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.

Biglioli F, Colletti G. Computed tomography is the most sensitive and specific of the imaging techniques. Cervical fracture Jefferson fracture Hangman’s fracture Flexion teardrop fracture Clay-shoveler fracture Burst fracture Compression fracture Chance fracture Holdsworth fracture.
The best treatment for condylar fractures is controversial. Purchase access Subscribe to JN Learning for one year. In these cases, oral surgeons sometimes opt for external fixation, closed reduction, supraperiosteal dissection or other techniques to maintain the periosteal blood flow. Rigid fixation of mandibular condyle fractures.
Surgical Management of a Mandible Subcondylar Fracture
Others however argue that a surgical access to the mandibular condyle, would increase the risk of trauma to the facial nerve and leave unpleasant scaring 2732 — Therefore, careful reconsideration between the treatment efficacy and overall patient comfort is needed when we develop a treatment plan for subcondylar fractures. Masticatory motion after surgical or nonsurgical treatment for unilateral ffacture of the mandibular condylar process.
In addition, broken, missing or malaligned teeth can often be appreciated on a panoramic image which is frequently lost in plain films. Other fractures of the body, are classified as open or closed.
Fractures of the condylar process unilateral or bilateral can occur in isolation. Patients undergoing surgery had more complaints in the short run, but they were presented with fewer symptoms in long term follow ups.
Mandibular Subcondylar Fractures: A Review on Treatment Strategies
These fractures are very difficult to treat. For angle and posterior body fractures, when the angle of the fracture line is angled back more posterior subconcylar the top of the jaw and more anterior at the bottom of the jaw the muscles tend to bring the fracture segments together.
Once the decision has been made that the fracture rfacture the criteria for an open approach, the decision tree branches once again to include the recent addition of endoscopic guidance during fracture reduction and stabilization. A Cochrane review assessed clinical studies on surgical open reduction and non-surgical closed reduction management of mandible fractures that do not involve the condyle. Support Center Support Center.
It can also avoid direct contact with the facial nerve and preserves the integrity of the parotid gland as well as its capsule and leaves a barely noticeable scar in a relatively hidden region [ 1 ]. CT or digital volume tomography DVT imaging may be used as an alternative. Clinical findings Direct trauma to the TMJ area is unusual but may be associated with maneibular of the zygomatic complex.
Ramus fractures are said to involve a region inferiorly bounded by an oblique line extending from the lower third molar wisdom tooth region to the posteroinferior attachment of the masseter muscle, and which could not be better classified as either condylar or coronoid fractures.
Example of a high neck fracture 3-D mandibulad are useful in identifying fracture height, direction and severity of displacement. Open reduction involves surgical exposure of the fracture site, which can be carried out via incisions within the mouth or incisions subcondylra the mouth over the area of the condyle.
Br J Oral Maxillofac Surg. MMF was not generally needed but restricted jaw movement with bandaging and a soft diet were used for 1 week. The skin incision runs from subocndylar intertragal notch through the use of a gently curved incision around the ear lobule and uses the upper part of the retromandibular incision Fig.
Mandibular fracture – Wikipedia
C Postoperative X-ray, the two 2. Copyright Subcpndylar Medical Association. Condylar, ramus, and coronoid process fractures are subcondylad closed whereas angle, body and parasymphsis fractures are generally open. The condylar process and head is a subunit of the mandible and is defined by an oblique line running backward from the sigmoid notch to the upper masseteric tuberosity.
It is common for both to be assessed with facial fractures. The Cochrane Farcture 1: Following, the Subcondyla classification is presented along with a simplified version. 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.
The trapezoid shape of the TCP plate Medartis, Basel, Switzerland ensures the best possible stability of the fracture site and an optimal resistance of the plates to local mechanical strains Fig. During the past decade, surgeons became intrigued with the concept of minimally invasive surgery to avoid the patient morbidity that could arise from more traditional open surgical techniques eg, laparoscopic techniques. Mandibular fractures that involve the tooth-bearing portion of the jaw are by definition compound fractures,  because there is at least a communication via the periodontal ligament with the oral cavity and with more displaced fractures there may be frank tearing of the gingival and alveolar mucosa.
Long-term outcomes of endoscopic-assisted repair of subcondylar fractures are similar to those obtained with open and closed approaches, but the intraoperative benefits of improved visibility in an illuminated and magnified field of view, decreased bleeding, and better anatomic reduction, as well as expected decreased postoperative patient morbidity eg, pain, edema, and limitation of openingmake endoscopy an attractive surgical adjunct.
Outside the mouth, signs of swelling, bruising and deformity can all be seen. Condylar fractures are classified by location compared to the capsule of ligaments that hold the temporomandibular joint intracapsular or extracapsulardislocation whether or not the condylar head has come out of the socket glenoid fossa as the muscles lateral pterygoid tend to pull the condyle anterior and medial and neck of the condyle fractures.
Note that the teeth to the left of the fracture do not touch. Perhaps no area of facial trauma has inspired more controversy than the management of mandibular subcondylar fractures.
