Condylar hyperplasia (CH) causes unilateral mandibular overdevelopment, leading to facial asymmetry and malocclusion. Surgical removal of the growth center via condylectomy is the standard treatment for active cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Radiology
Background:
- Condylar hyperplasia (CH) is characterized by excessive growth of the mandibular condyle and ramus.
- It leads to facial asymmetry, malocclusion (e.g., crossbite), and chin deviation.
- The exact etiology and pathogenesis of CH are not fully understood.
Observation:
- Diagnosis relies on clinical, radiological, and bone scintigraphy findings.
- A significant uptake difference (>10%) between condyles on scintigraphy indicates active CH.
Findings:
- The study presents a case of a 46-year-old male with active type II CH (hemimandibular hyperplasia).
- The patient underwent a high condylectomy to address the overgrowth.
Implications:
- Surgical intervention, such as condylectomy, is crucial for managing active condylar hyperplasia.
- Understanding CH pathogenesis is vital for improved diagnostic and therapeutic strategies.
