Surgical Advancements of the Maxilla and Mandible

3D animation visualizing the anatomy of the human skull and demonstrating advancements in surgery involving the mandible and maxilla. During this surgery, a reciprocating saw making axial cuts and a curved pterygoid chisel used in an inferior and medial direction are utilized detach the maxilla from the upper portion of the skull. The surgeon then used their thumbs to free the maxilla and advance it forward. The maxilla is stabilized with multiple fixation plates and screws. Next the reciprocating saw is used to perform bilateral split osteotomies on the lower mandible, it is then advanced forward and secured with multiple screws. Lastly, the reciprocating saw is utilized to detach the tip of the mandible, which is advanced forward and also secured with fixation hardware.

[@shekinass]

this is one of the scariest things I've ever seen

[@VeryOnBrend]

I've seen CGI videos of these before, but for some reason the addition of the saw cutting the bone makes it way more intense.

[@TheCoolOwen]

Yikes, I wanted this surgery, but after seeing this...I don’t know!

[@Real_Deal86]

What about nerves? How can damage be avoided?

[@gasIighter]

does the bone forever stay like that or does it heal

[@corunmila]

How far forward are they moved?

[@jamesxu7582]

What happens to the shavings or bone fragments from the sawing process? How are they collected

[@gorn1120]

They likely have active suction next to it, but I am not a jaw surgeon.

[@Carpediem617]

Will the screws be in permanently? And is this to fix open bite and receding chin?

[@scot1913]

yes

[@Jerometk]

What if I want to do the opposite and get a reduction because both are wsy too advanced, like a duck. Is there a name for such a procedure?

[@Hhjhfu247]

Great Just move everything downward to lenghten everything

[@shivkr7559]

Nope it actually shortens the midface, its just a surgical replication of mewing.

[@lpsamyrose]

What would the name of this surgery be called

[@patoloco1000]

surgery from hell

[@psalmsofselah]

I think it's double jaw surgery

[@kimberlyvillanueva25]

The 2nd is a jaw/mandible surgery, the third one is a genioplasty surgery. Not sure the name of the first one, but if both are getting done, a double jaw surgery.

[@danielleholland2143]

Le fort 1 on the maxilla, BSSO on the mandible, and genioplasty on the chin.

[@yelaminikeen5707]

Do the ever remove those things?

[@cyn5557]

The screws stay in permanently unless you request them to be removed and that would be another surgery

[@sapitron]

it's just a flesh wound

[@Freshly220]

Sweet Jesus 😧

[@xen2807]

horrific

[@tp_mcvey9879]
