be more successful with a bolus they have to chew.  (Don’t try one texture only!!)

Viscosity-May trial thicker consistencies to determine if there is an effect on the swallow.  (May help you determine if thick liquids could be used therapeutically during sessions, not necessarily for diet changes.)

Temperature-Patients may respond differently with a hot bolus vs. a cold bolus.

Sour-Try different tastes.  Sour has been known to stimulate a faster swallow.  Patients may respond to differing tastes.

Size-Patient may have difficulty with a small bolus vs. a large bolus or vice versa.   Some patients require a larger bolus to trigger the swallow.

Pressure-Patient may respond with a swallow given pressure from the spoon as presenting the bolus.

Diet Consistency Changes:

Remember, diet consistency changes should be considered as a last resort!  Do not immediately trial thickened liquids and change a diet without first trialing other strategies that may allow a patient to safely swallow thin liquids.

For more information on the new standardized diet consistency levels, visit the IDDSI website.

Mobile MBSS

Did you know?  Have you heard?

Instrumental assessments come to you!!

Now, you can schedule mobile FEES AND mobile MBSS.

This cuts down the cost of transport and the various costs of instrumental in the hospital setting.

Do you need Mobile MBSS or FEES at your facility?  Chances are, there’s one in your area.

Do you own a Mobile MBSS or FEES company?  Post a link to your website in the comments!!

Do I Really Not Have Access to Instrumental?

It’s the never-ending soapbox.   I know.  There was probably even an eye-roll at seeing this article.

All.  The.  Time.

Did you get an instrumental?  Well, why not?   You don’t know anything without the instrumental.

Reason Numero Uno

The number one reason, that I’ve seen for not obtaining an instrumental is no access.   The SLP wants an instrumental, but they are either told no by their facility or there is no facility even remotely close enough to send the patient.

There are times that the SLP does not request an instrumental because they already “know” the patient is aspirating.

Learn to Advocate

In the references is a link to a phenomenal guide by Theresa Richard for advocating for an instrumental for your patient.  Please look at that!

Do the Math

Administrators are in the business of business.  They have a facility to maintain and make sure that they stay open so they are always interested in the numbers.

These can be easy enough to obtain with a little hard work.   Look at how many patients are on thickened liquids.   How much does the facility pay for those thickened liquids.   Especially if the facility buys pre-thickened liquids, thickened liquids can cost a facility.

Let’s Look at Rehospitalization

How much is spent on rehospitalization?  This can be a cost also in loss of revenue from the patient not being in your facility.  What is the primary reason for rehospitalization and is it avoidable and something that can be prevented through dysphagia treatment?

Look at the numbers of how many patients  are misdiagnosed.   If you are changing diets at bedside, we may be overdiagnosing up to 70% of the time.   That means a large majority of those assessed at bedside only, may be on thickened liquids for no reason at all!!  This creates unnecessary expense to the facility.

It All Adds Up

When you add the cost of thickened liquids or the cost of rehospitalization vs. the cost of one instrumental assessment, your facility should be able to see the benefit.

Also, if you can show the numbers, that if you are able to obtain a good report and then treat the patient, often these patients can be rehabilitated with more than the usual list of oral motor exercises.

Going Mobile

The other great thing is that instrumental assessments are mobile.  You can often use mobile MBSS or mobile FEES to assess patients at a fraction of the cost of sending the patient to the hospital for the exam.

Do your research, crunch the numbers and be that squeaky wheel to get appropriate care for your patients!

What Good is the MBSS if the Report is Not so Good?

I think we all get it. 

You work in a facility or for a company that has to send patients our for modifieds or instrumentals of any sort.

It’s Never Easy

You go through the works.   You have to evaluate the patient and try to scour through their paperwork to find out if they’ve had an instrumental.   You talk to the nurses and the DON, the DOR, the doctor and have to jump through a million hurdles just to get the patient out for the instrumental.

You sometimes wait for weeks for your patient to be scheduled and then finally get in for the study.

The Wait is Over…..Or Is It?

The patient comes back to your facility and all they can tell you is they had 2 bites of food and 1 drink and they were told to thicken their drinks.

You get the report (if you’re lucky) and find out that your patient aspirated on thin but not nectar thick (mildly thick) but they did penetrate so they are now on pureed food and honey thick liquids.

Your first thought….What the hell!!  Did they try compensatory strategies?  Did they try to change the bolus size?  Did they try anything?

The Report

You don’t know because it’s not in the report.

You may also not know how they responded to the aspiration, when it happened or why it happened.

The report is everything in the Modified Barium Swallow Study (MBSS).  The report is how the treating SLP knows what is happening and how they build the patient’s treatment plan.

What Happens in the Fluoro Room, Goes in the Report

You see, much like the evaluation you write or the plan of care you carefully create and document, the MBSS report has to be thorough and complete.  If it’s not documented, it didn’t happen.

You complete the best MBSS you know how so make it count with a great report.

Dr. Logemann reported on using compensatory strategies, sensory techniques and multiple trials of a bolus to determine swallowing deficits and how to safely keep the patient eating by mouth if possible.

We may use a chin tuck, head back or head turn to change the physiology of the swallow to improve the patient’s ability to swallow a bolus or even a variety of bolus types.

We may use sensory techniques such as pressure on the tongue, change in size of bolus or change in temperature of bolus to change the swallow.

Let’s Be Honest

The fact of the matter is, if we don’t give the patient a chance to swallow in a variety of ways during the instrumental, we may be sentencing them to thickened liquids or altered food consistencies.  We may be sentencing that patient to dissatisfaction, decreased quality of life, dehydration, malnutrition or even pneumonia.

Who Writes the Report

Palmer et al indicated the report includes a summary of what was done (position of the patient, bolus types presented, strategies trialed), a description of significant structural abnormalities, a summary of the observation of swallowing including each functional component, a diagnostic assessment, and recommendations.   Now, keep in mind, Palmer suggested the physician write the bulk of the report, I think we can agree the SLP writes the entire report.

Utilizing the MBSImP report generator can save time and ensure that you are providing a complete report.   Following a protocol and a report generator can ensure that nothing is forgotten, plus, if you can provide the radiologist with the protocol, it can save that surprise when they don’t understand what you are doing with a patient, which can lead to a discussion in front of the patient/family.

How are the reports in your area?  Good, great, need a little work?  How are the reports you write?

What’s In A Name

Seriously, how many names can we have for one test?

We typically do the same thing…..assess swallowing function, so why a million different names?

In the early days, the swallowing assessment using x-ray was called a Cookie Swallow Test.

You can read more about the history of the MBSS:

untitled design-1

The same test is more recently called:

  • Modified Barium Swallow Study (MBSS)
  • Modified Barium Study (MBS)
  • Videofluoroscopic Swallow Study (VFSS)
  • Swallow Study
  • Rehab Swallow Study

No matter what it is called, the procedure should be the same.  A variety of consistencies will be presented with an SLP assessing the swallow.  Compensatory strategies may be trialed (more to come soon), various presentation methods may be trialed, sensory techniques may be trialed.

No matter what the name, the SLP will be assessing the physiology of the swallow so that an accurate treatment plan can be developed.

What other names have you heard that X-Ray swallow study called?
