Abstract
Background: The causes of mandibular condylar hypoplasia can be congenital or acquired in nature. Cited local causes of acquired hypoplasia include trauma, infection and irradiation. We report a case of hypoplastic condyle that was attributed to temporomandibular joint (TMJ) disc displacement without reduction (DDwoR).
Clinical Presentation: A 16-year-old male presented with restricted mouth opening and right TMJ pain for 6 months. He was subsequently diagnosed with DDwoR. Conservative treatment comprising self-care and moist-heat therapy was administered and he was followed for 27 months without any further interventions. During this period, transitions from “normal” morphology to condylar flattening / erosion, and eventually a re-modeled smaller “normal” right TMJ were observed.
Conclusion: The present case provided initial support that DDwoR could be a plausible cause of condylar hypoplasia in adolescents / young adults.
Keywords: Temporomandibular disorders, condylar hypoplasia, disc displacement without reduction, osteoarthritis, degenerative joint diseases, condylar remodeling.
