Q: Does the closure of the spheno-occipital synchondrosis occur first in boys or girls?
show answer
A: The timing of the closure of the spheno-occipital synchondrosis is controversial. Still, the closure of this synchondrosis usually occurs faster and about 1 to 2 years earlier in girls than in boys.
Q: What is the classification system of the spheno-occipital synchondrosis closure?
show answer
A: The classification system of fusion of the spheno-occipital synchondrosis employs a staging system: stage 0 – unfused; stage 1 – fusing endocranially; stage 2 – fusing ectocranially; stage 3 complete fusion.
Q: What occurs with the spheno-occipital synchondrosis in patients with achondroplasia, Apert`s syndrome, and cleidocranial dysplasia?
show answer
A: The patients with these conditions show premature closure of the spheno-occipital synchondrosis.
Q: How can spheno-occipital synchondrosis help anatomists, anthropologists, forensic scientists, dentists, and radiologists?
show answer
A: Due to the variability in the age of the closure of the spheno-occipital synchondrosis, it plays a limited role as a guide by providing a general pattern in the estimation of age in different population groups, which has applications in the anthropological, forensic, dental, and medical fields.
Q: What is one differential diagnosis of spheno-occipital synchondroses?
show answer
A: The spheno-occipital synchondroses should not be mistaken for a fracture.
