Aims:The aim of this study was to evaluate hard and soft tissue change after bimaxillary surgery in class III patients by focusing on sella, nasion, A point (SNA) and sella, nasion, B point (SNB) angle and aesthetic outcome.Materials and Methods:The sample consisted of 96 skeletal Class III patients (42 women, 54 men) with a mean age of 25 years with standard deviation (SD) of 8.4. The youngest patient was 16-years-old and the oldest 51-years-old at the time of surgery. In total, seven skeletal parameters, eight soft tissue parameters, and two dental parameters were evaluated on the cephalograms.Result:At the beginning of the treatment 49 Patients had SNA between 80° and 84°, 34 had SNA of less than 80° and 13 had SNA of more than 84°. Post surgically, 25 patients had SNA of 78°–84°, 19 had SNA less than 78° and 52 patients had SNA of more than 84°. Out of 96 patients 22 had SNB of 78°–82° before surgery, 16 had less than 78° and 58 had SNA of more than 84°. Postoperatively, we measured SNB of 78°–80° in 42, less than 78° in 18 and of more than 82° in 36 patients. The inclination of the maxilla relative to the cranial base changed from 7.2° (SD = 4)–8° (SD = 5.1) and the mandible changed from 35.7° (SD = 6.6) to 36° (SD = 6.3) postoperatively which was not significant. The distance from upper lip to E-line increased by 2.6 mm (SD = 3.9) after surgery (P < 0.001), while, the lower lip distance to E-line decreased slightly by 0.9 mm (SD = 3.2) (P < 0.01). Nasolabial angle was decreased by 9.5° (SD = 9.4) after surgery (P < 0.001). The nose prominence also decreased from 18.2 mm (SD = 3.5) –16.5 mm (SD = 3.3).Conclusion:Although in many cases we did not have a SNA angle or SNB angle in normal range but a good aesthetic outcome have been observed. Consequently our study showed that soft tissue change and aesthetic aspects should be considered in surgical planning and achieving SNA angle or SNB angle of norm range should not be the only goal. As we could show the advancement of maxilla will result in a better lip and nose profile and this should be considered in treatment planning.

“…There is no consensus about the changes in nasolabial angle in the literature. There are studies 4,22,23 reporting significant changes of nasolabial angle, whereas others 4,8 did not find any significant changes. In our study, the nasolabial angle did not change despite the upward movement of the nose.…”

“…They reported that the length of the base of the nose (Sn-Prn) decreased by 0.04 to 0.05 mm for each millimeter of maxillary advancement. The study by Esenlik et al 22 is the only study that investigated the changes occurring in the dorsum of the nose. They compared the nasal profile changes of patients who underwent maxillary advancement and maxillary advancement with impaction.…”

Objective: To determine the nasal soft-tissue profile changes in skeletal Class III patients who underwent maxillary or bimaxillary orthognathic surgery. Materials and Method: This clinical retrospective study consists of 40 patients (19 male and 21 female) who had undergone orthognathic surgery. All patients received single jaw maxillary (9 patients) or bimaxillary surgery (31 patients). Standardized lateral cephalograms obtained before operation and at least 6 months after the operation were used. Twelve measurements (4 skeletal and 8 soft-tissue measurements) were made. The distributions of the variables were checked by Shapiro-Wilk test. Paired-samples t test was used for parametric data and Wilcoxon sign rank test for nonparametric data, to analyze the differences between pre-and postoperative measurements. Results: After orthognathic surgery, SNA and ANB increased; SNB decreased significantly. A significant reduction in nasofrontal angle, TH-Prn, and nasal tip projection and a significant increase in nasofacial angle were found. In addition, superior movement of the nasal tip was found, and as a result, the nasal hump decreased. The N-Sn/Pr ratio, nasal tip angle, and nasolabial angle did not show any significant changes. Conclusion: It can be concluded that more vertical nasal changes rather than sagittal nasal changes are observed after maxillary surgery.

“…The state of the art in orthognathic surgery has advanced considerably during recent decades; however, information concerning soft tissue prediction, especially changes in the nasal profile, is still limited. A number of researchers have reported secondary morphologic changes with maxillary surgery (Freihofer, 1977; Gassman et al, 1989; Betts et al, 1993; Enacar et al, 1999; Day and Lee, 2006; Honrado et al, 2006; Bailey et al, 2007; Altuğ-Ataç et al, 2008; Chung et al, 2008; Anic-Milosevic et al, 2010; Esenlik et al, 2011; Kim et al, 2011; Mısır et al, 2011).…”

“…Advancement of the maxillary anterior segment causes a forward and upward movement of the premaxilla, and these alterations improve the soft tissue profile (Freihofer, 1977; Gassman et al, 1989; Betts et al, 1993; Enacar et al, 1999; Day and Lee, 2006; Honrado et al, 2006; Bailey et al, 2007; Chung et al, 2008; Esenlik et al, 2011; Kim et al, 2011; Mısır et al, 2011).…”

Introduction : The purpose of this study was to quantify anteroposterior facial soft tissue changes with respect to underlying skeletal movements after Le Fort I maxillary advancement surgery by using lateral cephalograms taken before and after the operation. Materials and Methods : The study group consisted of 20 patients (10 women, 10 men; mean age 23.4 ± 1.4 years) having a Class III skeletal deformity caused by a retrognathic maxilla. All patients were treated by Le Fort I maxillary advancement osteotomy. Lateral cephalograms were taken before and 1.6 ± 0.4 years after surgery. Results : The anteroposterior position of A-point and anteroposterior position of maxillary incisor were significantly protracted (-2.69 ± 3.34 and -2.68 ± 3.21, respectively; P < .01). The nasal anteroposterior and superoinferior positions (NASALAP and NASALSI, respectively) were significantly changed (-2.70 ± 6.81, P < .01, and -2.55 ± 5.80, P < .05, respectively) and nasal elevation and protraction were observed after Le Fort I maxillary advancement surgery. Conclusions : The changes in anteroposterior and superoinferior positions of A-point were correlated with the nasal superoinferior position (r = -0.71 , P < .05; r = 0.72, P < .05) after Le Fort I maxillary advancement surgery.
