Summary
This study presents a long-term case of a patient with facial asymmetry due to mandibular hyperplasia. Combined orthodontic and orthognathic surgery treatment provided stable results for over 30 years.
Area of Science:
- Orthodontics and Oral and Maxillofacial Surgery
Background:
- Unilateral mandibular condylar hyperplasia can cause significant facial and dental asymmetry.
- Conventional fixed edgewise appliance therapy and orthognathic surgery are treatment options.
Observation:
- A case study of a healthy adult male with marked facial and dental asymmetry.
- Treatment involved fixed edgewise appliance therapy and bilateral sagittal split osteotomy.
- Records were collected pre-treatment, post-treatment, and during long-term follow-up (over 30 years).
Findings:
- The combined orthodontic and surgical approach resulted in stable outcomes.
- Long-term stability was maintained for over three decades post-treatment.
Implications:
- This case demonstrates the long-term efficacy of combined orthodontic and orthognathic surgery for treating mandibular hyperplasia.
- The findings support the use of these treatment modalities for achieving lasting functional and aesthetic results.
