In the le fort I osteotomy performed patients effect of cinch and V_Y sutur on the lip and nose soft tissue

The purpose of this study was to evaluate the effect of cinch suture and VY suture on nose and upper lip appearance for prevention of unexpected changes following maxillary advancement and impaction surgery and to compare the measurements obtained from marked reference points on the nose and lips in 15 concecutive patients.15 orthognatic surgery patient underwent maxillary advancement and impaction surgery because of treatment of malocclusion releted with growth anomally, were included this study. The age of the patients are between 18 and 29 ( mean age 24). 14 class III patients and class I patient were treated by ortognatic surgery. Bimaxillary surgery were applied to all patients. The measurements between the marked references points were recorded to detect the changes on the nose. Lateral cephalometric graphies were obtained preoperatively. As soft tissue edema due to surgey relieses 6 months after the surgery, 6.months after the surgery clinical and radiographic measurements were obtained to compare with the preop data.After ortognatic surgery, in the V-Y suture performed group mean 1,28 mm not significant increased, in the V-Y sutur not performed group mean 0,3 mm not significantly decreased observed. Alar width; in the cinch performed (p=0,010) and not performed group (p=0,016) statistically significant increased observed. The differences between the groups were not statisticially significantly (p=0,463). Subalar widht; in the cinch sutur performed group mean 1,88±0,64 mm significant (p=0,010), in the cinch suture not performed group 2,57±0,53 mm significant increased observed (p=0,015). In this measurement differences between groups were statistically significant (p=0,047). Nasolabial angle; in the cinch suture performed group 4,63º±9,68º decreased, in the cinch suture not performed group 2,29º±8,42º increased observed (p=0,865). Nose nostril height not important changes, in the widht statisticially not significant changes done. When İn the cinch suture performed gruop right nostril widht increased, left nostril widht decreased. İn the cinch suture not performed group right and left nostril width increased observed.
