Facial asymmetry in young adults may indicate unilateral condylar hyperplasia or internal derangements. Standard radiographs can help differentiate these conditions, especially when other imaging is unavailable.

Area of Science:

  • Dentistry
  • Orthodontics
  • Radiology

Background:

  • Facial asymmetry is a common concern, often linked to mandibular development.
  • Unilateral mandibular condylar hyperplasia and internal derangements are potential causes.
  • Differentiating these conditions is crucial for appropriate treatment planning.

Purpose of the Study:

  • To investigate the radiographic differences between patients with apparent unilateral mandibular condylar hyperplasia and those with unilateral internal derangements.
  • To determine the utility of standard radiographs in distinguishing these conditions.

Main Methods:

  • Retrospective study of twelve patients (mean age 24) with facial asymmetry.
  • Classification into two groups: apparent condylar hyperplasia and unilateral internal derangements.

  • Comparison of angular and linear measurements using statistical tests (Student's t-test, ANOVA).

    • Main Results:

    • No significant radiographic differences were found between the two groups based on standard measurements.
    • The presence of degenerative joint disease was noted on the affected (short) side in patients with internal derangements.
    • Standard radiographs were deemed potentially helpful in diagnosis when advanced imaging is not utilized.

    Conclusions:

    • Radiographic analysis alone may not reliably differentiate unilateral condylar hyperplasia from internal derangements based on standard measurements.
    • Degenerative joint disease on the affected side is a key indicator in internal derangements.
    • Standard radiography remains a valuable tool, particularly in resource-limited settings or as an initial diagnostic step.
