What is the zygomatic buttress?
the structural pillar of the mid-face that extends superiorly from the maxillary ridge through the zygomatic bone to the frontal and temporal bones.
What are facial buttresses?
Bony Buttresses of the Facial Skeleton These buttresses define the vertical height of the face and provide the bony support required for mastication. Masticatory forces imparted to the midface are transferred to the skull base through the ZM, NM and PM buttresses.
What is buttress anatomy?
(lip’ō-oks’ĭ-jen-ās), A structure placed against the base of another to support or stabilize it.
How long does it take for a facial fracture to heal?
They will heal themselves over 3-6 weeks. want to bring the broken bones back into a normal alignment (called ‘reducing’ the fracture) and keep it/them in this place (called ‘fixing the fracture’), preventing further injury. Sometimes they will need to operate to do this.
How many facial buttresses are there?
Anatomy of the Facial Buttresses There are three paired vertical and three transverse buttresses (Figure 1).
What is Le Fort 4 fracture?
Le Fort I level fractures are essentially a separation of the hard palate from the upper maxilla due to a transverse fracture running through the maxilla and pterygoid plates at a level just above the floor of the nose.
What are zygomatic fractures of the facial skeleton?
Zygomatic fractures are the second most common fractures of the facial skeleton, after nasal bone fractures. Due to its uniqueness, the malar bone plays a very important role in maintaining appropriate facial contours. Zygomatic fractures can cause ocular and mandibular functional impairment, along with cosmetic defects.
What is the pathophysiology of zygomatic fracture with asymetry?
All fractures of the zygoma potentiallyinvolve the orbital floor. Minor discrepancies of zygomatic boneposition can cause marked asymetry. The zygomatic bone transmits 3 nerves
What is the intraoral approach to zygomatic fracture treatment?
The intraoral approach to zygomatic fracture treatment was introduced by Keen in 1909. This technique allows both an adequate visualization of the zygomaticomaxillary buttress and intraoral reduction of zygomatic arch fractures. Similar techniques have been published over the last 30 years.
What is the function of the zygomatic bone?
The zygomatic bone plays a critical role in maintaining normal facial esthetics and function. It also plays an important role in protecting the eyes. Rarely is the malar bone alone involved in fractures. Its articulating surfaces (with the maxilla, temporal, frontal, and sphenoid bones) are typically also involved.
