Fracture of Condylar Process Clinical Trial
Official title:
Trapezoidal Condylar Plate (TCP) Versus Two Miniplates in Treatment of Subcondylar Fracture
Background: Condylar fracture is a common mandibular fracture which accounts for 25-40%. Nowadays the preference started to change towards open reduction because of the late complications that might happen in case of closed treatment. A Transmasseteric Anteroparotid (TMAP) approach for open reduction and internal fixation of condylar fractures overcomes the problems of difficult access and facial nerve injury risk of other conventional approaches. Different plating options are available for internal fixation of the condyle and subcondylar region. Trapezoidal Condylar Plates (TCP) specifically developed for the osteosynthesis of low and high subcondylar fracture. These plates were designed to closely follow the tensile strain lines along the rim of the sigmoid notch anteriorly combined with a posterior arm to parallel the condylar axis free of harmful bending strains.

Eligibility | Inclusion Criteria: - 1- Medically fit patients free from relevant conditions that contraindicate surgery. 2- Patients with age ranged from 20-40 years old. 3- Patients suffering from displaced extracapsular mandibular subcondylar fracture indicated for open reduction including Difficulty of obtaining adequate occlusion by closed method, Radiological signs of the following 1. Deviation of the fragment from the axis of the ascending ramus in medial or lateral direction more than 10°.(22) 2. Shortening of the ascending ramus = 2 mm measured from the roof of glenoid fossa to the inferior border of the ascending ramus of the mandible.(22) 3. Dislocation of the condyle from the glenoid fossa.(48) Exclusion Criteria: - 1. Patients who were not able to follow the information given or to make a decision themselves due to mental or other problems. 2. Any absolute contraindication for surgery. 3. Patient with undisplaced condylar fractures that doesn't cause malocclusion or loss of facial heightening and can be treated conservatively. |
