Background: To observe anterior malar region clinically and cephalometrically and to correlate positive and negative vector with linear and angular measurements, as well as to check the reliability of these parameters. Material and Method: Lateral cephalograms and profile photographs, standardized by orienting the patient’s head with the Frankfort horizontal plane parallel to the floor. Each subject’s vector relationship was determined, using only profile photographs. Results: In positive vectors, the SNO and SNA is increased; Or-Pt A and O﬩NA distance is decreased and in negative vectors SNO and SNA is less, Or-Pt A and O﬩NA distance is more. Correlation amongst these parameters was significant. Conclusion: Positive vectors showed an increased malar support and negative vectors showed decreased malar support. Correlation between the photographs and cephalogram can help us to judge midfacial deficiency in a patient by just contemplating the photographs.
Keywords: Malar region, malar prominence, cephalometrics, cephalometric assessment, vector classification, positive vector, negative vector, midface deficiency.
