Objectives: To examine the correlation between spheno-occipital synchondrosis fusion stages and the hand-wrist skeletal maturity index.
Materials And Methods: Digital records of 164 individuals (77 males, 87 females) aged 10 to 18 years old were examined. Three-dimensional CBCT scans and hand-wrist two-dimensional radiographs were scored for the spheno-occipital synchondrosis fusion stages and hand-wrist skeletal maturity index, respectively. Statistical analyses were performed for associations using R software with a significance threshold of P< .01.
Results: A significant positive relationship was demonstrated between spheno-occipital synchondrosis fusion stages and hand-wrist skeletal maturity in both sexes. The Kendall's rank correlation τ between hand-wrist skeletal maturity index and spheno-occipital synchondrosis fusion percentage were high and positive in males and females (r = .74 and r = .71, respectively).
Conclusions: The significant, positive relationship between the hand-wrist skeletal maturity index and spheno-occipital synchondrosis fusion stages support the idea of using spheno-occipital synchondrosis fusion as a biological indicator for craniofacial and mandibular growth spurt prediction.

The impact of spheno-occipital synchondrosis exposure via extended endoscopic endonasal surgery on midface growth in pediatric patients.

Article Synopsis
- The study investigates the impact of drilling the spheno-occipital synchondrosis during endoscopic endonasal surgery (EES) on the growth of the midface in pediatric patients.
- It involved 14 patients under 12 years old with conditions like craniopharyngioma and others, with 8 undergoing an extended EES technique to enhance surgical exposure.
- The results showed no significant changes in facial growth angles post-surgery for the extended EES group compared to standard EES, indicating that the procedure may not adversely affect midfacial development.
Correlation of spheno-occipital synchondrosis and mandibular condylar cortication with chronological age using computed tomography in Indian population- A cross-sectional study.

Background: Forensic age estimation is a procedure which utilises many methods to estimate the age of both living and deceased individuals, including those who have died in natural disasters or man-made catastrophes. The pattern and closure of spheno-occipital synchondrosis (SOS) fusion, along with subchondral ossification of the mandibular condyle, can be used to estimate age.
Aim And Objectives: This study aims to estimate age using computed tomographic (CT) images of spheno-occipital synchondrosis fusion (SOS) and mandibular condylar cortication (MCC), and to correlate these findings with chronological age.
Objectives: To estimate the joint correlations among cervical vertebrae maturation (CVM), spheno-occipital synchondrosis (SOS), midpalatal suture maturation (MPS), and third molar mineralization (TMM) and to assess the predictive potential of SOS on CVM and MPS.
Materials And Methods: 570 pretreatment cone-beam computed tomogram (CBCT) scans from three private practices were analyzed, and MPS, CVM, SOS, and TMM stages were categorized and recorded by two independent investigators. Intra- and inter-rater reliability tests were evaluated with weighted Cohen's kappa tests.
Proposed complementary osteological indicators: Advancing the estimation of puberty stages in Bioarcheology.

Objectives: The study of puberty is a well-established area of bioarcheological research, which greatly enhances our understanding of adolescence and growth in the past. Since the publications of Shapland and Lewis' works, which have become "standards" for estimating puberty in skeletal material, no additional osteological indicators of puberty have been proposed. Nevertheless, clinical practice constantly develops skeletal maturation markers that could be useful in bioarcheology.

Article Synopsis
- The study investigates the spheno-occipital synchondrosis (SOS) fusion in patients with Muenke syndrome, a genetic condition associated with less severe facial deformities compared to other syndromes like Apert and Crouzon.
- Researchers evaluated CT scans from 28 Muenke syndrome patients and compared them to matched controls, focusing on SOS fusion status and facial measurements.
- The findings suggest that while Muenke syndrome patients exhibit minor retropositioning of the infraorbital rim, their SOS fusion patterns are similar to those of controls, indicating that any fusion timing differences might show up more at the infraorbital rim rather than the maxilla.
