Summary
Hemimandibular hyperplasia, a rare mandibular malformation, involves jaw enlargement due to condylar hyperactivity. Surgical treatment, including orthopedic maxillary management, showed satisfying results and stability in most patients.
Area of Science:
- Craniofacial surgery
- Orthodontics
- Pediatric dentistry
Background:
- Hemimandibular hyperplasia is a rare, asymmetrical malformation causing mandibular enlargement.
- It's characterized by condylar, neck, ramus, and body hypertrophy, often affecting maxilla growth post-puberty.
- Pathogenesis is linked to condylar hyperactivity and proliferating cartilage.
Purpose of the Study:
- To present a series of hemimandibular hyperplasia cases treated surgically.
- To evaluate the efficacy of orthopedic maxillary management in growing patients.
Main Methods:
- Retrospective analysis of nine patients with hemimandibular hyperplasia treated between 1992-1994.
- Application of orthopedic maxillary management in two patients to stabilize the maxillary occlusal plane.
Main Results:
- Most surgical treatments yielded satisfying clinical outcomes.
- Good postoperative stability was observed in the majority of cases.
- Orthopedic maxillary management demonstrated effectiveness in maintaining occlusal plane position.
Conclusions:
- Surgical interventions for hemimandibular hyperplasia can achieve favorable results.
- Orthopedic maxillary management is a viable approach for managing this condition in growing individuals.
- Early intervention and tailored treatment are crucial for optimal outcomes.
