Classification and treatment of zygomatic fractures: a review of 1,025 cases.

Zygomatic complex fractures, zygomatic arch fractures; pp. To avoid confusion, two terms used conventionally in the dental nomenclature merit clarification: Scaphoid Rolando Bennett’s Boxer’s Busch’s.

The search for the ideal fixation of palatal fractures: Outcomes of severely comminuted type III nasoorbitoethmoid fractures. Anterosuperior displacement of the LCM fragment left, multifragmentation of the antral wall left, Infraorbital rim left intact. Ironically enough, it is possible to display midface fracture patterns in the graphics that do not exist in reality.

Although Le Fort and many of his successors e. This will hopefully foster a better understanding of the individual mapping of fractures that is necessary to establish a detailed treatment plan for a patient. The nasal bones are interposed above the nasal aperture between the frontonasal maxillary processes that form the nasal sidewalls and medial orbital rims conjointly. Morphologic characteristics of bony edentulous jaws. From Wikipedia, the free encyclopedia. The formerly used ‘tripod fracture’ refers to these buttresses, but did not also incorporate the posterior relationship of the zygoma to the sphenoid bone at the zygomaticosphenoid suture.

The Comprehensive AOCMF Classification System: Midface Fractures – Level 3 Tutorial

Fracture Coding and Topographical Distribution Fractures of the midface are identified with the two-digit code 92 1 followed by a letter identifying the involved divisions. Li K K, Stephens W. Discussion This level 3 classification for midface fractures intends to build up on and optimize existing schemes.

The cllassification septum encompasses three components: Unilateral fracture of the pterygoid process. Displacement of these fragments can be defined according to the six degrees of freedom by the translation and rotation, or planar and spherical movement of the fragments.

A classification of injuries of the nasal skeleton. W1 lim 2 im. Fractures of the malar-zygomatic compound: NOE reaching into the adjacent regions such as the frontonasal maxilla in association with displacement of the orbital contents, orbital dystopia, or bone loss. Fracture morphology in the central midface is documented by fragmentation, displacement, and bone loss.

Fractures of the palate are classified into one of three categories: Lateral Midface Zygoma The zygoma and its anatomical subregions constitute the lateral midface attached to each side of the maxillary portions of the central midface pyramid in transition to the greater sphenoid wing, the frontal bone, and the temporal bone. The description of the fracture morphology at the lateral and inferior orbital flanges of the zygoma ID 5 and 8 conforms to the precepts and nomenclature allocated to the orbital walls within the level 3 Orbital Fracture Classification.

Advantages of the subcranial approach in cases. Symposium on maxillo-facial trauma.

W1 lim 2 lim. Log in Sign up. Fragmentation is one of the features of fracture morphology.

Displacement can assume extreme proportions with complete loss of contact between minor and even major fragments due to distraction, as exemplified in zygoma and NOE fractures Figs. D ICD – No matter to which of the two classification archetypes is resorted to, attention must be paid to the clinical status of the medial canthal ligament.

The topography of the different midface regions central midface—upper central midface, intermediate central midface, lower central midface—incorporating the naso-orbito-ethmoid region; lateral midface—zygoma and zygomatic arch, palate is subdivided in much greater detail than in level 2 going beyond the Le Fort fracture types and its analogs.

The posterior limit of the zygomatic body is made up by the zygomaticotemporal suture line. The broad category of tooth injuries captured in the proposed system 17 can be broken down into a manifold of subcategories e.

The division line between UCM and ICM coincides with the demarcation between the medial and the inferior orbital rim in the inferomedial quadrant. The purpose of fixation is to restore the normal appearance of the face. Individual teeth or teeth groups are often acronymed: The regions are coded in the order from the patient’s right side to the patient’s left side starting with the zygoma.

Fracture displacement within the zygoma and zygomatic arch can be documented; however, it is not included in the overall code. The zygomaticomaxillary suture is less often separated by a single linear crack but by multiple fragments.

ZMC complex fracture Right zygomaticomaxillary complex fracture with disruption of the lateral orbital wall, orbital floor, zygomatic arch and maxillary sinus.

Author information Copyright and License information Disclaimer. No retrodisplacement of both maxillae, no displacement of the Le Fort I and III fragments left, multifragmentation facial antral wall right, minor amc of frontonasal fragment right. In the anterior maxilla, the vertical dimension of the alveolar ridge distance between the crest and the nasal floor is best assessed in sagittal CT scans. The facial skeleton is composed of multiple singular or paired bones that are articulated by fixed sutures.

Loading Stack – 0 images remaining. The difficulty in developing a standardized instrument for qualifying or, in particular, quantifying displacement in the midface needs apprehension and admittedly requires ongoing efforts in the future because it is resolved here in a rudimentary style only.
