Long-term results after childhood condylar fractures. A computer-tomographic study

Area of Science:

• Orthodontics
• Oral and Maxillofacial Surgery
• Radiology

Background:

• Condylar fractures in the temporomandibular joint (TMJ) during growth can impact development.
• Understanding the long-term effects of these fractures is crucial for treatment planning.

Observation:

• A computer-tomographic study examined 12 patients with prior condylar fractures during their growth period.
• Specific attention was given to low condyle fractures with medial luxation of the smaller fragment.

Findings:

• Remodelled condyles often presented as two distinct parts: a medial segment (likely residual fragment) and a lateral segment (likely callus formation).
• Flattening of the glenoid fossa, characterized by roof thickening, was observed in some patients.
• Additional cases included post-traumatic ankylosis and a bifid condyle.

Implications:

• This study provides insights into the complex remodelling processes of the TMJ following pediatric condylar fractures.
• Findings may inform clinical management and predict long-term outcomes for patients with similar injuries.
• Further research can explore the functional consequences of these remodelling patterns.
