"Laryngeal nerve palsy usually refers to the palsy of the recurrent largyngeal nerve. The recurrent laryngeal nerve is responsible for both abduction (opening) and adduction (closing) of the vocal fold. Therefore recurrent laryngeal nerve palsy is also called vocal cord paralysis and may be the first presentation of severe pathology such as cancer. People often present with hoarseness, coughing and exertional dyspnea.
The vagus nerve runs a complex course. The vagus nerve exits the brainstem and descends and supplies and innervates many organs including the heart, lungs and gastrointestinal tract. The right and left vagus nerve descends along the trachea behind the common carotid artery. As the vagus nerve descends down it gives off a few branches; the superior laryngeal nerve which branches into the external and internal laryngeal nerves. The external laryngeal nerve supplies the cricothyroid muscle, the tuning fork of the larynx, responsible for raising pitch.The internal laryngeal nerve is responsible for sensation of the larynx above the vocal cords."

This is hands down THE BEST video I've seen on this subject! Well done!
Very clear explanation with simple and effective illustrations! Thanks!
I just found ur channel after I went through a huge MICRO nervous breakdown 😅 .. most of ur RUclipss will help me .. THANK U DOCTOR VERY MUCH ..and if u don't mind can u make a video about oral flora because am confused between those many classifications 😊😊 anyway.. GOD BLESS YOUR LIFE
Amazing work Armando, love it 👍🏻👍🏻
Armando..Thank you very much for making these videos.. Can you please make a video on Primary TB, Secondary TB, Miliary TB and their comparison...Thanks a lot !
Excellent video-the presentation was easy to follow and very helpful.
Such a beautiful and simple explanation on the topic !
We are thankful to all the best u tubers ,,,
Which upload Such help,, videos
Thanks Armondoo
I have never clicked a video so fast! 🔥👍
Your explanation was very authentic and concise
learned and enjoyed a lot, thank you very much
thank you soooooo muuuuchhhh! this is a great video. Love it!
Armando, speaking on the nervous system, have you done any videos on proprioception? It would be interesting to see the structural differences between sensory neurons and which pathways they follow to the brain
Learned beyond my own imagination, thanks for the animation 🙏🏾
Wonderful explanation . It was very useful .
its just wow,sir can u make more videos of ent,it would be of grt help. thanku
Thank you. Thank you so much. Very helpful
Hello sir ur explaination is very nice and easy to understand... Please make vdos on nose and its diseases... Thankyou so much ..love ur explaination
Excellent lecture sir
Great lecture 👍
funny enough, this condition is the reason my gma went to the dr and found out she had lung cancer. her vocal cord paralysis had nothing to do with her cancer, but because of it, we found it. she had about a 10% chance to get rid of the cancer, and she did, at 72! she has been cancer-free for three years, and while the one fold is still paralysed, she's getting a non-surgical procedure done to kind of inflate it so she can have a voice again.
I came here to try to find the name of the procedure, but it wasn't talked about. I learned a lot, so that's okay :)
Very Good Video and explanation
Very good presentation.
I am not a doctor or study stuff like that but i was like how hard could it get?
And here i am quitting after 2 minutes 57 seconds
I like the way of explanation despite the fact that my brain can’t process all this data.

