During diagnosis and treatment planning of skeletal malocclusions proper evaluation of sagittal jaw relationship is an important step which is generally determined by cephalometric analysis. Any cephalometric analysis based on angular or linear measurement has obvious shortcomings and limitation. The most commonly used parameter is ANB angle which may vary since Nasion being unstable with age questions the reliability of ANB Angle as an indicator for apical base discrepancies.  Objective of The Study The study evaluates the most reliable parameter for assessing anteroposterior skeletal jaw relationship using angular measurements and their correlation with visual clinical examination.  Materials and Methods Total of 60 Lateral cephalograms in Raichur population, the cephalograms were grouped according to visual clinical examination as follows • Group 1- Class I (n=20) • Group 2- Class II (n=20) • Group 3- Class III (n=20) Lateral cephalograms in each group were traced and YEN angle, W angle, MKG angle and ANB angle were measured.  Results The study showed mean and standard deviation of YEN angle was 119 + 6.76, MKG angle was 51.05 +4.94, W angle was 52.28 +5.54 and ANB angle was 1.3 +2.67.

Keywords : ANB Angle, W Angle, Yen Angle, MKG Angle Skeletal Jaw.
