“…24 On the other hand, other studies showed slightly different growth rates in different age groups and suggested that cranial base growth was closely related to skeletal age. 20,27 Malta et al showed that the greatest amount of growth was 2.8 mm from time 1 to time 2, which correlated with CS1/2 change in growth to CS3/4. 27 Five studies showed size and growth differences between males and females as the cranial base dimensions increased, 24,25,28,32,36 whereas the other three studies indicated no difference according to sex.…”

“…16,[20][21][22]25,29,[34][35][36] In addition, there were variable changes in length and angulation among and between all stages of development. 13,27 Knott observed that the largest absolute change in linear dimension over a 9-year period, from ages 6 to 15, occurred in the postsphenoid region with an annual average of 1 mm. 35 During a similar age interval, other studies also showed similar age-related changes in SBa.…”

“…Of the 23 articles, 5 were cross-sectional in design, 13,[16][17][18][19] while the remaining 18 were cohort studies. 2,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] Samples consisted of craniofacial measurements from living or deceased postnatal human skulls. Validity of the measurements was not determined in any of the studies, while only six reported some form of reliability assessment.…”

Objective: To provide a synthesis of the published studies evaluating the natural growth and development of the human posterior cranial base (S-Ba). Materials and Methods: The search was performed on MEDLINE, Embase, PubMed, and all EBM Reviews electronic databases. In addition, reference lists of the included studies were handsearched. Articles were included if they analyzed posterior cranial-base growth in humans specifically. Study selection, data extraction, and risk of bias assessment were completed in duplicate. A meta-analysis was not justified. Results: Finally, 23 published studies were selected: 5 cross-sectional and 18 cohort studies. Articles were published between 1955 and 2015, and all were published in English. The sample sizes varied between 20 and 397 individuals and consisted of craniofacial measurements from either living or deceased human skulls. Validity of the measurements was not determined in any of the studies, while six papers reported some form of reliability assessment. All the articles included multiple time points within the same population or data from multiple age groups. Growth of S-Ba was generally agreed to be from spheno-occipital synchondrosis growth. Basion displaced downward and backward and sella turcica moved downward and backward during craniofacial growth. Timing of cessation of S-Ba growth was not conclusive due to limited identified evidence. Conclusions: Current evidence suggests that S-Ba is not totally stable, as its dimensions change throughout craniofacial growth and a minor dimensional change is observed even in late adulthood.
