Summary
This case study presents a novel orthodontic approach for hemimandibular hyperplasia, avoiding extensive surgery. The treatment successfully rebalanced the bite and improved facial symmetry, offering a viable alternative for patients refusing traditional orthognathic surgery.
Area of Science:
- Dentistry
- Orthodontics
- Oral and Maxillofacial Surgery
Background:
- Hemimandibular hyperplasia is a rare developmental condition causing unilateral mandibular enlargement and facial asymmetry.
- Standard treatment involves complex surgical-orthodontic procedures, which may not be suitable for all patients.
Observation:
- A 32-year-old male presented with a 15-year history of progressive right-sided facial asymmetry due to hemimandibular hyperplasia.
- The patient declined conventional bimaxillary orthognathic surgery.
Findings:
- A modified treatment plan combined pre-surgical orthodontic decompensation, condylectomy, and post-surgical orthodontic refinement.
- The patient achieved bite rebalancing, improved arch intercuspation, and anterior open bite closure within three months.
- Two-year follow-up demonstrated stable mandibular function and aesthetically acceptable results, with persistent minor chin asymmetry.
Implications:
- This minimally invasive approach offers an effective alternative for managing hemimandibular hyperplasia in patients who decline extensive surgery.
- The findings highlight the potential of tailored orthodontic techniques combined with targeted surgical intervention for complex craniofacial asymmetries.
- Further research is warranted to evaluate the long-term stability and broader applicability of this treatment strategy.
