I've learned from this video that: - LeFort represented here as having a triangular shape, Because it is a pyramidal fracture, It affects the maxilla, medial orbit, and nasal bone above. There is a complete craniofacial disjunction due to the result of a four-three fracture, and now since both sides of the orbit are involved, the skull has been completely fractured from left to right.
LeFort to fracture is a pyramidal fracture hence why it's shown here as this triangular shape it involves the medial orbit and the nasal bone up here in addition to the maxilla. There is the lee of a four-three fracture which is a complete craniofacial disjunction and now we're involving both sides of the orbit and it's a complete fracture from left to right of the skull. Also there is the zygomatic au maxillary complex fracture formerly known as a tripod fracture it was called a tripod fracture because it involved three fracture lines one at the lateral orbit one at the maxilla and one at the zygoma.
At the time of trauma as you explained the Gn fracture is ipsilateral while Condylar farcture is contra lateral but in terms of the shift of the Mandible it is shifted to the same side of the fracture right?
A complete "LeFort I setback" is not a possible option due to physical constraints of the skeleton. A better option would be a segmental setback where you split the maxilla into three pieces and setback the anterior segment.
Hello Dr Ryan. I think this is an interesting topic and I found that bilateral body and parasymphyseal fractures (anterior mandible)can influence upper airway because of the tounge displacement and loss of attachment of genioglossus m. Thank you. Dr K. MPH.
So I have a question. If your jaw goes to the right for example due a fracture. You would think this problem is due fracture is coming from the right side. Right? I’ve seen some people say the opposite and other say what I say..! I’m sorry but I’m getting confused about how we can detect where the problem is coming from..! So I know you give the example 1:32 about fracture but for the board exam if they don’t mention if it is condylar or angle/goneal fracture what would you say...! ? Thanks in advance for your help.
Yes, that is generally correct! A fracture on one side means you compromise jaw function on that side and so your jaw will shift TOWARD that side during function. I’m not sure how to answer your second question, because the board question will have to reference anatomy or show you a radiograph in order to identify what type of fracture it is.
Mental Dental so in the test they will tell me where the fracture is to give the proper answer. ! Great. That makes me feel less anxious. Thanks a lot for responding. For sure I will support your patron account. My test will be in 3 months. I’m using your videos as first source then decks and other things. You explain everything really well. I love you go straight to the main points. Keep up with your work. Thanks a lot for making these great videos. I know a lot dental students are using your videos. You have become very popular in the dental field. 👍
HI Doc ! I'm a colleague and a follower from Italy , I hope everything good. I just saw this video of yours about ortognatic surgery th-cam.com/video/snWs8b3k_2U/w-d-xo.html , that was great but I have a question. Bone distraction means "the process of generating new bone in a gap between two bone segments in response to the application of graduated tensile stress across the bone gap". In all cases of Le Fort I, that of BSSO, Sarpe and MSDO we can speak of bone distraction, or am I wrong? You talked about bone distraction specifically only in the part relating to Sarpe and MSDO, and I was wondering if it was correct to use the term in the other cases.

Doctor ,please include the topic space infections
Totally agree with your regarding lateral ceph being the answer of a board question, but CBCT being the modality most frequently used in practice.

Awesome presentation... very crisp, understandable, and succinct. Thank you Dr. Ryan.
As usual, fantastic videos and knowledge, presented in the most enjoyable way. Please please make a video about space infections :D :D
thanks
Very nice video. Short and informative👍
Ryan plz make a video on Local anesthetics
I have two videos on local anesthetics! Check out my pharmacology series.
Great work Dr. Ryan!
Gracias
Thank you Dr Ryan!!
thank you !
Resolved like a magic ♥️♥️
Thank you Dr
could you please make videos on anatomy? both teeth and H&N for the board? Thanks :)
Plz also cover midface fracture main points and its radiology I have exam soon?
Wow it’s so easy this way. Thanku doc
Thank you 🙂

Nice

It shifts to the same side as the condylar fracture!
In a Class 2 skeletal, due to maxillary excess what would be the treatment of choice? Le fort ?
A complete "LeFort I setback" is not a possible option due to physical constraints of the skeleton. A better option would be a segmental setback where you split the maxilla into three pieces and setback the anterior segment.
Where can I get more info about the duration of imf
Thanks for this video Dr.! I have a question: Fracture on which part of mandible would comprise patient respiration?

Hello! Would a pano still be the best way to evaluate a mandibular fracture?
CBCT would be the best option! But a panoramic would be a good alternative for less cost and radiation dose.
👍🏻👍🏻
