Perhaps no area of facial trauma has inspired more controversy than the management of mandibular subcondylar fractures. Fractures of the condylar region. Clinically, this equates to open treatment of condylar neck fractures or subcondylar (caudal) fractures (A). The surgeon may elect to place one or two plates.

Panoramic radiograph of a simple mandible fracture of the right mandibular body, minimally displaced. Although closed reduction carries a risk of the bone healing out of position, with consequent alteration of the bite or the creation of facial asymmetry, it does not risk temporary damage to the facial nerve or result in any facial scar that accompanies open reduction.
Other symptoms may include loose teeth teeth on either side of the fracture will feel loose because the fracture is mobilenumbness because the inferior alveolar nerve runs along the jaw and can be compressed by a fracture and trismus difficulty opening the mandinular. This area is superiorly confined to the line passing through the sigmoid notch and anteriorly to the line obliquely connecting the sigmoid notch to the masseter tuberosity 8.
Avulsion fracture Chalkstick fracture Greenstick fracture Open fracture Pathologic fracture Spiral fracture. Cysts and tumours can limit effective bone to bone contact and osteomyelitis or osteonecrosis compromise blood supply to the bone.
The name comes from this injury occurring in soldiers subcondjlar faint on parade grounds and strike the floor with their chin. A leg or wrist, for subcondyllar, has no such structure to help with a closed reduction.
Sign in to customize your interests Sign in to your personal account. Even for lateral dislocations of the subcondylar area, an intraoral approach is suggested, due to the unperceptive scar, no matter how challenging it may be 40 In other projects Wikimedia Commons. Even though early clinical results are seen to be good, complications such as pain, restriction of movement, muscle spasms, mandibular deviation, malocclusion, pathologic alterations of the TMJ, osteonecrosis, facial asymmetry, and ankylosis may be evident later 9 — Author information Article notes Copyright and License information Disclaimer.
Decision making in oral and maxillofacial surgery. A retrospective study from Northern Greece”.
Pointing out the best procedure is certainly not easy assay and many factors influence the matter, so the aim of this review was to summarize the available methods, and their advantages and disadvantages, in order to help make the decision easier. Fractire injuries are often a matter of discussion and controversy among maxillofacial topics 1.

Greenstick fractures are incomplete fractures of flexible bone, and for this reason typically occur only in children.
Transosseous wiring in the treatment of condylar fractures of the mandible. Supplemental maxillomandibular fixation with miniplate osteosynthesis-required or not?
Surgical Management of a Mandible Subcondylar Fracture
Intraorally, if the fracture occurs in the tooth bearing area, a step may seen between the teeth on either side of the fracture or a space can be seen often mistaken for a lost tooth and bleeding from the gingiva in the area.
Following, the AO classification is presented along with a simplified version. The study of conservative treatment of condylar fractures carried out by Zachariades et al.
Mini-retromandibular approach to low subcondylar fractures A Preoperative design of a mini-retromandibular incision. The drain was mahdibular within 3 to 4 days and the stitches removed within 7 days. Evaluation of condylar neck fracture plating techniques. Despite this knowledge, and much debating, authors are subcondylqr unable to agree on an absolute treatment plan for management of condylar fractures.
Black arrow shows the condyle pulled to the medial. The periosteum at the posterior border of the ramus is then incised, and subperiosteal dissection is continued to the condylar area until the fracture line and the displaced or dislocated proximal fragment are identified. Unfortunately no clinical trial large enough is available on this matter to answer these questions. The load for permanent deformation and maximum load of failure were measured in the load displacement curve with the chart recorder Fig.
When the mouth is opened, there may be deviation of the mandible towards the fractured side.
Mandible – Diagnosis – Condylar process and head, simple and complex – AO Surgery Reference
Both closed reduction and the endoscopic surgery had acceptable results. Experimental evaluation of three osteosynthesis devices used for stabilizing condylar fractures of the mandible. Case Report and Literature Review”. It remains uncertain whether plate fixation in condylar neck fractures is rigid enough to dispense with MMF and whether fixation techniques are strong enough to withstand functional loads encountered during the period of bone healing [ 1011 ].
The predominant surgical indication for adults is a dislocated or displaced condylar fracture outside the mandibular fossa, as it is generally impossible to attain anatomic reduction via conservative treatment [ 3 ]. Application of modified retromandibular approach indirectly from the anterior edge of the parotid gland in the surgical treatment of condylar fracture.
Today, for dislocated subcondylar fractures, open approaches are considered the treatment of choice in many surgical units.
The posterior border of the ramus and the mandibular notch serve as reference lines for correct three dimensional repositioning.
Because the coronoid process of the mandible lies deep to many structures, including the zygomatic complex ZMCit is rare to be broken in isolation.
Surgical Management of a Mandible Subcondylar Fracture
While rare, bilateral mandible fractures that are unstable can cause the tongue maneibular fall back and block the airway. Therefore, careful reconsideration between the treatment efficacy and overall patient comfort is subcondykar when we develop a treatment plan for subcondylar fractures. However several radiologic studies demonstrate a better anatomical reduction after the ORIF treatment 1945 — Few studies emphasize on the indications of this treatment procedure 27but as a general rule, the need for anatomic reduction in complex fractures is one reason to employ the open reduction and internal fixation approach.
