Abstract

Introduction: High attention of modern society to beauty and beauty surgery specially ORTHOGNATHIC SURGERY shows the importance of assessment of the ability of this surgery in changing parameters and soft tissue proportion and finally changing in attraction and beauty. Because of the ability of soft tissue in beauty and masking the defects of hard tissue, assessment of the changes during the ORTHOGNATHIC SURGERY seems important.Materials and Methods: In Ghaedi clinic (that is for Isfahan university) the patients are among the candidates of maxillary osteotomy (only LEFORT I OSTEOTOMY or Bimax surgery). With coordination of surgeon, the standard cephalometrices are prepared before and six months after the surgery and then soft tissue selected analysis are done. The cephalometrices, that are prepared before and after the surgery, are compared and according to paired T-test are analysed. The changes in parameters between two groups of surgery (one group with ANS-cut and another without ANS-cut) are compared, too. The data of two groups according to independent T-test are analysed. The total samples were sixteen (eight samples in each group). A sincere statistics adviser helped me in this way.Results: According to the results, after the surgery, we see some changes in all of the parameters and proportions. We have statistical significant difference between the means of UPPER LIP LENGTH before and after the surgery in uncut group (p value <0.05). We didn't have statistical significant differences in other parameters in different situations (before and after the surgery or the difference between two groups). The differences might be so little that these are not significant with the samples. Also the nasolabial angle with the most differences, isn't significant. It's because of the high standard deviation.Conclusion: As a result, we can assert that the maxillary osteotomy has the most changes on nasolabial angle. During of the follow (6 months), we observed a decrease in upper lip vermilion and increase of UPPER LIP LENGTH & also nasolabial angle. Despite of the numerical differences that almost were not statistically significant, clinical changes of soft tissue following the maxillary LEFORT I OSTEOTOMY are noticable. Also we can nearly predict the changes.
