Case ReportsStaged treatment of temporomandibular joint ankylosis with micrognathia using mandibular osteodistraction and advancement genioplasty.
Distraction osteogenesis can be used to correct micrognathia after temporomandibular joint (TMJ) ankylosis. However, there is still some controversy over the proper sequencing of management for the ankylosed patients. The objective of the present study was to evaluate a staged treatment of TMJ ankylosis accompanied by micrognathia using arthroplasty, mandibular distraction osteogenesis, and advancement genioplasty. ⋯ Our data suggest that a staged and surgical orthodontic treatment might be a better approach to manage TMJ ankylosis accompanied by mandibular hypoplasia. In addition to mandibular osteodistraction, advancement genioplasty should be considered for better improvement in facial esthetics and respiratory function.
