CNVII PRESERVATION












                      On dissecting out CNVII which is circumferentially encased by tumour, there is bound to be

                      microscopic residual disease:






                      • Positive resection margins are associated with poor prognosis



                                                                                                                                         Oral Oncology 51 (2015) 770-777.






                      • Radiotherapy cannot substitute for CNVII resection in high risk patients


                                                                                                                                      Am J Clin Oncol 2014 PMID 25503431.






                      • Rate of CNVII palsy post conservative parotidectomy under the circumstances has been

                          reported to be up to 25%


                                                                                                                                         Acta Oto-Laryngologica 136:7, 711-716.
