Midface Fractures Medical Assignment Help

Midface Fractures
Treatment of fractures of the midface can be divided into those fractures that affeci, the occlusal relationship, such as Le Fort I, IC or III fractures, and those fractures that do not necessarily affect the occlusion, such as fractures
of an isolated zygoma, zygomatic arch, or NO[‘ complex.

Suspension ·wiring is sometimes used in addition to direct wiring or bone plating. The purpose of suspension. , wiring is to provide stabilization of fractured bones by suspending them to a more stable bone superiorly. B Suspension wiring techniques include those with wires attached to’ the piriform rim area, infraorbital rims, zygomatte arch, or frontal bone (Fig. 24-29). The suspension wires can be connected directly to the maxillary arch wire, or-they can be connected withan intermediate wire to an interocclusal splint or to the mandible. These.suspension wires prevent movement of the maxilla caused by the inferior pull of the mandible during attempted opening, The use of direct and. suspension wire fixation
docs have significant limitations in many cases, The lirn

ited rigidity of wires may make it difficult fa’ reconstruct and maintain the appropriate anatomic contours, partie- • ularly in concave and convex areas, such as orbital rims and the prominence of the zygoma. Wires may not provide adequate resistance to muscular forces during the entire healing period, eventually resulting in some fracture displacement.
