I am a radiologist, i loved this video and i think you are the best anatomy teacher of the internet. I wish you did this same video but with a bone reconstruction CT scan. The one you are using is a soft tissue reconstruction, useful for assessing the brain in this case but the price you pay is very low quality imaging of the bone. With bone reconstruction CT for the sinuses you can see every individual air cell of the ethmoid and how they connect with each other, every foramina, every little suture! You would love it. Check out the radiopedia article about paranasal sinuses and look at the case examples with bone reconstruction I wish you someday do CT / MR anatomy videos, or even a course! You would show peaople another prespective that is very useful for understanding 3D anatomy, and you be a blessing for all the radiologists. I encourage you to try and do it, and see how radiologists all over the globe become your fans!! Much of us would greatly benefit from the deep understanding of anatomy you provide.
Are you kidding me?! You shining the light through the bone just showed me that I'm not insane. I recently suffered a cerebrospinal fluid leak which caused intercranial hypotension and we are now in the beginning stages of trying to find the leaks location and whether it's cranial or spinal. Seeing just how sheer the facial bones are blew my mind. I'm having rhinorrhea (post nasal drip right at the back of the throat) which could also be linked. I'm just now worrying about just how delicate these bones are and how nuanced it must be to try to find leaks location/fissure with imaging. Thank you for this video, very insightful. Wish me luck trying to find my leak!
@@edwardturitwenka6115 We came to the conclusion that it's autonomic rhinorrea caused by low csf pressure from a spinal csf leak. The low pressure makes the brain sag downwards, its increased weight then puts pressure on the cranial nerves and can cause lots of strange symptoms. It is just a coincidence that both cranial and spinal csf leaks can cause a clear fluid to run from the nose. I had the fluid tested and it was negative for Beta 2 transferrin so it wasn't CSF.
thank you so much it's so useful and it's clearer now ! can you please talk about other anatomic structures on cerebral CT scan and also MRI ?? you made me love and understand anatomy and it helps a lot in understanding pathology and symptoms , thank you so much !!!!!!
@samwebster You did an amazing job, breaking these down. Question that I would have loved to ask if I was sitting in your class... as far as the sphenoid and ethmoidal cavities, where would a ballon sinuplasty would be most likely to be done? Also, it would be helpful to see how they all connect to each other. Or do they?
Good job But not much information Dr.) CT is a great modality to show ostium of sinuses, osteomeatal complex and other things you can't visualisate in models
Hello greetings question: 1) What could be the possible diagnosis for the symptom of a foul odor emanating from one of the nasal openings "nostrils" considering the findings of a CT scan ? 2) Could the presence of mild mucosal thickening in the CT scan, potentially explain the occurrence of a bad odor originating from one of the nasal passages? please ignore if one the questions if not apply of what you see on the CT scan result . in advance thank you IMPRESSION: 1.

Thank you so much To educate people like me who have very basic human anatomy I have question about deviated septum in the nose by birth , Is there any connection with Blood pressure I may be asking stupid question
I wish you do this with every anatomy you will save my ass I should give u half of my salary as a thank u every month since im living alone and I don’t need it other than food

post nasal flow would indicate it is cranial, probably sphenoidal.
Contrasted CT would help

Oh, I really like it when u do this for us , I'm from Iraq 🇮🇶, much respect for you 👏❤
Wish I had u teaching me in college years ago!!
Wow! So cool and I loved you explanations as to why our skull bones are the way they are. Just marvelous and super interesting!
As a radiology resident I don't know how I thank you
The way u explain is awesome 😎😎😎
Love from INDIA❤️❤️❤️
Am a radiology resident.. u make anatomy very easy.. thanka a lot😊
which country?
Dear doctor sam, we need more head and neck ct tutorials
thank you so much it's so useful and it's clearer now ! can you please talk about other anatomic structures on cerebral CT scan and also MRI ?? you made me love and understand anatomy and it helps a lot in understanding pathology and symptoms , thank you so much !!!!!!
Wonderful,,,, lots of respect to your teaching strategy,,, From India🙏
You are my favorite … your student from Saudi Arabia 💚💚💚💚
Amazing !!! Thank you so much for the detailed explanation !!!!
Which laptop are you using man?
It's nice.
Epic teacher! Thank you. Please also do mri axials.
This was very much informative. Please do one for facial fractures too

Really great video. The sinuses might be easier to see if you can get a bony sharp CT head scan.
How can I find a CSF leak in the sphenoid, ethmoid sinuses of cribiform plate?
Good job
But not much information Dr.)
CT is a great modality to show ostium of sinuses, osteomeatal complex and other things you can't visualisate in models
I can't breath properly,I feel a blockage behind my nose, but CT scan doesn't show anything what can that be?
I love youuuuuuuu , U SAVED MY LIFE
We need more from that
Thank you ⚘⚘⚘
Thank you so much doctor
Have you done a video on the reticular activating system? Would be great if you did! Thanks
Thank you Dr...

Thank you for this video!!
it's cool, it's fun = )
It is!:)
He is making it fun for us !!
On its time !!! Thank you🥲🥲🥲🥲💚💚💚💚
Thank you so much
To educate people like me who have very basic human anatomy
I have question about deviated septum in the nose by birth ,
Is there any connection with
Blood pressure
I may be asking stupid question
I've been waiting for it soooo long 🤗
Plz add subtitles to the videos and continue making videos on CT imaging
I have paranasal sinus disease. one doctor said I'm fine it's just sinuses. google search says it's cancer..
thoughts doc?
my mri side paranasal sinus disease
pleaseee do a full head ct explaining !!! please
does someone know what programme or website he is using?
12:37
Well at least we know 1 of the dislikes on this video is from Voldemort
I am a medical student from iran
You are great in anatomy teaching.
What is your university name?
Quality video!!
Thank You So much !
Thank you sir.
👏👏
Nice 👍
I have a sinusitis and always feel pressure from the rear of my eye because whole nasal cavity is filled with mucus😔
What's yours treatment I fell the same
Warm regards from Chiajna
I wish you do this with every anatomy you will save my ass I should give u half of my salary as a thank u every month since im living alone and I don’t need it other than food
thanks boss
You’re radiologist
Dr house
Freaking nasty.
