Background and Overview
The authors successfully treat a case of hemifacial microsomia involving unilateral
condylar hypoplasia using conventional orthodontic techniques followed by long-term
A girl aged 10 years and 2 months received a diagnosis of hemifacial microsomia resulting
from unilateral condylar hypoplasia. During a growth period, premature incisal contact
was abolished. After her growth was complete, she received conventional orthodontic
treatment with preadjusted edgewise appliances. After 27 months of multibracket treatment,
acceptable occlusion with a class I canine and molar relationship was achieved. The
occlusion remained stable throughout the 15-year retention period, although there
was a slight facial change.
Conclusions and Practical Implications
Early orthodontic management only can have some limitations but could be one of the
treatment options for hemifacial microsomia.