There are several components to learning human anatomy. One resource I found that successfully combines these is the Sebs Study Crammer (check it out on google) without a doubt the no.1 info that I have ever heard of. Check out this interesting website.
excellent channel
I had anaphylaxis Aug 2018. I had a persistent cough for 3.5 years, breathing was a problem exhaling for 3.5 years, I was treated with inhalers, I had 6 episodes of total voice loss lasting between 6 & 15 weeks. I saw a GP who was an ENT in the UK for 30 years. He said I had "repetitive laryngeal nerve paralysis" caused from forced intubation, he didn't know my history of anaphylaxis which put me on life support. I also have a tumour in the 4th ventricle, operated on 5 months after anaphylaxis where I had kidney & respiratory failure. The surgery was a failure, they "dug around as much as we could but due to your anatomy changing, we couldn't locate the lesion. After being referred within the hospital to ENT, went to ED when having trouble breathing, camera showed vocal chords almost permanently closed & not moving when trying to make sound. Steroids is what brought my voice back. The drs in ENT laughed when I told the the paralysis diagnosis, the male dr said "there is no nerve in the voice box." I am truly fed up with these drs, this video certainly demonstrates there are nerves!!! Any idea what I can do?
Hey are you doing better now?
Thank you very much. Very nicely explained
Do you have Globus sensation?
Lots of love♥️♥️from Egypt.
Thank you so much
Very nice video. 👏
Amazing!
really nice video
Thank you
Please do more videos on ent also
Excellent
amazing!!
Finalllllly I understand this point after suffering🫡🔥
Do you have Globus sensation?
Thanks!
Thank you hero
Make videos in laryngeal sensory neuropathy
Please upload more videos on ENT
I have a small doubt now I am having bilateral vocal card parlysis, what are the options to recover my voice
hi Armando do you feel trauma to a rib can cause laryngeal nerve damage?
Thank u💗
Only outgoing nerve activity is addressed. He omits entirely neural laryngeal feeeback, or interactive activity with the auditory system, with which it is intimately involved.
please continue the ENT seris
can you please do more ocular related vids
Can you please explain about treatment sir
Perfect 🥰🤩
what are the etiologiical differences between incomplete unilateral palsy and complete unilateral palsy?
My guess: If base etiology is trauma... less trauma = incomplete, more trauma = complete
My guess: If base etiology is neurodegenerative, early progression = incomplete, later progression = complete
My guess: If base etiology is iatrogenic, then this is similar to more/less trauma argument.
I don't know if i understand the whole video but still can graps few things. TQ... just came here coz doc said my baby has vocal cord palsy with prominent stridor. Don't know what was that....
My daughter had a very traumatic intubation during a full body systemic allergic reaction to nuts. One month later she had a tracheostomy due to continued swelling. She has now had the trach for 1.5 years and each time she’s had surgery to remove it, they have failed. She is unable to speak or breathe without the trach. Doctors are baffled and we are not sure of our next steps. She’s 22 and otherwise healthy. Any advice?
Can you make a video on cataract?
love you bro
My right side of vocal code is palsy due to nerves compressing by Chester or like tumer last 3 years. My voice is not clear. What can I do please
Sir I have one doubt...in complete paralysis, the cricothyroid muscle is good and it could do the adduction right???so phonation doesn't affect??
Very informative, i have detected left side larynx palsy. .hoarse voice.can't speak clear. ..what to do. .ENT Doctor prescribed speech therapy. .please help
Ap Hakeem Hafiz Abdullah khan se Contect Karen q ki Bhai me bhi thik hua hun aur me apko Hakeem sb ka no deta hun 9508766920
Is there a way you can make more videos specifically going into more detail about superior laryngeal nerve injuries? I was suppose to have a benign ventricular vocal cyst removed while intubated but when I woke up I was told that it wasn't a cyst after all and that nothing was done but all of a sudden I had decreased pitch and can't sing or play with my daughter much anymore. Even in my medical record he put that I seen him for strain and decreased pitch, I never had decreased pitch. I was intentionally set up and profiled as a patient and I'm pretty sure he cut my superior laryngeal nerves because no other otolaryngologists in my area wants to see me based on how I sustained my problem either which makes me suspect it even more. The other doctors I have seen out of state have also been unable to help me and have even fired me as a patient for no reason so to me it is crystal clear that something very wrong has occured. The whole medical field is trying to cover this up so I can't even see a doctor who's willing to find, diagnose and treat my condition but this seems to be the only one that would make perfect sense because I don't have any lesions on my cords ect. They are healthy and come together in the midline when speaking but when I go up in range and pitch they start to seperated and a muscle tension of the false folds is seen more than likely pointing to compensation of a neurologic injury.
Its been a year since this comment? How has the nerve healed?
@@yxvm it hasn't one bit because I was intentionally injured over racial bias. The nerves were chopped on each side from the inside and then the wounds were sutured and I was framed. No investigations either because everything is so corrupt here. The Dr's name is Jason Mudd located in Albuquerque NM.
@@anthonyquevedo474 my laryngeal nerve is messed up. Which caused my left vocal cord not to work. I cannot eat or sip water. I'm on a feeding tube on my stomach. What about you?
@@yxvm if it's just 1 vocal cord and not both there is lots of hope for you. Not sure why you are hooked to a feeding tube but all that you likely need is an implant or injection laryngoplasty to push your left vocal cord to the midline.
In my case, my recurrent laryngeal nerves are intact but both of my superior laryngeal nerves on each side are chopped so this means that I can speak but I am completely monotone and cannot express verbal emotions or sing ect. I can only talk in 1 tone and it's monotone and I cannot yell either. There is no treatment because I was intentionally injured and it was a crime so in order to save this doctor's career they are pretending that I'm not injured at all and I'm just trying to get a lawsuit ect. Injuries like this are so much worse when there is injustice like this involved and you have a responsibility like raising a 2 year old child that depends on you to learn how to speak and develop. This has left my daughter so depressed with delayed speech.
@@anthonyquevedo474 No lawyer will help you? What would it take for a lawyer to take your case?
"The most logical reason for this design is that it is due to developmental constraints. Embryologist Professor Erich Blechschmidt wrote that the recurrent laryngeal nerve’s seemingly poor design in adults is due to the “necessary consequences of developmental dynamics and are not to be interpreted … as historical carryovers” from evolution. Human-designed devices, such as radios and computers, do not need to function until their assembly is complete. By contrast, living organisms must function to a high degree in order to thrive during every developmental stage...". @t. put this in references please.
414 videos in this series... how was it humanly possible to create them all?
Can an injury to the LRRN can use globus sensation?
My son swallowed a battery which caused him Tracheoesophageal fistula. He underwent a large number of operations. A tracheostomy was performed because the vocal cords did not work. Two years ago and it still doesn't work I will undergo a filler operation, but the cure rate is not guaranteed. Will it remain like this?
What about its treatment?
Difficulty breathing I right vocalcard paralysed change my body position what recovery tips
Love you
Does the incomplete unilateral/bilateral palsy always have to be the abductors or is it just an example???
One year later answer: as I know only abductors
Charite 2008-.... 👍
i have paralyzed vocal cords since i was 10 or 11 months old. i am now 37 years old and my vocal cords are still paralyzed to this day. people who don't know me often ask me if I'm sick,have a bad cold. because my voice is very soft,raspy and horse. i can scream like other women can.. like at all. even if i tried i can't at all! so i don't know what its like to scream. i sound normal to me in my head but to others I'm soft spoken,raspy and horse sounding.
Do you have difficulty swallowing ?

Thanks Sir......💚💛💚💛💚💛💚💛💚💛💚💛💙🧡💙🧡💙🧡💙🧡💙🧡💙🧡💙🧡💜🧡💛💚💙
please answer my comment, what would it mean if your laynx continually clicks, it does it all day every day since Pfizer and i cant find an answer
I'll provide an effective and painless way to learn or review anatomy and physiology, from the chemical level through the entire organism
