Mandibular fractures with temporomandibular joint dislocation and masticator space blow-out fracture
Presentation
Road traffic accident.
Patient Data
A displaced bony fragment of the left posterolateral maxillary sinus with herniated soft tissue component into the sinus cavity feature consistent with a masticator space blow-out fracture.
Fracture dislocation involving the right mandibular condyle that became horizontally located in the coronal plane.
A fracture involving the bony component of the right external auditory canal with an inferolateral displacement of the bony fragment.
A left-sided linear fracture involving the anterior portion mandibular body.
Soft tissue edema or sinus fluid are not obvious in this case indicating these are non-recent injuries.
Case Discussion
In the setting of jaw fractures or the presence of masticator space soft-tissue edema, carefully search this type of blow-out fracture.
