In the published article, there was an error in Table 2 as published. The margin status of pathology in the table was 240 (96.8%) in the CNSM group and 32 (94.1%) in the RNSM group (p = 0.404). The correct values of margin status are 245 (98.8%) in the CNSM group and 33 (97.1%) in the RNSM group (p = 0.423). The corrected Table 2 Surgical methods and post-operative outcomes and its caption “Surgical methods and post-operative outcomes” appear below.
