Abstract
Background: Orthodontic and surgical modifications have been shown to have aesthetic effects on the shape or position of the nose. Aim: To evaluate nasal changes using cephalometric assessment after orthognathic surgery. The PIDAQ was cross-culturally adapted into Malay version by forward- and backward-translation processes, followed by psychometric validation.
Methods: A cross-sectional study was carried out involving 20 Moroccan orthognathic patients from January to March 2019. Their mean age was 22.40 (+/-6.98 years). The amplitude of the surgical movements of all patients was measured using measurements on profile teleradiographs and photos of faces taken before and after surgery. The statistical analysis of cephalometric data before and after surgery was performed using the Wilcoxon test. The significance level was p≤0.05.
Results: The results revealed a significant reduction in the angular values of SNA (°) (p<0.001), GoGn/SN (°) (p=0.038), Occ/Sn (°) (p=0.007) and AoBo (mm) (p=0.025). No statistically significant differences were noted for specific cephalometric variables before and after surgery as for facial photographs. All the values of the specific measurements before and after were significant except Prn - SN.
Conclusion: The width of the base of the nasal wing and the displacement and the amount of rotation of the nasal tip increased considerably in most patients while the X-axis to Prn distance decreased.
