Team management and treatment outcomes for patients with hemifacial microsomia.

Abstract

INTRODUCTION:

Hemifacial microsomia is the most common congenital craniofacial anomaly after cleft lip and palate. The purpose of this study was to evaluate the final outcome of team care for patients with hemifacial microsomia after a protocol of growth management, orthodontic treatment, orthognathic surgery, and soft-tissue augmentation.

METHODS:

This was a retrospective study with chart reviews, radiographs, and photographs to document the treatment interventions and outcomes. Six patients, 2 in each of 3 mandibular types, who had recently completed treatment and had complete records available and were not previously reported, were included. Facial midlines and maxillary and mandibular deviations from the midline were measured.

RESULTS:

The maxillary deviation changed by 10.0 ± 4.6 mm to a deviation from the midline of 1.1 ± 0.6 mm. The chin deviation improved by 8.1 ± 2.7 mm to a mean distance of 0.6 ± 0.5 mm from the midline. The occlusal plane can't changed from 7.0° ± 4.2° to 2.3° ± 1.4°. All changes were significant.

CONCLUSIONS:

Facial asymmetry in patients with hemifacial microsomia can be significantly improved by stepwise orthodontic treatment, orthognathic and facial surgery, and soft-tissue augmentation. As for most craniofacial conditions, team care is essential.
