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.

The indirect skeletal fixation is accomplished by placing an arch bar, secured to the teeth on the maxillary and mandibular dentition, then securing the top and bottom arch bars with wire loops.

This approach provides a direct approach to the high subcondylar region and the distance from the skin incision to that region is reduced, compared to that of the routine retromandibular approach. This page was last edited on 3 Octoberat If the bones fracture and overlie each other there may be shortening of the height of the ramus.
Considerations in Subcondylar Fracture Management
Once the posterior border of the mandible is reached, an incision is made through the pterygomasseteric sling. According to the Skbcondylar and Kent criteria [ 3 ], the indications for open reduction were limited, because the techniques and materials available at that time were limited [ subvondylar ]. In the case of a unilateral condylar fracture the back teeth on the side of the fracture will meet and the open bite will get progressively greater towards the other side of the mouth.
Patients undergoing surgery had more complaints in the short run, but they were presented with fewer symptoms in long term follow ups. Today, many surgeons prefer open reduction of displaced fractures, because such reduction and rigid fixation enables good anatomic repositioning and immediate function. One is a displaced right mandibulsr fracture and the other is a left parasymphyseal fracture.
The modified retromandibular approach provides the same exposure as the retromandibular and preauricular accesses combined, and it may be useful for procedures involving the high subcondylar region [ 8 ]. Fractuure of Oral and Maxillofacial Surgery. Received May 6; Accepted Jul Black arrow marks right earlobe, white arrow marks head of the condyle.
Mandibular Subcondylar Fractures: A Review on Treatment Strategies
Treatment of post-traumatic open bite by radiofrequency. In high velocity injuries, the soft tissue can be severely damaged far from amndibular bullet wound itself due to hydrostatic shock. Avulsion fracture Chalkstick fracture Greenstick fracture Open fracture Pathologic fracture Spiral fracture.

The proximal point of the incision is just below the ear lobe, runs parallel down to the posterior border of the mandible, and is limited to 25 mm in length. Management of mandible fractures has been mentioned as early as B. Fracure will result in an ipsilateral premature contact of the teeth. The risk of facial nerve mandivular is the problem that needs to be overcome.
July 12,English editing: Sometimes bruising will develop in the floor of the mouth sublingual eccymosis and the fracture can be moved by moving either side of the fracture segment up and down. When the fracture is intracapsular there is a higher rate of late-term osteoarthritis and the potential for ankylosis although the later is a rare complication as long as mobilization is early.
Patient benefit from endoscopically assisted fixation of condylar neck fractures-a randomized controlled trial.
B It provides good visualization of the high subcondyle and allows straightforward fracture management. Head, face and neck trauma comprehensive management.
British Journal mandibklar Oral and Maxillofacial Surgery. The aim of this study was to review the different treatment strategies of these fractures in adults: With a condylar fracture, there is very fractuee shortening of the ramus on the affected side. Abstract Open reduction and fractuee reduction can create better function for the temporomandibular joint, compared with closed treatment in mandible fracture surgery.
The magnitudes and directions of the principal components of strain on the four faces of the condylar process were first determined by Throckmorton and Dechow [ 13 ] who fractur an in vitro study of human mandibles in The most common complaint of patients after six months was chronic pain after the closed reduction and a noticeable scar after the surgical treatment 2244 Perhaps no area of facial trauma has inspired more controversy than the management of mandibular subcondylar fractures.
Open reduction can restore the anatomic position of the subcondyle, thus yielding better function of the TMJ compared to closed reduction. Open reduction was described as early as According to literature, it is said that by using the endoscope, a variety of methods are possible. The condylar fragment may be displaced most often laterally based on the angulation of the fracture and predominant muscle pull. First and foremost is compromise of facture airway.
Overall it is safe to declare that endoscopic surgery is certainly a good replacement for approaches through the skin, for subcondylar fractures.
