Dysfunction of the Burp Reflex (DBR) 2: The Cricopharyngeus Muscle

Apologies to all who have been awaiting more posts about the dysfunction of the burp (or belch) reflex (DBR). The sad truth is that I didn’t have anything new to write about! However, thanks to a couple of comments left in the previous post about this topic, there is a bit more I can add.

I had previously mentioned that the injection of botulinum toxin, commonly known under the brand name Botox, into the upper oesophageal sphincter was a new therapy to treat DBR (it has already been used for decades to treat other problems). Since my previous DBR post, a reader commented that her daughter had had the procedure done at the Bastian Voice Institute in Illinois, and that it appeared to have been successful. With other readers going for the same procedure at the institute and with the reassurance that they have had a 100% success rate out of 21 patients so far, it prompted me to try and find out more about this procedure.

Don't worry, it's not that scary! The injection is usually given under general anaesthetic.

Botulinum toxin is a powerful neurotoxin produced by Clostridium botulinum bacteria, and one of the most poisonous biological substances known to science. It causes muscle paralysis, which is why it is used for its most well-known application – smoothing facial wrinkles. It does have non-cosmetic uses, including the treatments of overactive bladder, chronic migraine and muscle spasticity and spasms in conditions such as cerebral palsy and multiple sclerosis. Of more interest to DBR sufferers, it is also used to treat upper  oesophageal sphincter dysfunction. It has more conventionally been used to treat difficulty swallowing, or dysphagia, and it is only more recently that the Bastian Voice Institute has used it for DBR.

I was very pleased to find during my Googling that the Bastian Voice Institute has an informative and very sympathetic page about DBR on their brilliantly named “Laryngopedia”. It outlines that a muscle around the upper oesophageal sphincter called the cricopharyngeal muscle is likely responsible for the problem. The cricopharyngeal muscle is normally tense and contracted in order to keep the sphincter closed. Upon swallowing and belching, it relaxes to allow food in or air out. If it is overly tense and doesn’t open in the downward direction the patient will have problems swallowing (antegrade dysfunction). If it doesn’t open to allow movement upwards, then belching can’t occur (retrograde dysfunction). So according to them, what non-burpers are suffering from is retrograde-only cricopharyngeus dysfunction. A bit of a mouthful, but at least it has a more serious name than “can’t burp”!

There is a much more well-known condition called cricopharyngeal spasm, where the muscle becomes very contracted and causes a lump in the throat feeling. Some sufferers say it is like having phlegm in the throat that won’t clear. It’s often caused by stress and anxiety, and in some cases having a diagnosis and knowing it’s not harmful is reassuring enough to make it go away. Could this point to stress-relief and relaxation techniques possibly being helpful in DBR? I don’t think I’ve been able to burp when I’ve been relaxed, but it’s a possible avenue to explore. I did find myself feeling a bit annoyed upon discovering that despite cricopharyngeal spasm being well-documented, people who can’t burp are being so readily dismissed.

You can read more about the cricopharyngeal muscle and see some lovely photos of it in the Bastian Voice Institute’s Laryngopedia. From what the Institute has reported, every DBR patient who has had the botulinum toxin into the muscle has been able to belch afterwards and effectively been cured. This seems to indicate that in DBR cases where there is no known cause (such as oesophageal cancer), an overly tense cricopharyngeal muscle is the problem. They even mention that although they offer repeat injections if the DBR returns, no patients have yet needed one – the injection seems to reset the faulty muscle.

So far it seems that the Bastian Voice Institute is the only place that offers this procedure. If anybody has come across it elsewhere, please let me know and I’ll post an update. If you would like more information on the Bastian Voice Institute or contact details please go to their website. Sadly for those outside of the US, it may be much more difficult to find a provider. Hopefully as more patients go for the treatment and awareness is increased, this will change.

Just to clarify, I’m not affiliated with the Bastian Voice Institute in any way.

  1. THANK YOU! Just made my appointment with Dr. Bastian. I was literally in tears when I read the link about laryngopedia. It completely explains exactly what happens and gives hope for relief after a lifetime of suffering with this disorder. I can’t wait! And I can’t thank you enough for this blog. Flying to Chicago from Florida in April. Will keep you updated on the progress. BTW, Dr. Bastian is in network for our insurance, so we will have a minimal expense of flight, hotel, deductibles, and the cost of the botox itself. Small sacrifice if it is successful.

    1. That’s great to hear, JK! I’m really happy that you’ve found the blog helpful, and hope that you’ll finally get some relief from the condition. Good luck with your appointment and procedure!

      1. How do you find out the info on costs of the procedure? Do I just need to call Dr. Bastian’s office and tell them I need to see him for treatment of DBR? Will they give me the infor to call my insurance to find out all the costs that will be related to this? I’m in Texas so I’d have to fly and get a hotel as well. Thank you for any info!

