New method in the age estimation by the spheno-occipital suture. 3D cone-beam CT application

The aim of the present study was to determine the sequence and timing of closure of the spheno-occipital synchondrosis for a large sample of a modern Italian population to assess if this age marker is a useful tool for age estimation for individuals. The sample consisted of 494 individuals in the age range 0-22 years, who were admitted to the Department of Radiology, Oncology and Anatomo-Pathology of "Sapienza" University of Rome - UOC Head and Neck Radiology - and the Department of imaging, University of L'Aquila, and who had undergone multi-slice CBCT imaging. The average age of the spheno-occipital closure in men is 18.3 years, whilst in women is 16.6. Therefore, it is evident that the closure in female people is faster than 1.7 years. The timing of closure of spheno-occipital suture can be used to understand the age, even if the research has to be implemented.
