Timing and rate of spheno-occipital synchondrosis closure and its relationship to puberty.

ABSTRACT:

Objectives

This study examines the relationship between spheno-occipital synchondrosis (SOS) closure and puberty onset in a modern American population. It also investigates the timing and the rate of SOS closure in males and females.

Materials and methods

The sample includes cross-sectional and longitudinal 3D Cone Beam Computed Tomography (CBCT) scans of 741 individuals (361 males and 380 females) aged 6-20 years. Each CBCT scan is visualized in the mid-sagittal plane, and the spheno-occipital synchondrosis (SOS) is scored as completely open, partially fused, mostly fused, and completely fused. The Menarche commencement is used as an indicator of puberty onset in females.

Results

Mean ages of open, partially-fused, mostly-fused, and completely fused SOS were 11.07, 1
