Aim of the study: Is to show the possibilities of correction deformities with surgical treatment, without pre-orthodontic treatment.

Materials and methods: We have analyzed 103 patients operated in the Clinic of Maxillofacial Surgery.

Results: The interventions most often have been made in mandible in 43% of cases, in the maxilla 22.% and bimaxillary intervention was 35%. The most common anomaly was progenia, aperthognathia, retrognathia, laterogenia, retrogenia, protrusion of maxilla and different bimaxillary anomalies. Overall number of patients 73.7% of them have declared that they have functional problems and 26.2% have said just aesthetic concerns, but the most cases the patients have done the intervention for the aesthetic reason with surgical interventions have been very satisfied 85.4% of patients, Postop. complications were: relapse in 6.7% of cases, sensibility disturbance 73.7% who persisted from 7 to 90 days after intervention. 11.6% pain on TMJ that had persisted 3–36 weeks. We had one accidental rupture of the N. alveolaris inf. and one case the rupture of N. mantalis.

Conclusion: Orthognatic surgery offers good opportunities for improvement of the functional and aesthetic problems for the patients, but the lack of the pre operative orthodontic treatment may not be compensated always only with surgery.
