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.

Endoscopic approach to subcondylar mandible fractures. Duverney fracture Pipkin fracture. A method by questionnaire. Lisfranc Jones March Calcaneal. For other uses, see Broken jaw disambiguation. Privacy Policy Terms of Use. There are some limitations with regard to retromandibular approaches, in that, if the subcondylar fractures are located in the high subcondyle and close to the condylar head, the space that can be exposed with this approach is restricted; therefore, we modify the retromandibular incision.

Even though early clinical fractur 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 — Clinical Challenges in Otolaryngology.

Surgical Management of a Mandible Subcondylar Fracture

Mandibular motion after closed and open treatment of unilateral mandibular condylar process fractures. 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.

A systematic literature review”. 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. InMeyer’s photoelastic analysis [ 14 ] demonstrated the presence of compressive stress patterns along the posterior border of the ramus and tensile stress patterns parallel and inferior to the sigmoid notch.

When we operate on a subcondylar fracture, the treatment plan depends on, 1 whether open or closed reduction must be performed, 2 which approach to the fracture site will be used, and 3 what type of osteosynthesis is required.

This article has been cited by other articles in PMC. The study of conservative treatment of condylar fractures carried out by Zachariades et al. Our website uses cookies to enhance your experience. First and foremost is compromise of the airway. To align the teeth, circumdental wiring is often used where wire fractute typically 24 gauge or 26 gauge are wrapped around each tooth then attached to a stainless steel arch bar.


Wiring of the teeth helps stabilize the fracture either during placement of osteosynthesis or as a treatment by itselfso the lack of teeth will guide treatment. Although surgical management has been attempted in the hope of obtaining better results, some problems have remained, including difficulty in accessing the fracture site and insufficient or failed reduction of the fracture. After the skin incision, the subcutaneous dissection allows for the extension of the surgical wound to the level of the fracture.

Great care must be taken when performing the open reduction and internal fixation of the body fractures to assure the mandible is narrowed to its pre-injury status.

Males in their 30s [1]. Condylar fractures are deep, so it is rare to see significant swelling although, the trauma can cause fracture of the bone on the anterior aspect of the external auditory meatus so bruising or bleeding can sometimes be seen in the ear canal.

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 ]. Ellis E, 3rd, Dean J. In addition to the potential for airway compromise, the force delivered to break the jaw can be great enough to either fracture the cervical spine or cause intra-cranial injury head injury.

Textbook of Oral and Maxillofacial Surgery. A new operation for displaced fractures at the neck of the mandibular condyle. This article was invited as part of a panel presentation, which was one of the most highly rated sessions by participants, at the 69th Congress of the Korean Society of Plastic and Reconstructive Surgeons on November 11, in Seoul, Korea. On the other hand, the simplified version better reflects the clinical treatment implications.

Images can be reconstructed into a 3-dimensional view, to give a better sense of the displacement of various fragments. Tests of two-plate fixation technique 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 ].


Mandibular Subcondylar Fractures: A Review on Treatment Strategies

Open reduction is sometimes combined with use of an endoscope to aid visualization of fracture site. Copyright American Medical Association. The Journal of Craniofacial Surgery.

Since the surgical techniques and technology, as well as the indications, continue to develop, there are few data in the literature regarding the outcomes of endoscopic fracture treatment.

A small drain placed into the subcutaneous space may be necessary to prevent a hematoma. The most common long-term complications are loss of sensation in the mandibular nervemalocclusion and loss of teeth in the line of fracture.

A Systematic Review of the Literature”. Panoramic radiographs are tomograms where the mandible is in the focal trough and show a flat image of the mandible.

Endoscopic treatment of facial fractures. A systematic review was unable to find sufficient evidence of the superiority of one method over another in the management of condylar fracturr.

The results of the analysis performed on our model are shown in Fig. Scaphoid Rolando Bennett’s Boxer’s Busch’s.

Archived PDF from the original on While it is against surgical dicta to consider treatment of traumatic injuries through small incisions and limited access, the application of minimally invasive surgery to facial fracture repair has become widespread. National Center for Biotechnology InformationU. In other projects Wikimedia Commons. 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 ].

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 mouth.

Fractures of the mandibular body are defined as those that involve a region bounded anteriorly by the parasymphysis defined as a vertical line just distal to the canine tooth and posteriorly by the anterior border of the masseter muscle.
