AI Article Synopsis
- The atlas (first cervical vertebra) is crucial for understanding craniovertebral junction anomalies and their surgical correction.
- In a study measuring the superior articular facet (SAF) of 150 atlas specimens, it was found that the left SAF was significantly wider than the right, with various morphological shapes observed.
- Recognizing these size and shape variations of the SAF can aid in surgical procedures at the craniovertebral junction.
Article Abstract
Introduction: The first cervical vertebra, also referred to as the atlas, forms a vital part of the craniovertebral junction (CVJ). The anatomy of the atlas is essential to understand the basis for CVJ anomalies and their surgical correction. The present study was undertaken to provide accurate morphometry and describe the morphological variations of the superior articular facet (SAF) of the atlas. Methods: In this observational, cross-sectional study, the length and width of the SAF of 150 atlas were measured using a digital caliper. The variations in the morphology of the SAF in the same bones were also recorded. Z-test was applied to find the statistically significant difference between the measurements of the SAF of the atlas on the right and left sides. p-value ≤ 0.05 was considered statistically significant.
Results: The width of the SAF of the atlas was found to be significantly (p < 0.001) greater on the left side (8.76 mm to 14.84 mm) compared to the right (7.67 mm to 14.83 mm). The mean length of the SAF was 21.1 mm and 21.9 mm on the left and right sides, respectively. Morphologically, four variations of superior articular facets were noted: oval, bilobed, kidney, and dumbbell shaped. The most common variation was an oval-shaped facet with a prevalence of 66.7% on the left side and 57.3% on the right. The least common variation was the bilobed facet, with a prevalence of 4% on the left side and 8.7% on the right.
Conclusion: The width of the SAF of the atlas was statistically significant on the left side. Morphologically, four types of variations were observed in the shape of the SAF. Knowledge of the morphological and morphometric variations of the SAF can be of help during surgical approaches at the CVJ.

A term, healthy infant presented with respiratory distress and severe pulmonary hypertension (PH). With an unclear aetiology and the intent to decrease right ventricular afterload, pulmonary vasodilators were initiated. Follow-up imaging revealed a supravalvular mitral ring as the cause of the PH which resolved after surgical resection of the membrane.

Introduction: Allergic fungal rhinosinusitis (AFRS) is a distinct subset of chronic rhinosinusitis characterized by a type I hypersensitivity to fungi. Immunocompromised patients are at increased risk for fungal infections. This case highlights the complexities of managing AFRS in patients not eligible for surgery.

Background: Dizziness and balance disturbances are common in patients with MS. Subjective visual vertical (SVV) is a test of vestibular perception that allows clinicians to evaluate the integration of multiple sensory inputs for spatial orientation in the CNS. We hypothesize that central vestibular impairment caused by active MS lesions may be reflected in the modified SVV testing.

The hominin mandible SK 15 was discovered in April 1949 in Swartkrans Member 2, dated to ∼1.4 Ma. Albeit distorted on the right side, the left and right corpus of SK 15 are relatively low and thick, even compared to most Early to Middle Pleistocene Homo specimens.

This study aims to compare the accuracy of Demirjian's and Cameriere's methods in determining adult age at the 18-year threshold using mandibular third molars in the Thai population. Panoramic radiograph images of 504 healthy subjects aged between 14 and 23 years were retrospectively collected. The developmental stages of mandibular third molars were evaluated using Demirjian's method, while the maturity index of mandibular third molars (I3M) was assessed using Cameriere's method.
