condylar hyperplasia
Excessive growth of the mandibular condyle causing facial asymmetry and malocclusion.
Full Definition
Condylar hyperplasia is a benign condition characterized by excessive, progressive growth of the mandibular condyle, resulting in unilateral mandibular enlargement and facial asymmetry. The condition typically manifests during adolescence and may continue into early adulthood. Patients present with progressive facial asymmetry, midline deviation, and malocclusion. Diagnosis often requires bone scintigraphy to determine growth activity. Treatment depends on whether growth is active or inactive and may include high condylectomy, orthognathic surgery, or a combination approach to restore facial symmetry and proper occlusion.
Usage
Usage note: Always specify whether the condition is active or inactive based on imaging studies.
