Treatment of Intra-articular Fractures of the Mandibular Condyle (FIAC)
Open Versus Closed Treatment of Intra-articular Fractures of the Mandibular Condyle: a Multicentre Randomized Controlled Trial
Intra-articular fractures of the mandibular condyle ((IAFC) are usually treated by means of physical therapy with or without transient maxillo-mandibular fixation (conservative or closed treatment). However, this can lead to incomplete manducatory function recovery due to limited mandibular mobility. During the last 15 years, a growing interest has emerged for open (surgical) treatment of these fractures. Although there is more and more evidence suggesting that the open treatment may be the treatment of choice for selected cases of subcondylar fractures, the best option remains controversial for high condylar fractures.
The primary objective of the trial is to compare mandibular mobility at 3 months post-treatment between open (surgical) and closed (conservative) treatment of intra-articular fracture (high fracture) of the mandibular condyle.
This study is an open multicenter randomized controlled trial with 2 parallel arms. Eligible patients will be randomized 1 :1 between open and closed-treatment group.

Detailed Description
The mandibular condyle is one of the most frequent locations of facial fractures. It can lead to severe functional impairment if the occlusion is not properly restored and the mandibular mobility not recovered totally or within an acceptable range. Most frequent sequels of these fractures include limitation of mandibular movements resulting in limited mouth opening, occlusal disturbance causing chewing malfunction, chronic pain, chronic temporo-mandibular joint (TMJ) disorder and facial asymmetry. The risk of permanent limited mouth opening is even higher when the fracture is located inside the TMJ. Although the superiority of surgical treatment is now widely accepted for low-level fractures of the condylar unit (i.e., extra-articular fractures) the treatment of fractures involving the TMJ in adult patients is still controversial.
Treatment principles in these fractures can be ranked in two groups: closed and open treatments. Closed treatment - also called closed reduction or conservative treatment - consists in prolonged physical therapy frequently associated with transient maxillo-mandibular fixation (MMF). Open treatment consists in open reduction and internal fixation of the fracture (ORIF).
No randomized controlled trial has ever evaluated the superiority of open versus closed treatment, and treatment strategy for IAFC remains a matter of ongoing debate.
The primary objective of this trial is to compare mandibular mobility at 3 months post-treatment between open (surgical) and closed (conservative) treatment of intra-articular fracture (high fracture) of the mandibular condyle.
The secondary objectives are to compare between open (surgical) and closed (conservative) treatments:
At 3 weeks, 6 weeks, 3 months, 6 months, and 12 months post-treatment:
- maximal mouth opening (in mm)
- maximal mandibular protrusion (in mm),
- maximal lateral excursion (in mm),
- lateral deviation of the mandible during mouth opening
- occlusal disturbance evaluated by both the patient and the surgeon
- pain using a visual analog scale
- subjective functional impairment as assessed by the Mandibular Function Impairment Questionnaire
Overall:
- duration of sick leave
- time to normal activity recovery (social activities, eating, sports) We will also evaluate compliance with the intervention. This trial is an open multicenter randomized controlled trial with 2 parallel arms. Eligible patients will be randomized 1 :1 between open and closed-treatment group.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maximal mouth opening (in mm) at 3 months
Time Frame: 3 months (+/-10 days)
|
It will be obtained by measuring the interincisal distance at maximum mouth opening with a caliper or a ruler.
The patient will be first asked to open the mouth as widely as possible for 3 seconds and to rest for 5 seconds.
This sequence will be repeated 2 times and at the third repetition the patient will keep his/her mouth opened while the physician will measure inter-incisal distance
