I am post graduate resident with all Usmle steps cleared , but I admit that today I grasped the clear concept with clarity through this video . Just beautifully explained
An exceptional explanation of this topic! Explained perfectly without any superfluous information. Will send all of my medical students and residents to this video!
Excellent clear explanation! I've been looking at so many different sources to understand this and your explanation was so clear, didn't even have to pause the video. Thank you so much.
One November morning when I woke up I felt like hundreds of stings on my face and it was hurting so much. I went to hospital and one Doctor named Dr. Mike examined me and told me that I have got Bells Palsy and I was shuttered to tears after listening to this. As I have heard it takes a lot time to recover from this. Also, sometimes we have to undergo for the surgery. So, I started taking allopathic treatment and nothing seems to work. But One day I watched an article of Dr. Vikram sir from Planet Ayurveda and decided to go there for my treatment. I started taking treatment and got very amazing results. Thank you Dr. Vikram sir for giving back my smile and I am very thankful to you.
1. Infranuclear of left facial nerve 2. Supranuclear lesion of left facial nerve 3. Infranuclear lesion of right facial nerve 4. Supranuclear lesion of right facial nerve
I found as an ER Dr the easiest way to Dx Bells Palsy when findings were VERY subtle and forehead not affected (yet) that the most reliable way was to watch the eyes blink. the affected eye does NOT fully close with blinking = Bells.
@@mamunurrashid3141 it is little confusing and wrong diagram 2 and 4 are upper motor neuron lesions so both eyebrows should be up and 2nd is left side UMNL , because UMNL is always contralateral so here both eyebrows should be up and not able to smile on right side
Thank you, very well explained. If you get a bilateral facial nerve palsy (it happens!), you'll be thinking about Guillain Barre syndrome, sarcoidosis and Melkersson-Rokenthal syndrome.
Shouldn't the UMN examples be half a face is fully expressing, but the affected side has eyebrow up too. so it should be 2 eyebrows up on the UMN cases. ? This is a trick bc in all UMN lesions the other UMN can innervate the brow, so ALL 'intact' sides of the face should be able to raise eyebrow. 2+4 have a dead eyebrow on unaffected side, but the un-lesioned UMN should help raise it, right? Wasn't that the point of the differential. 1. left side is fully numb, with right eyebrow up so UMN is intact, so this is LMN on ipsilateral side (left) 2. right side of face fully numb signaling LMN on R, but with upper of left numb too. why is upper of left face numb? Why can't left ipsilat UMN innervate it. 3. right side of face fully numb, so LMN on ipsilateral R side 4. left side of face fully numb showing LMN on left, but upper side of right is numb. The right side has a lesion not discussed in this video (only numb upper right side of face).
We should remember the difference in the symptoms of UMN and LMN 1. Left lower motor neuron lession due to absence of nasolabial fold and unable to raise his eyebrow 2. Right upper motor neuron lesson coz only absence of nasolabial fold but pt can raise his both eyebrows 3. Right lower motor neuron lesson (vice versa of 1) 4. Left upper motor neuron lesson vice ( vice verse of 2)
2 and 4 are UMNL bcz upper motor has the privilege to give ipsilateral and contralateral suppliment to the face of the upper region. 1 and 3 are LMNL because the eyebrows are affected due to the lesion of the motor in the whole side face.
@@the_scrunchies_studio6952 it would be umnl only as patient is asked to raise their eyebrows and the only way we can check that is by comparing the normal side . Since affected side of patient is right side of face with the right eyebrow being raised as much as if not more than the normal side means that right upper half of face is intact therefore the lesion is left umnl (as umnl is contra lateral to affected side).
@@abidhossain2023 no If it's UMN lesion it will be of contralateral side. In 2 u can clearly see that right side of face is unable to smile so left UMN palsy is the ans for 2. Vice versa for 4.

