title: Management of parotid gland surgery in a university teaching hospital.
abstract: The aim of our study was the evaluation of two controversial procedures used in surgical management of parotid tumours in a university teaching hospital: fine needle aspiration cytology (FNAC) and continuous operative facial monitoring with nerve integrity monitor (NIM). We present a retrospective study of 96 consecutive cases of parotid gland surgical procedures, performed in our department of ENT Surgery (Bichat University Hospital) during a 2-year period. After the exclusion of nine patients (4 recurrent tumours, 3 insufficient data and 2 obviously malignant tumours with preoperative facial paralysis and necessary peroperative facial nerve sacrifice), the final group included 40 men and 47 women (mean age 46 years). FNAC, final histological diagnosis, NIM use, postoperative facial disorders and operative time were analysed. Other variables included age, sex, type of surgery and other postoperative complications. FNAC: 78 patients underwent FNAC. Positive predictive value for malignancy was 100%; negative predictive value 94.4%; sensitivity 63.6%; specificity 100%. NIM: surgery was performed without NIM for 41 patients, with for 46 patients. There was no significant difference in occurrence of facial disorders between the two groups. Operative time was significantly lower in group operated with NIM for extracapsular dissection, superficial parotidectomy and total parotidectomy. Because continuous efforts of modern health systems to improve operating room schedules may threaten resident surgeons training, using NIM and performing preoperative FNAC may help operative planning and improve medical education in a teaching hospital.
