MANDIBULAR SUBCONDYLAR FRACTURE PDF
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.

Mandibular Subcondylar Fractures: A Review on Treatment Strategies
For comparable fractures, patients who received MMF will lose more weight and take longer to regain mouth opening, whereas, those who receive Mzndibular have higher infection rates. A sharp cut is made through the periosteum at the posterior border of the ascending ramus, opening access to the whole ramus, which is dissected subperiosteally.
According to the Zide and Kent criteria [ 3 ], the indications for open reduction were limited, because the techniques and materials available at that time were limited [ 4 ]. This technique may be considered a useful means for fixation in order to reduce the postoperative internal maxillary fixation fracutre and achieve early mobility of the jaw.
Mandible – Diagnosis – Condylar process and head, simple and complex – AO Surgery Reference
Frscture studies imply a need for new concepts for the application of osteosynthesis plates at the posterior and anterior border of the condylar neck in order to restore tension and compression trajectories [ 8 ]. Report of a case”.
Comparison of functional recovery after nonsurgical and surgical treatment of condylar fractures. For more complicated malocclusions and bigger dislocations however, the open technique is preferable.
Two-plate fixation technique The single-plate fixation technique does not provide sufficient strength to withstand the strains occurring in subcondylar fractures.
Copyright American Medical Association. Biomechanics Hunting bow concept The mandible is similar to a hunting bow in shape, strongest in the midline symphysis and weakest at both ends condyles. Subcodylar example, the “open” surgeons claim better anatomic reduction and postoperative radiographic appearance, while the “closed” surgeons favor a conservative approach with potentially fewer surgical complications and acceptable long-term functional results.

The AO classification allows for better communication between radiologists and surgeons. After transection of the skin, the skin flap is elevated, taking care not to injure the great auricular nerve, which lies over the sternocleidomastoid muscle, and the subcutaneous dissection is extended to the level of the fracture. A Repeated tensile and compression forces are exerted on the subcondyle during mouth opening exercises.

These studies also concluded fractude despite the surgical technique, anatomic reduction, mouth opening, lateral and forward movements of the mandible and the lower rate of pain and discomfort of the patients were considered beneficial in the ORIF group.
In high velocity injuries, the soft tissue can be severely damaged far from the bullet wound itself due to hydrostatic shock.
The resulting scar is very minor, no facial nerve damage is expected and a functional occlusion is ensured with anatomic reduction. Because the jaw can be highly comminuted, MMF and rigid internal fixation can be difficult. The name comes from this injury occurring in soldiers who faint on parade grounds and strike the floor with their chin.
Surgical Management of a Mandible Subcondylar Fracture
The condylar area has a great clinical value due to its important components. Both closed reduction and the endoscopic surgery had acceptable results. Condylar injuries are often a matter of discussion and controversy among maxillofacial topics 1.
This type of fracture involves the alveolusalso termed the alveolar process of the mandible. Archived PDF from the original on Mandibhlar soon as the mandjbular parotid tissue appears from the fascial incision, blunt dissection with a mosquito is used.
CT or digital volume tomography DVT imaging may be used as an alternative.
In treating subcondylar fractures, osteosynthesis is still a functionally challenging problem. Fractures of the mandibular condyle.
Abstract Open reduction and anatomic reduction can create better function for the temporomandibular joint, compared with closed treatment in mandible fracture surgery. Br J Oral Maxillofac Surg.
