Summary
Active unilateral condylar hyperplasia predominantly affects females and the right side, with hemimandibular elongation being most common. Combined surgical approaches yield stable outcomes and improve patient quality of life.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Plastic Surgery
Background:
- Unilateral condylar hyperplasia (UCH) is a complex condition affecting facial growth.
- Accurate diagnosis and tailored surgical planning are crucial for optimal outcomes.
Purpose of the Study:
- To review demographic and diagnostic data of patients with active UCH.
- To report on surgical interventions, sequencing, and treatment outcomes, including quality of life.
Main Methods:
- Retrospective analysis of 80 patients diagnosed with active UCH.
- Assessment of demographic, treatment, and outcome data.
- Quality of life evaluated using a 21-question questionnaire.
Main Results:
- Hemimandibular elongation (61%) was more frequent than hemimandibular hyperplasia (30%).
- The condition predominantly affected females (65%) and the right side (61%).
- High success rates (88%) in achieving Class I occlusion and patient satisfaction (96%) were reported.
Conclusions:
- UCH and hemimandibular elongation are more prevalent in females, often presenting in adolescence.
- Simultaneous condylectomy and orthognathic surgery offer predictable and stable results for UCH.
- Treatment significantly improves the quality of life for patients with UCH and dentofacial deformities.
