The occipital artery (OA) is an important donor artery for intracranial and extracranial bypass surgery, but its path is tortuous, making it difficult to harvest. Part of the traditional intermuscular OA is not covered by muscle and is easily damaged during surgery. Currently, there are few reports on how to protect this segment of the OA. ⋯ Through the far lateral approach, the splenius capitis muscle is a useful landmark to expose the OA. We can safely, quickly, and accurately find the OA by dissecting within 13.6 ± 5.2 mm below the uppermost muscle fiber of the splenius capitis muscle.

This study aimed to investigate the impact of paraspinal muscle (PSM) degeneration on coronal balance in patients with degenerative lumbar scoliosis (DLS). ⋯ PSM degeneration, particularly in the MF and ES muscles, significantly affects coronal balance in DLS patients. Preoperative evaluation of these factors is essential for optimizing surgical outcomes.
