BACKGROUND: Large tumors arising from the middle scalene region can displace the middle scalene muscle and distort regional anatomy, placing nerves at risk. Understanding the surgical anatomy of these nerves is key to approaching pathology of the middle scalene muscle and avoiding damage to the dorsal scapular, long thoracic, and spinal accessory nerves, each of which can cause scapular winging and associated morbidity if injured.
METHODS: IRB approval was obtained for this study, allowing cases with relevant pathology to be reviewed and presented to highlight the relevant surgical technique. Anatomical depictions were created to correlate intraoperative images with known anatomical relationships.
RESULTS: Key to this approach is consideration of the regional anatomy in a standard supraclavicular approach, the superficial plane, containing the anterior scalene muscle and brachial plexus, and the oblique plane containing the middle scalene muscle, long thoracic, spinal accessory, and dorsal scapular nerves. Identification and mobilization of each of these structures prior to lesion removal can not only provide likely boundaries of the tumor, but also allow for protection of the nerves to avoid injury that may lead to scapular winging with associated morbidity and functional impairment of the upper extremity.
CONCLUSIONS: Lesions of the middle scalene region often split two important anatomical planes, the superficial and deep, creating an advantageous surgical corridor through an anterolateral approach. Through early identification of known anatomy, these two planes can be developed, and a safe approach to the lesion of the middle scalene region can be exploited.
