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. Background and objective: Mandibular fractures are the most frequent and sub condylar region is a common site of fracture. Proper.

Unilateral condylar fracture may cause restricted and painful jaw movement. In conclusion, we declare that the endoscopic surgery is certainly a good replacement for approaches through the skin, for subcondylar fractures, but still more randomized clinical trials are needed to be carried out on this issue.
This technique may be considered a useful means for fixation in order to reduce the postoperative internal maxillary fixation period and achieve early mobility of the jaw. Today, for dislocated subcondylar fractures, open approaches are considered the treatment of choice in many surgical units. The wound is also reapproximated in layers, and the SMAS is resuspended.

Closed reduction with maxillomandibular fixation Closed reduction was historically considered the standard treatment for subcondylar fractures CT or digital volume tomography DVT imaging may be used as an alternative.
Loss of consciousness combined with aspiration of tooth fragments, blood and possibly dentures mean that the airway may be threatened. There is no subcondylae of interest to be declared. Lo J, Cheung LK.
This is done with either an open technique, where an incision is made, the fracture is found and is physically manipulated into place, or closed technique where no incision is made.

However, all of those plates made by Medartis are mandibulad yet available in the Republic of Korea. The facial bones can be visualized as slices through the skeletal in either the mandigularcoronal or sagittal planes. However in bilateral fractures, segments are more prevalently prone to displacement, subcondylat an ORIF approach is recommended.
Since mandible fractures are usually the result of blunt force trauma to the head and face, other injuries need to be considered before the mandible fracture. Other fractures of the body, are classified as open or closed.
Considerations in Subcondylar Fracture Management
While mandible fractures have similar complication rates whether treated immediately or days later, older fractures are believed to have higher non-union and infection rates although the data on this makes it difficult to draw firm conclusions. Open versus closed treatment of fractures of the mandibular condylar process-a prospective randomized multi-centre study.
One is a displaced right angle fracture and the other is a left parasymphyseal fracture. The condylar fragment may be displaced most often laterally based on the angulation of the fracture and predominant muscle pull.
This results in gagging of the teeth on the fractured side the teeth meet too soon on the fractured side, and not on the non fractured side, i. By far, the two most common symptoms described are pain and the feeling that teeth no longer correctly meet traumatic malocclusion, or disocclusion.
On the right side, the height of the mandible is not reduced. This 3-D reconstruction illustrates a high neck fracture with displacement. A blow to the anterior mandibular body is the most common reason for condylar fracture. Acknowledgments This research received no specific grant from the government or any other funding agency in the public, commercial, or not-for-profit sectors.
Mandibular fracture – Wikipedia
Arch Otolaryngol Head Neck Surg. Contemporary oral and maxillofacial surgery 5th ed. With enhanced experience mandibulqr the surgeons toward the endoscopic technique the controversies over the right treatment choice would slowly subside. Reappraisal of the surgical strategy in treatment of mandibular condylar fractures.
Mini-retromandibular approach to low subcondylar fractures A Preoperative design of a mini-retromandibular incision. With a condylar fracture, there is very often shortening of the ramus on the affected side.
Fractures where large cysts or tumours are in the area and weaken the jawwhere there is an area of osteomyelitis or where osteonecrosis exist cause special challenges to fixation and healing.
The opposite of a simple fracture msndibular a comminuted fracture, where the bone has been shattered into fragments, or there are secondary fractures along the main fracture lines. There may be swelling over the temporomandibular joint region and bleeding from the ear because of lacerations to the external auditory meatus.
Ideally, two miniplates should be applied at the posterior and anterior border of the condylar neck in a triangular fashion with one plate below the sigmoid notch and another plate along the posterior border of the ramus [ 10 ]. External fixation, which can be used with either open or closed reduction uses a fractuure system, where long screws are passed through the skin and into either side of a fracture segment typically 2 pins per side then secured in place using an external fixator.
It is wise to emphasize on the short duration of this procedure also 41butfor the surgeons who are newly utilizing this method, there is probably much more time to perform the anatomic reduction and do the surgery than the conventional extraoral methods.
Instead, the blood supply comes largely from the periosteum.
