orif maxillary fracture
You can also apply ice to the face frequently for the first 2-3 days postoperative to decrease swelling and improve comfort. Dissection was carried with scissors from the lateral to medial direction.

A mandibular fracture typically results in intense and immediate swelling which can restrict the movement of the jaw.
. However ORIF has the disadvantages of causing facial swelling gingival numbness decreased facial sensation wound infection etc. A larger L-shaped plate is ideal for the fixation of this fracture. It is estimated that about 10 of all facial fractures are isolated orbital wall fractures the majority of these being the orbital floor and that 30-40 of all facial fractures involve the orbit.
A closed reduction approach using maxillary fixation screws and a mandibular arch bar with light elastic guidance was used to treat a nondisplaced fracture of the left mandibular ramus. In isolated maxillary fractures the stable cranium above and occlusal plate below provide sources of stable fixation. The anatomy of the orbital floor predisposes it to fracture.
This principle while seemingly simple becomes more complex in patients with extensive or panfacial fractures. The physician makes facial incisions through the scalp eyebrow andor lower eyelid. Insert at least two screws on each side of the fracture line in each plate.
LeFortFracture OpenReductionInternalFixation ORIF RigidFixation. No internal fixation is used. This is the most difficult plate to properly adapt in a zygoma fracture.
Nasomaxillary fracture is a specific entity that must be differentiated from nasal bone fracture. Placement of fourth plate Looking through the maxillary vestibular approach the fracture of the zygomaticomaxillary buttress is aligned. The fracture extends from the nasal septum to the lateral pyriform rims travels horizontally above the teeth apices crosses below the zygomaticomaxillary junction and traverses the pterygomaxillary junction to interrupt the.
Pathology The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma. There are four points of fixation of the zygoma Zygomatico maxillary articulation and inferior orbital rim. Retrospective review of 11 consecutive patients and literature review.
Choose and contour the plates. Apply one plate to each zygomaticomaxillary buttress first. Pain and swelling are usually highest at 48-72 hours postoperative.
Incision was made just below the eyelashes on the lower lid on the left side. If bone contact is good and the fracture appears stable additional plates may not be required. In a zygomatic fracture that requires orbital floor reconstruction after exposing the zygoma and orbital floor the zygoma should be disimpacted prior to dissecting herniated orbital soft tissues from the maxillary sinus.
Zygomatico sphenoid articulation in the lateral orbital wall. Open reduction and internal fixation via the intraoral approach with an added infra-orbital approach if needed provides good outcomes. They are the second most common facial bone fracture after nasal bone fractures.
Le Fort I fractures horizontal may result from a force of injury directed low on the maxillary alveolar rim in a downward direction. Zygomaticomaxillary complex ZMC fractures refer to the disruption of 4 buttresses in the malar eminence. An open reduction is an invasive surgical bone realignment as opposed to a closed reduction thats done without surgery or an incision.
Fracture size timing of the reconstruction and biomaterials for reconstructions are all important issues which should be considered in orbital fracture repair. A minimum of two screws should be placed on each side of the fracture. In the process of stabilizing and treating a broken jaw our experienced oral surgeons will also ensure that the proper.
Lay Description Code. Zygomatico frontal articulation and the lateral orbital rim. Fractures of the orbital floor are common.
Open reduction and internal fixation through extraoral approaches were used to fixate the displaced right subcondylar and symphyseal fractures. They can account for 40 of midface fractures. Open reduction internal fixation ORIF is a surgical approach thats used for repairing certain types of bone fractures.
After getting exposure we then went to make the subciliary incision. These fractures can also change the contour of the face and as well as the alignment of the teeth. Treatment of Maxillary Fractures Le Fort ORIF Oral Maxillofacial Surgery.
The debate still is present in deciding on whether to treat an orbital fracture or not. A transoral incision is also made through the maxillary buccal vestibule. In a fracture of this nature the reduction and fixation of the zygoma should be performed first.
Orbital fracture treatment is a controversial issue among maxillofacial and oculoplastic surgeons. The fracture sites are exposed. Fractures in this region involve the dentoalveolar segments and the mandible.
The physician reduces a fracture of the malar complex. After that period pain should continue to decrease and you can use either Tylenol or Ibuprofen for mild-moderate pain. Make sure that the screws below the fracture line avoid the tooth roots.
Fractures were noted along the anterior maxillary sinus as well as the zygomaticomaxillary buttress. These are classified as Le Fort I II or III LeFort I fracture is a horizontal maxillary fracture across the inferior aspect of the maxilla separating the alveolar process containing the maxillary teeth and hard palate from the rest of the maxilla. Fixation of unstable fracture segments to stable structures is the objective of definitive surgical treatment of maxillary fractures.
Surgical treatment for maxillary sinus wall fractures currently requires open reduction and internal fixation ORIF with gingivobuccal incision 6.
