Dorsal C1–2 Spinal Cord Compression After Reduction of Atlantoaxial Posterior Dislocation Associated With Os Odontoideum: A Case Report and Literature Review

Orthopaedic Surgery, Volume 18, Issue 10, Page 2269-2275, October 2026.
Successful reduction of os odontoideum‐associated atlantoaxial posterior dislocation may not always guarantee adequate C1–2 canal space. In patients with congenital atlas hypoplasia or posterior arch osteophytes, postreduction dorsal cord compression should be anticipated, and C1 posterior arch decompression may be required to prevent neurological ...

Novel Surgical Strategy System for Juvenile Nasopharyngeal Angiofibroma: A Focus on Feeding Artery Management

World Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 4, Page 410-418, August 2026.
ABSTRACT Objectives For intraoperative bleeding control in patients with juvenile nasopharyngeal angiofibroma (JNA), we developed a novel surgical strategy system. This system is focused on feeding artery management, based on the spatial relationship between the tumor entity and feeding artery as determined by three‐dimensional reconstruction.

Bulbar “Red Flag” Symptoms and a 21‐Year Diagnostic Delay in Adult Arnold–Chiari Type II Malformation With Tracheoesophageal Fistula and Syringomyelia: A Case Report

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT The simultaneous occurrence of Arnold–Chiari Malformation Type II (ACM II), syringomyelia, and an acquired tracheoesophageal fistula (TEF) in a young adult is exceptionally rare and represents a major diagnostic challenge. Arnold–Chiari Malformation II is characterized by the herniation of cerebellar structures through the foramen magnum.

Test–Retest Reliability of Sensorimotor Activity Measured With Spinal Cord fMRI

Human Brain Mapping, Volume 47, Issue 10, July 2026.
fMRI captured sensorimotor activation in hand‐related spinal cord regions, in accord with the established neuroanatomical organisation of the cord. While task performance reliability was good‐to‐excellent, the reliability of spinal cord activation was mixed.
