The objectives of this study were to determine normal reference values for ultrasonographic measurement of the cross‐sectional area (CSA) of the axillary nerve and to standardize the measurement methods. Methods Sixty healthy volunteers were evaluated. Ultrasonography was performed with the shoulder positioned in 100°–120° abduction and 90° external rotation. The CSA of the axillary nerve was measured bilaterally. Results The normal CSA of the right axillary nerve was 2.9 ± 1.1 mm 2 . The side‐to‐side discrepancy was 22.8% ± 17.8%. Discussion These reference values may be helpful for investigating pathologies involving the axillary nerve.
