The spheno-occipital synchondrosis (SOS) is a cartilage growth joint between sphenoid and occipital bone in the skull base. It helps lengthen the cranial base and, secondarily, the midface in childhood.[1] Looksmaxxing folklore treats SOS closure as “maxilla locked, it’s over.” Closure is gradual through adolescence; it is not a femur growth plate, and you cannot palpate it in a mirror.
Not a DIY. Not a reason to take growth hormone. See cranial suture and maxilla.
