Laryngomalacia – causes, symptoms, diagnosis, treatment, pathology


“Laryngo” refers to the larynx and “malacia”
refers to a body tissue that is soft, so laryngomalacia is a developmental condition where the larynx
doesn’t form correctly and ends up being soft and floppy. Normally, the epiglottis, a flap of cartilage
located just above the vocal cords, makes a firm arc over the airway. It’s connected to the larynx by cartilaginous
structures called aryepiglottic folds. In children born with laryngomalacia, the
aryepiglottic folds are shorter than normal, so they pull the normally arc-shaped epiglottis
down into a distinctive omega shape. Weak laryngeal muscle tone is thought to cause
the condition, but the exact mechanism isn’t well understood. The cartilaginous tissues are also softer
than normal, so they flop into the airway. That means that when the child breathes, that
floppy structure gets sucked into the airway, causing stridor which is a high-pitched, whistling
sound during breathing. In some cases the obstruction of the airway
can be so bad that it can make breathing difficult. These symptoms are usually present in infants
a few weeks after birth, peaking at around six months, laryngomalacia typically self-corrects
around 12 to 18 months, as the throat muscles strengthen over time. If laryngomalacia is suspected based on the
symptoms, the diagnosis can be made by laryngoscopy or bronchoscopy, using a camera to look down
the throat for the classic omega-shaped epiglottis. Treatment is rarely necessary, but if the
problem persists, it can be resolved surgically. The shortened aryepiglottic folds can be cut,
releasing the constrained omega-shaped epiglottis, restoring it to its proper shape and opening
up the airway. All right, as a quick recap – Laryngomalacia
is a respiratory condition where the cartilaginous tissues of the larynx don’t develop correctly,
leaving it soft and floppy. Shortened aryepiglottic folds pull the softened
epiglottis into an omega shape, obstructing the airflow and causing stridor. Laryngomalacia generally resolves over time,
but if it persists, it can be corrected surgically. Thanks for watching, you

  1. Could you show real pictures of the conditions in future videos? It would have been nice to see what the abnormal epiglottis looked like in real life.

  2. it's good but the info is a little bit inadequate, like how do u diagnose it and the clinical manifestation of it, otherwise everything is cool 🙂

  3. hi professor, this is your first video i just watched.I like it. now i'm gonna subcribe your channel.i hope you can help me alot to become a good doctor.

  4. That was awesome! I wish you guys could do videos like this for Insurance Brokers exam. I got here cause I was trying to self diagnose myself. So now my doctor is telling me that your videos are wrong and I should watch you tube videos and she doesn't want to get me the blood test to prove it. She is saying that it cost a lot I of money to do all these blood work and a waste of Government money to do useless test. Point is I believe your information is absolutely correct and easy to understand and remember. Keep up this amazing work and Thanks for sharing.

  5. I have 2 children ages 3 and 5. They have had to have this procedure done over and over again. They go in to respiratory distress every night needing adrenalin until they have their epiglottis released. For some reason it keeps tightening up and doctors can't give us answers. If this sounds familiar to anyone please reply back, this condition runs our life and we are so scared, we have had their oxygen sats drop as low as 68% and their voices disappear sometimes. The oldest who is 5 says she can breathe in but can't breathe out and we have had 92 hospital admissions in 4 years, many misdiagnosis such as croup and it's really hard to get doctors to believe what is going on because the children present fine other then clearing of the throat, lots of swallowing and they will do this until the attack hits which then has to be resolved with adrenalin. Help

  6. It's the first time i see that person who is helping us every time we feel hopeless of understanding the shit written in our sheets lol 😂😂😂
    Thanks man you're great 💓

  7. Knowing that it can be healed was a like a load off my mind. Thank you so much. My newborn baby suffers from it, I pray he'll be healed as soon as possible

  8. Thank you. Just found out my son has this and a redundant epiglottis. He’s on the breathing tube right now and I’m hoping to get him off without doing a trach.

  9. The Aryepiglottic folds are triangular folds of mucous membrane enclosing ligamentous and muscular fibres. They are located at the entrance of the larynx, extending from the lateral borders of the epiglottis to the arytenoid cartilages.

  10. Hello! I'm from Russia. My child has a mild congenital laryngomalacia. Stridor. Age 4 months. A cough appeared.
