From rigid bone plate fixation to stable dynamic osteosynthesis in mandibular and craniomaxillo-facial surgery: Historical evolution of concepts and technical developments.

J Stomatol Oral Maxillofac Surg 2019 Jan 21. Epub 2019 Jan 21.

Department of Oral and Maxillofacial surgery, hôpital la Peyronnie, CHU, 34070 Montpellier, France.

Historically, extensive observation of limb fracture healing led to a consensus that only complete rigid immobilization could guarantee recovery. This agreement was arrived at because for a long time progress in treatment was driven by clinicians and did not stem from the application of biological research. The clinical approach was based on immobilization of the fracture by rigid osteosynthesis plates and bicortical screws. Read More

Traumatic dislocation of the mandibular condyle into the middle cranial fossa treated by an intraoral approach.

J Formos Med Assoc 2019 Jan 7. Epub 2019 Jan 7.

Department of Dentistry, China Medical University Hospital, China Medical University, Taichung 40402, Taiwan. Electronic address:

Dislocation of the mandibular condyle is one of several consequences of facial trauma that can be anticipated. The condylar neck is inherently weak and likely to fracture at the time of impact before dislocating into the middle cranial fossa. A review of the literature revealed that most cases of dislocation of the mandibular condyle into the middle cranial fossa are treated by open reduction and internal fixation via an extraoral approach or are treated conservatively with closed reduction.
