Treatment of hemifacial microsomia using conventional orthodontic techniques Report of a case with long-term follow-up

Background and Overview. The authors successfully treat a case of hemifacial microsomia involving unilateral condylar hypoplasia using conventional orthodontic techniques followed by long-term retention. Case Description. 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.
