AI Article Synopsis
- Asterion is a key surgical landmark located at the junction of several skull sutures, traditionally believed to align with the transverse-sigmoid sinus junction (TSSJ).
- This study aimed to assess the accuracy of asterion as a TSSJ landmark specifically within the Indian population, using a sample of 16 dried skulls from AIIMS, New Delhi.
- The findings revealed that asterion is not a reliable TSSJ marker, with noteworthy average distances indicating that TSSJ is positioned significantly anterior and mostly inferior to asterion, suggesting the need for further research with larger sample sizes.
Article Abstract
Background: Asterion is the junction of lambdoid, parietomastoid, and occipitomastoid sutures. In traditional anatomy teaching, it is believed that asterion sits over the transverse-sigmoid sinus junction (TSSJ). It is a significant surgical landmark for the placement of a burr hole in the retrosigmoid approach.
Objective: The purpose of this study was to evaluate the asterion's accuracy as a TSSJ-specific external surgical landmark in the Indian population.
Materials And Methods: 16 human dried skulls were obtained from the Department of Anatomy, AIIMS, New Delhi. The point of TSSJ was taken between the two lips and just posterior to the entry of the superior petrosal sinus. Asterion internally was localized with the help of a geometrical divider. The x- horizontal/ anterior and y- vertically superior (+)/ inferior (-) distances were measured from asterion (internally) to the TSSJ by a digital vernier caliper.
Results: The mean horizontal distance (x) of the left side asterion & TSSJ was 10.3±1.0mm whereas the vertical distance (y) ranged between +2 to -4.3 mm. The mean horizontal distance (x) of the right side asterion & TSSJ was 13.5±1.4mm whereas the vertical distance (y) ranged between +3 to -4.2 mm.
Conclusion: Asterion is not a reliable landmark for TSSJ in Indian skulls. The TSSJ with respect to asterion was found on average 10mm and 13.5mm anterior on the left and right side respectively, and mostly inferior (average 4.2mm) in 75% of the skulls. The TSSJ was closer to the asterion on the left side in comparison with the right side. However, further studies with a larger sample size will be needed to evaluate the population-specific relation of asterion with the TSSJ.

There has been remarkable growth in our understanding of the biologic behavior and molecular signature of thyroid malignancies, which has led to the introduction, application, and evolution of molecular testing of thyroid nodule FNA cytology. Next-generation sequencing molecular testing is an important, well-validated diagnostic tool for management of cytologically indeterminate thyroid nodules. It reduces unnecessary thyroid surgery for benign disease, avoiding associated surgical risks for the patient and reducing healthcare expenses.

Accurate acetabular component positioning is crucial for the success of total hip arthroplasty (THA). Malplacement of the acetabular component increases the risk of post-surgery complications, most notably dislocation.1 Furthermore, malposition can also result in wear of the polyethylene liner, limited range of motion, and osteolysis.

The present paper was designed to analyze the dimensions of such important bony structures and surgical landmarks, which are used by many clinicians in many surgical interventions, in dry skull, cadaver, and healthy subjects on computed tomography (CT) images, and to determine whether there is a significant difference between these methods, and to obtain reference values from 3 different methods. Eight cadavers and 16 dry skulls and 100 three-dimensional (3D) CT images were studied. Necessary permissions for the study were obtained from Ethics Comittee.

Objective: The primary aim of this study was to investigate the accuracy of a semi-automatic algorithm in assessing the feasibility and complexity of endoscopic stapes surgery preoperatively.
Methods: A semi-automatic algorithm was developed to simulate endoscopic stapes surgery in 3D. To test the accuracy of the algorithm, five fresh-frozen cadaveric heads (ten ears) were used.
