Principles of Internal Fixation in Maxillofacial Surgery

Abstract

Since past many years management of facial trauma has evolved greatly. To provide stable fixation various plating system have been developed. To reconstruct the chin and mandibles, craniofacial skeleton surgery and midface fractures, the maxillofacial plating system is designed. There are various forms of plates and screws for fixation of maxilla, mandible and midface including fractures of orbit and zygoma. They also involve plates for mandibular reconstruction after tumor resection. Different sizes and shapes of plates are available as per the needs.

Point-of-care computer-assisted design and manufacturing technology and its utility in post-traumatic mandibular reconstruction: An Australian public hospital experience

“…Load-sharing osteosynthesis is the gold standard of management for uncomplicated mandibular fractures; 1 however, in cases of comminuted fractures and atrophic edentulous mandibular fractures, heavy reconstruction plates using load-bearing principles are necessitated and typically are placed via a transcutaneous submandibular approach. 8 A transcutaneous approach offers greatest access and visualisation of the fractured mandible while minimising handling of the mental nerves, allowing access to fix these larger plates on the lower border of the mandible and bicortical screws.…”

“…Application of load-bearing osteosynthesis plates is the current gold-standard management for complex mandibular fractures. 1 Traditionally, this has required a transcutaneous submandibular approach, carrying with it the risk of damage to the facial nerve and obvious extraoral scarring. 2 Previous case reports 3 – 5 describe the use of computer-assisted design and manufacturing (CAD/CAM) technology through external vendors to aid transoral mandibular reconstruction.…”

Finite Element Modeling for Virtual Design to Miniaturize Medical Implants Manufactured of Nanostructured Titanium with Enhanced Mechanical Performance

“…For the case of the maxillofacial plate, several types of boundary conditions and loads were investigated, since different variations in fixation methods can be successively used in craniofacial surgery depending on the clinical needs [ 30 ]. The standard testing procedures for the surgery plates suppose relatively simple three-point bending testing technique, which is able to provide only a basic insight into the surgical device strength.…”

Kirschner Wire Fixation Versus Mini Plate Fixation in Multiple Metacarpal Shaft Fractures of Hand to Compare Early Range of Motion in Hand

“…Another advantage of mini plate fixation is that it can be used to treat more complex fractures, including comminuted fractures, fractures with significant displacement, and fractures that require multiple fixation points. The plates and screws used in mini plate fixation are made of strong, biocompatible materials that can remain in the body for extended periods of time without causing adverse reactions [21][22] .…”
