In skeletal class III malocclusion with mandibular deviation, short-side condyles with continuous cortical architecture and CRSS ≥8 are classified as normally developing, while long-side condyles exhibit hyperplastic growth. The CH/RPH ratio (≈0.59 for normal versus ≥0.69 for hyperplastic condyles) critically distinguishes these developmental patterns. Using the Obwegeser classification, this study demonstrates that skeletal class III malocclusion with mandibular asymmetry exclusively presents as type II (simple condylar hyperplasia) in unilateral mandibles, with significant enrichment of condylar hyperplasia in the long-side group.