Such great content. Very very simplified and easy to understand. The only video explaining this topic under 10 mins
The only video which could clear my doubt. Thank you!
Admit, that i cleared this concept in a better way today. Salute to u sir.. Very well explained❤
Bestest teacher in world💯💯💯💯
I was struggling for long time wanting to learn this topic but u solve the prob. Within few minute... Salute to u sir
Thanks alot for saving my life ...may you live long...such a easy explanation 😭

2 is LMN lesion
It's wrong @@Medinaz
Thanks sir for explaining the concept in a very nice way ❤

Your video finally cleared my concept which I didn't understand from many times
This video is very much effective & easier. Thanks a lot ❤
In love with this channel.. ❤
Literally very well explained 🎉❤ finally it is understandable
Probably the best video explaining VII palsy! Tysm
LMN - Lt. side
UMN - Rt. Side
LMN - Rt. Side
UMN - Lt. Side
Concept is cleared 😊
You r wrong sis...
2 & 4 r wrong.
UMN lesion means contralateral lower half paralysis.. and in the image 2 & 4 consider both eyebrows are raised...
I found as an ER Dr the easiest way to Dx Bells Palsy when findings were VERY subtle and forehead not affected (yet) that the most reliable way was to watch the eyes blink. the affected eye does NOT fully close with blinking = Bells.
This finding in both umn and lmn???
1.LMNL (Left)
2.UMNL (Left)
3.LMNL (Right)
4.UMNL (Right)
Mostly people are confused in 2&4 so its UMNL it is contralateral means on opposite side.
same
you are wrong
@@drjayverma9235she/ he is correct
But why eyebrows are not raised?
@@yashichaturvedi9812bcz of paralysis to frontalis part of occipitofrontalis supplied by facial nerve!

Tq soo much for ur very simplified and awesome explination sir👏👏👏👏👏👏👏
My pleasure
thanks only u made me this clear
Suffered from this concept since 5 years ❤
Glad to know that. Thank you
Do you have headaches duo to that?
Lol
this is the best explanation I've seen to any topic in my med school history
such a life saver! I was cramming at the last moment,this video helped to understand the concept in short time..
iv been watching all the videos about facial nerve and only this one could explain to me what i needed to know
1. Left LMNL
2. Left UMNL
3. Right LMNL
4. Right UMNL
PS: Considering both eyebrows raised in 2 and 4.
1. Left lmnl
2. Right umnl
3. Right lmnl
4. Left umnl
2 lt or rt ?
Please explain.

What an explanation! Thank you so much sir.

Thank u Allah bless you very well understand on your concept
Shouldn't the UMN examples be half a face is fully expressing, but the affected side has eyebrow up too. so it should be 2 eyebrows up on the UMN cases.

1. left side is fully numb, with right eyebrow up so UMN is intact, so this is LMN on ipsilateral side (left)
2. right side of face fully numb signaling LMN on R, but with upper of left numb too. why is upper of left face numb? Why can't left ipsilat UMN innervate it.
3. right side of face fully numb, so LMN on ipsilateral R side
4. left side of face fully numb showing LMN on left, but upper side of right is numb. The right side has a lesion not discussed in this video (only numb upper right side of face).
This is the best explanation for this topic…thanks a ton!
1- Lft LMNL
2- Lft UMNL
3- Rt LMNL
4- Rt UMNL
Bosss❤
Art of presentation ♥️
This video was extremely helpful
Thank you!!
Glad it was helpful!
@@Medinaz can bellspalsy affect your neck?
Stay bless sir...haven't seen such illustrated information on this topic
Best explanation ever❤
Please consider that in case of "2" and "4" both eyebrows are raised.
What is the correct answer
So there is no difference between case 2 and 3 ? Cause they have the same findings
Medinaz
So the answer will be?
1- Lt LMNL
2- Lt UMNL
3- Rt LMNL
4- Rt UMNL
Ok, perfect! I was confused at first.
1.left LMN
2.left UMN
3.Right LMN
4.Right UMN
Thanks for the crystal clear explanation
We should remember the difference in the symptoms of UMN and LMN
1. Left lower motor neuron lession due to absence of nasolabial fold and unable to raise his eyebrow
2. Right upper motor neuron lesson coz only absence of nasolabial fold but pt can raise his both eyebrows
3. Right lower motor neuron lesson (vice versa of 1)
4. Left upper motor neuron lesson vice ( vice verse of 2)
1. Right LMNL. 2. Left UMNL. 3. Left LMNL. 4. Right UMNL
Shouldn’t option 2 and 4 be switched as the sign is always named by the side of the sign and not the side of the lesion?
I think lesions should be on contralateral sides
1.left sided LMN palsy
2.left sided umn palsy
3.rt sided LMN palsy
4.rt sided Umn palsy
If 2 is left sided umn palsy them why he is unable to raise eyebrows on both sides as he was asked to do
1- Left LMN
2- left UMN
3- Right LMN
4- Right UMN
Shouldn't 4 and 2 be LMN since the patient is not raising their eyebrows
@@Tumi_2000 i think the same but majority are different

