Fourier analysis, in contrast with the conventional metrical approach, is particularly well-suited for studies of longitudinal growth since the method permits the accurate measurement of irregular morphological shapes. A longitudinal analysis of lateral cephalometric radiographs (15 males and 15 females) revealed the presence of an adolescent growth spurt in the cranial bones. The individual growth curves were aligned on the age interval where the maximum percentage change in growth occured. The presence of the pubertal spurt in the cranial bones suggests that the assumption of a lack of neural tissue involvement in the adolescent growth spurt is questionable.
