At what age does the basiocciput and basisphenoid fusion typically occur?

The fusion of the basiocciput and basisphenoid typically occurs between the ages of 18 and 22 years. This is a significant developmental milestone in the human skull, as these two structures play a crucial role in the formation of the cranial base. Their fusion is part of the overall process of craniofacial development and indicates the completion of certain growth phases during late adolescence to early adulthood.

While individual variations can occur, this age range is well supported in anatomical studies and represents the time frame when many skeletal structures in the human body undergo changes to achieve their adult form. Understanding this timing is essential for professionals in fields such as forensic medicine, where knowledge of skeletal maturity can aid in age estimation of skeletal remains.
