INTRODUCTION: Maxillo-mandibular advancement (MMA) is the most successful surgical treatment for OSAS. This study prospectively evaluated soft tissue changes in typical OSAS patient before and after MMA.
MATERIAL AND METHODS: Ten patients with severe OSAS, who underwent MMA, were considered. Age, BMI, polysomnographic recordings and cephalometric data were examined. Facial surface data acquired using a 3D laser scanner before (T0) and 1 year (T1) after surgery were pooled by electronic surface averaging to obtain the mean T0 and T1 facial model. A virtual optimal face (V) was used as control group. Mean T0, T1 and V models were compared.
RESULTS: The mean AHI improved from 69.8 ± 35.2 to 17.3 ± 16.7. The mean maxillary advancement was 9.2 mm ± 1.2 and the mean mandibular advancement was 10.4 mm ± 2.2. The comparison between T0 and T1 showed an overall increase of the sagittal projection of the cheeks, lips and of the chin. The comparison between T1 and V showed a transversal increase of the cheeks at the cross section through ch (cheilon).
CONCLUSION: MMA is a highly effective treatment for OSAS. The evaluations of 3D laser scanning showed that surgery in OSAS patients didn't cause an impairment of the facial appearance.
