Objective This study aims to evaluate the relationships between the anterior ethmoidal artery (AEA) notch landmark, Keros classification, and the presence and volume of supraorbital ethmoidal cells (SOECs) to determine their anatomical correlations and surgical implications. Materials and Methods A retrospective analysis of 102 paranasal sinus CT scans (204 sides) was performed. The AEA notch landmark was classified into three degrees based on its vertical distance from the skull base. The presence and volume of SOECs were recorded, and Keros classification was assessed. Correlations among these parameters were analyzed using Spearman's rank correlation coefficient, Chi-square, and Fisher's exact tests. Results SOECs were identified in 39.22% of cases, with a mean volume of 0.3535 +/- 0.109 cm(3) on the right side and 0.3399 +/- 0.054 cm(3) on the left. A significant correlation was observed between Keros classification and the AEA notch landmark (Spearman's rho = 0.637, p < 0.05). Additionally, SOEC volume showed a weak but significant correlation with the AEA notch landmark (Spearman's rho = 0.161, p < 0.05). However, there was no significant correlation between SOEC volume and Keros classification (p > 0.05). Conclusion AEA positioning is significantly influenced by both its distance from the skull base and SOEC volume, though SOEC volume does not affect Keros classification. These insights contribute to a better understanding of endoscopic sinus surgery anatomy and may help minimize surgical risks.

Inflammatory and infectious conditions of the larynx and hypopharynx have diverse etiologies, some of them rather uncommon, making clinical diagnosis challenging. Imaging plays a crucial role in assessing the characteristics, extent, and patterns of involvement of the disease, thereby contributing to the establishment of an accurate diagnosis. In acute infections with severe airway involvement, rapid and accurate treatment is imperative before further investigation. This review covers a wide range of pathologies, demonstrating their CT and/or MR findings. Knowledge of these differential possibilities will aid radiologists in accurately interpreting imaging studies.Learning Objective: To recognize clinical aspects and imaging findings of inflammatory and infectious diseases of the larynx and hypopharynx, providing support to differentiate them from neoplastic processes.

It is with great pleasure that we introduce to our readership Dr Camilo Jaimes and Dr Jungwhan del Rosario in Bogota, Colombia. Upon graduation, Dr Jaimes completed Diagnostic Radiology residency and Neuroradiology fellowship at Massachusetts General Hospital (MGH)-Harvard Medical School, followed by a fellowship in Pediatric Neuroradiology at Boston Children's Hospital where he started his brilliant career in 2019. Dr Camilo Jaimes served as Director of Faculty Affairs, Associate Fellowship Program Director, and Associate Chief of MRI. In his current role at MGH, Dr Jaimes is the Chief of Pediatric Neuroradiology, Co-Director of the Pediatric Imaging
