Objective: The aim of this retrospective study was to investigate the effects of different vertical growth pat- tern on sagittal structures. Methods: The material consisted of cephalometric films of untreated 50 Class II subjects, 24 boys and 26 girls, aged 9 to 12 years. Subjects were divided into three groups with increased vertical facial growth pattern (SN/ GoGn>320), normal vertical facial growth pattern (280 ≤SN/GoGn≤320) and decreased vertical facial growth pattern (SN/GoGn<280). Differences between vertical groups were assessed by the means of variance analyses and least significant difference (LSD) test. And correlation coefficient between vertical groups and other vari- ables were calculated. Results: SNA (P < .01), SNB (P < .05), Gonial angle (P < .001), Jarabak ratio (P < .001) and IMPA (P < .01) were found to be related with vertical growth pattern. Negative correlation was found between SN/GoGn and SNA, SNB, IMPA angles and Jarabak ratio, and also positive correlation was observed between SN/GoGn and Gonial angle. Conclusion: The change in vertical growth pattern influenced sagittal parameters of face.
