PurposeOur aim was to explore how the remodeling capacity of children's mandibular condyles affected the morphological changes of fractured condyles after conservative treatment.MethodsA retrospective study was designed and performed on children and some adult patients with mandibular condylar fractures. Computed tomographic (CT) imaging was reviewed for all patients to analyze the morphological changes and risk factors of traumatic temporomandibular joint ankylosis.ResultsFrom 2012 to 2017, there were 81 patients younger than 18 and 10 adult patients who accepted treatment in our department. There were 23 young patients (aged < 18 years) with 41 fractured condyles and 10 adults with 14 fractured condyles who were managed with conservative treatment, and the morphological changes were analyzed with the aid of Mimics 19.0 software. The fractured condyles with intracapsular fractures completed the remodeling progress within 3-4 months and condyles with neck or base fractures took more than 6 months. Differentely, we found no remodeling in adults. Three of the 81 young patients suffered temporomandibular joint ankylosis. Each case was analyzed regarding the risk factors, morphological changes, and remodeling features. Finally, the common points of these cases were summarized.ConclusionsThe shape of fractured condyles can remold after conservative treatment in young patients, instead of bony fusion between the fractured fragments compared with the adult patients.