    2. Hey, were you able to have this procedure? How did it go? I would love to hear from you. I am interested in doing it myself.

      1. Hi Chanel, Yes, I had the procedure done on April 12. It has completely relieved the chest pressure and allowed me to burp — Since botox wears off, I’m still in the wait and see period. Hoping that my burp reflexes have been permanently reset and there will be no more issues in the future.
        Dr. Bastian and the day center surgery were wonderful. I have complete confidence in recommending the evaluation and procedure by Dr. Bastian. Please let me know if you have it and how you’re doing.

  2. Oh my God!!!! Thank you so much for this! I thought I was the only one who suffered from this. My family and friends think its funny. My doctor thinks I’m crazy. Recently the bloating has gotten so bad that it is now causing other medical problems. My stomach fills up so much with air that I can’t eat and yet I’ll have severe hunger pains. I’m miserable. I find that I’m involuntarily yawning excessively to try to release the excess air but only little gurgles come out. I have been unable to burp my whole life. I was also a very colicky baby. I have to be very careful about which foods and drinks I eat and I can forget about having anything carbonated! I am seeing a GI specialist this coming Wednesday so that is what promoted me to do some research on the internet. I had no idea that other people have had this same condition!!! Now at least I feel like I can go to the appointment with some information of my own. I hope they can give me some answers!

    1. I’m glad you found the blog helpful, Karen! I hope you can get some proper answers at your GI appointment. All the best.

  3. Last week I flew to Chicago from Florida to have the botox injections with Dr. Bastian at Bastian Voice Institute. It’s been exactly 9 days since my procedure and I can say emphatically that it was 100% successful. Dr. Bastian is amazing and the surgery center was great. I never had any doubts about having it done because my discomfort from bloating in my chest, pain, and having to gag myself to get relief was so horrible that I would have tried anything. I have total relief from pressure building in my chest, I’ve been able to go out to eat and socialize without fear of ‘getting sick’, I’ve been able to drink beer. I don’t know if the botox will permanently ‘reset’ my burp reflex. Time will tell. Discomfort from the procedure was primarily a sore throat at night. Everything happened exactly as Dr. Bastian described in the “what to expect” talk. I am able to voluntarily burp – but my burps don’t sound like normal burps. Who cares? It’s a joy to be able to relieve the pressure. If a time comes when I need to have it done again, I’ll book a flight back to Dr. Bastian. Any questions? I’ll be happy to share.

    1. How long did you have to stay in Illinois for the procedure? I’ll also be flying in from out of state and am not sure how long to book my trip. My husband wants to visit Wrigley while we’re there so how did you feel the days following the procedure? Thanks for any info!

      1. Hi Heather, just saw your questions. Sorry for the delay. On vacation with spotty wifi. I flew up on Monday. Had an easy consult and swallow test in office on Tuesday. Had the procedure on Wednesday, flew home on Thursday. Sore throats primarily at night but nothing really uncomfortable. After the procedure I slept for several hours but afterwards I felt perfectly fine. Swallowing food wasn’t too difficult, eat small amounts for the first few days and follow with sips of water. I had 3 baby burps in succession on the flight home and was so thrilled I wanted to do a happy dance in the aisle. I felt fine after the procedure- you should be able to do anything you want but not drive, drink alcohol or sign legal docs the day of your procedure. Can’t wait to talk to you about it,

        1. JK,
          Did you also have the frog like sounds after eating? My daughter suffers from the loud frog like sounds and inability to burp but, does not have bloating or pain.
          Thanks, bb

          1. Yes. I called them “growls”. But yes. I think it came from gurgling gases in my esophagus that couldn’t get out. i didn’t always have pain and bloating. That started about 10-15 years ago. I’m 63 now.

          2. Hi, Did your daughter have the procedure? I’ve been thinking of her and hoping all went well.

    2. I’m so happy to hear that the procedure worked for you, JK! It’s great that you can finally get some relief from the horrible symptoms.

  4. Wow! I’ve suffered with non burping (very rarely) all my life and people laugh when I say I don’t burp and immediately assume I mean I hold back my burps. If I explain that it just doesn’t happen even if I try that look cynical. I’m so glad I have some information on this now. I’m happy to help with any research too.

  5. For those who have had the procedure done by Dr. Bastian, did you still have gurgling/croaking in the days following the procedure?

  6. This is honestly the best news I’ve heard in my entire life. I’ve had this issue for as long as I can remember and also suffer from anxiety attacks when it gets really bad and I feel like I can’t breathe. Definitely going to contact Dr. Bastian asap. I feel like this will change my life..thank you so much!!

    1. Glad this post was helpful, Britni! All the best with your appointment, and I hope that that will be the end of your DBR woes!
