Bilateral Condylar Fracture of the Mandible | Procedure: Non-surgical Procedure: Non-surgical / Surgical Procedure: Surgical |
Fractures of the condyles occur in around one third of patients sustaining a mandibular fracture. Bilateral fractures are reported in around one fifth to one third of all fractures of the mandibular condyles and are often combined with other fractures of the mandible or facial skeleton.
The treatment of condylar fractures, and in particular of bilateral condylar fractures (BCFx), is complex due to many different fracture patterns, surgeon's preferences, local constraints of the health care system and patient characteristics. Briefly, BCFx can be treated using either closed treatment (CTx) (e.g. intermaxillary fixation [IMF] and/or functional therapy) or surgical treatment (i.e. open reduction and internal fixation [ORIF]) in both fractures, or a combination of closed treatment and ORIF. The relationship of these treatments with the final outcome remains elusive, since the available literature does not report specific data for patients sustaining BCFx and has ignored or inadequately reported patient-reported outcomes. Consequently there is a lack of clinical evidence to assist the decision-making process.
Therefore, the purpose of this registry is to collect data in a standardized manner regarding the treatment, the clinical and the patient-oriented outcomes, and the complications of BCFx.

Bicondylar Fracture
Patients presenting a bilateral condylar fracture of the mandible with or without additional symphyseal fracture. Bilateral condylar fractures will be treated non-surgical, surgical or combining both.

- Mandibular movements (mobility index) [ Time Frame: 3 months ]
- Interincisal opening/maximal opening is defined as distance in millimeters between the edges of the incisors of the mandibular and the maxillary bone.
- Lateral movements: With the mandible slightly open, it is defined as the distance in millimeters from the labioincisal embrasure between the central incisors to the labioincisal embrasure of the mandibular incisors
- Protrusive movement: With the mandible slightly open, it is defined as the distance in millimeters between the incisal edges of the maxillary central incisor to the mandibular central incisor.
Depending on the score, the mobility index will be calculated as follow:
- 0 points: normal mandibular mobility
- 1 - 4 points: slightly impaired mobility
- 5 - 20 points: severely impaired mobility
- Mandible dysfunction (Helkimo Index) [ Time Frame: 6 weeks / 3 months ]
- Clinical evaluation of the occlusion status [ Time Frame: 6 weeks / 3 months ]
- Normal for the patient
- Abnormal for the patient (anterior open bite / crossbite / lateral open bite in the premolar area / lateral open bite in the mola area)
- Pain (numeric rating scale) [ Time Frame: 6 weeks / 3 months ]
