Abstract
Correction of facial imbalance and malocclusion associated with maxillary deformities can be achieved by Le Fort 1 osteotomy. This report of two cases is concerned with surgical correction and soft tissue charges of maxillary protrusion & pseudomandibalar prognathism. The Results are as follows.; 1. Cephalometric analysis, clinical evaluation and model analysis led to a diagnosis of maxillary protrusion in one case & Pseudomandibular prognathism in the other. 2. In the first case, Le Fort 1 osteotomy with aet4ack technique and mid-sagittal sectioning were performed to correct the malocclusion & the severe over-jet. 3. Soft tissue changes of the first case are rolling-in of the vermilion border of the upper lip, reducing upper lip prominence, and increasing the antero-posterior dimension of the nose, 4. In the second case, Le Fort 1 ostertomy with augmentation of paranasal area using proplast were performed to advance the retruded and hypotrophic maxilla. 5. Soft tissue changes of the second case improve upper lip-nose balance by rolling-out of the vermilion border of the upper lip, increasing upper lip prominence, decreasing the antero- posterior dimension of the no and augmentation of paranasal area.
