    Summary
    This summary is machine-generated.

    Shoulder pain and trapezius weakness can occur after posterior cervical triangle surgery. This highlights potential spinal accessory nerve injury, even after minor procedures.

    Area of Science:

    • Neurology
    • Surgical Anatomy

    Background:

    • Benign lesions in the posterior cervical triangle are often removed via excision.
    • Post-operative complications require careful evaluation to differentiate nerve involvement.

    Observation:

    • Two patients developed shoulder pain following excision of posterior cervical triangle lesions.
    • One patient experienced delayed onset neck pain and trapezius weakness one month post-surgery.

    Findings:

    • The study identified specific signs of trapezius dysfunction, including difficulty elevating the arm without external rotation and scapular displacement during abduction.
    • These findings help distinguish spinal accessory nerve issues from serratus anterior weakness.

    Implications:

    • Spinal accessory nerve lesions should be considered in cases of shoulder pain and weakness after posterior neck procedures.

  • Early recognition is crucial for managing complications arising from minor surgeries, trauma, or conditions affecting the posterior cervical triangle.
