Methods: A retrospective study of 69 procedures performed for nTOS between 2015 and 2024 by a single neurosurgeon. Surgical approaches, intraoperative findings, postoperative complications, and clinical outcomes were analyzed. Results were compared between the combined and isolated supraclavicular approaches using Chi-square testing and logistic regression models. Results: The overall complication rate was 18.8% (13/69). Complications occurred in 22.5% of combined procedures (9/40) and 12.0% of isolated supraclavicular procedures (3/25), with no statistically significant difference (P = 0.545). All complications were transient, most commonly phrenic nerve palsy (7.2%) and superficial wound infection (5.8%). No permanent brachial plexus or vascular injuries occurred. The combined approach provided significantly better exposure of both proximal and distal compression zones, enabling more complete decompression, which was reflected in a higher rate of clinical improvement (82% vs. 69% in isolated approaches). Conclusion: Although the combined approach presents a numerically higher complication rate, the difference is not statistically significant, and all complications were transient. Its superior anatomical exposure and higher rate of clinical improvement support the combined approach as a safe and advantageous surgical option for patients with suspected multilevel nTOS compression.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/51bb3dcb-cc90-4849-9874-557d681c886c/featured/hero-1781557910783.png","publishDate":"2026-02-13T00:00:00.000Z","doi":"10.25259/SNI_1362_2025","categories":["General Neurosurgery","Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/51bb3dcb-cc90-4849-9874-557d681c886c/pdf"}
