Utilization and Effectiveness of Pectoralis Minor Tenotomy in the Surgical Management of Neurogenic Thoracic Outlet Syndrome.

BackgroundUncertainty exists concerning the optimal utilization and effectiveness of pectoralis minor tenotomy (PMT) in neurogenic thoracic outlet syndrome (NTOS).MethodsBetween January 2020 and July 2023, 355 patients with NTOS underwent primary surgical treatment. Prospectively collected data were analyzed retrospectively.ResultsOverall mean patient age was 35.9 ± 1.9 years, 76% were female, and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score at presentation was 60.3 ± 3.2, reflecting substantial disability. Surgical treatment was based on localized tenderness/symptoms to palpation, with 322 (91%) undergoing combined supraclavicular decompression and PMT (SCD + PMT) and 33 (9%) selected for isolated PMT when findings were solely confined to the subcoracoid space. Mean operative time (29 ± 5 vs 164 ± 9 min, P P P P P ConclusionsPectoralis minor tenotomy (PMT) has an important role in surgical treatment of NTOS, mainly as an adjunct in combination with SCD. While highly selected patients can do well after isolated PMT as a short outpatient procedure with rapid recovery, there is a greater potential for poor outcomes and supraclavicular reoperation than after SCD + PMT.
