(a-b) Anatomic landmarks and reference planes used in submentovertex cephalometric analysis (Tracing 2). SPR, right foramen spinosum: geometric centre of right foramen spinosum; SPL, left foramen spinosum: geometric centre of left foramen spinosum; TSA, transspinosum axis: line passing through the geometric centre of right and left spinosum points; MSP, midsagittal axis: perpendicular bisecting TSA; RCoL, right condylion lateralis: most lateral aspect of right condyle; RCoM, condylion medialis: most medial aspect of right condyle; LCoL, left condylion lateralis: most lateral aspect of left condyle; LCoM, left condylion medialis: most medial aspect of left condyle; RCoL-MSP, right condylion lateralis-midline: distance from right L-point to MSP; RCoM-MSP: right condylion medialis-midline: distance from right M-point to MSP; LCoL-MSP, left condylion lateralis-midline: distance from left L-point to MSP; LCoM-MSP, left condylion medialis-midline: distance from left M-point to MSP.
