Skeletal pattern (Vertical : LAFH). Lower Anterior Facial Height (LAFH). Is used to assess vertical dimension Ratio of the LAFH to the total face height gives an indication if the LAFH is within normal limits Facial proportion (LAFH %) = MxPl to Me x 100 MxPl to Me + MxPl to N

Lower Anterior Facial Height (LAFH) • Is used to assess vertical dimension • Ratio of the LAFH to the total face height gives an indication if the LAFH is within normal limits • Facial proportion (LAFH %) = MxPl to Me x 100 MxPl to Me + MxPl to N = 55% ± 2%