Very much useful sir 👍🙂... Thank you
Most explanatory video 😊
thank you, now I understand! I needed this graph.
1st = Left LMN lesion
2nd = Left UMN lesion
3rd = Right LMN lesion
4rth = Right UMN lesion
Please say, if I'm correct or not,
1. Left sided LMNL
2. Left sided UMNL
3. Right sided LMNL
4. Right sided UMNL
Please correct if wrong 🙏
9/11/23 ... You're correct my past self ! Glad you passed Final MBBS
Thanks
But you didn’t mention that affected side get flappy cause the unaffected side pull the muscle.
1.LMN lesion(L)
2.UMN lesion (R)
3.LMN lesion(L)
4.UMN lesion(R
3 should be lml for right side na ?
1) Left side LMN lesion
2) Left side UMN lesion
3) Right side LMN lesion
4) Right side UMN lesion
@@the_scrunchies_studio6952 He’s correct because the UMN lesion is contralateral
@@thegamersminds392 No. UMN lesion is contralateral

Please tell answer
Such a simple and best explanation 💯
1 LMN of left
2 UMN of right
3 LMN of right
4 LMN of left cz the non affected side will pull muscles towards itself so the side will be opposite
Thank you for good explanation ☺️
I might cry! Thanks alot
Super easy explanation 👍👍👍
Sir , ye toh magic hai ✨😍
Amazing amazing concept! I cannot find this anywhere
Fantastic and really simplified. Good job.
have gotten it at last. Thanks Sir
excellent sir very very thanks to you never understand earlier
Wow what a great video ❤
Excellent, keep the good job going
Thank you so much for your help 🙂
Thank you
Really great explanation, Thanks a bunch
your video is so helpful😍
but there is a que.. if there is both sided UMNL feature will resemble to LMNL or not?
Your question is quite intrigue, since the ipsilateral innervations are affected due to the both sides involvement, then yes it will mimic LMNL
Very helpful explanation, thanks.
2 and 4 are UMNL bcz upper motor has the privilege to give ipsilateral and contralateral suppliment to the face of the upper region. 1 and 3 are LMNL because the eyebrows are affected due to the lesion of the motor in the whole side face.
Can u plz explain me for 2nd like it should be lmn for right na
@@the_scrunchies_studio6952 it would be umnl only as patient is asked to raise their eyebrows and the only way we can check that is by comparing the normal side .

Such a helpful video, Thank you!
Which side of face should raise when paralysis is in the left side of face
Right side
That was explained very well !
1.LMN on left side
2..UMN on left side
3.LMN on right side
4.UMN on right side
2 left or right ???
Please explain.
Thank you it was so easy after this video

@@abidhossain2023 no
If it's UMN lesion it will be of contralateral side.
In 2 u can clearly see that right side of face is unable to smile so left UMN palsy is the ans for 2.
Vice versa for 4.
@@MrYashwantt e
What is fascial palsy than I can't understand the difference between these two condition 🥺
1 and 4 has ipsilateral lower moter lesion .and also 2nd but 3rd upper moter neuron lesion contralateral side
Which side of face is affected in bells palsy?
1.Left LMN
2. Left UMN
3. Rt LMN
4.Rt UMN
All upper motor neuron lesion will cause spastic paralysis while LMN lesion will cause flaccid paralysis right sir ?
