How is a Subcondylar fracture treated?
The treatment of subcondylar fractures can be divided into two major treatment methods: closed treatment or closed reduction (CR) and open reduction and internal fixation (ORIF). CR requires a period of maxillomandibular fixation (MMF), followed by active physiotherapy.
What is a Subcondylar fracture?
Subcondylar fractures are, by definition, below the attachment of the joint capsule and in general are devoid of ankylosis. Therefore, maxillomandibular fixation is recommended to be applied for a period of 4 to 6 weeks in most cases.
What is an open mandible fracture?
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. It may result in a decreased ability to fully open the mouth. Often the teeth will not feel properly aligned or there may be bleeding of the gums.
Which fracture causes anterior open bite?
We believe that this movement was caused by the patient’s condylar fractures and the subsequent remodeling. Although there was some relapse, our results suggest that implant anchorage is useful for correcting anterior open bites originating from condylar fractures.
How do you fix an anterior open bite?
Methods: The gold standard treatment of skeletal anterior open bite cases is the combined approach of orthodontic treatment with fixed appliances and orthognathic surgery. In recent years, temporary anchorage devices (TAD) have been developed to correct anterior open bites orthodontically.
What is the difference between subcondylar fractures and mandibular fractures?
Subcondylar mandibular fractures differ from the fractures located more distally in the mandible for 2 main reasons. First, these fractures are in close proximity to the temporomandibular joint, which is probably the most important structure for maintaining a normal chewing function.
When is open reduction indicated for a subcondylar fracture of the mandible?
As noted earlier, the foremost reason to perform open reduction of a subcondylar fracture of the mandible is the inability to reduce the occlusion, particularly if this inability persists under general anesthesia with muscle relaxation.
What is the best treatment for subcondylar mandibular fractures?
C losed reduction with rigid and/or elastic maxillomandibular fixation provides results as good as open techniques in the management of subcondylar mandibular fractures. Subcondylar mandibular fractures differ from the fractures located more distally in the mandible for 2 main reasons.
What is the duration of maxillomandibular fixation for subcondylar fractures?
Subcondylar fractures are, by definition, below the attachment of the joint capsule and in general are devoid of ankylosis. Therefore, maxillomandibular fixation is recommended to be applied for a period of 4 to 6 weeks in most cases. Open reduction with internal fixation can increase the risk for facial nerve damage during the operative approach.
