From this, we propose that parotid gland OpR should include more mandatory data: tumor size (<2 cm/2–4 cm/>4 cm), location (according to the ESGS), FN contact (main trunk, branches), presence or absence of satellite tumors, complete removal or ruptured tumor capsule, removed parenchyma (part/whole superficial lobe/deep lobe), post-operative FN function (intact or injured), and intraoperative difficulties (scars, adhesions, and excessive bleeding). This evidence concerns the gene FN1 and neoplasm.
